Electrical System Problems of Jeep Wagoneer - part 1

Vehicle information: 2022 Jeep Wagoneer (5. 7l v8 etorque mild-hybrid system)component affected: electrical system / hybrid propulsion system defect: my 2022 Jeep Wagoneer continuously experiences sudden engine stalling and unexpected shutdowns while operating in auto start-stop mode. When the vehicle comes to a complete stop at a red light or intersection, the engine shuts off normally to save fuel. However, when I release the brake pedal to accelerate, the vehicle fails to restart automatically. Instead, the vehicle suffers a total loss of power, drops the transmission directly into park (p), and abruptly engages the emergency parking brake. This creates an immediate, severe safety hazard as it leaves me completely stranded in active traffic and at busy intersections. To get moving again, I am forced to completely cycle the push-button ignition manually. Additionally, the vehicle regularly fails to remote-start, turning itself off immediately due to the electrical fault. A diagnostic scan reveals dtc p0b42 (hybrid/ev battery voltage sense "b" circuit low). This dangerous stalling pattern directly matches the active federal probe under NHTSA investigation pe24018 regarding 2022 Jeep Wagoneer 48-volt electrical and power distribution failures.

Pulling from a stop sign across two lanes of traffic into a median, the car shut off and then started back. When it started back there were multiple warning lights. Pulled out onto highway and when coming to the next turn, there were no power brakes. Had to use extreme pressure to slow the vehicle down to a stop. Turned the car off and then back on and most lights went off.

Vehicle began to randomly shut off at low speed while moving, while stopped and also in park. Has not yet happened at high speeds. All occasions are at speeds of less than 5 mph, no mil. Took to the dealership, diag of faulted aux battery. Battery replaced. Still very randomly will die in gear, at low to no speed, and also in park on occasion. Dealership update software of the bcm, pcm, and dcm. Returned to us with the same ongoing dying issue, returned to dealership, they did a wheel alignment, obviously didn't fix the dying issue. This vehicle carries my family, this will cause an accident as other traffic avoiding the vehicle has been the only factor in avoiding accident. No codes present. Vehicle is being refused to drive due to the uncertainty of when and where the vehicle will die randomly. This has happened numerous times over the last month, we will not accept the return of this vehicle until this problem is solved. This has so far only happened at low speed. Dealership has put many highway miles on it without replicating issue. It can be easily replicated by merely driving it from one parking spot to another or around a parking lot stopping and starting and traveling at speeds 5mph or less. This will happen at low to no throttle input. Vehicle will immediately start and run after being placed into park and hitting the start button, this is not the auto -start-stop feature working correctly. Dealership states this has only happened while pulling into a working bay at the dealership, unable to replicate results on the highway. It is currently the low speed dying that is the issue, this has been brought to the attention of the service dept on numerous occasions.

The vehicle has not started, on 2 separate occasions. It will not start, let you open the door and, the app won't work. It is just dead. After a period of time, it will start and work fine. Then it won't start again. I have read there are several instances on your web site of this type of failure. The dealer can't find anything "wrong".

Vehicle lost eng power would not restart had to be towed to dealership they conformed problem.

While merging onto the interstate with my wife and kids in the car, the car engine stopped nearly causing a dangerous accident. Got it to a dealership and the etourque system needs a 4200 repair and I believe there is an investigation into this problem with Jeep.

While driving on the highway going 70 mph, the vehicle lost all power and shut down engaging the automatic emergency brake system. This is the second time it has happened. Car is currently at dealership awaiting service.

I purchased my 2023 Jeep Wagoneer new in March 2023. The vehicle has experienced multiple electrical/electronic safety-related failures. Beginning around oct. 2024, the digital instrument cluster intermittently failed to load after startup, leaving me without critical information including vehicle speed and fuel level. I photographed this occurring numerous times and repeatedly reported it to the dealer. The cluster was eventually replaced in April 2026. The vehicle has also unexpectedly shut off more than once while slowing or coming to a stop at a stop sign or traffic light. In July 2026, the entire right-front exterior lighting system failed. The right headlight, daytime/running light, front turn signal and cornering light are all inoperative while the left side operates normally. The dealer replaced the complete right headlamp assembly in Aug. 2026, but this did not correct the problem. All right-front lighting remains inoperative. The odometer is also continuously flashing. The dealer has not determined the cause and says further diagnosis and stellantis star technical assistance are required. As of sept. 2026, the lighting failure has persisted for more than a month despite a repair attempt. I am concerned about the safety risks from loss of required exterior lighting/turn-signal function, prior loss of instrument-cluster information, and unexpected vehicle shutoffs. I do not know whether these conditions share the same underlying cause.

