On the 2011-2021 Jeep Grand Cherokee 5.7L HEMI V8 with MDS/VVT, a persistent tick and cylinder misfire on a 5.7L Grand Cherokee can be consistent with valvetrain damage, but those symptoms do not identify a failed MDS lifter or worn camshaft by themselves. Exhaust-manifold leaks, ignition or injector faults, oil-pressure problems, rocker/pushrod faults, compression loss, and other mechanical conditions can overlap. FCA has published a cam/lifter inspection note for certain 5.7L MDS police Charger, Durango, and Ram 1500 vehicles, but that document does not establish the prior card's blanket Grand Cherokee year, mileage, DTC, or part-set claims.
Common Symptoms
Persistent engine-speed tick that remains after warm-up
Cylinder-specific or random misfire
Rough running or reduced power
Abnormal rocker motion or confirmed cam-lobe/lifter-roller damage
Metal debris found during oil-filter inspection
How to Fix
Record the exact DTCs and freeze-frame data, verify oil level and mechanical oil pressure, and identify whether the sound is from the exhaust manifold or inside the valvetrain. Diagnose ignition and injector causes for the affected cylinder, then perform factory compression and cylinder-leakage testing as indicated. If the evidence remains mechanical, inspect rocker motion, pushrods, lifter rollers, and cam lobes using service information for the exact VIN and engine build. Only after lifter or cam damage is physically confirmed should a technician select the correct mix of deactivating and standard lifters, yokes, camshaft, gaskets, torque-to-yield fasteners, and any contamination-related work. Stop driving and obtain professional diagnosis if the oil-pressure warning appears, the malfunction lamp flashes, severe misfire develops, or metal is found in the oil/filter.
Owner tips & cautions
WarningDo not buy a camshaft or lifter kit from a tick, a generic misfire code, or the old card's part list. The correct repair depends on physical inspection and the VIN-specific MDS valvetrain configuration.
TipRule out the exhaust-manifold cold-tick condition first. FCA has a separate crack-inspection path and updated manifold kits for covered 2019-2022 5.7L vehicles.

On the 2011-2013 Jeep Grand Cherokee 3.6L Pentastar V6, early (2011-2013) 3.6L Pentastar engines have a defective left-bank cylinder head with excessive valve seat/guide wear, attributed to incompatible head materials. The wear causes leak-down and misfires concentrated on the left bank — cylinders 2, 4, and 6 — often with a ticking valvetrain noise. Chrysler never issued a safety recall but acknowledged the problem with TSB 09-002-14 and warranty extension X56, covering the left cylinder head for 10 years / 150,000 miles. Buyers are advised to confirm the left head is stamped 2062 (day 206 of 2012) or later, indicating the corrected casting.
Replace the affected (left) cylinder head with the updated revised-casting part, including new gaskets and hardware, per TSB 09-002-14. Verify warranty extension X56 coverage (10yr/150k) before paying out of pocket. Diagnose by pulling misfire codes on even-numbered (left-bank) cylinders and performing a leak-down/compression test; confirm the head casting date stamp on used/early engines.

