1994-2026 Jeep Wrangler Problems: 73 Known Issues

Chrysler recalled 32,863 vehicles — 2018-2024 Wrangler and 2020-2024 Gladiator — because the instrument panel cluster can develop an internal short circuit and fail outright, taking the speedometer, fuel gauge, and every telltale and warning lamp with it. NHTSA classified this as a failure to comply with FMVSS 101, 'Controls and Displays.' Unlike a software-blanking fault this is a hardware defect inside the cluster, and the declared remedy is replacement, not a reflash. Owner notification letters went out between October 3, 2024 and January 23, 2025.

NHTSA campaign 23V787000 covers certain 2021-2023 Jeep Wrangler plug-in hybrid vehicles whose high-voltage battery may fail internally and cause a fire while parked or driving. That campaign was replaced by 24V720000, which was then replaced by current campaign 25V741000. Vehicles previously repaired under the earlier campaigns may need the current remedy.

JK owners report the fuse and relay module (TIPM) causing electrical faults on its own: dash lights coming on, washers spraying, wipers, horn and turn signals operating, the engine running after the key is off or dying when the wipers are switched on. One owner reports the faults returned a few months after a new replacement module was fitted. It affects 2007-2018 Jeep Wrangler and Wrangler Unlimited (JK) models with any engine.

Wrangler 4xe owners report repeated dead 12V auxiliary batteries and, in some cases, complete electrical shutdowns. Several owners found the included Level 1 charger drains the 12V battery after the high-voltage pack reaches 100%, leaving the vehicle unresponsive within days. Beyond no-starts, some 4xe vehicles abruptly lose power or shut off while driving (often when EV range is exhausted), and owners have had to disconnect and reconnect the 12V battery to revive the vehicle, sometimes with persistent warning lights afterward. Dealers frequently cannot locate the parasitic drain even when the 12V battery tests good.

The 2018 Jeep Wrangler is included in FCA US recall 18V332000, which covers a defect that can prevent the cruise control system from shutting off. NHTSA's record states that if a short circuit occurs in the vehicle's wiring while cruise control is engaged, the driver may not be able to cancel it — neither by pressing the brake pedal nor by switching the system off manually. The Wrangler would then hold its set speed, or possibly accelerate, despite the driver's attempts to deactivate it. NHTSA's stated consequence is an increased risk of a crash. Because 2018 was the only Wrangler model year named in this campaign, owners of a JL or a final-year JK from that year should check their VIN rather than assume the truck is clear.

Wrangler models built for the 2017 and 2018 model years are included in FCA US safety recall 18V524000 (Chrysler campaign number U87). The powertrain control module in these Jeeps may contain a circuit-board voltage regulator chip that can fail. When that chip fails, the Wrangler can stall while being driven or refuse to start at all. NHTSA classifies the defect under electrical system wiring, front underhood, and warns that a vehicle stall increases the risk of a crash. The campaign spans a large slice of the FCA lineup for those years, but each affected vehicle is covered individually by VIN.

eTorque (mild-hybrid) Wranglers replace the conventional alternator/starter with a 48V belt-driven motor-generator (BSG/MGU) plus a 48V power pack unit (PPU) and a 12V system. Owners report charging-system failures, battery warning lights, rough/failed auto-starts during stop-start cycling, voltage drops, stalling, and no-starts. The most common culprit is the 48V PPU rather than the MGU itself, though both fail. The MGU/BSG (Mopar 68452771AF) is expensive and, once replaced, must be programmed with the dealer scan tool or it will not function. Components fall under the 8-year/80k-mile hybrid warranty, but out-of-warranty repairs are costly.

Chrysler recalled 320,068 vehicles — including certain 2020-2025 Wrangler 4xe — because the high-voltage traction battery can fail internally and start a fire whether the vehicle is parked or being driven. This is a separate campaign from the 4xe engine sand-casting-contamination recall; here the defect is inside the HV pack itself. Owners were told to park outside away from structures and to stop charging entirely until remedied, and for months after the December 17, 2025 notification letters no final remedy existed. NHTSA complaints from 2025 Wrangler 4xe owners document the practical consequences: vehicles that cannot be garaged or charged, dealers refusing to open STAR cases, and at least one 2025 Wrangler that caught fire at the passenger front wheel area after a sudden loss of power on the interstate with a family aboard.