While driving down the road, I came to a stop and the vehicle started flashing every light then would not restart or allow the vehicle to be put into neutral. Initially thought maybe a battery issue despite my new battery being only eight months old replaced the battery and all the electronics started going haywire requiring the vehicle to be towed.

While driving my 2022 Jeep Wagoneer at 40-45 mph on a live public road with my four small children in the vehicle, the vehicle suffered a sudden, catastrophic electronic and powertrain shutdown without warning. The engine completely died, and the vehicle immediately and forcefully engaged the electronic emergency parking brake, bringing the vehicle to an abrupt, unexpected halt in the middle of moving traffic. Once stopped, the vehicle completely refused to crank or restart. The electronic shifter and braking system effectively locked the vehicle in place, leaving me and my four young children dangerously stranded inside a dead vehicle in the middle of a live lane, creating an immediate, life-threatening collision hazard from oncoming traffic. The vehicle had to be physically towed away from the scene to a dealership, where it currently sits awaiting diagnosis. This vehicle has a documented history of prior electronic and dashboard glitches that the manufacturer has failed to permanently resolve under warranty. The sudden loss of propulsion combined with autonomous, unwanted emergency brake activation while in motion represents a severe, un-remedied safety defect that put the lives of my entire family at immediate risk.

For the past year I have been dealing with multiple vehicle failures with our 2025 Jeep Wagoneer. I have worked with my dealer a dozen times. Adnt he vehicle has been under service for roughly 13 weeks. Each time the dealership tells me the issue was a software update or they were not able to "recreate the issue". Our 2025 Wagoneer has been stalling out, shifting to park and then requiring a complete restart multiple times per week. This happens at low speed or at idle. On the afternoon of xxx, while driving the vehicle back from a different dealer for service of the same issue the vehicle stalled out completely on [xxx] just outside of [xxx]. Please see attached video. It is more than apparent that this vehicle is faulty and putting me and anyone else in my family that night drive this vehicle at risk. Over the past 7 months I have documented all issues and the dismissiveness of herb chambers Jeep Chrysler in danvers, MA where we purchased/leased the vehicle from. Herb chambers is stating I have to pay nearly $3000 dollars to exit our current lease. But, this is ridiculous as the vehicle is a danger to drive. Something bad will happen if our vehicle continues to be driven. And given the amount of time and energy I have wasted on trying to resolve these ongoing issues, Jeep/stellantis, should actually pay me for the inconvenience.

Liftgate latch assembly failure: the vehicle experienced an internal electrical short circuit and hardware failure within the power liftgate latch assembly. This defective latch caused a severe parasitic 12v battery drain that repeatedly rendered the vehicle completely dead, leaving it unexpectedly stranded. The hardware failure also triggered a software error loop that locked the power liftgate into an inoperable mode (3-beep lockout). Replacing the liftgate latch assembly successfully resolved the liftgate operation and eliminated the parasitic drain. Uconnect 5 software defects: independent of the physical liftgate issue, the uconnect 5 infotainment system (currently running software build u29. 42, referencing TSB 08-230-24) exhibits significant software bugs and display stability issues. The primary central screen frequently flickers, displays line artifacts, freezes, and repeatedly drops wireless apple carplay connectivity. Additionally, when shifting the vehicle into reverse, the rear backup camera feed fails to load, displaying only a blank black screen instead of the camera view. This disables primary vehicle setting controls, navigation interfaces, and rearward safety visibility while operating the vehicle.

Car will shudder and shut off while slowing down. The control panel will change to saying "push start button to run. " this has happened 50+ times, including while in slower traffic on the interstate. It is very dangerous because I am stopped suddenly in traffic and have to restart the car and put it back in gear in order to move. Car has also started and run, but the control panel remains in the "push button to start" mode while driving, so none of the control panel is available. This is dangerous because I have no idea what my speed is.

I was driving on [xxx] and I noticed the battery meter started going down from 13 and ended at 9 and the vehicle shut of and put itself in park while the vehicle was still moving. There were other cars behind me and the car would not restart. I had to get a jump and it restarted. The 48volt battery is faulty information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

Problem occurs randomly and have not been able to consistently repeat results. Vehicle stops and shuts off and puts itself into park. Restart vehicle and it drives normally. It did this once pulling out of a parking lot into traffic, oncoming traffic was able to stop to avoid us. We brought it to the dealership to be looked at and they found nothing wrong. They did say codes were in the computer but since they weren’t active they couldn’t do anything about it. No lights stay on after the car is restarted. It has done this multiple times.