On the 2018-2025 Jeep Grand Cherokee 3.6L V6 24V VVT Engine Upgrade I with ESS (ERC) or eTorque (ERG), fCA says a manufacturing issue on the 3.6L Pentastar Upgrade engine may cause wear at an intake camshaft high-lift lobe and/or an intake rocker-arm high-lift slider. The documented customer pattern is a cylinder-specific P0301-P0306 misfire with possible rough idle and valvetrain noise; FCA identifies 10,000-60,000 miles as the typical range. The bulletin covers 2018-2022 WK Grand Cherokee and 2021-2025 WL Grand Cherokee/Grand Cherokee L with ERC or ERG engines. WL vehicles are limited to those built on or before August 19, 2024 (MDH 0819XX). The previous card omitted the WK/WL split and build cutoff, described eTorque as the only engine, added P0300, and presented six separately purchased parts even though FCA provides complete side-specific service kits after diagnosis.
Malfunction indicator lamp with P0301, P0302, P0303, P0304, P0305, or P0306
Rough idle
Valvetrain noise
How to Fix
Record the exact cylinder-specific DTC, rough-idle complaint, and location/pattern of any valvetrain noise. Confirm WK versus WL, engine sales code, and—on WL—the August 19, 2024 build cutoff before using this bulletin. Follow current FCA misfire and valvetrain diagnosis to rule out unrelated causes and inspect the intake rocker high-lift sliders and intake cam high-lift lobes on the indicated bank. FCA says these symptoms may be related to wear; a misfire by itself does not prove the kit is needed. When the documented wear is confirmed, use FCA's special service kit for the affected bank instead of replacing the complete engine or assembling individual rockers, lifters, seals, and camshafts: 68661147AB for the right intake bank and/or 68661146AA for the left. Each kit contains the intake camshaft, rocker arms, sealer, and gaskets required by the bulletin. Verify the VIN and affected side before ordering either exact product below.
Owner tips & cautions
WarningDo not order a camshaft kit from a misfire code alone. FCA says the symptom may be related to cam/rocker wear, so the high-lift lobe and slider on the indicated bank must be inspected first.
TipConfirm right versus left bank before ordering. FCA provides two different complete kits, and each already includes the camshaft, rocker arms, sealer, and gaskets for that side.
WarningThe WL bulletin scope ends at the August 19, 2024 build cutoff even though model-year coverage extends through 2025. Verify the VIN/build record and ERC or ERG sales code.
On the 2014-2019 Jeep Grand Cherokee 3.0L EcoDiesel V6, certain 2014-2019 Jeep Grand Cherokee vehicles with the 3.0L EcoDiesel engine are included in safety recall W79 / NHTSA 20V-699. NHTSA lists 28,884 potentially involved Jeep vehicles. Thermal fatigue can cause the EGR cooler to crack internally over time, allowing pre-heated vaporized coolant into the EGR system; under some conditions the mixture can combust inside the intake manifold and lead to a vehicle fire. Recall inclusion is VIN-specific. The prior card overstated the Jeep population as 34,334, attached unsupported generic EGR codes, and offered OEM, aftermarket, manifold, and gasket purchases even though the recall repair is free and inspection-dependent.
Evidence of intake-manifold damage when the FCA inspection criteria are met
How to Fix
Check the VIN for open recall W79 and schedule the free repair with an authorized Jeep dealer. FCA's procedure replaces the EGR cooler using campaign parts. If the malfunction indicator lamp is illuminated, the dealer checks for P0299 and P2D2F; when either is present, the intake manifold is inspected and leak-tested and is replaced only if perforation is confirmed. Monitor the coolant level as FCA advises and contact the dealer if it is consistently low. If there is smoke, a burning smell, visible fire, or rapid coolant loss, stop safely, shut the engine off, move occupants away, and seek emergency/towing assistance. Do not buy an EGR cooler, manifold, aftermarket cooler, or gasket bundle in place of the VIN-specific recall remedy.
Owner tips & cautions
WarningDo not substitute an aftermarket EGR cooler for an open safety recall. Confirm W79 by VIN and use the free dealer remedy.
TipThe intake manifold is not an automatic add-on. FCA calls for inspection and leak testing when P0299 or P2D2F is present, with replacement only if perforation is found.
WarningThe corrected Jeep population is 28,884 potentially involved vehicles; 34,334 was not the Jeep-only total in NHTSA's report.
On the 2014-2019 Jeep Grand Cherokee 3.0L EcoDiesel V6, GEN-2 (sales codes EXF or EXN), fCA identifies the 2014-2019 Grand Cherokee 3.0L diesel as a GEN-2 engine. Its replaceable filter element looks similar to the GEN-3 cap-and-element design used in newer diesel applications, but the two designs are not interchangeable. FCA warns that putting a GEN-3 element in a GEN-2 cap, or the reverse, can circulate unfiltered oil and cause premature engine wear. The previous card instead claimed that casting debris commonly punctures the oil cooler, causes oil/coolant cross-contamination around 100,000-140,000 miles, and justifies an oil-cooler assembly, coolant, and filter purchase. The reviewed FCA evidence does not establish those claims, so they and their search links were removed.
Common Symptoms
A service invoice or replacement cartridge identifies a GEN-3 cap-and-element design
The removed filter element is deformed after being installed in the wrong cap
Abnormal engine noise or an oil-pressure concern after an oil service
How to Fix
Confirm that the vehicle is a 2014-2019 WK Grand Cherokee with the GEN-2 3.0L diesel. Use a GEN-2 filter element specified for that exact application; on GEN-2 the element is replaced separately from the existing cap. Do not install a GEN-3 cap-and-element cartridge or detach a GEN-3 element for use in the GEN-2 cap. Compare the old and new element before installation and use the filter manufacturer's supplied seal. If a wrong-generation filter was installed, remove it, inspect it for deformation, restore the correct GEN-2 element, and have the lubrication system and engine condition assessed if the vehicle was operated or has abnormal noise or oil-pressure concerns. The exact WIX link below is limited to the original 2014-2019 3.0L GEN-2 application; verify the VIN and engine before ordering.
Owner tips & cautions
WarningDo not buy an oil cooler from the old card. The reviewed FCA bulletin documents a filter-generation mismatch risk, not the old casting-debris and universal cross-contamination claim.
WarningThe linked filter is for the original 2014-2019 GEN-2 3.0L application. Never substitute the newer GEN-3 cap-and-element design because the cartridges look similar.
On the 1999-2004 Jeep Grand Cherokee 4.7L V8 (PowerTech; standard or High Output where equipped), a missing crank-reference signal can cause a crank-no-start or an engine stall on the 4.7L Grand Cherokee. In the factory diagnostic, P0320 means the PCM did not receive the expected crankshaft-position signal during cranking after camshaft-position signals occurred. The possible causes include an intermittent CKP signal, cam signal, 5-volt supply, sensor ground, CKP signal wiring, the sensor, or the PCM. The prior card called heat-soak sensor failure common, included P0335 and P0339, and implied the same path for the 4.0L without primary support for those claims.
Common Symptoms
Engine cranks but does not start
Intermittent engine stall
P0320 no-crank-reference-signal fault
Missing crankshaft-position signal during cranking
How to Fix
Capture codes and scan data during the failure. For P0320, follow the 4.7L factory test sequence: inspect the CKP and cam connectors and harness routing, verify the 5-volt supply and sensor ground, test the signal circuit for opens/shorts, and confirm the crank-reference signal before condemning the sensor or PCM. If diagnosis identifies the CKP sensor, verify the VIN/engine against Mopar 56028666AB and its supersessions before ordering. The factory procedure places the sensor in the block above the starter and requires starter removal; inspect and lubricate the sensor O-ring, seat the sensor flush, and use the service-manual torque. Clear codes and verify the signal and restart behavior after repair.
Owner tips & cautions
WarningDo not replace the sensor from P0320 alone. The factory tree also lists CKP supply, ground, signal wiring, cam signal, and PCM causes.
WarningRecall 04V-112 is a limited 2004 4.0L campaign; it does not make a 1999-2004 4.7L sensor replacement a recall repair.
TipThe 4.7L sensor sits above the starter. Follow the factory O-ring, flush-seating, and torque precautions so the new sensor is not damaged during installation.
On the 2023-2025 Jeep Grand Cherokee 2.0L Turbo I4 plug-in hybrid (4xe), certain 2023-2025 Jeep Grand Cherokee 4xe vehicles are included in FCA safety recall 78C / NHTSA 25V-766. FCA's amended report lists 39,975 potentially involved Grand Cherokee PHEVs built from July 19, 2023 through April 10, 2025. Sand left from the engine-block casting process can contaminate internal components and lead to catastrophic engine failure, an engine-compartment fire, or an unexpected and unrecoverable loss of propulsion. FCA says a knocking noise from the engine compartment and/or a malfunction indicator lamp may occur before failure, but recall inclusion is VIN-specific.
Common Symptoms
Knocking noise from the engine compartment
Malfunction indicator lamp
Unexpected loss of propulsion
Engine-compartment smoke or fire
How to Fix
Check the VIN for open recall 78C and contact an authorized Jeep dealer. FCA's current remedy reprograms the Powertrain Control Module with software that detects and monitors for potential pending engine-bearing failure. If the software confirms bearing failure, FCA replaces the long block or engine. FCA's March 2026 report also identifies warranty extension XC2 with unlimited years and unlimited mileage for impacted customers who receive defect-related messaging and need a long block or engine. Follow the official do-not-drive and park-outside advisories until the VIN-specific remedy is completed; if knocking, a malfunction light, smoke, fire, or loss of propulsion occurs, stop safely, move occupants away, and arrange dealer/towing or emergency assistance as appropriate. Do not self-source an engine for a free safety-recall repair.
Owner tips & cautions
WarningRecall eligibility is VIN-specific. Use the NHTSA or Jeep VIN lookup and follow FCA's do-not-drive and park-outside advisories until recall 78C is completed.
TipThe current recall remedy starts with PCM software monitoring; a long block or complete engine is replaced only when the remedy confirms the covered bearing-failure condition.
WarningDo not buy the old 68412483AF retail engine link. FCA's free VIN-specific recall process and warranty extension determine the covered replacement.
On the 2011-2013 Jeep Grand Cherokee 3.6L Pentastar V6 (sales code ERB), fCA TSB 09-002-14 Rev. B covers 2011-2013 WK Grand Cherokee vehicles with the 3.6L ERB engine when P0300, P0302, P0304, or P0306 is stored. The bulletin's decision point is excessive leakage in the cylinder that set the misfire, not a tick, mileage estimate, casting date, or assumption that every left-bank misfire needs a cylinder head. X56 was an extended warranty, not a safety recall. Warranty bulletin D-14-12 set original coverage at 10 years or 150,000 miles from the vehicle's in-service date for eligible VINs; current eligibility must be checked and should not be described as an automatic free repair in 2026.
Malfunction indicator lamp with P0300, P0302, P0304, and/or P0306
Rough running or misfire on an affected cylinder
Cylinder leakage of 25 percent or greater on the misfiring cylinder
How to Fix
Save the misfire DTC and freeze-frame data and first exclude normal ignition, injector, wiring, fuel, and other mechanical causes as appropriate. For a vehicle within the FCA bulletin path, perform a cylinder leakage test on the cylinder that set the misfire. FCA directs left-cylinder-head replacement only when that cylinder shows 25 percent or greater leakage; below 25 percent, the bulletin does not apply and normal diagnosis continues. Check the VIN in the dealer system for any remaining X56 status or prior repair history. If replacement is required outside coverage, have the technician confirm the current Mopar supersession, complete gasket/bolt/seal list, machine condition, core terms, and all one-time-use components for that VIN before ordering. Recheck compression/leakage, misfire counts, cooling, oil level, and leaks after repair.
Owner tips & cautions
WarningDo not order a cylinder head from a tick or misfire code alone. FCA requires leakage testing on the cylinder that set the DTC and a result of at least 25 percent before this bulletin's head-replacement path applies.
TipAsk the dealer to check the VIN for X56 status and repair history even though the original time limit may have expired; coverage was VIN-, time-, and mileage-dependent.
On the 1999-2004 Jeep Grand Cherokee 4.0L I6 (PowerTech 242); identify the installed cylinder-head casting before ordering, a cracked cylinder head or failed head gasket can produce coolant loss, overheating, rough running, or cylinder leakage on a 4.0L Grand Cherokee, but the previous card treated every 1999-2004 vehicle as if its installed casting and failure mode were already known. Heads may have been replaced during the vehicle's life, and DaimlerChrysler also documented P0300 and single-cylinder misfires from slow-closing exhaust valves caused by carbon. A model year, a P030x code, or coolant loss by itself does not prove a crack between cylinders 3 and 4 or identify the correct replacement head.
Common Symptoms
Unexplained coolant loss after external leaks are checked
Overheating or unstable coolant temperature
Rough running or a cylinder-specific misfire
Combustion gas in the cooling system
Oil and coolant cross-contamination
How to Fix
Start with the cooling system and the actual failure path: pressure-test the system cold, inspect external leak points, test for combustion gas where appropriate, and inspect the oil and coolant for cross-contamination. For a misfire, follow the factory diagnostic path and use compression and leak-down results rather than assigning the code to the head. Record the installed casting/foundry markings because a prior repair may have changed the head. If removal is justified, have the head and deck inspected and pressure-tested by a qualified machine shop. Only after the crack, deck condition, installed casting, and required machining are known should the shop select an application-specific head, gasket set, and fastener plan. No universal replacement head is linked here.
Owner tips & cautions
WarningDo not buy a cylinder head from the model year alone. Read the markings on the head that is actually installed; a previous engine repair may have changed the casting.
WarningP0300 or a cylinder-specific misfire does not prove a cracked head. DaimlerChrysler documented another 4.0L cause—slow-closing exhaust valves from carbon—within this same WJ year range.
TipBefore ordering repair parts, preserve the pressure-test, combustion-gas, compression, leak-down, casting-identification, and machine-shop findings so the part choice matches the confirmed failure.
On the 2011-2014 Jeep Grand Cherokee 3.6L Pentastar V6 (sales code ERB), original factory oil-filter adapter, chrysler changed the 3.6L engine oil-filter adapter and filter element for model year 2014. The 2011-2013 and 2014 designs are physically different and are not interchangeable; Chrysler warns that installing the wrong filter causes permanent engine damage. The included O-ring must also be used because the wrong seal can leak and damage the adapter. The previous card duplicated the separate adapter-leak record, claimed a common plastic-housing failure across 2011-2023 WK2 and WL vehicles, said Chrysler discontinued the plastic assembly, and directed every owner to an aluminum replacement without separating model year or installed housing.
Common Symptoms
A replacement filter does not match the element removed from the original housing
The filter or supplied O-ring will not seat correctly
A service record lists the 2011-2013 element for a 2014 vehicle or the reverse
How to Fix
Confirm the model year and inspect which oil-filter adapter is actually installed. For an original factory adapter, use the early element family for 2011-2013 and the later element family for 2014; never interchange them. Use only the O-ring supplied with the selected filter and install it in the correct groove. The two exact product links below are year-split and apply only to original factory-style housings. If an aftermarket aluminum adapter or conversion has been installed, do not use these links from model year alone: identify the housing manufacturer and part number and use the filter and seal that manufacturer specifies, because ShowMeTheParts explicitly lists different elements for some aftermarket housings. If a wrong filter was installed, correct it and have the engine assessed if it was operated or has abnormal noise or oil-pressure concerns.
Owner tips & cautions
WarningThe 2011-2013 and 2014 filters are not interchangeable. The two product links are intentionally separated by model year and original factory housing.
WarningAn aftermarket aluminum housing can change the required filter. Identify that housing and follow its own application instructions instead of ordering from the vehicle year alone.
TipCompare the new element and supplied O-ring with the parts removed before installation; use only the seal included with the correct filter.
On the 1999-2009 Jeep Grand Cherokee, the 4.7L V8 used in Grand Cherokee models is widely reported to develop broken exhaust manifold bolts or warped manifold sealing surfaces, especially after repeated heat cycles. Owners typically notice a ticking noise on cold start that may quiet as the engine warms, sometimes mistaken for valvetrain noise. Left unrepaired, the leak can worsen and may contribute to exhaust odor or failed emissions inspection.
Confirm the leak with a cold-start inspection, listening near the manifold and checking for soot around the flange and broken fasteners. Repair usually involves extracting broken studs/bolts, resurfacing or replacing the manifold if warped, and installing new hardware and gaskets. Penetrating oil, heat, and careful extraction are often required because broken fasteners in the cylinder head are common.
Owner tips & cautions
TipOwners recommend replacing all manifold hardware on the affected side once one bolt breaks, rather than only the visibly failed fastener.
TipA smoke test or cold-start stethoscope check helps distinguish manifold leaks from injector or valvetrain noise.
On the 2012-2021 Jeep Grand Cherokee 3.6L Pentastar V6, oil found around the Pentastar oil filter adapter does not prove that the complete adapter or oil cooler has cracked. FCA's service guidance separates several repair paths: a cap O-ring that is cut, damaged, or installed in the wrong groove; five adapter bolts that are not at the specified torque; and a confirmed leak at the adapter-to-block O-rings and gaskets. FCA's 2021 guidance tells technicians to reseal a confirmed interface leak rather than replace the adapter on the covered non-2014 vehicles, while model-year 2014 is handled as an adapter-replacement exception. The previous card treated 2011-2020 vehicles alike, prescribed an aluminum assembly, implied oil/coolant cross-contamination, and listed P0128 and P26B7 without reviewed support.
Oil collecting in the engine valley or running down the engine
A leak that reappears in dye tracing at the adapter-to-block interface
How to Fix
Clean the area and add approved oil dye so the source can be observed before parts are ordered. Inspect the oil-filter-cap O-ring for damage and confirm it is seated in the correct groove. Check the five oil-filter-adapter bolts against FCA's 12 N-m specification and document any under-torque condition. If dye confirms a leak at the adapter-to-block interface, follow the current VIN- and model-year-specific FCA service information: the cited guidance calls for O-ring/gasket kit 68191356A$ rather than a complete adapter on covered vehicles other than model year 2014, and calls for adapter replacement on model year 2014. Transfer sensors only when the applicable replacement procedure requires it. Verify the exact suffix and current part by VIN before ordering. Do not buy a housing, cooler, seal kit, or aluminum conversion until the leak source and installed housing are confirmed.
Owner tips & cautions
TipAsk the shop to show the dye-confirmed source: cap O-ring, adapter bolts, or the adapter-to-block interface. Those paths do not all require the same part.
WarningDo not authorize a complete housing from oil in the valley alone. FCA specifically directs seal-only repair for a confirmed interface leak on covered non-2014 vehicles.
WarningModel year 2014 is an exception in FCA's cited guidance. Confirm the VIN, model year, leak source, and current part suffix before ordering anything.
On the 2011-2023 Jeep Grand Cherokee, wK2 (and 5th-gen WL) Grand Cherokees use hydraulic fluid-filled engine mounts. The mounts commonly fail — the internal fluid leaks out (visible reddish-brown residue on the subframe) and the rubber degrades — producing a pronounced vibration felt through the steering wheel, seat, and floor at idle in gear, plus a clunk on acceleration or gear engagement. It is especially prevalent on the 3.6L Pentastar left/front mount, and forums note 2021-2022 units failing repeatedly; a service bulletin exists for the mounts. It is frequently confused with driveline vibration, so both should be checked together.
Heavy vibration at idle, worse in Drive/Reverse at a stop
Clunk/thump on acceleration or shifting into gear
Reddish-brown fluid residue on the subframe under the engine
Vibration through steering wheel and floor
Engine 'settling' movement felt in cabin
Repeat failures on newer model years
How to Fix
Inspect the engine mounts for fluid weepage and separated rubber; wet/leaking hydraulic mounts should be replaced (replace in pairs on higher-mileage trucks and inspect the transmission mount at the same time). Use OEM Mopar hydraulic mounts rather than solid rubber aftermarket units, which reintroduce vibration. Re-verify idle smoothness in gear after replacement and confirm the driveshaft/mounts aren't jointly contributing.

On the 2011-2013 Jeep Grand Cherokee 3.6L Pentastar V6 (sales code ERB), low engine oil between changes on a 2011-2013 Grand Cherokee 3.6L does not by itself prove that the PCV valve or hose has failed. Chrysler's gasoline-engine diagnostic bulletin requires a formal oil-consumption test first. Only when the vehicle fails that test does the procedure move to checking the complete PCV system for restriction, the correct valve part, and the correct vacuum source; if the PCV system is correct, compression and cylinder leak-down testing follow. The previous card described the PCV system as the primary and most common cause, prescribed an unsupported 30,000-mile replacement interval, recommended a catch can, and attached P052E and P0300 without reviewed FCA support.
Common Symptoms
Engine oil level drops between documented checks
Oil must be added before the scheduled oil change
The vehicle fails Chrysler's formal oil-consumption test
How to Fix
Verify the oil was filled to the correct level and document mileage and oil added under Chrysler's oil-consumption test procedure. If the vehicle passes the test, do not replace PCV parts for this concern. If it fails, inspect the full PCV path for restriction, confirm the installed valve is the correct part for the VIN and engine, and verify the correct intake-vacuum source; repair only a fault found in those checks. If the PCV system is correct, record a cylinder-compression test and perform a leak-down test using the applicable service specifications. Also diagnose any visible external leak separately. Do not order a PCV valve, revised hose, or catch can from oil use alone, and do not treat P052E or P0300 as part of this card without an actual scan and code-specific diagnosis.
Owner tips & cautions
TipRecord the exact oil level, mileage, and quantity added. A repeatable consumption test is more useful than guessing from one low reading.
WarningDo not treat the PCV valve as the default repair. Chrysler's sequence checks it only after a failed oil-consumption test and moves to compression and leak-down testing when PCV is correct.
WarningThe old 30,000-mile PCV interval, catch-can recommendation, P052E/P0300 mapping, and universal valve/hose purchases were removed because the reviewed FCA evidence does not support them for this card.
On the 2011-2022 Jeep Grand Cherokee, the electronic-throttle-control warning lamp and reduced-power or limp mode are protective responses, not a diagnosis that the throttle body has failed. Depending on the stored DTC and application, the factory path may lead to a stuck or contaminated throttle plate, throttle motor or position-sensor response, accelerator-pedal sensors, a five-volt supply fault, damaged wiring or terminals, or a PCM issue. The old card's thermostat shopping claim is not part of the cited ETC diagnostic path, and a throttle body should not be ordered from the warning lamp alone.
One or more throttle, pedal, voltage-supply, or actuator DTCs
How to Fix
Before clearing anything, record every PCM DTC, pending code, freeze-frame value, battery voltage, temperature, and the exact conditions under which reduced power occurred. Diagnose prerequisite five-volt-supply, throttle-position, accelerator-pedal, or other active faults in the order specified by the current factory procedure for that VIN and engine. For a P2111-style fault, inspect the throttle plate for binding or foreign material and run the scan-tool throttle-follower test, then test the motor circuits, connector terminals, and wiring as directed. For a pedal-correlation code such as P2138, follow the accelerator-pedal sensor and circuit procedure instead. Replace and relearn a throttle body only when the applicable test condemns it; do not buy a thermostat as an ETC rule-out part.
Owner tips & cautions
WarningAn ETC lamp does not prove the throttle body failed. Save the codes and freeze-frame data before clearing them or disconnecting the battery.
TipAsk the shop to name the exact DTC and the failed factory test step before approving any throttle-body, pedal, wiring, or PCM part.
On the 2011-2021 Jeep Grand Cherokee, hEMI-equipped Grand Cherokees can develop the characteristic MDS lifter tick. This ticking noise is most noticeable at idle and during light throttle. While often not immediately harmful, it indicates lifter wear from the MDS cylinder deactivation system.
Use quality synthetic oil meeting Chrysler MS-6395 spec. Consider MDS delete kit for permanent solution. Some owners have replaced lifters and camshaft under extended warranty. Regular oil changes help minimize tick progression.
Owner tips & cautions
TipRegular oil changes help minimize tick progression.