An over-the-air Uconnect update pushed on Friday, October 10, 2025 caused an incomplete communication handshake between the Telematics Box Module (TBM) and the Hybrid Control Processor (HCP). The HCP resets, and the vehicle loses all motive power — gasoline and electric — with no warning. NHTSA received well over 100 complaints in the two weeks following the update, nearly all filed in October 2025. Owners describe driving normally for 2-10 minutes, then all dash lights flashing, a 'Shift into PARK to restart' message, complete loss of throttle, and in many cases loss of power steering and brake assist while rolling. Restarting restores operation for a few more minutes before it repeats. Several owners were stranded in traffic or on highways; some reported code P1E1D. Stellantis cancelled the update and pushed an automatic rollback the following evening, then filed a formal safety recall on October 17, 2025 covering 24,238 units of 2023-2025 Wrangler 4xe.

The 8.4-inch Uconnect touchscreen suffers physical delamination: the optically-clear adhesive (OCA) bonding the glass digitizer to the display breaks down under repeated dashboard heat cycling. This produces bubbles and cloudy patches, then 'ghost touches' where the screen registers phantom presses (jumping menus, dialing on its own, changing climate), and in severe cases the liquefied adhesive drips onto the center console. This is mechanically distinct from the already-documented Uconnect freeze/reboot software faults. Owners outside the factory warranty often end up paying out of pocket.

Early JK Wranglers commonly develop instrument-cluster faults: speedometer, tach, fuel, and temp needles that stick, read erratically, or drop to zero, and in some cases full cluster/CCN module failure. Owners report needles losing their retaining adhesive on the stepper-motor shafts.

The 8.4-inch Uconnect 4 and the newer Uconnect 5 head units frequently freeze, glitch, reboot multiple times before booting, or go to a black screen. A common and safety-relevant failure mode is the rear backup camera failing to display when shifted into Reverse, showing a blue/black screen, or staying on after moving forward. The system is sensitive to 12V voltage drops (a weak auxiliary/aux battery makes it lag, reset, or refuse to boot), and many JLs ship with loose fuses that aggravate the problem. For 2024 Wranglers with Uconnect 5, Stellantis has issued radio software update bulletins (e.g., TSB 08-203-24, an over-the-air update for the 12.3-inch display).

The automatic engine start-stop system can be problematic, with complaints about delayed restarts, aggressive shutoffs, and system deactivating in conditions where owners expect it to work. The system defaults to ON each time the vehicle starts.

JK owners with power windows report windows that stop working, either all at once until the engine is restarted or one window whose motor runs one way only. Owners suspect the switch, a connector disturbed by door removal, or the window motor or regulator; the cause was not confirmed in these reports. It affects only Jeep Wrangler and Wrangler Unlimited (JK) models with power windows. Owner reports name 2010 and 2011 JKs.

TJ Wranglers commonly lose one or more cabin fan speeds because the blower motor resistor overheats or the connector melts. Owners usually notice the fan only works on high speed, or stops working on lower settings first. The issue is well documented in owner forums and service parts databases, especially on vehicles with aging blower motors that draw excess current.

Late-TJ 4.0L Wranglers are well known for Oil Pump Drive Assembly (OPDA) failures, often described by owners as the 'screaming monkey' chirp or squeal from the engine bay. The OPDA can bind or wear internally, which may damage the camshaft gear and affect oil pump drive timing. If ignored, the issue can escalate from noise and check-engine lights to expensive internal engine repair.

NHTSA campaign 25V766000 covers certain 2024-2025 Jeep Wrangler 4xe plug-in hybrid vehicles. Casting-sand debris inside the engine can contaminate internal components and cause catastrophic engine failure, an unexpected loss of drive power, or an engine-compartment fire. Owners may notice engine knocking or a malfunction indicator lamp before failure.