The contact owns a 2023 Jeep Wagoneer. The contact stated that the vehicle intermittently went into park(p) and turned off while merging into traffic with the message "stop/start required" displayed. The vehicle also shut off unexpectedly while idling in park(p). The contact was forced to restart the vehicle to resume normal operation. The vehicle was initially taken to a dealer, and the failure was attributed to the gasoline in the fuel tank; however, the failure returned the following day. The same dealer later diagnosed the vehicle with a defective auxiliary battery inside the alternator. The dealer refused to honor the warranty, prompting the contact to seek repairs from an independent mechanic. The part to repair the vehicle was currently on a national backorder, and there was no estimated date for the parts to become available. The manufacturer was notified of the failure but only directed the contact to a parts website; however, the necessary part could not be located. The vehicle remained unrepaired with the independent mechanic. The failure mileage was approximately 39,000.

I’ve had issues with the blind spot sensors. After driving a mile or two on open road, the warning pops up saying “blind spot sensors unavailable” then the lights on the mirror stay on. This was happening a few months ago so the right sensor was replaced. Now it’s happening again. In a vehicle that is two years old this shouldn’t be an issue.

While in drive the entire car turned off and systems shut off. I was in a busy street and it turned back on and all flashing alert lights were on.

While driving my car engine just shuts off without any warning. My car had a message on the dash after the engine stopped saying to shift the car to park and the emergency parking brake came on. I had to switch my four ways on in the middle of the road. If this happened on a busier street my vehicle would have been hit because I could not drive my car to the side of the road. It was just a dead stop without any notice there was a problem. No dash lights before the engine stopped or anything. Just messages stating to put the car in park after the problem. I have two little girls who are regularly in my vehicle with me and it is scary to think that my Wagoneer engine can just decide to shut off at anytime with no warning.

2023 l series ii Wagoneer 84,444 miles full bench 2nd and 3rd row - my family was travelling in the car and the second row driver side seat unlatched and forcefully slammed my daughter into the back of the driver seat. No aggressive driving and no warning lights on the dash. The car dinged then slammed my daughter's face into the back of the driver seat. Caused swelling and a black eye on the left side. Also caused a spinal injury on the c2 and c3 joint that we are still getting information on the issue. I am submitting this in hopes that this does not happen to someone else's family like it did mine. My family of 4 and 3 kids that are family friends. The event took place on 6-11 and I am writing this report on 6-12. No inspection has been done on the car due to still being at the hospital consulting a specialist on the spinal issue.

I submitted an issue last week for the vehicle putting itself in park while driving and loss of brakes while driving. I brought the car to an authorized dealer and they told me they fixed the issue. It is now happening again. This is a major safety concern!.

Several times, the car put itself into park while driving. Two times, the brakes failed while driving. The brake was pushed all the way to the ground, but the car would not stop.

The contact owns a 2022 Jeep Wagoneer. The contact stated that while driving at an undisclosed speed and attempting to make a turn, the vehicle failed to accelerate and then lost motive power with no warning lights illuminated. The vehicle was towed to the dealer, where it was diagnosed that the fuel pump and fuse had failed and needed to be replaced. The vehicle was not repaired. The contact stated that the failure was related to a known electrical failure with the vehicle. The manufacturer was made aware of the failure. The failure mileage was approximately 32,000.

The automatic emergency braking (aeb) system falsely engages under normal driving conditions when no obstacles, vehicles, or other hazards are present. These false activations occurred at very low speeds, while stopped, while parking, and while the vehicle is in neutral. When this happens, the vehicle brakes abruptly, shifts itself into park, and shuts off entirely. This is not normal system operation and creates a significant safety concern because the vehicle has stopped abruptly and disabled itself unexpectedly on numerous occasions while moving. While my vehicle was in neutral and moving through an automatic car wash on a track, the automatic emergency braking (aeb) system malfunctioned. My vehicle shifted itself into park and shut down. This sudden engagement caused the vehicle behind me to collide with the rear of my vehicle. As a result, the driver of the following vehicle has filed a collision claim against my insurance policy. My vehicle has been taken to the dealership 6 times for this aeb-related issue, along with other ongoing concerns, on the following dates: 09/11/25, 10/07/25, 11/12/25, 01/19/26, 03/09/26, and as of 6/05/26 is back at the dealership. The vehicle will unexpectedly shift out of gear at low speeds, requiring me to stop and place it back into gear before I can continue driving. The vehicle is currently at the dealership as of 06/05/26. Despite several repair attempts, the problems have not been resolved. I am extremely concerned that the aeb system will continue to malfunction causing a more serious collision and injury. The dealership was able to reproduce the problem in September; however, they have not been able to reproduce it again since that time. I have attempted to document each malfunction, including photos of the failure messages. I can provide additional information (receipts, video from accident, photos etc. ).