On the 2013-2014 Jeep Grand Cherokee 3.6L Pentastar V6 (sales code ERB), built on or before March 12, 2014 (MDH 0312XX), on a small number of 2013-2014 Grand Cherokee 3.6L vehicles built on or before March 12, 2014, the malfunction indicator lamp may illuminate with P0520, Engine Oil Pressure Sensor Circuit. FCA's bulletin directs replacement of the oil-pressure sensor with revised part 05149062AA and clearing the stored DTC. This is a circuit-code service action; it is not evidence that every vehicle has low mechanical oil pressure or that the sensor is leaking. The previous card mixed an alleged upper-pan leak, rear-main-seal misdiagnosis, a sensor leak, oil-filter-housing advice, RTV, lower-pan gasket, oil filter, and five sets of generic searches into one issue.
Scan all modules and record every DTC. Confirm the vehicle is a 2013-2014 WK Grand Cherokee with the 3.6L ERB engine and was built on or before March 12, 2014. Follow normal diagnosis for any other codes first. When P0520 and the bulletin conditions are present, replace the oil-pressure sensor with FCA part 05149062AA, renew the six intake-plenum seals 5184562AC and six intake-manifold seals 5184331AC required by the 3.6L procedure, reassemble to current service specifications, clear the code, and verify it does not return. Do not use this card to diagnose an external oil leak, an oil-pan leak, or a P06DD/P06DE-only condition; FCA says those pump-control codes point first toward the oil-pump solenoid unless a listed pressure-sensor code is also present. Verify all part numbers and supersessions by VIN before ordering.
Owner tips & cautions
WarningP0520 is a sensor-circuit code. Do not describe it as proof of an oil leak or actual low mechanical oil pressure without the required diagnosis.
TipConfirm the March 12, 2014 build cutoff and exact DTC before ordering. The FCA service action is narrower than the old 2011-2021 card.
WarningThe linked sensor is the exact 05149062AA named by FCA. The required intake seals are listed without retailer links until exact product pages and current VIN supersessions are verified.
On the 1994-2004 Jeep Grand Cherokee 4.0L I6 (PowerTech/AMC 242), oil can collect around the 4.0L oil-filter adapter and travel along the block, but the wettest visible point is not always the source. The prior card correctly pointed owners toward the adapter seals yet overstated how often the leak is misdiagnosed and assigned a single Mopar/Crown number across the entire span without catalog proof. ShowMeTheParts does map MAHLE's three application-specific seals and GS33781 kit to the 1994 and 1999-2004 Grand Cherokee 4.0L applications checked in this audit.
Common Symptoms
Fresh engine oil around the oil-filter adapter
Oil tracking along the side or rear of the engine block
Oil spots beneath the engine
Gradual engine-oil level loss
How to Fix
Clean the adapter, filter sealing surface, oil-pressure sender area, valve-cover edge, oil-pan rail, and nearby block, then recheck after a short run; use fluorescent dye if the path is not obvious. Confirm that the oil starts at an adapter seal rather than the filter gasket, sender, valve cover, oil pan, or rear main area. Once the adapter is confirmed, replace all three application-matched seals and inspect the adapter and sealing surfaces for damage. The exact MAHLE GS33781 kit below contains the catalog-matched seal set, but verify the vehicle and 4.0L engine on the product page before ordering. Recheck for leakage and oil level after the repair.
Owner tips & cautions
TipDegrease the area and establish the first wet point before buying parts. Oil from the filter gasket, sender, valve-cover edge, oil-pan rail, or rear of the engine can cross the same area.
WarningThe old card's T60-fastener and adapter-delete advice was not universal enough for this full year span. Follow the service information for the exact adapter installed on the vehicle.
On the 2011-2017 Jeep Grand Cherokee, the Totally Integrated Power Module (TIPM) can fail, causing various electrical issues including fuel pump relay problems (no start), random horn honking, and erratic behavior of lights and accessories.
For fuel pump relay failure: Install an external bypass relay kit ($30-50 DIY) to power fuel pump directly. For complete fix: Replace TIPM unit with remanufactured unit ($400-600) or new OEM ($800-1,200). Some electrical shops can repair/rebuild existing TIPM for $200-400.
Owner tips & cautions
WarningThis is a high-severity issue - ignoring it can lead to costly repairs or safety concerns. Address it promptly.

On the 2012-2014 Jeep Grand Cherokee, certain 2012-2014 Jeep Grand Cherokee vehicles are covered by alternator-diode safety recalls P60 / NHTSA 14V-634 or T36 / NHTSA 17V-435. P60 covers specified 3.6L vehicles with a 160A alternator. T36 covers VIN-included WK vehicles with electro-hydraulic power steering and specified 3.6L or 5.7L, 160A, 180A, or 220A configurations. FCA says thermal or rapid diode failure can stop alternator output, cause a stall with limited warning, or create a resistive short that produces heat, smoke, or an underhood fire. The exact campaign and completion status are VIN-specific.
Common Symptoms
Limited or no warning before alternator output is lost
Battery or charging-system warning
Electrical systems lose power or the engine stalls
Heat, smoke, burning odor, or fire from the alternator area
How to Fix
Check the VIN for open P60 / 14V-634 and T36 / 17V-435 campaigns and schedule an authorized Jeep dealer if either is incomplete. FCA's T36 procedure has the dealer inspect the alternator part-number tag; a listed improved unit needs no further action, while a suspect, illegible, missing, aftermarket, or remanufactured unit is replaced under the campaign with an alternator containing improved diodes. The recall repair is free for an eligible VIN, and the owner notices include a reimbursement path for qualifying prior repairs. Do not use the old retail alternator, battery, starter, charger, or EV-charger links in place of the recall. If the vehicle loses electrical power, stalls, or shows alternator heat, smoke, or fire, stop safely, move occupants away, and arrange towing or emergency assistance as appropriate.
Owner tips & cautions
WarningRecall eligibility is VIN-specific. Check both P60 / 14V-634 and T36 / 17V-435; do not assume a prior generic alternator replacement completed the campaign.
TipFCA's T36 process starts with the alternator tag. The dealer replaces the unit only when the tag/part status calls for it, and an illegible, missing, aftermarket, or remanufactured unit is handled under the campaign procedure for an eligible VIN.

On the 2022-2026 Jeep Grand Cherokee 2.0L Turbo I4 plug-in hybrid (4xe), certain 2022-2026 Jeep Grand Cherokee 4xe vehicles are included in FCA safety recall 68C / NHTSA 25V-741. FCA's amended report lists 91,847 potentially involved Grand Cherokee PHEVs built from July 23, 2021 through November 25, 2025. In rare circumstances, cells in the high-voltage battery pack may have separator damage which, combined with other internal cell interactions, can lead to a vehicle fire while parked or driving. FCA identifies no warning before the condition. The prior card used the wrong recall number and offered a complete traction-battery purchase even though the remedy is a free VIN-specific campaign.
Common Symptoms
FCA identifies no advance warning before the battery condition
Smoke, heat, or fire from the high-voltage battery area
How to Fix
Check the VIN for open recall 68C and contact an authorized Jeep dealer. Until the recall remedy is completed, follow FCA and NHTSA's instruction not to recharge the vehicle and to park it outside, away from structures and other vehicles. FCA's remedy is a software flash followed by high-voltage battery replacement if needed; the amended report also provides an unlimited-years/unlimited-mileage warranty extension for impacted customers who receive defect-related messaging and need a battery. Vehicles previously repaired under superseded recall 95B / 24V-720 still need the new 68C remedy if the VIN is included. If smoke, heat, a burning smell, or fire is observed, move away from the vehicle and call emergency services. Do not buy or install a salvage or retail high-voltage pack in place of the recall.
Owner tips & cautions
WarningFCA identifies no advance warning. Until recall 68C is completed, do not recharge the vehicle and park outside away from structures and other vehicles.
WarningRecall 68C / 25V-741 replaces the prior battery-fire campaign for this population. A vehicle repaired under 95B / 24V-720 may still require the new remedy; verify by VIN.
TipThe dealer performs the software flash and replaces the battery only when the recall analysis indicates it is needed. The full pack is not a self-purchase recommendation.
On the 2005-2007 Jeep Grand Cherokee, on 2005-2007 (WK) Grand Cherokees, wear inside the ignition switch/lock cylinder can allow the key to be jarred out of the RUN position — by a knee, a heavy key ring, or a rough road — which shuts off the engine and can disable power steering, power brake assist, and the airbags while driving. Owners also report the key sticking, being hard to turn, or not returning the fob to a working state. FCA issued Safety Recall P41 (NHTSA campaign 14V-438) covering the affected Grand Cherokees; the remedy replaces the ignition switch and lock cylinder assembly. This is a genuine safety defect (unintended stall / loss of assist) rather than a mere inconvenience.
Key can rotate out of RUN with a bump or heavy key ring
Key sticks or is hard to turn in the ignition
Loss of power steering / brake assist after stall
Warning lights or accessories cutting out
Difficulty restarting after the key backs out
How to Fix
Verify the VIN against Safety Recall P41 / NHTSA 14V-438 at a Jeep dealer — the ignition switch and lock cylinder replacement is performed free of charge under the recall. Out of warranty or for non-recalled sticking-key complaints, replace the ignition switch/lock cylinder assembly and inspect the wiring/connector. Interim mitigation: remove heavy items from the key ring so nothing loads the key downward until the repair is done.
Medium ConfidenceVerified0 reportsReviewed Jul 2026
On the 2011-2014 Jeep Grand Cherokee, grand Cherokees with electro-hydraulic power steering subject the alternator to cyclical electrical loads that cause thermal failure of the internal diodes. The alternator can fail suddenly, stalling the vehicle without warning and, in some cases, short-circuiting and causing an under-hood fire. Multiple NHTSA campaigns cover the 160/180/220-amp units.
Have the applicable recall performed (NHTSA 14V-634 for 160-amp 3.6L units, and 17V-435 for EHPS-equipped 5.7L/3.6L vehicles): dealers inspect and replace the alternator free of charge. Out of warranty, replace the alternator with an updated unit; budget roughly $400-$700 including labor.
On the 2022-2025 Jeep Grand Cherokee 2.0L turbo plug-in hybrid, grand Cherokee 4xe models have generated substantial owner complaints for hybrid system warnings, charging faults, propulsion loss, and no-start conditions tied to the high-voltage battery pack, battery coolant heater, or related control logic. Several recalls and service actions have addressed fire risk, battery pack concerns, and software behavior in 4xe vehicles. Owners commonly describe a check engine light with 'service charging system' or 'service hybrid electric vehicle system' messages, sometimes leaving the vehicle unable to charge or drive normally.
Common Symptoms
service hybrid electric vehicle system message
service charging system message
vehicle will not charge
reduced power or limp mode
check engine light on
no-start condition
How to Fix
Diagnose with a scan tool capable of reading hybrid control modules, then inspect for active recalls, battery pack faults, coolant heater issues, and software updates. Repairs range from module reprogramming and battery coolant heater replacement to high-voltage battery pack replacement depending on the fault path. Because of the high-voltage system and fire-related campaigns, dealer-level diagnosis is strongly recommended.
Owner tips & cautions
TipBefore troubleshooting, check VIN-specific open recalls and software campaigns; many 4xe complaints are tied to updates or battery-related safety actions.
TipOwners recommend documenting charge level, ambient temperature, and whether Level 1 or Level 2 charging was used when faults occur, since intermittent charging issues can be pattern-dependent.
On the 2021-2023 Jeep Grand Cherokee, chrysler recalled 2022-2023 Grand Cherokee, 2021-2023 Grand Cherokee L (plus 2022-2024 Wagoneer/Grand Wagoneer) because the Central Vision Park Assist Module (CVPAM) software can prevent the rearview image from displaying when the vehicle is shifted into reverse — a non-compliance with FMVSS 111 'Rear Visibility' that raises backover-crash risk. A separate small recall covered a handful of units with an improperly connected coaxial camera cable. Owners of 5th-gen WL vehicles continue to report blank/black backup-camera screens and frozen displays tied to radio/module software, with additional camera-related recalls issued through 2024.
Common Symptoms
black or blank screen when shifting to reverse
no backup camera image
frozen rearview camera display
park-assist/camera fault
How to Fix
Have the dealer perform the recall software update to the Central Vision Park Assist Module (and verify the camera coaxial cable connection if applicable) at no charge. If the camera screen is black or frozen, a Uconnect/radio software update or module reset is often the fix. Check VIN recall status via NHTSA before assuming an out-of-warranty repair.
On the 2022-2026 Jeep Grand Cherokee, owners of 2022-2026 Grand Cherokee and Grand Cherokee L (WL) report severe parasitic battery drain: control modules (infotainment/radio, keyless entry, body modules) fail to enter sleep mode after the vehicle is shut off, rapidly draining the 12V battery. Some report a completely dead battery after the vehicle sits just 7-10 days, with repeated jump-starts and premature battery replacements early in the vehicle's life. The condition can disable safety and convenience features and has prompted a class-action investigation. Chrysler has acknowledged related concerns through TSBs addressing excessive module wake cycles and radio/infotainment-related drain.
Have the dealer perform an ignition-off-draw (IOD) parasitic draw test to isolate the offending module, and apply the latest software/TSB updates (e.g., bulletins addressing radio/infotainment module wake cycles). Updating control-module software often reduces the drain. A battery test/replacement may be needed if the original was repeatedly deep-cycled. A battery maintainer helps if the vehicle sits for extended periods.
On the 2014-2018 Jeep Grand Cherokee, uconnect resets or a blank screen, intermittent accessories, a discharged battery, and communication faults may occur together, but they do not establish that the Body Control Module is defective. Radio software or hardware, a weak battery or charging problem, poor power or ground, damaged CAN wiring or terminals, another module that will not sleep, and a true internal module fault can overlap. FCA has a software bulletin for specific early 2014 WK vehicles with RA3/RA4 radios, including radio resets and radio-caused battery drain, but that bulletin is sales-code and build-date specific and does not justify replacing a BCM, Intelligent Battery Sensor, or battery on every 2014-2018 vehicle.
Common Symptoms
Uconnect radio resets, locks up, goes blank, or responds slowly
Intermittent accessory or warning-lamp behavior
Battery is discharged after the vehicle sits
One or more modules store lost-communication faults
How to Fix
Start with a complete vehicle scan and save active, stored, and environmental data before clearing anything. Load-test the battery, verify charging voltage, and repair low-voltage faults first. Inspect the relevant fuses, power feeds, grounds, connectors, and CAN wiring, then measure key-off draw only after the vehicle has completed its normal sleep period and isolate the circuit that remains awake. For radio resets, identify the exact radio sales code and vehicle build date and check the VIN for the applicable FCA software or radio procedure. For a lost-communication fault, determine whether the named module is actually offline, whether multiple modules logged against it, and whether its power, ground, and network circuits pass before condemning it. Replace and VIN-configure a BCM, radio, IBS, or battery only when the component-specific test proves it failed.
Owner tips & cautions
WarningU0140 means communication with the BCM was lost; it does not prove the BCM itself failed. Voltage, power, ground, wiring, network, and reporting-module faults must be separated first.
TipAsk the shop to show the sleep-current measurement, the circuit that stayed awake, and the network scan before authorizing an expensive programmed module.
On the 1999-2004 Jeep Grand Cherokee, the WJ PCM (engine computer) can develop internal faults — often heat/temperature-related micro-cracks or solder failures — that cause intermittent stalling, hard-to-diagnose no-starts and driveability problems that come and go with ambient temperature. A well-known WJ case: a 2000 4.7L stalled only when outside air exceeded ~60F; a rebuilt/replaced PCM cured it after many other parts were replaced in vain.
Intermittent stalling, often correlated with heat/warm weather
Crank but no-start that comes and goes
Multiple unrelated sensor codes
Driveability that improves when cold
Repairs of individual sensors don't resolve it
How to Fix
Diagnose by elimination after CKP, fuel pump, and grounds are ruled out. Options: send the PCM for bench repair (specialists like Circuit Board Medics), or install a remanufactured PCM programmed to the vehicle's VIN and SKIM/immobilizer. Any replacement PCM must be VIN-programmed to run. Inspect PCM connectors/pins for corrosion first.

