2019 RAM 1500 Problems: 34 Known Issues

How to Fix

For prevention: Use quality synthetic oil and change every 5,000 miles. Install an MDS delete kit ($200-400) to prevent future failures. If lifters have failed: Full lifter replacement with non-MDS lifters ($2,000-3,500). If camshaft is damaged, expect $3,500-5,500 for full repair. Consider a tuner to disable MDS electronically.

Owner tips & cautions

• TipDIY repairs can save significantly - dealer charges $200-400 but DIY costs are typically 50-70% less
• TipInstall an MDS delete kit ($200-400) to prevent future failures.
• WarningThis is a high-severity issue - ignoring it can lead to costly repairs or safety concerns. Address it promptly.

How to Fix

Have a qualified technician diagnose the misfire, rough idle or valvetrain noise and verify the engine/build scope in 09-011-25. For the confirmed intake cam/rocker wear described, use the bank-specific intake camshaft service kit instead of replacing the complete engine or long block. The kit includes the intake cam, rocker arms, sealer and gaskets; only the camshaft is illustrated here. The bulletin lists right-intake kit 68661147AB and left-intake kit 68661146AA; confirm current supersession and VIN fitment before ordering. Do not infer an exhaust-cam repair, failed roller bearing or universal failure rate from this image. Normal warranty eligibility must be checked separately.

How to Fix

Have persistent ticking or misfire checked by a qualified engine shop or Ram dealer and distinguish exhaust-manifold noise from an internal valvetrain concern. If inspection confirms cam/lifter damage, repair the diagnosed components and assess whether debris has caused additional damage before choosing the repair scope. Owners describe camshaft/lifter replacement and, in a separate more extensive damage report, engine replacement; neither is the default for every tick, and one repair account remained unresolved. The illustration is not a complete parts kit. Keep maintenance and diagnosis records, confirm current engine-specific parts and warranty terms, and do not infer an MDS-delete, different oil viscosity or universal engine replacement from forum speculation.

How to Fix

Replace broken bolts with upgraded stainless steel manifold bolts ($50-100 for kit). If studs break off in the head, extraction may be needed ($200-500 at shop). Some owners upgrade to headers which eliminates the issue entirely ($800-2,000). Apply anti-seize to new bolts during installation.

Owner tips & cautions

• TipDIY repairs can save significantly - dealer charges $50-100 but DIY costs are typically 50-70% less
• TipGet a proper diagnosis before replacing parts - similar symptoms can have different causes
• TipSearch RAM 1500 forums and owner groups for real-world experiences and DIY guides
• TipGet multiple quotes from independent mechanics - dealer prices can be 2-3x higher for the same repair

How to Fix

Start with the cheap, high-yield steps: verify oil level and do a fresh oil-and-filter change using correct-viscosity oil (5W-20 on the Hemi), then clear the code and retest — dirty/degraded oil is the single most common trigger. If P0011 returns, replace the VVT/oil-control solenoid (clean the screen or renew), and perform the required cam/crank relearn afterward. If codes persist after a new solenoid, or the engine ticks and has high mileage, inspect the cam phaser, timing chain/guides and — critically on the Hemi — the camshaft lobes and lifters (MDS lifters), since VVT timing codes frequently accompany the cam/lifter failure. On the 3.6 Pentastar, also confirm the oil-filter-housing/cooler is not leaking and starving oil pressure.

How to Fix

Have a Ram dealer check the VIN and complete outstanding 24V653/75B with the ABS control-module software update, free of charge. Confirm the campaign and completion on the repair order. The recall report does not prescribe replacement of the ABS module, wheel bearing or encoder ring, and it lists no diagnostic trouble-code requirement. If symptoms remain, have them diagnosed separately rather than using unsupported C2200, C2116 or U0121 rules to choose hardware. Preserve the separate 2025-only 24V794 campaign distinction; do not schedule both campaigns as if their documented year populations overlap. Do not intentionally test stability-control loss on the road.

How to Fix

Scan and confirm the module codes. For C2116/C2200 internal faults, the EBCM/ABS module is replaced (or sent for bench repair) and then programmed to the truck's VIN. Always check first whether the truck is covered by an active ABS-related recall or software TSB, which may fix the symptom for free. Verify proper brake-pedal feel and warning-light clearance after repair.