The 4.0L inline-six heads carrying casting number 0331 (used on roughly 1999-2002 builds) were designed with enlarged intake/exhaust ports but left the deck wall between cylinders #3 and #4 too thin. Over high-mileage thermal cycling the head cracks in that area (visible through the oil-filler cap between the #3/#4 valve springs), often letting coolant weep into the combustion/oil galleries.

Owners of 3.6L JK Wranglers report a persistent ticking from the top of the engine; dealers replaced rocker arms and lifters to cure it. Owners report that leaving it alone let a damaged rocker grind the camshaft lobe, turning a small repair into a camshaft replacement, and one owner reports the engine eventually lost compression. It affects 2012-2018 Wrangler and Wrangler Unlimited (JK) models with the 3.6L Pentastar V6, and owner reports name 2014 and 2015 JKs. In the linked owner reports the tick showed up at 35,000 and 167,500 miles, both on 2014 models.

On 2012 and select 2013 Wranglers with the 3.6L engine (sales code ERB), the left cylinder head can develop valve guide and valve seat wear, setting misfire codes P0300, P0302, P0304 or P0306 and turning on the check-engine light. FCA extended coverage on the left cylinder head to 10 years or 150,000 miles from the in-service date under program X56; that period has now ended on most or all of these Jeeps.

The crankshaft position sensor (CPS) on the 4.0L (and 2.5L) inline engines mounts on the transmission bellhousing and is exposed to severe heat soak. As it ages it develops intermittent thermal failure: the engine stalls without warning once hot, then refuses to restart until it cools, after which it runs fine again — a maddening, hard-to-replicate fault. Frequently the CPS fails with NO check-engine light and NO stored code, so it is commonly misdiagnosed. It is a roadside-safety concern because the stall is sudden.

Owners of 3.6L JK Wranglers report the engine using oil quickly, in one case 3.5 quarts in under two weeks with the engine going into limp mode. Some engines were replaced. Forum members report that dealers blamed some cases on dirt drawn in past aftermarket cold-air intakes, and members suspected a neglected air filter in another; the cause on any one Jeep has not been confirmed. It affects 2012-2018 Jeep Wrangler and Wrangler Unlimited (JK) models with the 3.6L Pentastar V6. Owner reports name a 2012 JKU, with the problem showing up at 74,000 km (about 46,000 miles) and at 60,000 miles on a 2012.

The 4.0L coil-rail ignition system used on TJ Wranglers is known to develop internal failures that cause intermittent or persistent misfires. Owners report rough idle, hesitation, flashing check-engine lights, and cylinder-specific misfire codes, often after moisture intrusion, age, or heat exposure. Because the one-piece pack houses three coils that each fire a pair of cylinders (waste spark), one failed coil can cause misfires on two cylinders, and the whole pack is replaced as an assembly.

TJ Wranglers with the 4.0L frequently develop catalytic converter deterioration, especially on higher-mileage vehicles and 2000-2006 emissions configurations using multiple converters/pre-cats. Owners commonly report a check-engine light with catalyst-efficiency codes, sulfur smell, rattling substrate, or loss of power if the converter begins to clog.

JK owners report the red electronic throttle control (lightning-bolt) light coming on, often with the traction control light, and the engine going into reduced-power limp mode with a raised idle and slow throttle response. The cause is hard to pin down: owners point to wheel-speed or camshaft sensors, a front wheel bearing, or a connector left loose after other engine work. It affects 2007-2018 Jeep Wrangler and Wrangler Unlimited (JK) models with the 3.8L or 3.6L V6. The owner reports are from 2008 (3.8L), 2012 and 2014 JKs; the 2012 had 95,000 miles when it happened.

Owners of 3.6L JK Wranglers report oil leaking from the plastic oil filter and oil cooler housing that sits in the valley between the cylinder heads. The oil pools in the valley and runs down the back of the engine onto the transmission bell housing, so it is often mistaken for a rear main seal leak; one owner reports a dealer found the housing cracked with low oil pressure. It affects 2012-2018 Wrangler and Wrangler Unlimited (JK) models with the 3.6L Pentastar V6, and owner reports name 2013, 2014 and 2015 JKs. In the linked owner reports the leak showed up at 60,000 km (about 37,300 miles), at 52,000 and 70,000 miles on 2013 models, and at 80,000 miles on a 2015.