On the 1999-2004 Jeep Grand Cherokee, the WJ-generation Grand Cherokee instrument cluster is a well-known weak point. Owners report gauges that suddenly stop working, read erratically, or dim so far they're unreadable even with the dash brightness turned all the way up. Causes range from loose/corroded cluster connectors and cold-solder joints to electroluminescent backlight aging and Body Control Module (TIPM) interaction. The condition is often intermittent at first (a firm tap on the dash or an odometer-reset press temporarily restores the gauges) before becoming permanent.
Speedometer/tach/gauges suddenly quit or read erratically
Gauge and odometer backlight too dim to read
Intermittent operation restored by tapping dash or pressing odometer reset
Multiple gauges failing together
How to Fix
Remove the cluster and reseat/clean the connectors with contact cleaner; resecure loose plugs. Repair cold-solder joints on the cluster circuit board or replace the cluster (2002-2004 electroluminescent clusters can be retrofitted into 1999-2001 cars). Verify BCM/grounds if multiple unrelated gauges drop together. Re-check connector retention after reinstall.

On the 2014-2021 Jeep Grand Cherokee, stop-Start-equipped WK2 Grand Cherokees use a small secondary (auxiliary) AGM battery in addition to the main battery to power electronics during the engine auto-restart. This auxiliary battery (and sometimes the main AGM) fails relatively early, producing 'Stop/Start not available - battery charging' or 'Stop/Start Not Ready' messages and disabling the auto start-stop feature. Installing a non-AGM wet-cell battery causes premature failure because it cannot handle the cycling load. The Intelligent Battery Sensor (IBS) can also need a relearn after any battery replacement, during which ESS is temporarily inhibited.
'Stop/Start not available - battery charging' message
'Stop/Start Not Ready' / feature disabled
Intermittent ESS operation that quits after a few stops
Possible slow crank or electrical glitches
How to Fix
Test both the main and auxiliary batteries; replace the failed unit with the correct AGM specification (the auxiliary is a small dedicated battery, often near the air-box/fender). After replacement allow the IBS relearn to complete (several drive cycles). Never substitute a standard flooded battery. Verify charging-system output if messages persist.

On the 2011-2021 Jeep Grand Cherokee, grand Cherokees equipped with factory HID/xenon projector headlights are commonly reported for dim or color-shifted low beams as the bulbs age, single-side bulb or ballast failures, and internal lens condensation. Per Chrysler service guidance, some condensation inside vented HID housings is considered normal and should clear as the bulbs heat up; however, persistent moisture from a failed lens-to-housing seal can corrode reflective surfaces and shorten bulb life. Older assemblies also haze/yellow, further reducing output.
For dim/aged output replace the HID bulbs (and ballast if a bulb fails to strike); match bulbs in pairs for even color. For mechanical high/low projector faults inspect the projector shutter solenoid. If condensation does not clear after running the lights, replace the headlight assembly due to a failed seal. Restore hazed lenses or replace assemblies as needed.

On the 2022-2024 Jeep Grand Cherokee, owners of WL-generation Grand Cherokee models have reported persistent airbag warning lights and restraint system messages tied to seat wiring/connectors, especially around second-row or seat-mounted side airbag circuits. FCA also issued safety actions/TSB guidance on certain restraint-related faults in this generation. The practical problem is that the SRS may be disabled or operate improperly until the connector, harness, or module issue is corrected.
Common Symptoms
airbag warning light on
service airbag system message
restraint system warning chime
intermittent warning after moving seats
warning returns after clearing codes
How to Fix
Scan the Occupant Restraint Controller for stored codes, then inspect under-seat connectors, terminal tension, harness routing, and any signs of pin drag or intermittent contact. Repairs typically involve connector replacement, terminal repair, harness retention updates, or module/software updates depending on the exact fault. Clearing the light without fixing the root cause usually results in repeat warnings.
Owner tips & cautions
TipOwners often suggest documenting exactly when the warning appears, especially after seat movement or folding the second row, to help isolate an intermittent connector issue.
TipAvoid probing SRS connectors with generic test lights; use proper scan diagnostics and battery disconnect procedures before any seat harness inspection.
On the 2014-2015 Jeep Grand Cherokee, the 2014-2015 Grand Cherokee uses a ZF monostable electronic 'E-shift' gear selector that always returns to a center position regardless of selected gear, giving poor tactile/visual feedback. NHTSA tied it to over 300 rollaway incidents and 117 crashes after drivers believed they had shifted into Park but had not. FCA recalled 811,586 vehicles (including 2012-2014 Charger/300 with the same shifter) and added Auto Park software.
Vehicle rolls away after the driver believes it is in Park
Difficulty telling which gear is selected from the shifter position
Shifter returns to center after each gear change
Engine left running after exit because shift to Park was not registered
How to Fix
Have the recall (NHTSA 16V-240) performed: dealers install software that automatically applies Park when the driver's door opens with the engine running and the seatbelt unbuckled. The shifter was redesigned to a conventional pattern from MY2016. Until the fix, always confirm the 'P' indicator and set the parking brake before exiting.
On the 1999-2010 Jeep Grand Cherokee, the clockspring is a plausible shared point when a Grand Cherokee has an airbag warning together with a failed horn, cruise control, or steering-wheel buttons. Factory wiring confirms that those circuits pass through the clockspring/steering-control assembly. That symptom combination does not prove the clockspring has failed, however: an SRS indicator means the restraint controller detected a monitored fault, and horn switches, relays, wiring, connectors, steering-control electronics, airbag circuits, and controller faults require separate diagnosis. The old card also combined 1999-2004 WJ and 2005-2010 WK part numbers without complete catalog or configuration proof.
Common Symptoms
Airbag or SRS warning indicator
Horn inoperative from the steering wheel
Cruise-control or steering-wheel buttons inoperative
Fault changes with steering-wheel position
How to Fix
Treat an illuminated airbag indicator as a safety fault and have the SRS scanned with a restraint-capable tool. Record the exact active and stored DTCs, follow the model-year circuit tree, and test the horn and steering-wheel functions independently before condemning the clockspring. If circuit testing confirms the clockspring/steering-control assembly, select the replacement by VIN, model year, steering-wheel controls, steering-angle-sensor configuration, and current Mopar supersession. The assembly must be centered and the steering wheel kept in the correct position. SRS service can cause accidental deployment: follow the factory disable procedure, isolate the negative battery cable, wait the specified discharge time, and use trained service if you are not qualified. After repair, clear and recheck SRS DTCs and verify every wheel function.
Owner tips & cautions
WarningDo not probe airbag inflator circuits with an ordinary test light or meter and do not rotate an uncentered replacement clockspring. Follow the model-year SRS procedure or use a qualified technician.
TipSave the exact SRS DTCs before clearing them. The lamp plus a dead horn is a useful clue, but the DTC and circuit test determine whether the clockspring is actually open.
On the 1994-2004 Jeep Grand Cherokee, for the ZJ (1993-1998) and WJ (1999-2004) Grand Cherokee, Chrysler mounted the plastic fuel tank behind the rear axle with little rear-structure protection. NHTSA and the Center for Auto Safety documented that these vehicles were far more likely to suffer a fatal post-crash fire in rear impacts. Recall 13V-252 (issued June 19, 2013) covered ~1.56 million 1993-2004 Grand Cherokee and 2002-2007 Liberty vehicles. This is one of the most-searched safety topics for older Grand Cherokees.
Common Symptoms
Fuel tank located behind the rear axle with minimal shielding
Elevated fire risk in rear-end collisions
Recall remedy (rear reinforcement hitch) not yet installed
How to Fix
Recall remedy (Campaign N45, free at Jeep dealers) installs a factory Mopar trailer-hitch/rear-structure reinforcement that shields the tank in low-to-moderate rear impacts. Owners should verify the recall was completed via VIN at NHTSA/the dealer; if not, have the hitch installed. Note critics consider the fix only a partial mitigation — the tank position is unchanged.