How to Fix

Ask a Ram dealer to check VIN eligibility and carry out ZB8 free of charge when outstanding. First check for tonneau-cover, equipment or debris interference and test tailgate operation using the prescribed stationary procedure. If operation is correct, inspection alone completes the repair. If binding remains, adjust both strikers to center them vertically in the latch openings and adjust fore/aft for easy closing; eliminating binding takes priority over panel flushness. For the DT 1500 the procedure specifies 49 N·m (36 ft-lb) striker tightening, followed by repeat operation checks; the 2500/3500 torque differs. No replacement parts are required. Confirm secure latching after closing because a binding tonneau cover can give a false impression that the tailgate is latched. This is dealer recall guidance, not an instruction to drive with the gate unsecured.

How to Fix

Have the dealer perform Recall 26V495 (FCA 67D) — inspection and, where required, attachment of the second-row seat belt buckle anchor to the body structure, free of charge. Because the defect is a missing attachment rather than a broken part, it is invisible from the cabin; do not try to self-assess by tugging on the buckle. Until the inspection is done, prefer the front seats for passengers where practical and be aware that a child seat secured by the second-row seat belt rather than by the lower LATCH anchors depends on this attachment.

How to Fix

Diagnose with wiTECH to read air suspension fault codes and check height sensor readings. Leak test each air spring with soapy water at all seams and fittings. Ask the dealer to check bulletins S1902000008, S2208000197 and the 0812723 air suspension control module flash against your VIN. Replace leaking air springs ($300-600 each, OEM Mopar 68364461AA for rear). If compressor is burned out, replace with an OEM or quality aftermarket compressor listed for the 2019+ truck ($800-1,500). Some owners convert to traditional coil springs using a conversion kit ($800-1,200 for all four corners) to eliminate the air suspension entirely.

How to Fix

Have a qualified suspension shop or Ram dealer diagnose the warning and check the lines and fittings for leaks before choosing a repair. Compressor replacement was an owner-reported outcome, not a proven cure in every report; do not order an assembly solely because the truck is low. STAR case S1902000008 Rev. A warns technicians to leave the specified plastic fitting on the compressor assembly in place because removing it can cause an internal nitrogen leak. Follow the service procedure for line handling and the diagnosed repair. This STAR note records prior service experience, does not identify the cause on your truck and does not authorize warranty repairs. Do not apply an engine belt-generator replacement to the separate electric suspension system.

How to Fix

Diagnose for air-bag leaks first (soapy-water test on bags/fittings) before condemning the compressor, since a leaking bag is the usual root cause of compressor burnout. Replace leaking air spring(s), then the compressor/dryer assembly if it has failed. On 2023 trucks, apply TSB 08-152-24 (air suspension control module reflash) for false 'stuck sensor' faults; on other years ask the dealer for the current air suspension software update. Some owners convert to a conventional coil-spring kit to eliminate the system. Dealer compressor replacement is often ~$2,500-$3,300; DIY parts can be far less.

How to Fix

The remedy is a free software flash of the engine or powertrain control module, performed by a RAM dealer after inspecting the existing software. Have the dealer confirm VIN eligibility and campaign completion history; other faults may require separate diagnosis. Until it is confirmed complete, do not use cruise control. If cruise cannot be shut off while driving, apply the brakes firmly and steadily, shift into neutral, and put the truck in park once stopped. Chrysler customer service: 1-800-853-1403.

How to Fix

First try a Uconnect software update and a hard reset (press and hold the volume/tuner controls; or a documented fuse-pull reset letting the unit sit so internal capacitors discharge). If the panel shows vertical lines or stays black after software steps, the display/head-unit assembly is replaced. Replacement units must be programmed; check for any active warranty/extended-coverage or software TSB before paying for a full radio.

How to Fix

Perform a Uconnect soft reset (key to RUN, then hold the volume knob and tuner knob together ~10-20 seconds) to clear a frozen screen. Have the dealer install the latest Uconnect software (per TSB 08-003-19) which addresses many freeze/reboot/camera cases. Persistent hardware faults (de-lamination, ghosting, dead camera image) require radio or camera replacement, ideally under the basic (bumper-to-bumper) warranty.

How to Fix

If assist is lost, prioritize getting safely stopped and arrange qualified diagnosis rather than deliberately repeating the fault. Have the steering system, electrical supply and connections checked before ordering parts. One owner reports rack-and-pinion replacement after connector corrosion was identified; that is an individual repair outcome, not proof that every warning needs a rack. Repair the diagnosed connection or component according to the vehicle service procedure and verify assist operation. Check outstanding campaigns by VIN separately; do not apply the older DS recall or the unrelated low-speed-right-turn software bulletin solely because this warning appears.

How to Fix

A qualified technician should check for other faults first, then update EPS software under 08-137-21 Rev. B when the symptom and build scope match, and clear reprogramming-related DTCs. Use the specified battery support throughout the flash. The bulletin warns that an aborted or failed flash can leave an unexpected EPS part number that cannot be reflashed and requires EPS replacement; this exception is not a recommendation to replace the rack for every noise complaint. Normal warranty provisions apply.