The 3.8L V6 (used in 2007-2011 JK Wranglers) is widely reported to consume oil, with affected examples burning roughly a quart every 1,000-2,000 miles while others see little loss. Owners and forum techs attribute it to the low-tension piston rings combined with the U.S. 5W-20 oil specification (Jeep specs heavier 5W-30 in export markets), which lets thin oil slip past the rings and burn. In severe cases low oil from unnoticed consumption contributes to ticking, spun main bearings, or ring failure, so monitoring level between changes is important.

The 4.0 routes oil through a cast oil-filter adapter housing bolted to the block behind the filter, sealed by a set of rubber O-rings. The O-rings harden and shrink with age/heat, producing a persistent oil leak on the passenger side of the block that runs down the bellhousing and is very commonly misdiagnosed as a rear main seal. A classic high-mileage TJ/XJ/ZJ oil leak.

A leaking rear main seal is nearly universal on high-mileage 4.0 Wranglers — the two-piece crankshaft seal hardens and weeps oil at the back of the block, dripping onto the bellhousing and often collecting at the transmission. It is frequently confused with an oil-filter-adapter or oil-pan-gasket leak.

One of the most common 4.0 oil leaks: the valve cover gasket hardens and seeps, typically worst at the rear of the head, leaving oil and grime down the back of the block and sometimes dripping onto the exhaust (burning-oil smell). Frequently mistaken for a more serious rear main or head-gasket leak.

JK owners report engine oil on the bell housing that looked like a rear main seal leak but came from the oil pan seal, in some cases after one or more rear main seals had already been replaced. Oil from the pan seal runs back along the pan to the bell housing, which makes the source hard to see. It affects 2007-2018 Jeep Wrangler and Wrangler Unlimited (JK) models with the 3.8L or 3.6L V6. Owner reports name a 2010 3.8L and a 2013 3.6L JK. On the 3.6L the upper oil pan is sealed with RTV sealant rather than a gasket.

Certain Wranglers were built with a Takata front passenger airbag inflator whose propellant can degrade after long exposure to high humidity, high temperatures and temperature cycling. If the passenger airbag deploys in a crash, the inflator may rupture and send metal fragments into the cabin at high speed, which may injure or kill occupants. It affects certain 2010-2016 Jeep Wrangler and Wrangler Unlimited (JK) built April 29, 2009 to September 17, 2016 that were assembled with a passenger airbag inflator included in Takata's January 2, 2019 recall expansion (FCA recall V01). Not every Wrangler in these years is included; a VIN check confirms it.

A common TJ/LJ Wrangler failure is the steering column clock spring wearing out internally, which breaks electrical continuity to the driver airbag, horn, and cruise-control switches. Owners typically report an illuminated airbag light along with an inoperative horn and cruise control. This was widespread enough to generate many owner complaints; the only TJ clock-spring recall (98V046) covered 1997 models, and NHTSA lists no clock-spring recall for 2000-2006 Wranglers.

FCA US (Stellantis) recalled certain 2023-2024 Jeep Wrangler models because the steering column control module may not have been welded properly. A module with a faulty weld can prevent the driver's air bag from deploying in a crash, so the Wrangler does not meet Federal Motor Vehicle Safety Standard No. 208, "Occupant Crash Protection." NHTSA campaign 24V199000 covers this defect across a group of Chrysler, Jeep and Ram vehicles; FCA's internal recall numbers are 14B, 33B, 34B, 35B and 36B. Because the defect is inside the steering column, there is nothing an owner can see or hear from the driver's seat — the air bag simply may not fire when it is needed.