On the 2022-2023 Jeep Grand Cherokee, a documented recall affected certain 2022-2023 Grand Cherokee and Grand Cherokee L vehicles because steering column intermediate shaft hardware may not have been properly secured. Owners and regulators flagged the possibility of steering separation or loss of steering control, sometimes preceded by looseness, clunks, or abnormal steering feel. Even when symptoms are subtle, this is a serious defect because it directly affects directional control.
Common Symptoms
steering wheel play
clunk when turning
loose or vague steering feel
steering wheel off-center
abnormal steering feedback
How to Fix
Inspect the intermediate shaft connection, pinch bolt torque, and steering column coupling per FCA recall procedure. Dealers replace or correctly secure the shaft hardware and verify steering operation afterward. Any steering play, clunk, or off-center wheel should be checked immediately and the vehicle should not be used until repaired.
Owner tips & cautions
TipOwners commonly recommend checking for any steering clunk or free play during a test drive after recall completion rather than assuming the repair was done correctly.
TipIf the wheel is no longer centered after repair, request a steering angle calibration and alignment check.
On the 2023-2024 Jeep Grand Cherokee, fCA US recalled 121,398 model-year 2023-2024 Grand Cherokee (78,157 units) and Grand Cherokee L (43,241 units) vehicles because the second-row head restraints contain an internal locking mechanism with an interference condition. When the seatback is folded down, the mechanism can stick, leaving the headrest folded forward and unable to lock in the upright position. A head restraint that doesn't lock falls below the federally required minimum height (about 29.5 in) and increases the risk of occupant injury (whiplash/head injury) in a crash, violating FMVSS 202a.
Common Symptoms
second-row headrest will not lock upright
headrest stuck folded forward after folding seat
head restraint sits below required height
How to Fix
Take the vehicle to a Jeep dealer; they will inspect and, if necessary, replace both second-row head restraints at no charge. Verify whether the second-row headrests fully lock upright after folding the seats; if one stays folded forward, the part needs replacement. Check VIN recall status via NHTSA or Mopar owner site.
On the 2004 Jeep Grand Cherokee 4.7L V8 or 4.7L High Output V8 with 545RFE automatic (sales code DGQ), daimlerChrysler TSB 08-016-05 describes an internal TCM circuit fault that may cause an intermittent low-line-pressure or gear-ratio DTC and limp-in on a specific 2004 WJ/WG Grand Cherokee population. The vehicle must have the 545RFE (sales code DGQ), a 4.7L or 4.7L High Output engine, and fall within the bulletin's April 7, 2004 through February 27, 2005 vehicle build range. Suspect TCMs have date codes 0984 through 0405. This is not a universal 1999-2010 transmission-overheating/shudder diagnosis, and it does not justify buying filters, fluid, a cooler, valve-body kits, or a solenoid pack from the symptom alone.
Malfunction indicator lamp with a low-line-pressure or gear-ratio fault
P0868 line-pressure-low fault
P0731-P0736 or P1736 gear-ratio fault
How to Fix
Confirm the VIN build record, 545RFE sales code DGQ, stored transmission DTCs, and TCM event data. Read digits three through six of the TCM barcode; TSB 08-016-05 identifies 0984 through 0405 as the suspect controller build range. If the vehicle or controller date is outside scope, the bulletin does not apply and the transmission complaint needs its normal diagnostic path. For an in-scope vehicle, use the bulletin's P0868/gear-ratio decision path and compare desired, scan-reported actual, and mechanically measured line pressure with correct fluid level and temperature. Inspect wiring, connectors, cooler lines, leaks, and engine driveability first. The repair may involve the TCM and, when low pressure was present, inspection for clutch-disc damage; it is not a universal retail-parts fix. No commerce links are shown until those findings identify the required repair.
Owner tips & cautions
WarningDo not apply this TSB to every 45RFE/545RFE complaint. It requires a 2004 WJ/WG, 4.7L/4.7L H.O., sales code DGQ, the bulletin's vehicle build range, a listed DTC, and a suspect TCM date code.
TipPreserve the TCM event data before clearing codes. The bulletin uses that data and the controller barcode date to separate a controller fault from actual low pressure and clutch damage.
WarningA filter kit, ATF, cooler, Sonnax valve, separator plate, or solenoid pack is not a complete answer to this card. The old links represented different failure paths and have been removed.
On the 2005-2013 Jeep Grand Cherokee, the Mercedes-derived W5A580 (NAG1) 5-speed automatic used in WK and early WK2 Grand Cherokees is mechanically strong but suffers well-documented electronic and fluid-related failures. Faulty conductor-plate speed sensors and shift-pressure solenoids drop the transmission into limp mode (stuck in a single gear). Contaminated or degraded fluid (including water intrusion past the dipstick/fill-tube seal) causes torque-converter-clutch shudder, harsh or delayed shifts, and a knock on coasting downshifts. The 13-pin connector adapter can also leak, wicking fluid into the harness by capillary action.
Scan for transmission codes; for limp mode inspect/replace the conductor plate (with integrated speed sensors) and any failed shift solenoid, and replace the 13-pin connector adapter/seal if leaking. Perform a full fluid-and-filter service with the correct ATF (MB 236.x / Mopar spec). Address water intrusion at the fill tube. Severe internal damage from prolonged shudder may require a rebuild.

On the 1993-2004 Jeep Grand Cherokee, visible corrosion at an outer rocker, rear wheel arch, or floor can range from a limited outer-skin repair to extensive loss of the inner rocker, pinch weld, floor reinforcement, suspension or seat-belt mounting areas, or adjacent unibody structure. A replacement outer panel does not prove the vehicle is structurally repairable and should not be used to hide unsupported metal. The prior card's broad prevalence, price, and do-it-yourself framing did not distinguish cosmetic sheet metal from load-carrying corrosion.
Common Symptoms
Bubbling paint, perforation, or flaking metal at a rocker or rear wheel arch
Soft or deformed pinch weld or jacking area
Floor corrosion, water intrusion, or separated seams
Corrosion extending behind an outer panel into inner structure
How to Fix
Before ordering a panel, have a qualified collision/body technician remove or move the necessary trim and map the corrosion from sound metal to sound metal on both sides of the area. Inspect the inner rocker, pinch weld and jacking areas, floor and reinforcements, nearby mounts, rails, seams, and drain paths. If load-carrying metal or safety-system mounting structure is compromised, stop using the affected lift point and obtain a documented structural repair or retirement decision; an outer cover panel is not the repair. If the damage is limited and the surrounding structure is sound, select the exact ZJ or WJ generation and left or right outer rocker, follow the factory body-repair weld/sectioning guidance, and restore seams, sealers, cavities, coatings, and drainage after welding. Wheel-arch and floor sections should be selected from the body shop's measured cut plan rather than a model-wide shopping list.
Owner tips & cautions
WarningDo not place a jack or stand on a perforated or collapsing pinch weld. Have the lift points and adjacent structure assessed before the vehicle is raised there again.
WarningAn outer rocker panel is a repair skin, not proof that hidden inner structure is sound. Cutting and welding should follow a measured body-repair plan with fire protection and restored corrosion protection.
On the 2000-2004 Jeep Grand Cherokee, wJ Grand Cherokees are well known for failing power window regulators, often due to broken plastic guides, cable failures, or regulator track issues. Owners frequently report a loud pop followed by the window dropping into the door or becoming crooked and inoperative. Failures are common on multiple doors over the life of the vehicle.
Common Symptoms
Window falls into door
Crunching or popping noise in door
Window moves crooked
Window motor runs but glass does not move
Intermittent window operation
How to Fix
Remove the door panel and inspect the regulator assembly, cable, and glass mounts. The standard repair is replacement of the complete regulator, often with an updated aftermarket metal-reinforced unit; inspect the switch and motor only if the regulator mechanism is intact. Replacing vapor barrier adhesive and checking door drains helps prevent moisture-related repeat issues.
Owner tips & cautions
TipOwners strongly prefer metal-backed or upgraded aftermarket regulators over early plastic-heavy designs.
TipHave spare door-panel clips on hand before disassembly because the originals often break during removal.
On the 2022-2025 Jeep Grand Cherokee, owners have reported the hands-free/power liftgate on the WL Grand Cherokee opening unexpectedly, reversing while closing, beeping without completing the cycle, or failing to latch. Reports point to latch alignment issues, pinch-sensor calibration problems, weak struts, or software/body control faults. While not usually catastrophic, it is a recurring nuisance and can create injury risk or battery drain if the gate remains ajar.
Common Symptoms
liftgate beeps but does not close
liftgate reverses while closing
rear hatch says open when shut
hands-free liftgate works intermittently
battery drain from hatch not fully latched
How to Fix
Check for stored body/liftgate module faults, verify latch alignment and striker position, inspect pinch sensors and wiring in the hinge area, and test strut force. Dealers often address this with software updates, latch adjustment, sensor replacement, or liftgate module relearn procedures. If the gate bounces back or will not latch, avoid forcing it repeatedly because that can damage the cinch motor.
Owner tips & cautions
TipClean the latch and striker area and verify no cargo mat or weatherstrip interference before assuming a module failure.
TipOwners recommend performing the power liftgate height/memory relearn after battery replacement or low-voltage events.
On the 2011-2021 Jeep Grand Cherokee, on WK2 Grand Cherokees the sunroof/panoramic roof drain tubes kink, slip off, or clog with debris and slime at the lower reducer fittings. When the drains back up, water overflows the roof track and runs down the A-pillars into the headliner and floor, soaking carpet and risking mold and electrical module corrosion. The lower hose hidden near the driver kick panel is a frequent partial-clog point.
Water dripping from the headliner or A-pillars after rain or a car wash
Wet front or rear floor carpet
Musty / mildew smell inside the cabin
Water pooling in footwells
Fogged windows or intermittent electrical faults from moisture
How to Fix
Clear the front and rear drain tubes with low-pressure compressed air or a flexible line (avoid high pressure, which can pop the tube off the roof). Re-seat or replace cracked/disconnected tubes; some require partial headliner removal. Dry the carpet/underlayment fully to prevent mold and protect floor electronics.
On the 2011-2021 Jeep Grand Cherokee, water found in a WK2 Grand Cherokee cargo well, under the cargo floor, or near a rear pillar is a symptom, not proof that one grommet, weatherstrip, lamp gasket, antenna seal, or roof seam has failed. The factory water-leak procedure warns that water can travel through body cavities and appear far from the true entry point. The old card's shopping list could therefore send an owner to four unrelated products before the leak location was established.
Common Symptoms
Standing water or dampness in the rear cargo area
Wet cargo carpet or insulation after rain or washing
Water track near a rear pillar, liftgate opening, or cargo trim
Musty odor or interior condensation
How to Fix
Dry the accessible area enough to see a new water track, protect affected electrical connectors and modules, and reproduce the conditions under which the leak occurs. Follow the factory water-leak procedure: visually inspect plugs, drains, alignment, seams, seals, and grommets; test one region at a time with an appropriate low-pressure stream or fan spray; remove trim only as needed for safe visual access; and trace the highest fresh water track to its actual entry point. Repair, reseat, or replace only the confirmed failed seal, seam, fastener, drain, weatherstrip, glass bond, lamp seal, or wiring pass-through using the current factory procedure and specified material. Dry wet insulation, inspect exposed terminals for corrosion, and repeat the water test before closing the trim. Do not smear generic RTV across several unconfirmed paths.
Owner tips & cautions
WarningThe puddle location may not be the entry location. Do not buy a grommet, weatherstrip, sealant, or lamp seal until a controlled water test identifies the source.
TipPhotograph the first fresh water track during the test and retest after the repair before reinstalling all wet trim and insulation.