The gauge cluster and heads up display does not activate vehicle starts and drives but there is no speedometer no tach etc.

While my wife was operating our 2022 Jeep Wagoneer series iii (5. 7l hemi etorque, ~44,700 miles) at highway speed, the vehicle suffered a sudden and complete electrical power failure. Electric power steering cut out completely while the vehicle was in motion, creating an immediate safety hazard and nearly causing an accident. The vehicle was disabled and required towing. The dealership (safford Jeep) diagnosed fault code p0b32: catastrophic internal hardware and voltage failure of the 48-volt etorque hybrid battery pack. The 12-volt battery was also destroyed as a consequence of the 48v pack failure — the 12v charges exclusively via a DC-to-DC converter fed by the 48v loop; when the pack failed, the converter lost power and the 12v battery was starved of charge. Note: this incident is consistent with the active NHTSA odi preliminary evaluation of 2022 Jeep Wagoneer and ram 1500 etorque electrical failures. Fca/stellantis has acknowledged these failures are likely caused by an electrical concern. My p0b32 event represents a catastrophic failure of the exact system under investigation, with the additional safety consequence of complete loss of power steering at highway speed. Stellantis corporate case #96719164 is open. The vehicle has been repaired (48v battery pack replaced) but stellantis has declined to address the warranty access barrier created by their diagnostic system architecture. The dealer's equipment required a new 12-volt battery installation before it could communicate with the covered hybrid system — a $645 mandatory prerequisite to accessing a federal emissions warranty repair.

On 5/14/26 around 8:00am, I just dropped the kids off to school and entered onto the 5 lane freeway, 290, driving into work. Driving 70 miles an hour, the steering light and a warning light came on and then other lights started flashing. The engine shut off, and the steering wheel felt like it locked-up. I managed to exit off the freeway and the car came to a stop. The car would not restart. A tow was called to take to the nearest dealership. In August 2025, this happened and we were told it was a bad aux battery and it was replaced. Now we are told it is the pdc that is causing the issue.

My car has put itself into park and shut completely off three times in the last week while driving. The cruise control shut off while driving on the interstate. There was a message pop up twice saying service electronic throttle system. I don’t feel safe driving my Jeep Wagoneer at all, let alone with my three children. The first time it shut off I was in the middle of a busy intersection with my family in the car. Luckily the other two times I was at a stop sign, but it’s scary and completely unsafe and unacceptable.

On multiple occasions, when starting the vehicle, the screen on the dashboard remains with the power button and instructions to depress the brake and push button to start. The car starts, but no gauges appear on the dashboard. Turning the car off and back on does not resolve the issue. The car is on and running and will let me shift into gear and drive the car, as demonstrated in multiple videos. Driving the car while a message on how to start the car is concerning as I cannot see/view the speedometer or any other gauges. Additionally, the indicator that the driver’s door is open is on when the door is shut. Turning the vehicle off, exiting and locking does not resolve the issue and the screen remains illuminated with the same message. These issues have been reported to the dealer and each time I have been told they cannot reproduce the issue-most recently in may 2026 when the vehicle was inspected, even when showing them photos and videos.

Vehicle: 2024 Jeep Wagoneer (base model) the vehicle has experienced ongoing and progressively worsening engine performance failures, specifically involving unstable rpm behavior and loss of power during idle and re-acceleration from idle. These defects have been present on multiple occasions and occur under normal operating conditions. While stopped at traffic signals or intersections, the vehicle frequently exhibits sudden and erratic rpm fluctuations, followed by a sharp drop in engine speed resulting in complete engine shutdown. These shutdown events have occurred both while the vehicle is in park and while actively positioned in traffic, creating a hazardous condition. In several instances, the engine stalled unexpectedly while the vehicle was stopped at a red light, requiring an immediate restart in an active traffic environment. In addition, when transitioning from an idle state to acceleration, the vehicle has demonstrated abrupt surging and jerking behavior, causing sudden forward movement. This creates a significant risk of unintended acceleration and near-collision events, particularly in congested traffic conditions or when stopped closely behind another vehicle. The vehicle was presented to an authorized Jeep dealership for inspection. The dealership advised that no diagnostic fault codes were present and no defect could be identified. However, during the dealer’s evaluation, the vehicle did stall while being allowed to roll into the service bay in an idle state, directly corroborating the reported condition. Despite this occurrence, no corrective repair was made, and the vehicle was returned without resolution. The frequency and severity of these symptoms have increased over time, resulting in a vehicle that is unreliable and unsafe to operate. The continued occurrence of engine shutdowns and erratic acceleration behavior presents a clear and ongoing safety risk to the driver, passengers, and surrounding motorists.