FCA bulletin 08-005-17 REV. A covers an airbag or traction-control warning light on 2011-2016 JK Wranglers caused by the steering-column clockspring, with driver-airbag circuit, steering-angle-sensor, speed-control switch or steering-wheel control codes stored. A failed clockspring can leave the driver airbag circuit open. It applies to 2011-2016 Jeep Wrangler and Wrangler Unlimited (JK) left-hand-drive models built on or after February 16, 2010 and before May 2, 2016, when one of the bulletin's trouble codes is stored. A 2016 built on or after May 2, 2016 is outside the bulletin. Right-hand-drive JKs were covered instead by safety recalls S40 (NHTSA 16V-288, built through May 2, 2016) and 27B (NHTSA 24V-196, 2016 models built May 3 to September 16, 2016).

In certain crashes the headlamp can rotate and pull the wiring off the front impact sensor before the airbag controller records the impact signal. The frontal airbags and seat-belt pretensioners may then not deploy when they should, increasing the risk of injury. It affects 2016 and 2017 Jeep Wrangler and Wrangler Unlimited (JK) built before August 14, 2016 (FCA recall S76; production from June 2015).

Chrysler recalled 32 model year 2026 Jeep Wranglers because the child-seat top-tether anchor welds on the second-row right-side seat frame may be insufficient. Under crash loading the anchor can pull away from the frame, so a top-tethered child restraint would not be properly held. NHTSA recorded this as a failure to comply with FMVSS 225, 'Child Restraint Anchorage Systems.' The build population is very small, but the consequence is severe and the remedy is a full seat frame replacement rather than a repair, which indicates the weld defect cannot be corrected in place.

Chrysler recalled 22,906 model year 2024-2025 Wranglers because the remote start antenna cable can be pinched during assembly. The damaged cable can leave the tire pressure monitoring system unable to detect low tire pressure, so the driver may get no warning of an underinflated tire. NHTSA cited the vehicles as non-compliant with FMVSS 138, 'Tire Pressure Monitoring Systems.' FCA's recall report notes that the TPMS indicator light will illuminate on the cluster when the condition is present.

The solid-front-axle JL Wrangler continues to produce death-wobble reports on brand-new 2024 and 2025 trucks. NHTSA complaints describe the trigger consistently: crossing a bridge expansion joint, road seam or rough patch at roughly 45-75 mph, after which the steering wheel and front end oscillate side to side violently until the driver brakes below about 50 mph. A recurring secondary complaint is that dealers cannot reproduce the event and therefore decline warranty repair. Root causes on the JL are a worn or loose track bar and track-bar bracket, a weak steering damper, loose tie-rod hardware, worn control-arm bushings, or wheel/tire imbalance — any of which lets the axle's natural caster-induced oscillation self-amplify.

NHTSA campaign 26V363000 covers certain 2021-2025 Jeep Wrangler, Wrangler 4xe and Gladiator vehicles. High resistance at the electric-hydraulic power steering pump electrical connection may overheat combustible material and cause a vehicle fire, including while the vehicle is parked with the ignition off. Loss of steering assist or a Service Power Steering message may occur.

JK owners report a violent side-to-side shaking of the front end and steering wheel after hitting a bump at speed, which stops only when the vehicle slows down. Owners trace it to loose or worn front steering and suspension parts, most often the track bar and its bolts, ball joints and tie-rod or drag-link ends; it is reported most often on lifted or modified Jeeps. It affects 2007-2018 Jeep Wrangler and Wrangler Unlimited (JK) models with any engine.

JL Wranglers (and the related Gladiator) are widely reported to have vague, loose on-center steering that wanders and drifts at highway speed, forcing constant correction. This is distinct from death wobble — it is excessive play and tracking instability in the steering gear itself. Stellantis acknowledged it with TSB 08-074-20 (2018-2020 JL, 2020 JT), which replaces the original aluminum-housing steering gear box with an upgraded steel unit and updates the EHPS software if required; a related steering-damper customer-satisfaction action (V41) was also issued for some 2018-2019 units. NHTSA has logged numerous owner complaints. The steel box tightens on-center feel and reduces wander but does not always fully eliminate tracking sensitivity.