On the 2021-2023 Jeep Grand Cherokee, fCA TSB 23-102-23 covers a 2021-2023 WL Grand Cherokee built on or before February 6, 2023 and equipped with the dual-pane panoramic sunroof, sales code GWJ, when the wind deflector becomes trapped in the sunroof panel and causes a leak. The bulletin's repair is the updated dual-pane wind deflector 68518680AC. It does not establish clogged drains as a second automatic cause, and the old card's 06513746AA fastener belongs to a separate WK/WD rattle bulletin rather than this WL leak repair.
Common Symptoms
Dual-pane panoramic sunroof leaks
Wind deflector is trapped in the sunroof panel
Water appears at the headliner during or after rain or washing
How to Fix
Confirm the vehicle is a WL Grand Cherokee, its build date is on or before February 6, 2023, it has sales code GWJ, and the observed leak matches the trapped-deflector condition in TSB 23-102-23. If it does, replace the dual-pane wind deflector with 68518680AC following the current Service Library removal and installation procedure, then operate the roof and repeat a controlled water test. If the leak does not match this bulletin or remains afterward, continue the full factory water-leak diagnosis for drains, seals, glass, seams, and other possible paths instead of ordering unrelated fasteners or additional parts.
Owner tips & cautions
WarningThis part is not a universal sunroof-leak fix. Confirm the WL platform, build cutoff, GWJ sales code, and trapped-deflector condition first.
TipAfter replacement, cycle the roof and repeat the same controlled water test before the headliner and trim are fully closed.
On the 2014-2020 Jeep Grand Cherokee 3.0L EcoDiesel V6 (sales codes EXF and EXN), certain 2014-2020 Jeep Grand Cherokee (WK) vehicles with the 3.0L diesel engine are included in safety recall Z46 / NHTSA 22V-406. The high-pressure fuel pump can fail prematurely and introduce internal debris into the fuel system, causing fuel starvation. FCA says occupants may notice a malfunction indicator lamp, a fuel leak, abnormal engine noise, or a change in drive quality; fuel starvation can cause an unexpected loss of motive power and increase crash risk. Recall inclusion is VIN-specific. The prior card incorrectly included 2021-2023 vehicles and treated an old pump number plus a retail injector set and filters as a universal repair.
Common Symptoms
Unexpected loss of motive power or stalling
Malfunction indicator lamp
Fuel leak
Abnormal engine noise
Change in drive quality or a non-running condition
How to Fix
Check the VIN for open recall Z46 and schedule the free repair with an authorized Jeep dealer. FCA's procedure is condition-dependent: a vehicle delivered in good running condition receives the campaign HPFP and associated non-contaminated-system service, while a non-running vehicle is diagnosed for pump failure and, when contamination is confirmed, receives the pump, in-tank modules, filters, injectors, rails, high-pressure tubes, fuel-system cleaning, and other campaign items specified for that vehicle. If the vehicle stalls, loses power, leaks fuel, or will not restart, move it to a safe location, shut it off, and arrange a tow rather than continuing to run the engine. Do not buy a retail CP4 pump, injector set, or filter bundle before VIN eligibility and contamination status are established.
Owner tips & cautions
WarningRecall eligibility is VIN-specific. Do not assume every 2014-2020 EcoDiesel is included, and do not extend this card to 2021-2023 vehicles.
WarningDo not order the old 68211269AA pump or a universal injector/filter bundle as the recall fix. FCA's dealer kits and component scope change depending on whether pump failure and contamination are present.
On the 2011-2021 Jeep Grand Cherokee 3.6L Pentastar V6, on the WK2 Jeep Grand Cherokee with the 3.6L Pentastar V6, P0171 (and frequently P0174 alongside it) is most commonly triggered by unmetered air entering the engine through a deteriorated intake manifold gasket or a cracked/warped plastic intake manifold. The Pentastar's rubber-and-plastic gaskets become brittle from years of heat cycling and crack, letting in extra air so the upstream O2 sensors report a persistent lean condition. A closely related contributor is the notorious oil filter housing/oil cooler adapter in the engine valley (under the intake manifold) cracking, which is usually addressed at the same time since the intake has to come off. Some early cases are resolved with a PCM software update before parts are replaced.
Smoke-test the intake to confirm the vacuum leak, then replace the intake manifold gasket set (and the plastic intake manifold itself if cracked/warped). Because access requires removing the intake, shops commonly replace the leak-prone oil filter housing at the same time. Check for any available PCM software update first, and verify fuel trims return to normal after the repair.
On the 1999-2004 Jeep Grand Cherokee, the combined in-tank fuel pump / level-sender module on the WJ Grand Cherokee wears out with age: the pump loses pressure (needs ~49-58 psi) causing crank-no-start or hot stalling, while the integrated sending-unit float/resistor card fails causing erratic or stuck fuel-gauge readings. Both a no-start and a jumpy fuel gauge are heavily searched WJ complaints and often the same module.
Fuel-pressure test before replacing. Replace the complete in-tank fuel pump module assembly (Mopar module by application, or quality aftermarket Airtex/Spectra/Delphi for 1999-2004 WJ) rather than just the pump. If the gauge stays erratic after replacement, check the tank-to-cluster wiring/grounds and the instrument cluster gauge circuit. Avoid bending the float arm on install.
Medium ConfidenceVerified0 reportsReviewed Jul 2026
On the 2011-2021 Jeep Grand Cherokee, the WK2 uses a saddle-style fuel tank with two fuel-level senders (one per lobe). The sender floats/rheostats stick or wear, and the PCM flags a sender that no longer tracks fuel consumption, setting P2068 (or related P0461/P0463) and a 'Service Fuel Level Sensor' message. Symptoms include a gauge stuck on Full or Empty, wildly bouncing readings, and an inaccurate Distance-to-Empty. It usually doesn't affect running but can strand an owner who trusts a stuck-full gauge, and it commonly requires dropping the tank to access the sender/module.
Scan for P2068/P0461/P0463 and confirm which sender is faulty. Inspect the sender for a stuck float and check connector/wiring; some intermittent stuck floats free up, but a failed sender requires replacement of the affected fuel-level sensor/sender module (often the in-tank pump/sender assembly), which typically means lowering the fuel tank. Recalibrate/verify gauge sweep after repair.

On the 2020-2022 Jeep Grand Cherokee, fCA TSB 14-005-23 covers a 2020-2022 WK Grand Cherokee that is hard to fill because the fuel nozzle shuts off prematurely. The bulletin identifies the fuel tank filler tube as the repair cause after the other factory hard-to-fill and capless-filler diagnostics have been completed. It does not support the old card's blanket 2011-2021 scope, a universal failed flapper housing, or an automatic connection to EVAP codes. Part selection is engine-sales-code and model-year specific.
Common Symptoms
Fuel tank is hard to fill
Fuel nozzle shuts off prematurely during refueling
How to Fix
Confirm the vehicle is a WK Grand Cherokee within the bulletin's year range, reproduce the premature-shutoff symptom with an appropriate nozzle, and complete the current Service Library hard-to-fill and capless-filler diagnostic procedure first. If the vehicle enters TSB 14-005-23, replace the fuel tank filler tube that matches the VIN, model year, and engine sales code: 68377769AE for 2020-2022 ERC or 2020-2021 EZH, and 68250911AN for 2020-2021 ESG or ESD. Verify the current Mopar supersession by VIN before ordering. Do not buy a flapper housing, tube, or EVAP part merely because the nozzle clicked off once.
Owner tips & cautions
WarningDo not order by the symptom alone. FCA requires the other hard-to-fill diagnostics first, and the correct tube changes with engine sales code and model year.
TipHave the seller or installer verify the VIN, engine sales code, and current Mopar supersession before the order is placed.
On the 2022-2024 Jeep Grand Cherokee, multiple 2022-2024 Grand Cherokee and Grand Cherokee L vehicles were recalled for rear coil springs that may not have been installed correctly, allowing the spring to detach from its upper mount. Owners reported a loud bang from the rear, sudden sagging ride height, and in some cases tire contact with the wheel well. This is a real safety issue because it can affect handling and can damage the tire, increasing crash risk.
Common Symptoms
loud bang from rear suspension
rear of vehicle sitting low on one side
clunking over bumps
tire rubbing noise from rear wheel well
unstable handling
How to Fix
Inspect rear ride height, spring seating, upper isolators, and any signs of spring displacement or tire rub. Vehicles covered by the recall receive inspection and replacement of the rear coil spring assemblies as needed, along with related hardware if damaged. If symptoms appear before recall service, the vehicle should not be driven until the rear suspension is checked.
Owner tips & cautions
TipIf the rear suddenly drops or you hear a bang, inspect for spring displacement and tire rub immediately; many owners recommend towing rather than driving to the dealer.
TipAfter recall repair, ask the dealer for an alignment check if the vehicle was driven while sagging or rubbing.
On the 2011-2021 Jeep Grand Cherokee, quadra-Lift is a closed, electronically controlled air-suspension system, so a Service Air Suspension message, a low corner, or a denied height change does not identify one universal failed part. The factory diagnostic path covers electrical and communication faults, fuses and voltage, pinched or damaged lines, leaking springs, disconnected sensor linkages, water or blockage in the compressor intake, air-mass loss, valve/compressor faults, software, and the Air Suspension Control Module. The prior card also incorrectly treated SRT and Trackhawk as automatic Quadra-Lift applications; applicability should be established by sales code SER or the vehicle build sheet.
Common Symptoms
Service Air Suspension message
One corner or one axle sits low
Ride-height change is slow, denied, or inoperative
Quadra-Lift height indicators flash or normal leveling is disabled
How to Fix
Confirm the vehicle is equipped with Quadra-Lift sales code SER, record the exact ASCM DTCs and environmental data, and check VIN/build-date-specific FCA bulletins before ordering hardware. Follow the factory sequence: repair voltage or communication faults first; inspect fuses, air lines, springs, height-sensor linkages, compressor intake/filter, and visible plumbing; then use a capable scan tool to run the Air Mass and Air Ride Height routines and follow the DTC-specific tree. On 2011-2012 vehicles built before May 1, 2012, U0415-00 or C159E-15 with a Service Air Suspension message may be addressed by FCA TSB 08-034-12's ASCM software update. Replace only the component proven failed. A completely depleted system requires the specified refill equipment, scan-tool procedure, and purity-class-5 nitrogen; do not fill it with ordinary shop air or shotgun-replace springs, sensors, and the compressor.
Owner tips & cautions
WarningDo not replace a compressor because the vehicle sits low. A leaking spring or line, sensor/linkage fault, intake restriction, valve fault, low system air mass, or software condition can create overlapping symptoms and can overwork a replacement compressor.
TipAsk the shop to record the ASCM DTCs, air-mass result, ride-height routine result, and verified leak location. Those findings should select the part, not a generic model-level shopping list.

On the 2011-2021 Jeep Grand Cherokee, front wheel hub/bearing assemblies are a recurring wear failure on the WK2 Grand Cherokee, producing a humming, whining, or growling noise that rises with road speed (commonly noticeable from about 35-50 mph) and often changes pitch when the vehicle is loaded or steered left/right. The integrated hub/bearing units wear relatively early, and owners frequently report needing replacement on one or both front corners. Left unaddressed the bearing can develop play and eventually trigger ABS/traction warnings or, in severe cases, lead to hub damage.
Humming/whining/growling that increases with speed
Noise changes pitch when turning left or right
Vibration felt through floor/steering at highway speed
Possible ABS or traction-control light if bearing develops play
How to Fix
Confirm the failing corner by listening for the speed-dependent hum and checking for bearing play; the noise typically worsens when turning toward the good side. Replace the affected front hub/bearing assembly (sold as a complete unit). Replacing in pairs is common when both have similar mileage. Verify ABS sensor function after replacement.

On the 2011-2021 Jeep Grand Cherokee, a WK2 front-end clunk over bumps, during braking, or while steering can come from more than the sway-bar links or lower control arms named in the old card. The source can vary with loading and may involve a stabilizer link or bushing, control-arm bushing, ball joint, tie-rod end, shock or upper mount, wheel bearing, loose fastener, brake hardware, or another nearby component. Standard and high-performance suspension packages also use different side-specific parts. Ordering four components from the noise alone risks replacing good parts while leaving a safety-relevant loose joint in service.
Common Symptoms
Clunk or knock from the front over bumps
Noise during braking, acceleration, or steering load changes
Possible looseness, uneven tire wear, or steering change if a joint or bushing is worn
How to Fix
Record when the noise occurs and reproduce it safely on a controlled road test. With the vehicle supported according to the factory procedure, inspect wheel and tire security, brake hardware, steering linkage, stabilizer links and bushings, control-arm bushings, upper and lower ball joints, shocks and mounts, wheel bearings, subframe attachment, and nearby shields or loose hardware. Check joints and bushings in the loaded and unloaded positions specified by the service manual, and use chassis ears or controlled isolation when visual play is not obvious. If steering looseness, wheel movement, instability, or a damaged joint is present, stop driving until repaired. Replace only the confirmed failed component using the VIN, side, suspension sales code, and current supersession; torque at the specified ride-height condition and perform an alignment when the repair procedure requires it.
Owner tips & cautions
WarningDo not assume a sway-bar link or control arm from the sound alone. Steering looseness, wheel movement, or a damaged ball joint requires immediate inspection before more driving.
TipAsk the shop to identify the exact failed joint or bushing, side, and suspension sales code and to show the measured play or isolated noise before parts are ordered.
On the 1999-2004 Jeep Grand Cherokee, on the WJ the automatic-transmission fluid cooler is integrated inside the radiator end tank. As the radiator ages the internal cooler barrier fails, allowing engine coolant and ATF to intermix under pressure. The result is a pink/tan 'strawberry milkshake' in both the transmission and cooling system. Coolant (ethylene glycol) in the transmission destroys clutch material and can ruin the 42RE/45RFE if not caught quickly.
Stop driving once contamination is found. Replace the radiator (OEM Mopar radiator by application, or aftermarket CSF/Spectra/Koyorad for 1999-2004 WJ) and thoroughly flush the cooling system. Flush/replace ATF and the transmission filter multiple times; badly contaminated transmissions need a rebuild. Many owners add an external auxiliary trans cooler and bypass the in-radiator cooler to prevent recurrence.