How to Fix

Check the VIN for 19V757 / VB1 and have the dealer replace the EGR cooler and inspect or replace the intake manifold as necessary, free of charge. If coolant loss, smoke, a burning odor or fire occurs, stop safely, shut down, exit and call emergency services when needed.

How to Fix

Confirm the cold-start noise and inspect the suspect manifold after the specified heat-shield removal. Replace only the manifold side or sides confirmed cracked, using the complete kit: manifold, gasket, all new fasteners, heat shield and tie bar. The tie bar is required even when none was fitted before. The bulletin says fasteners were lengthened 6 mm with the tie bar; the right-side front-most fastener is 5 mm shorter than the others. Follow the exact service procedure and confirm side-specific current parts by VIN: the 2024 table repeats one part number for both sides, while the superseded 2022 bulletin lists different left/right numbers. Do not infer a shopping fitment from that inconsistency or substitute generic upgraded studs. Normal warranty provisions apply; this is not a recall or a promise of free repair.

How to Fix

Check the VIN with a Ram dealer or NHTSA recalls. For an outstanding applicable recall, dealers replace the high-pressure fuel pump with the improved-durability remedy and inspect, and if necessary replace, additional fuel-system components free of charge. The pictured pump is not the whole repair kit and does not establish current part fitment. A pump-only repair may be incomplete when debris has contaminated other components. Keep receipts for a prior repair and ask about the documented reimbursement process. Do not deliberately reproduce a stall on the road or infer P0087 from these reports; they do not list diagnostic codes.

How to Fix

Confirm the leak is at the CHMSL and follow bulletin 23-074-23 to replace the complete lamp assembly; the listed bulb-CHMSL assembly is 68298380AH, with current fitment verified by VIN. Ensure the interior is dry before returning the truck. This is not a universal butyl or added-foam repair, and it does not repair a separate rear-window or antenna leak. Check remaining XG1 time/mileage and regional eligibility; do not promise free repair solely from the model year.

How to Fix

Check the upper sliding-window frame corners and confirm the backlite is the leak source, then follow 23-098-23 to replace the qualified backlite assembly. Select the correct manual/power and regional kit by VIN; the North America-only kits and other listed assemblies are alternatives, not interchangeable purchases. The bulletin lists two 04864015AD glass adhesive installation kits and permits equivalent urethane/primer when Mopar materials are unavailable; follow the exact installation procedure and cure requirements. Ensure the interior is dry before returning the vehicle. A bead of sealant over the crack is not the specified repair. Check remaining XL1 time/mileage eligibility rather than promising a free repair from the model year.

How to Fix

Photograph the damage and document any earlier paint, wrap or repair work before altering the surface. Ask a qualified body shop to distinguish coating separation, clear-coat defects and impact chips, then recommend the appropriate localized finish repair or refinishing. The image shows a possible refinished surface, not a required replacement bumper. If seeking coverage, ask a Ram dealer to inspect it before repainting; the reports include disputed causes and do not establish automatic warranty eligibility. Forum suggestions about wet-sanding, ceramic coating or paint-protection film are not a manufacturer-approved cure for the reported damage.

How to Fix

Have a qualified shop check latch operation, striker clearance and electrical connections for the exact tailgate equipment. STAR S1823000056 Rev. E describes a striker binding on the top or bottom of the latch opening: when confirmed, center and adjust it using the applicable current service procedure. Its ajar-light test says not to replace a latch if the indication clears; otherwise check the electrical connection, and replace the right latch only if the prescribed test still fails. Do not force a stuck gate or infer a failed solenoid from a click. Separately check VIN eligibility for 22V904/ZB8; its equipment exclusions and DT torque differ from the older STAR note, so use the applicable current procedure rather than mixing them. The 2021 split-gate snippet requires separate diagnosis, and neither owner accounts nor the STAR note promise warranty coverage.

How to Fix

First step: Get latest transmission software update from dealer (often free). Change transmission fluid and filter every 60,000 miles using ZF Lifeguard 8 fluid only. If problems persist, valve body replacement may be needed ($1,500-2,500). Full transmission replacement runs $4,000-6,500.

Owner tips & cautions

• TipDIY repairs can save significantly - dealer charges $1,500-2,500 but DIY costs are typically 50-70% less
• TipGet a proper diagnosis before replacing parts - similar symptoms can have different causes
• TipSearch RAM 1500 forums and owner groups for real-world experiences and DIY guides
• TipGet multiple quotes from independent mechanics - dealer prices can be 2-3x higher for the same repair

How to Fix

First request all available TCM/transmission software updates (multiple TSBs/reflashes exist). A full fluid-and-filter service with the correct ZF spec fluid resolves a large share of early shudder cases. Persistent shudder after fluid/software typically requires torque-converter replacement or rebuild. Stellantis specifies long fluid intervals, but many owners service the fluid by ~60k miles preventively.