The solid-axle Dana 30 front end uses pressed-in upper and lower ball joints that wear out on high-mileage Wranglers, especially lifted rigs with larger tires. Worn ball joints introduce play in the steering knuckle, causing clunking over bumps, loose or wandering steering and uneven tire wear. Worn ball joints are also a leading mechanical contributor to front-end vibration.

Distinct from frame corrosion, the steel body tub rusts from the inside out on older Wranglers, especially in salt regions. The spot-welded body-mount channels ('torque boxes') under the floor, the floor-pan seams, and the rocker areas trap moisture and rot around the three body mounts on each side. Buyers of high-mileage TJ/YJ examples should check these areas closely.

Rust-through of the TJ frame, especially near the lower control arm mounts, skid plate area, and rear trailing arm sections, is one of the most serious age-related Wrangler problems. In rust-belt states, owners report perforation severe enough to affect suspension mounting integrity and vehicle safety inspections. Corrosion often starts from the inside of the boxed frame where mud and moisture collect, so the outside can look better than the structure actually is.

JK owners report the tempered rear glass of the hardtop shattering with no impact, while driving or while the Jeep was being loaded with nothing against the glass. Owners suspect a defect in the glass; the cause has not been confirmed. It affects only Jeep Wrangler and Wrangler Unlimited (JK) models with a factory hardtop. Owner reports name a 2012 Wrangler Unlimited and a 2014 Wrangler Unlimited Sahara. Soft-top Jeeps are not affected.

Stellantis bulletin 31-002-22 applies to 2018-current JL Jeep Wrangler aluminum panels with corrosion or paint bubbling on hoods, hinges, doors, fenders, swing gates or other exterior surfaces. The bulletin warns that ferrous-metal cross-contamination during preparation can lead to galvanic corrosion.

JL Wranglers (and Gladiators) are widely reported to have windshields that crack, chip and fracture from minor road debris impacts that would not damage a typical windshield — sometimes within days or a few miles of delivery. The near-vertical windshield and apparently thin glass make it especially vulnerable. A class action alleges 2016-present Wrangler/Gladiator windshields are 'extremely prone' to cracking; NHTSA and forums hold large numbers of owner complaints. FCA began offering an optional Mopar Corning Gorilla Glass windshield as a more durable upgrade, though owners report even those can still crack.

The hardtop can leak water into the cabin, particularly around the rear window seals or the seal where the top meets the body. Freedom Panel leaks are covered separately. Water intrusion can wet carpets, seats, and cause electrical issues over time.

The two removable 'Freedom Panel' roof sections over the front seats on hardtop JL Wranglers commonly leak water — most often at the front edge near the windshield header and at the center seam between the panels — allowing water to drip onto the headliner, sun visors, dash and even the radio/center stack. Causes include pinched or misaligned panel seals, improper reinstallation after removing the panels, and seal degradation/shrinkage from UV exposure. It is a widespread, well-documented JL complaint (carried over from JK Freedom Tops) and, while a nuisance rather than a safety defect, can lead to interior water damage and electrical issues if it reaches the radio.

JK owners report factory soft tops leaking at the front corners and above the doors in heavy rain, and loud wind noise at speed where the top meets the windshield header. Owners report pinched or folded seals and a header that sits too high as causes. It affects only Jeep Wrangler and Wrangler Unlimited (JK) models with a soft top. Owner reports name 2008 and 2009 JKs.

NHTSA campaign 23V116000 covers certain 2018-2023 Jeep Wrangler vehicles equipped with manual transmissions. The clutch intermediate pressure plate may overheat and fracture, potentially cracking the transmission case and expelling heated debris. The debris may contact an ignition source and cause a fire; clutch odor, slippage or cluster messages may occur first.

The JL Wrangler with manual transmission can experience clutch issues including premature wear, judder, and difficulty engaging gears. Some owners report clutch failures at relatively low mileage, particularly with off-road or aggressive driving.

Wranglers equipped with the Mercedes-sourced NSG370 6-speed manual can develop hard shifting, grinding, and a tendency to jump out of first gear or other gears. Owners often describe the issue as worsening when cold, with synchronizer wear and internal shift component wear being common root causes. This problem is widely discussed in TJ/LJ communities and appears repeatedly in owner complaints and service literature.