On the 2011-2021 Jeep Grand Cherokee 3.6L Pentastar V6, the integrated plastic-housing thermostat on the 3.6L Pentastar commonly fails stuck open or opens too early, so the engine never fully reaches operating temperature. The ECM sets P0128 (coolant temp below thermostat regulating temperature), and the driver gets weak cabin heat, sluggish warm-up, lower fuel economy, and increased oil contamination. It is one of the most frequently searched check-engine complaints on these engines and is an inexpensive, DIY-friendly fix.
Replace the thermostat (integrated into the Mopar thermostat housing, e.g. 5184651AH-family for 3.6L) using an OEM-grade unit, then properly bleed all air from the cooling system via the bleeder. Verify the coolant temperature sensor and confirm correct coolant level before condemning the thermostat. Clear P0128 and confirm the engine reaches full temp over a few drive cycles.

On the 2021-2024 Jeep Grand Cherokee, on the new WL-generation Grand Cherokee and Grand Cherokee L, two assembly defects can cause loss of steering control. Upper control arm (UCA) pinch bolts damaged during assembly can break and let the UCA separate from the steering knuckle, dropping the wheel outboard. Separately, an incorrectly assembled steering column intermediate shaft can disconnect from the U-joint. Combined recalls cover well over 400,000 vehicles.
Have the open recalls performed: NHTSA 23V-352 replaces the steering column intermediate shaft / U-joint assembly, and 24V-131 (with related campaigns) inspects and replaces the upper control arm pinch bolts free of charge. Address any steering play or clunking immediately rather than waiting.
On the 2008 Jeep Grand Cherokee 4.7L V8, on a 2008 Jeep Grand Cherokee 4WD with the 4.7L V8, clicking, grinding with visible CV grease, a load-related thump or vibration, and front-axle whine or growl are not one failure and do not identify one repair part. A torn CV boot and contaminated joint, an outer CV joint, drivetrain mount or hardware movement, axle or differential bearings, and internal front-axle gear wear require different repairs. The previous card incorrectly described a common 2005-2010 failure with mileage and cost predictions, then assigned universal right, open-differential left, ELSD left, and mount parts even though catalog fitment changes with side, limited-slip equipment, and axle family.

Visible front-differential leak or metal contamination in its lubricant
How to Fix
First confirm the vehicle is a 2008 4WD 4.7L model and identify its front axle and differential equipment from the VIN, build data, and sales codes. Reproduce the sound during a tight turn under power and under acceleration, constant load, deceleration, and coast. Inspect both CV boots for tears and grease, then check the joints, shafts, differential mounts, and related hardware for play or movement. If build data confirms the C200F front axle, follow the cited service-manual road test: warm the axle lubricant, compare the sound under load and coast, and inspect lubricant level plus ring-gear backlash and gear condition when the pattern points inside the axle. For a different axle family, use its specific service procedure. Turn the vehicle in both directions to load the axle bearings and compare the noise. Order a CV axle only after the failed side and limited-slip configuration are confirmed; order differential bearings, seals, or gears only after the axle family and internal fault are measured. Differential setup is specialist work, so do not buy a kit from noise alone.
Owner tips & cautions
WarningDo not order a front axle or differential kit from the noise description alone. Confirm 2008 4WD 4.7L scope, failed side, limited-slip equipment, axle family, and VIN/build data first.
TipPhotograph any torn boot, grease pattern, or differential leak and ask the shop to document when the sound changes: tight turn, acceleration, steady speed, or coast. Those patterns separate several possible causes.
WarningThe old axle cross-references and mount search were removed. ShowMeTheParts lists different limited-slip and non-limited-slip CV candidates plus multiple differential families for 2008, so none is universal.
On the 2011-2021 Jeep Grand Cherokee, grand Cherokee 4x4 differentials (and the transfer case) are a known spot for pinion-seal leaks — owners find gear oil weeping where the driveshaft meets the diff, leaving puddles and, if ignored, running the diff low on lube. A low/contaminated differential then produces a speed-related whine or howl (rising on acceleration or deceleration depending on which gear/bearing is loaded). RepairPal documents many pinion-seal/transfer-case leak cases on the platform. A caution: careless seal replacement (over-torquing the pinion nut and crushing the collapsible spacer) destroys pinion-bearing preload, so the repair must be done correctly.
Gear-oil puddle/residue at the driveshaft-to-differential joint
Speed-dependent whine or howl from front or rear axle
Whine changes on acceleration vs deceleration
Low differential fluid level
Metal glitter on the diff fill plug (advanced wear)
Transfer-case output seal also weeping
How to Fix
Inspect the front and rear diff pinion flanges and transfer-case output for gear-oil weepage; confirm fluid level. Replace the leaking pinion seal, marking pinion-nut position/turns to preserve preload (or setting new preload with a fresh crush sleeve) to avoid bearing damage. If gear whine is already present from prior low-lube running, evaluate the ring/pinion and bearings and refill with the correct spec gear oil. Address any transfer-case seal leaks at the same time.

On the 2011-2021 Jeep Grand Cherokee, grand Cherokees with the two-speed Quadra-Trac II / Quadra-Drive II transfer cases throw a 'Service 4WD System' message when the transfer-case shift actuator motor (or the transfer-case control module) fails, leaving the vehicle unable to engage Low range or Neutral and sometimes producing a grinding noise. Owners and shops report it is difficult to diagnose: replacing the actuator motor does not always fix it, and some vehicles ultimately need a transfer case. Codes such as C140F are associated with the actuator failure. It is a high-demand complaint because the warning is alarming and the off-road/low-range function is lost.
Scan for transfer-case actuator/control codes (e.g., C140F) before parts replacement. The shift motor is accessible after removing the belly skid guards (four bolts and a connector) and is the first replacement; if the fault persists, test the transfer case control module and wiring, and inspect the actuator's internal encoder ring/case for damage before condemning the whole transfer case. Verify any applicable recall coverage tied to the fault code.

On the 1999-2004 Jeep Grand Cherokee, the WJ's on-demand NV247 (Quadra-Trac II) and full-time NV242 (Selec-Trac) transfer cases suffer fluid leaks from the case split-line, rear output slip-yoke seal and a plugged vent, plus a pressure/heat issue: many 1999 units were filled with the WRONG fluid from the factory. Low/incorrect fluid leads to the NV247's progressive coupling binding, chatter on turns and eventual internal wear.
Common Symptoms
Fluid leak at the rear output seal or case seam
Low transfer-case fluid
Bind, chatter or hop on tight turns (NV247)
Whine/growl from the transfer case
Fluid pushed out of the vent when hot
How to Fix
Keep the transfer case topped and use the correct fluid — the NV247 requires Mopar/NV247 ATF (equivalent to Mobil 424 hydraulic-tractor fluid), NOT ordinary gear oil. Fix leaks by replacing the rear output/slip-yoke seal and resealing the case halves, and clear/replace the plastic vent cap so pressure can't push fluid past the seals. Verify factory fill on early 1999 units.

On the 2011-2021 Jeep Grand Cherokee, wK2 Grand Cherokees commonly develop a speed-dependent driveline vibration or shudder felt through the floor/seat, typically appearing around 45-75 mph and often worse under light acceleration or on deceleration. The rear driveshaft uses CV-style joints and a splined slip section; grease can migrate out of the slip joint and collect in the rubber accordion boot, the CV joints wear or bind, and the center support/CV angles fall out of spec, all producing the vibration. Motor and transmission mounts (which also fail on these trucks) can amplify or mimic the symptom, complicating diagnosis. Heavier V8/SRT/Trackhawk models with more torque tend to surface it sooner.
Vibration or shudder felt in floor/seat at 45-75 mph
Worse under light throttle or when decelerating
Droning/humming that rises with road speed
Grease slung inside the driveshaft boot area
Clunk on takeoff if joints are worn
Vibration reduced after mount replacement (partial cause)
How to Fix
Diagnose by roadtest and by inspecting the rear propshaft: clean redistributed grease out of the slip-joint boot and re-grease the slip yoke, check CV joints for play/binding, and verify driveshaft/pinion angles and center bearing condition. Rebalance or replace the rear driveshaft assembly if joints are worn. Confirm engine and transmission mounts are not collapsed (a frequent contributor). Replacing a worn rear driveshaft or reconditioning the slip joint typically resolves it.

On the 2014-2016 Jeep Grand Cherokee 3.0L EcoDiesel V6 (sales code EXF), a DEF/SCR warning or reductant-system DTC on a 2014-2016 Grand Cherokee EcoDiesel does not prove that the complete DEF tank has failed. FCA documentation shows materially different causes and remedies within this model range: one defined 2015 population received PCM software and a fluid-level reset for reductant codes, while a separate, narrowly defined 2015 VIN/build population with manufacturing contamination required several DEF/SCR components. Eligible vehicles that received the Approved Emissions Modification may also have extended-warranty coverage for multiple DEF-system parts and diagnostic scanning. The previous card collapsed all of these paths into one integrated-tank diagnosis and published two unverified retail searches.
Common Symptoms
Malfunction indicator lamp
Service DEF or reductant-system warning
A stored DEF/SCR pressure, heater, quality, or system-performance DTC
How to Fix
Record the exact DTCs, freeze-frame data, warning text, VIN, build date, and current PCM software level. Have an EcoDiesel-capable shop or Jeep dealer follow the code-specific FCA diagnostic procedure and check whether a VIN-specific service action, applicable software update, or AEM extended warranty applies. Do not infer a failed tank from P20E8, P204F, P20EE, or another reductant code alone: verify the relevant pressure, heater, level/temperature input, fluid quality/contamination, delivery line, injector, SCR catalyst, wiring, and control-software path specified for that VIN. Replace only the component the tests and applicable FCA procedure identify. No retail part is published until the failed component and VIN fitment are confirmed.
Owner tips & cautions
TipBring the exact code, freeze-frame data, VIN, build date, and software level to diagnosis; FCA's documented remedy changes with those details.
WarningDo not buy a complete DEF tank from the warning message alone. FCA records show that software, contamination, the tank, lines, injector, catalyst, pump, sensors, or related controls can require different service paths.
TipFor a 2014-2016 EcoDiesel that received the Approved Emissions Modification, check the transferable extended-warranty term before paying for DEF/SCR diagnosis or covered parts.
On the 2018 Jeep Grand Cherokee 6.2L supercharged HEMI V8 (sales code ESD), fCA TSB 18-001-26 covers a 2018 WK Grand Cherokee equipped with the 6.2L supercharged ESD engine and 8HP95 DFS transmission when P0420 and/or P0430 is stored. A customer may also report reduced engine power associated with catalyst damage and restricted exhaust flow. The bulletin identifies PCM software as the cause addressed by its repair procedure. It does not apply to the 3.6L Pentastar population in the old card and does not name an upstream or downstream oxygen sensor as the repair.
Malfunction indicator lamp with P0420 and/or P0430
Possible reduced engine power if catalyst damage has restricted exhaust flow
How to Fix
Confirm the vehicle is a covered 2018 WK with engine sales code ESD and transmission sales code DFS, save the DTC and freeze-frame information, and check the VIN and current calibration level. Follow FCA TSB 18-001-26: maintain the specified battery voltage, reprogram the PCM with the latest software using wiTECH or equivalent, and clear DTCs set during programming. If P0420/P0430 returns, exhaust restriction or loss of power remains, or other DTCs are present, continue with the current factory catalyst, fuel-control, misfire, exhaust-leak, and sensor diagnostics for the exact vehicle. Do not buy oxygen sensors or catalytic converters from the code alone.
Owner tips & cautions
WarningDo not use this bulletin on a 3.6L Grand Cherokee. Its exact scope is the 2018 6.2L supercharged ESD/8HP95 DFS application.
TipAsk the shop to record the original calibration, completed flash, cleared DTCs, and post-flash result before any catalyst or sensor purchase is discussed.
On the 2015 Jeep Grand Cherokee, fCA TSB 25-002-15 Rev. A covers a narrow population of 2015 WK Grand Cherokee vehicles built on or after November 16, 2014 and on or before January 17, 2015. On a covered vehicle with P0455 and/or P0456, a split evaporative-emissions purge-valve hose can prevent the system from sealing. The bulletin specifies 68189075AE for the 3.6L ERB engine and 68189065AD for the 5.7L EZH engine. It does not support the old card's blanket 2005-2021 claim that these codes are an ESIM failure.
Visible split in the purge-valve hose on a covered build
How to Fix
Record P0455/P0456 and any additional DTCs, confirm the vehicle is a 2015 WK within the bulletin's build window, and check the VIN in the current dealer system for RRT/VIP history. Follow the current EVAP diagnostic procedure and inspect the purge-valve hose for the split described by TSB 25-002-15 Rev. A. If the hose is confirmed, replace 68189075AE on a 3.6L ERB vehicle or 68189065AD on a 5.7L EZH vehicle, then clear the code and complete the appropriate EVAP verification. If the VIN/build/symptom does not match, perform the current smoke/leak test and applicable PCM update checks before replacing an ESIM, canister, capless-filler component, valve, or hose.
Owner tips & cautions
WarningP0455/P0456 does not identify an ESIM, gas cap, canister, or hose by itself. Match the build window and inspect or smoke-test the system before buying a part.
TipUse the VIN and engine sales code to distinguish the 3.6L and 5.7L purge hoses before ordering.
On the 2011-2021 Jeep Grand Cherokee, p0442 (small EVAP leak, roughly a 0.020–0.040 inch pinhole) is very common on the WK2 Grand Cherokee. The two dominant causes are a degraded gas cap rubber seal and, specific to this platform, a failed Evaporative System Integrity Module (ESIM) mounted in the rear driver-side wheel well. The ESIM is a well-documented WK2 failure point and often fails before other EVAP components; it is known to pass a smoke test yet still set the code because its internal switch fails to report the correct state to the PCM. A vapor canister purge valve stuck slightly open is a secondary cause. There are typically no drivability symptoms beyond the check engine light, and the code can be intermittent (may clear after a few good drive cycles once the cap is tightened).
Start with a new OEM Mopar gas cap and confirm it clicks/seals; clear the code and drive several cycles. If it returns, replace the ESIM in the rear driver-side wheel well (accessed behind the fender liner, on the charcoal canister). If still present, smoke-test the EVAP system to find hose/purge-valve/canister leaks.
On the 2005-2021 Jeep Grand Cherokee, warm air, a charge that does not last, or a compressor that will not engage can be consistent with a refrigerant leak, but those symptoms do not identify the condenser by themselves. Leaks can occur at lines, seals, service ports, the compressor, evaporator, receiver/drier, or condenser, while air-door, sensor, fan, electrical, or control faults can also reduce cooling. Low refrigerant pressure can cause the control system to inhibit compressor operation. The prior card incorrectly treated the front-mounted condenser as the leading universal cause and mixed generations, engines, integrated components, and part numbers without a complete leak diagnosis.
Common Symptoms
A/C blows warm or only slightly cool air
Cooling returns after a recharge and then fades
Low system pressure prevents compressor operation
Dye, oily residue, detector response, or physical damage is found at the condenser
How to Fix
Have qualified A/C service personnel identify the refrigerant on the underhood label, recover and measure the existing charge with compatible equipment, scan the HVAC/powertrain systems as applicable, and perform pressure and cooling-performance checks. Leak-test the entire system with approved fluorescent dye and/or an electronic detector and inspect all connections, lines, ports, compressor, evaporator drain, receiver/drier, and both faces of the condenser. Replace a condenser only when dye, detector response, oily residue, or visible physical damage confirms that it leaks. Use the exact VIN, platform, engine, drivetrain/cooler configuration, port layout, dimensions, and current supersession to select the assembly; 2021 WL/Grand Cherokee L applications must not be matched to a WK condenser. Replace disturbed seals and any separately required drier according to the exact service information, add only the specified oil amount, evacuate the system, verify vacuum integrity, and charge the exact label quantity. Do not use stop-leak or mix refrigerants or service equipment.
Owner tips & cautions
WarningDo not buy a condenser because the A/C is warm or because a recharge leaked down. The exact leak location and any separate control or air-door fault must be proven first.
WarningAvoid stop-leak products. FCA warns they can contaminate the system and damage recovery, evacuation, and charging equipment.
On the 2005-2021 Jeep Grand Cherokee, grand Cherokees develop heater-core problems from two directions: internal clogging (residual casting sand/scale restricting the fine tubes, producing weak or no heat) and leaks at the core or its plastic firewall inlet/outlet elbows (producing a sweet coolant smell, a greasy fog film on the inside of the windshield, and a damp passenger-side floor). A leaking core also slowly loses coolant and can lead to overheating. The repair is labor-intensive because the dash must be removed to reach the core buried in the HVAC housing, so misdiagnosis is costly.
Confirm the diagnosis: sweet smell + foggy windshield + wet passenger carpet = leaking core; cold-only output with good coolant flow points to a clogged core (attempt a back-flush first). Pressure-test the cooling system and inspect the plastic heater pipes/elbows at the firewall, which can be replaced separately if that's the leak point. If the core itself leaks or is clogged, replace the heater core (dash-out labor). Refill and bleed the cooling system afterward and verify heat and no coolant loss.

