TIRES:PRESSURE MONITORING AND REGULATING SYSTEMS
Chrysler (FCA US, LLC) is recalling certain 2024-2025 Jeep Wrangler vehicles. The remote start antenna cable may be pinched, which can cause the tire pressure monitoring system (TPMS) warning light not to illuminate as intended. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 138, "Tire Pressure Monitoring Systems."
ELECTRICAL SYSTEM:PROPULSION SYSTEM:TRACTION BATTERY
Chrysler (FCA US, LLC) is recalling certain 2020-2025 Jeep Wrangler 4Xe and 2022-2026 Grand Cherokee 4Xe vehicles. The high voltage battery may fail internally and lead to a vehicle fire while parked or driving.

The 2018 Jeep Wrangler has 37 known issues documented across 6,731+ owner reports. 9 issues are rated critical: Steering Stabilizer Failure/Death Wobble and Manual transmission clutch pressure plate overheating / fire risk (recall 21V-028 & 23V-116) and TIPM (Totally Integrated Power Module) failure — fuel pump relay & random electrical faults and eTorque Belt-Starter Generator (BSG) / 48V Power Pack Failure — Charging & No-Start and Death Wobble: violent front-end shaking at highway speed (solid front axle) and Cruise Control May Not Disengage — Wiring Short Circuit (Recall 18V332000) and Steering Gear Box Loose Play & Highway Wandering (Aluminum-to-Steel Box TSB) and 3.6L Pentastar Rocker Arm / Lifter Needle-Bearing Failure — Valvetrain Tick, Misfire & Cam Damage and Powertrain Control Module Voltage Regulator Chip Failure — Stall or No-Start (Recall 18V524000 / Chrysler U87). Prospective buyers should inspect for these issues and factor potential repair costs into their purchase decision. Regular maintenance following the manufacturer's schedule helps prevent many common problems.
Repair costs for known Jeep Wrangler issues range from $0 to $4,000, depending on the specific problem and whether you choose DIY or professional repair. The most critical issue, Steering Stabilizer Failure/Death Wobble, typically costs $100-$2,000 to repair. Au7o provides step-by-step DIY maintenance guides that can help reduce repair costs.
A worn steering stabilizer combined with other suspension wear can contribute to 'death wobble' - a violent shaking of the front end at highway speeds, usually triggered by a bump. While the stabilizer alone rarely causes death wobble, it can mask other issues. Repairs typically run $100-$2,000. Severity: high.
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 ignitio… Severity: high.
The TIPM is the integrated fuse/relay power-distribution module controlling most electrical systems. On many 2007-2018 Chrysler/Jeep vehicles, including the JK Wrangler, the internal fuel-pump relay (and later the other relays) degrades. The first symptom is usually a fuel-pump-r… Repairs typically run $100-$1,200. Severity: high.
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-sta… Repairs typically run $0-$3,000. Severity: high.
Wranglers (JK and JL) with a solid front axle are prone to 'death wobble' — a violent, self-reinforcing side-to-side oscillation of the front-end steering components and steering wheel, typically triggered by hitting a bump, expansion joint or pothole at speeds above ~45-55 mph. Repairs typically run $150-$1,200. Severity: high.
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 a… Severity: high.
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 itse… Repairs typically run $0-$1,200. Severity: high.
The 3.6L Pentastar V6 used in JK (2012-2018) and JL (2018+) Wranglers suffers a documented valvetrain failure separate from the engine's oil-consumption problem. The needle roller bearings inside the rocker arms wear prematurely, loosen, and can drop out, shifting the rocker arm… Repairs typically run $1,300-$4,000. Severity: high.
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… Severity: high.
Lifted Wranglers commonly experience driveshaft vibration due to changed driveline angles. Even stock Wranglers can have premature U-joint wear. The double-cardan front shaft is particularly prone to issues. Repairs typically run $200-$1,500. Severity: medium.
The 3.6L Pentastar V6 can consume oil at a rate higher than expected, sometimes requiring oil top-ups between changes. This is often related to piston ring design or valve guide seals. Chrysler considers up to 1 quart per 2,000 miles as within normal range. Repairs typically run $0-$3,500. Severity: medium.
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. Repairs typically run $800-$2,500. Severity: medium.
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… Severity: medium.
On JK-generation Wranglers the exhaust manifolds and their gaskets are a well-known weak point, and when the driver-side (bank 2) manifold develops a hairline crack or the gasket at the head or the manifold-to-downpipe joint starts leaking, the leak sits directly upstream of the… Repairs typically run $450-$1,500. Severity: medium.
On the Jeep Wrangler JK/JL, P0430 almost always points to a worn-out catalytic converter on the driver's side (Bank 2 is the driver side on the Jeep V6 — the reverse of many V-engines). The catalyst monitor compares the upstream and downstream oxygen sensors; as the converter's o… Repairs typically run $300-$1,500. Severity: medium.
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 regist… Repairs typically run $150-$1,200. Severity: medium.
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. Separate… Repairs typically run $120-$600. Severity: medium.
The 3.6L Pentastar's combined oil cooler and oil filter housing adapter sits in the engine valley and is made of plastic that hardens, warps, and cracks under sustained underhood heat — it can also crack from over-tightening the oil filter cap. The resulting oil (and sometimes co… Repairs typically run $150-$700. Severity: medium.
The 3.6L Pentastar JK uses a single electric radiator fan driven by a pulse-width-modulated (PWM) duty-cycle signal from the TIPM rather than a simple on/off relay. The integrated fan motor/controller fails, or the PWM signal circuit faults, so the fan won't spin up at speed — ca… Repairs typically run $150-$700. Severity: medium.
JK Wranglers use a drive-by-wire electronic throttle. A fault in the electronic throttle body, the integrated throttle position sensor (TPS), the accelerator pedal position (APP) sensor, or their wiring/connectors triggers the red lightning-bolt warning, often together with the t… Repairs typically run $50-$450. Severity: medium.