JK Wranglers with the 42RLE 4-speed automatic exhibit a torque-converter-clutch (TCC) shudder felt as a steady-state vibration or shimmy, typically during light throttle/partial converter lockup and most noticeable when the transmission is at moderate operating temperature. Chrysler acknowledged the condition on 2007 JK Wranglers in TSB 21-001-08 Rev. B (February 2008), which addresses TCC shudder and shift-quality concerns (1-2, 2-3, 3-4 upshift bumps) and DTC P0732. The shudder stems from the converter clutch lining/fluid interaction and TCM calibration; left unaddressed it can progress to harsh shifts.

Some owners of JL-generation Wranglers (2018 onward) with the eight-speed automatic report harsh or jerky shifts, especially 1-2 and from a stop, and delayed engagement from Park into Drive or Reverse. It affects 2018-2025 Jeep Wrangler (JL) models with the eight-speed automatic. It does not apply to the 2007-2018 JK, which used four- or five-speed automatics.

The Dana 35 rear axle fitted to most non-Rubicon YJ/TJ Wranglers uses a C-clip design: each semi-float axle shaft is retained inside the housing only by a C-clip seated in the differential. If a shaft snaps — common with 33-inch-plus tires, a locker, or aggressive trail use — the wheel and outer shaft can slide completely out of the housing ("grenade"), damaging brakes and potentially separating the wheel while driving.

A distinct complaint pattern emerged in 2026 from 4xe owners who had already had Recall 68C / 25V741 performed. After the HV battery software reflash, electric-mode output is progressively cut back — first to roughly 50%, then 25%, then 'Electric Mode Temporarily Unavailable' — at battery states of charge as high as 41-81%, well above the point where the manufacturer's own specification says electric drive should continue. During the handover from electric to hybrid operation there is a delay of up to ten seconds in which the accelerator pedal produces nothing at all, followed in some cases by an abrupt surge when the gasoline engine catches. Multiple owners with prior 4xe experience (one with over 50,000 miles across two Wrangler 4xes) state explicitly that the vehicle behaved normally before the recall repair and would no longer climb minor hills in electric mode afterward. Reports cluster from December 2025 through July 2026.

The NP231 (Command-Trac) transfer case in YJ/TJ Wranglers uses a slip-yoke rear output. The rear output shaft seal is a chronic leak point — the exposed slip yoke picks up grit and rust that scores the seal, and a worn tail-housing bushing lets the yoke move and tear the seal. The result is ATF weeping from the back of the transfer case.

The in-tank fuel pump module (pump, sending unit, and level float) wears out on high-mileage TJ Wranglers, producing a loud whine from the tank, hard starting, stalling, and eventual crank-no-start as fuel pressure drops. It is sometimes accompanied by an inaccurate fuel gauge from the same module.

Many 2005-2006 TJ Wranglers develop a failed fuel tank inlet check valve that causes the gas pump nozzle to click off repeatedly or spit fuel back out of the filler neck. Owners report fuel spraying down the quarter panel or onto the ground near the end of fill-up, creating both inconvenience and fire risk. Chrysler did not recall the TJ for this; it issued service bulletin 14-001-09 REV A for refueling difficulties on 2005-06 TJ Wranglers.

The throttle-body-mounted TPS wears and produces an erratic voltage signal, causing high/hunting idle, stalling at stops, hesitation or bucking on acceleration, and — on automatics — erratic or harsh shifting. It is a very common TJ driveability complaint and often turns on the check-engine light.

Chrysler recalled 641 model year 2026 Jeep Wrangler and Gladiator vehicles because the wall thickness of the factory steel wheels is below specification. The thin walls can crack and, in the worst case, allow the wheel to separate from the vehicle, causing loss of control. This affects only trucks equipped with the factory steel wheels (sales code WAA) built November 10-16, 2025 — not the cast aluminum wheels fitted to Sahara and Rubicon. The remedy also covers valve stems, which suggests the affected wheels are being replaced as an assembly rather than reworked.