On the 1999-2004 Jeep Grand Cherokee, on a WJ Grand Cherokee with manual temperature control, the lower blower speeds route through a resistor while the highest speed bypasses it. A blower that still runs on high but loses lower speeds can therefore point toward the resistor circuit, but the factory test also requires checks of the blower switch, wiring, terminals, fuse, and related connections. Automatic Zone Control uses a different electronic power module and is not the same repair. The old card incorrectly combined 1994-2004 generations, manual and automatic HVAC systems, and four possible parts in one shopping list.
Possible heat damage or looseness at the resistor connector
How to Fix
First verify the vehicle is a 1999-2004 WJ with manual temperature control rather than Automatic Zone Control. Confirm which speeds work, inspect the resistor connector and harness for heat damage or loose terminals, and test the blower switch, resistor circuit, power, ground, and blower current draw using the factory wiring information. Replace the resistor only if the test condemns it: 4720278 for the applicable 1999 manual-control vehicle or 5014212AA for the applicable 2000-2004 manual-control vehicle, subject to VIN and connector verification. If the vehicle has Automatic Zone Control, use the AZC self-test and controller circuit procedure instead of ordering either manual-control resistor. Recheck every speed and connector temperature after repair.
Owner tips & cautions
WarningManual climate control and Automatic Zone Control do not use the same speed-control part. Confirm the HVAC control type before ordering.
TipInspect the connector for melting or loose terminals and check blower current draw; replacing only the resistor can fail again if the underlying circuit problem remains.
On the 2019 Jeep Grand Cherokee, on 2019 model-year Jeep Grand Cherokee (WK) vehicles, an ABS warning that diagnosis traces to a wheel-speed circuit may be caused by an incompletely latched connector, water intrusion and corroded connector pins, rust or contamination at the sensor and tone wheel, or a faulty sensor. FCA warns that replacing a good sensor while leaving a damaged harness in place can cause the concern to return. The previous card incorrectly generalized this condition across 2011-2021 vehicles, named the right-front sensor as a common cause, listed unsupported DTCs and symptoms, and presented three universal repair parts.
Common Symptoms
ABS warning light illuminated
How to Fix
Read the ABS module and compare individual wheel-speed live data to isolate the affected circuit. Inspect the connector latch, pins, and harness for water intrusion, corrosion, routing problems, or damage; replace a damaged harness rather than the sensor. Inspect and clean the sensor mounting area and tone wheel, reinstall the sensor, and retest the signal. Replace the sensor only when electrical and signal testing confirms it is faulty, then clear faults and verify normal wheel-speed data on a road test. Confirm any replacement by VIN and installed equipment before ordering.
Owner tips & cautions
WarningDo not order a wheel-speed sensor from the warning light alone. FCA specifically documents corroded connector pins and tone-wheel rust that can make a good sensor appear faulty.
TipAsk the shop to record the ABS fault and individual wheel-speed live data, then document the connector, harness, and tone-wheel inspection before authorizing a part.
WarningThe corrected scope is 2019 model year only. The prior 2011-2021 range and right-front-specific claim were removed because the reviewed FCA evidence does not establish them.
On the 2000-2010 Jeep Grand Cherokee, repeated owner complaints describe front brake pulsation, steering wheel shake under braking, and rotors that develop thickness variation or hot spots well before expected service life. This issue is especially well known on WJ models, though WK owners also report premature rotor wear. The problem is often worsened by heavy vehicle weight, marginal rotor capacity, seized slide pins, or uneven lug torque after service.
Common Symptoms
Brake pedal pulsation
Steering wheel shakes when braking
Premature front pad wear
Burning smell after braking
Vehicle pulls during braking
How to Fix
Inspect rotor runout, thickness variation, pad wear pattern, caliper slide movement, and hub face cleanliness. The lasting repair is usually quality rotors and pads, proper hub cleaning, lubricated slide pins, and torqueing wheels to spec; if calipers are sticking, replace or rebuild them. Simply machining thin rotors often leads to quick recurrence.
Owner tips & cautions
TipOwners commonly recommend premium coated rotors and ceramic or severe-duty pads instead of economy parts, plus replacing hardware and lubricating slide pins every brake job.
TipUse a torque wrench on lug nuts and clean rust from the hub face to prevent rotor runout after installation.
On the 2019-2022 Jeep Grand Cherokee, fCA TSB 09-019-23 covers a cold ticking noise from the exhaust-manifold area on 2019-2021 WK and 2021-2022 WL Grand Cherokee vehicles with the 5.7L EZH or EZC engine. The bulletin's repair condition is a cracked exhaust manifold, not a blanket conclusion that every HEMI tick is a broken bolt, lifter, or manifold. FCA directs the technician to start the engine cold, identify the side of the noise, remove the suspect heat shield after cooling, and visually distinguish an actual crack from a casting line or fin.
Common Symptoms
Ticking noise localized to an exhaust-manifold area when the engine is cold
Tick diminishes or stops after the engine warms
Visible crack in the suspect manifold after the heat shield is removed
How to Fix
Confirm that the tick starts cold and comes from the manifold area, then cool the engine and inspect the suspect manifold as FCA directs. Replace only a manifold that is confirmed cracked. Use the complete updated FCA kit for the affected side: 68591586AA left or 68591591AA right for WK/WD/WL applications. FCA says to install every supplied component - manifold, gasket, fasteners, heat shield, and tie bar - and replace all fasteners; the right-front fastener 06510140AA is shorter than the others. If no crack is found, stop and diagnose other exhaust, ignition, injector, or valvetrain causes before buying a kit. Verify VIN, engine sales code, side, sealed kit contents, and current supersession before ordering.
Owner tips & cautions
WarningDo not order a manifold kit from the word 'tick' alone. FCA's procedure requires the cold-noise source and an actual manifold crack to be confirmed first.
TipUse every component in the updated kit. FCA specifically calls for the supplied gasket, new fasteners, heat shield, and tie bar, including the shorter 06510140AA fastener at the right-front position.
On the 2000-2010 Jeep Grand Cherokee, a very common Grand Cherokee problem across both WJ and WK generations is failure of the HVAC blend doors or their actuators. Owners report loss of temperature control, air stuck on hot or cold, clicking behind the dash, or dual-zone systems blowing different temperatures side to side. On WJ models, the plastic blend doors themselves commonly crack or detach; on WK models, actuator motors and door linkages are frequent failure points.
Common Symptoms
No heat from vents
A/C stuck on hot or cold
Driver and passenger vents different temperatures
Clicking or knocking behind dash
Airflow mode changes incorrectly
How to Fix
Diagnose by commanding temperature changes and listening for actuator movement or clicking, then verify door travel with a scan tool or manual inspection where possible. Repair ranges from replacing an actuator to installing updated blend-door repair kits; on some vehicles, full HVAC box access requires major dash disassembly, though aftermarket repair kits can reduce labor on WJ models. If poor heat is also present, confirm the heater core is not restricted before replacing doors.
Owner tips & cautions
TipOn WJ models, many owners use aftermarket metal or reinforced blend-door repair kits to avoid repeat failure and reduce dash removal labor.
TipBefore replacing parts, run the HVAC calibration/self-test procedure and verify coolant flow through the heater core so a clogged core is not mistaken for a door problem.
On the 2011-2023 Jeep Grand Cherokee, owners of panoramic-sunroof-equipped Grand Cherokees (WK2 and 5th-gen WL) report the glass panel spontaneously shattering or 'exploding' with a loud pop while driving on clear days, with no impact. NHTSA complaints and forum reports describe the tempered panel bursting outward/inward, sometimes at low mileage. Suspected causes include factory pre-stress in the tempered glass, ceramic-frit edge stress, thermal cycling, and frame/mechanism stress on the panel. Beyond the repair cost, flying glass and startle-factor while driving make it a safety concern; owners frequently struggle to get warranty coverage and pay out of pocket.
Spider-cracked or collapsed panoramic panel with no impact
Glass falling into cabin (often caught by sunshade)
Occurs at speed on clear days
Wind noise/water entry after the panel breaks
Sudden startle event while driving
How to Fix
There is no preventive repair — the panel must be replaced with new tempered glass (dealer or auto-glass shop), and owners should verify the sunroof frame/track and drains are correct so the replacement isn't re-stressed. Document the event and file an NHTSA complaint (helps trigger any future investigation/coverage) and check comprehensive insurance, which often covers glass with low/no deductible. Retain any FCA/Stellantis goodwill-assistance option for low-mileage vehicles.
