2022 Jeep Wagoneer electrical problems

The eTorque hybrid-electric system and 48V auxiliary battery fail to hold charge or supply power, causing the engine to stall at intersections, traffic lights, or while accelerating. Owners report the vehicle shuts off mid-drive, requiring restart; some incidents occur on highways at speed. Multiple owners describe repeated trips to dealers where battery replacement is attempted but does not resolve the root cause. One owner's vehicle was stuck in a shop from mid-November 2024 into January 2025, with the shop unable to identify the fault.

When: Occurs within first few months to years of ownership; one instance reported at 25,000 miles, another at 100+ miles after purchase; recurring across multiple seasons

Symptoms owners cite: Engine stalls at stop lights, intersections, or while driving at various speeds; Battery and check engine lights illuminate; Start/Stop Unavailable warning message; Vehicle requires restart by pressing ignition button; Loss of power steering and braking ability (in severe cases); All dash gauges may read normally after restart despite prior shutdown

Codes mentioned: U0485, Check engine light, Battery warning light

Repairs/costs cited: Dealers have replaced the 48V auxiliary battery multiple times; some attempt software updates; one shop replaced the ECM and eTorque-related components with no lasting fix. One owner reported 168-day backorder for an alternator; another reports the auxiliary battery is no longer manufactured in the US, making replacement difficult.

Recalls/TSBs owners mention: Technical Service Bulletins exist (U0485-00 referenced); NHTSA Investigation PE24018 is open. Dealer service bulletins mention eTorque/hybrid battery issues since 2021 model year. One owner was told the issue was due to the 'sideboard' but shop could not guarantee a fix. Chrysler/Stellantis has not issued a recall despite 'hundreds' of complaints reported to at least one owner.

Vehicle unexpectedly cuts power while in motion, disabling steering, brakes, and engine. Engine shuts off and may not restart immediately. Some owners describe the vehicle shifting into Park on its own. Extremely dangerous events occurring at intersections, on highways, and in heavy traffic. One owner was rear-ended after the vehicle shut down. Multiple owners report this as a repeat failure despite attempted repairs.

When: Can occur early in ownership (one instance at 10 days post-purchase); recurring across multiple incidents spanning months or years

Symptoms owners cite: Complete loss of electrical power while driving; Engine shuts off mid-motion; Loss of power steering; Loss of power brakes; Vehicle shifts into Park without driver input; Emergency brake engages on its own; Multiple warning lights and error messages appear on dash (e.g., brake service, shift to P, stop/start restart required, battery warning, check engine light); Dashboard and infotainment screen go dark for 10+ minutes before rebooting; Vehicle will not restart or is difficult to restart; requires jump-start or extended waiting period

Codes mentioned: Check engine light, Battery warning light, ABS light, Brake service warning, ESS/Start-Stop system malfunction

Repairs/costs cited: Dealers claim no codes are retrieved or failure cannot be duplicated, resulting in no repair. Some owners report the dealership re-charged the battery and sent vehicle home without investigation. One repair attempted replacement of the throttle module 'as a guess' without code confirmation. Another owner had the Body Control Module replaced after month-long repair.

Recalls/TSBs owners mention: Chrysler corporate has acknowledged open cases; some owners cite open NHTSA investigations. One owner requested escalation to a Stellantis Case Manager. No systematic fix has been provided; dealers are instructed to perform software updates with no guaranteed resolution.

Vehicle loses throttle response while driving; engine runs but car will not move. Red lightning bolt warning flashes on dash with messages such as 'service electronic throttle control' and 'service electronic stability control.' Vehicle may be stranded until turned off and restarted. One instance occurred on a mountainous highway at speed; another mid-intersection. Failures have recurred despite multiple repair attempts.

When: Failures begin at approximately 30,000 miles; incidents reported as close as 319 miles apart; recurrence despite multiple repairs

Symptoms owners cite: Random loss of throttle power while driving; Engine continues to run but vehicle will not move forward or backward; Red lightning bolt warning icon on dash; Service electronic throttle control warning message; Service electronic stability control warning message; Service stop/start system warning; Check engine light illuminates; Warning beep precedes the failure

Codes mentioned: Check engine light, Electronic throttle control fault, Electronic stability control fault, Stop/start system fault

Repairs/costs cited: Dealers have attempted repair 4–5 times at multiple dealerships. One dealer proposed replacing the throttle module 'as a guess' with no diagnostic codes to support the repair. Owner states dealers acknowledge there are no codes pointing to the suspected part.

Recalls/TSBs owners mention: Dealers have not taken the issue seriously despite multiple occurrences. One owner states customer care agents are aware but have not grasped the gravity of the safety hazard.

Vehicle cuts ignition and shifts itself into Park without driver input, often during normal driving or at stops. Engine restarts only by pressing the ignition button.

Radio, GPS, navigation screen, and infotainment system randomly shut off, fail to boot, or display error messages. Failed software updates can disable vehicle functions like high-beam headlights, auto-locking doors at speed, emergency pedestrian braking, and gauge displays. Language and measurement units change without driver input. Screen reboots during drives. One update in Fall 2024 caused widespread issues across multiple owners; dealership software resets do not fully resolve the problems.

Recalls/TSBs owners mention: Jeep customer service has confirmed software is up to date and stated they have no remedy in place. One owner reports Jeep is 'aware of' the Fall 2024 update issue and that dealerships are 'scratching their heads.' Multiple owners report seeing many other Wagoneer owners on forums experiencing identical issues after the Fall 2024 update. No recall or universal fix has been issued.

Repairs/costs cited: Dealership recommended cleaning sensors, which did not resolve the issue. Multiple repair attempts across two dealerships over 30+ days have been unsuccessful.

Recalls/TSBs owners mention: Unknown sensor replacement was attempted but failure recurred. Dealer advised owner to seek repair at a different dealership; manufacturer instructed owner to take vehicle to a different dealer with no further assistance provided.

Power steering system fails or warning appears and then goes away intermittently. Braking system fails completely or locks up sporadically. Loss of both steering and braking simultaneously while driving on an interstate, requiring emergency pull-off. One instance involved brake booster failure.