JK owners report front wheel hub bearings wearing out and needing replacement. On a 2016 Wrangler Unlimited Rubicon the ABS and traction-control lights went out only after the dealer replaced a bad left-front wheel bearing under warranty. On the JK the front wheel-speed sensor is part of the hub assembly, so a worn hub can also bring on the ABS light. It affects 2007-2018 Jeep Wrangler and Wrangler Unlimited (JK) models with any engine. The owner reports are from 2012 and 2016 JKs.

Rubicon owners report the electronic front sway-bar disconnect stopping working, with a flashing or missing indicator light, after water and corrosion get into the actuator's electrical connector or motor. One owner reports the corroded connector caused a battery drain, and another reports it brought on other warning lights at highway speed. It affects only Wrangler Rubicon and Wrangler Unlimited Rubicon (JK) models with the electronic front sway-bar disconnect; Sport and Sahara models do not have this system. The owner reports are from 2014 Rubicons, one of which had the problem at 67,000 km (about 41,600 miles).

Owners of 3.6L JK Wranglers report the electric radiator fan stopping, with code P0480 and the engine overheating at idle or low speed, especially in hot weather. The 3.6L fan has its controller built into the fan assembly and runs on a power feed from the battery plus a control signal from the fuse and relay module (TIPM), so the cause can be the fan, its power or ground connection, or the signal. It affects 2012-2018 Wrangler and Wrangler Unlimited (JK) models with the 3.6L Pentastar V6; owner reports name a 2015 JK Unlimited and other 3.6L JKs.

The 2.0L turbocharged four-cylinder (GME-T4) is prone to recurring low-coolant warnings and external coolant leaks. Heat radiating off the turbocharger embrittles the plastic coolant 'Y' fitting and the coolant overflow/recovery reservoir, causing them to crack and weep. Separately, Stellantis issued a customer satisfaction notification for 2021-2022 2.0L JLs covering coolant seepage from the coolant inlet tube fasteners, with the fix being removal of the fasteners, application of thread sealant, and reinstallation. Owners report having to repeatedly top off the recovery bottle. If a coolant leak migrates internally it can contaminate the oil and eventually damage bearings, so persistent low-coolant should be diagnosed promptly.

The TJ/LJ Wrangler commonly develops coolant leaks from the plastic radiator end tanks, especially near the upper hose neck or crimp seam. Heat cycling and age make the plastic brittle, and owners often first notice a sweet smell, dried coolant residue, or overheating in traffic or on trails. This is one of the most frequently discussed age-related failures on 2000-2006 Wranglers.

The heater core inside the dash-mounted HVAC box develops leaks on high-mileage Wranglers, releasing a sweet coolant smell in the cabin, an oily film that fogs the windshield, and eventually a wet passenger-side carpet with unexplained coolant loss. The repair is labor-intensive.

JK owners report a clicking from behind the dash and heat or air conditioning stuck at one temperature, sometimes with a blinking light on the climate control. Owners trace it to the blend-door actuator, whose small plastic gears break so the motor jumps teeth instead of moving the door. It affects 2007-2018 Jeep Wrangler and Wrangler Unlimited (JK) models. Owner reports name 2011, 2012 and 2013 JKs; in those reports it happened at 14,500 miles on a 2012 and 44,000 miles on a 2011.

Owners of high-mileage 3.8L JK Wranglers report code P0430 (catalyst efficiency, bank 2, the driver side) from a worn catalytic converter, sometimes with P0420 for the other side. An exhaust leak ahead of the converter or a faulty oxygen sensor can set the same code. It affects 2007-2011 Jeep Wrangler and Wrangler Unlimited (JK) models with the 3.8L V6.

JK owners report check-engine lights for evaporative-system leaks (P0455, P0456) that a new gas cap did not fix. Owners report the leak at the small white leak-detection module and its seal on the black charcoal canister, the canister's fresh-air filter or check valve, or a plastic vapor line on top of the tank. The fault affects emissions testing, not how the Jeep drives. It affects 2007-2018 Jeep Wrangler and Wrangler Unlimited (JK) models with any engine.