How to Fix

Verify the transfer-case sales code, build date, symptoms and DTCs against 08-144-22. Diagnose other faults first. If only C1403 is present, use normal diagnosis before a flash; the same caution applies to the isolated Service 4WD or dual-blinking-indicator conditions described for 2019–2020. When qualified, reprogram the DTCM with current software using the specified battery support, then clear reprogramming DTCs. This procedure does not prescribe replacement of the shift motor, transfer case or generic module shown. Normal warranty provisions apply.

How to Fix

Replace the pinion seal using a new crush spacer (collapsible) and torque the pinion nut to spec to set proper bearing preload; using thread-locking adhesive on the nut helps prevent re-leaks. If a whine is already present, the pinion bearing and ring-and-pinion may need inspection/replacement and a re-shim. Verify gear-oil level and use the correct spec fluid (with friction modifier for limited-slip).

How to Fix

Before replacing the catalytic converter, inspect for exhaust manifold cracks/broken bolts and test the upstream and downstream O2 sensors; check for any PCM software update addressing catalyst-monitor sensitivity. Repair manifold leaks and replace a lazy downstream O2 sensor first. Only replace the catalytic converter once leaks and sensors are confirmed good. Address any underlying rich-running cause (MAF, fuel trim) so a new cat is not damaged.

How to Fix

Have a qualified shop read the code and follow the vehicle EVAP diagnostic procedure before buying a filler assembly or purge valve. Bulletin 18-048-23 requires the wiTECH Small Leak Verification Test first to verify a leak, then again after component repair or replacement to confirm the fix; it explicitly includes PCM software updates for P0456. Repair the identified cause rather than assuming the pictured filler is faulty. A road test alone will not confirm this repair. The bulletin is information-only and does not promise warranty coverage; confirm any applicable emissions coverage for the diagnosed part and vehicle separately.

How to Fix

Have the system leak-tested (UV dye or electronic sniffer) to confirm the condenser as the source versus a hose, O-ring or compressor. If the truck is still under the basic warranty, ask the dealer to replace a leaking condenser under warranty; otherwise replace the condenser (Mopar part number 68322495AB or 68312697AC for 2019-2024 DT trucks; confirm which one fits your truck by VIN), evacuate and recharge the system, and verify with a pressure/leak test. Add a condenser guard if impact damage is a concern.

How to Fix

Have a qualified HVAC technician read the climate-system codes and verify whether STAR S2124000003 applies. Test the driver blend-door actuator resistance using the pin, temperature and resistance table: replace the actuator if out of specification, then continue the remaining checks. Inspect beneath the HVAC case for water or coolant intrusion; the note also calls for actuator replacement when those marks are found. Inspect the drain with a borescope, clear any blockage and investigate water entry, heater-coolant leaks or misplaced seals. When there is no intrusion evidence, calibrate the actuator and confirm that driver-side temperature changes from cold to hot. A replacement alone did not cure one owner report. This STAR note records service experience and does not authorize warranty repairs; confirm exact replacement fitment when inspection justifies it.

How to Fix

Have a qualified shop perform the service-manual pressurized cooling-system inspection and UV leak check before replacing parts, as described in STAR S2307000002. Check all relevant hoses, connections, radiator, reservoir, thermostat, front cover and other cooling components; inspect above any low-mounted residue. The note says some residue at the water-pump weep-hole plug can be normal, but coolant should not be dripping there. When the pump is confirmed as the source, replace the correctly fitted pump and required sealing materials, restore the specified coolant using the vehicle service procedure, and verify the repair. An owner also changed the belt and thermostat, but that individual choice is not a universal parts list. The STAR note does not authorize warranty repairs; do not open a hot pressurized cooling system.

How to Fix

Photograph the affected area and have a qualified interior-trim shop or Ram dealer assess whether the leather covering has separated or a removable trim panel has lifted. A 2019 owner reports that Ram replaced the dashboard under warranty; another received a quote to replace dash parts. Use replacement trim when the inspection supports it, with exact color, equipment and part fitment confirmed before ordering. These are owner-reported outcomes, not a universal manufacturer procedure or promise of coverage. The separate 2020 lifted-corner thread contains conflicting suggestions about replacement and reshaping; it does not establish that the entire dashboard must be replaced. Do not treat forum glue or heat-gun suggestions as an approved procedure.