While cruising on the freeway at approximately 70 miles per hour with no vehicles or objects ahead. The vehicle suddenly made a loud warning sound and flashed a message on the dash. The emergency brakes were automatically applied and nearly stopped in the middle of the freeway. The car behind had to swerve to avoid a collision. The vehicle then resumed driving forward. I was using the adaptive cruise control.

It seems that when the outside temperature is very warm/hot, when turning the car on or when idling at a traffic light or driving at very low speeds, on occasion the car will abruptly and without warning, shift itself into park and the emergency brake activates. I took the vehicle in for repair on 10/23/25 and was told there was a "thermostat internal failure" and that the "thermostat assembly" was replaced. I was just recently traveling in florida ( reside in NY) and the exact same problems occurred with my vehicle which I can only assume was due to the warmer temperatures that my vehicle has not been exposed to since the last repair as I reside in new york. I feel it should be worth mentioning that when turning off the auto start/stop button, the problems occurred less frequently but still happened on occasion. I've also had 3 other times when the "check engine" light came on. I was told that the first 2 were related to software updates with the transmission. On the other occasion, a "valve body" was replaced. I'm unsure if any of these were related. I've also had to replace the auxiliary battery but I don't think that's related so I didn't upload that file. Although I'm taking the vehicle to be repaired today, I took it in on 04/14/26 because the check engine light came on while in florida when the car shifted itself into park and the emergency brake was activated. The check engine light almost never comes on when this happens which I was told makes it difficult to diagnose issues. I didn't know how long this info is stored so I took the vehicle in upon returning to NY and was given a summary report after they hooked up a scanner. I couldn't get an appointment until today.

The vehicle flashed a critical low battery warning while in operation driving. After traveling approximately 2 miles further, the vehicle warning lights started flashing and the vehicle shifted into park and shut off. In the middle of the road the vehicle could not be shifted into neutral and was stuck in a dangerous place. The emergency flashers shut off after 15 minutes while waiting for a tow truck. This vehicle has had two battery replacements in the last two years.

The vehicle experienced a charging system failure while driving. The battery warning light illuminated and battery voltage dropped to approximately 11. 7 volts while the engine was running. The vehicle continued to discharge the battery while being driven, creating a risk of loss of electrical power and possible vehicle shutdown. Diagnostic trouble codes included p0562 (system voltage low), p0bde (drive motor inverter temperature sensor e circuit high), and p0aee (drive motor inverter temperature sensor a circuit range/performance). The charging system was inspected by an independent repair facility. The serpentine belt was verified to be functioning properly and related fuses were checked. The repair facility diagnosed a failure of the 48-volt etorque belt starter generator (motor generator unit/mgu). The replacement part is reportedly on backorder. The condition is repeatable and occurs during normal driving. The battery warning lamp and low voltage condition were observed and documented. This failure creates a potential safety concern because the vehicle can lose charging capability while operating on public roads.

I am reporting a serious and unresolved safety defect involving a 2024 Jeep Wagoneer series ii 4x4 (VIN: [xxx] ) with approximately 34,000 miles. The vehicle has experienced repeated power steering warnings and functionality issues, and on multiple occasions (approximately three incidents) has unexpectedly shifted itself into park while actively driving. These incidents have occurred since fall 2025 and continued in January 2026 and now March 2026, demonstrating the issue is ongoing and recurring. The vehicle was in the dealership for over three weeks between January and February 2026, at which time a repair was confirmed before the most recent occurrence. Despite ongoing repairs, the issue has not been resolved and no permanent repair path has been identified. The vehicle is currently back at the dealership with no confirmed resolution. The most recent incident occurred on 3/18 when the vehicle shifted into park while in motion, requiring a restart in the roadway. Shortly after arriving at my destination, the battery died and the vehicle became inoperable and required towing. The combination of electrical issues, including power steering warnings and a dead battery, along with the vehicle unexpectedly shifting into park, creates a significant and unpredictable loss of drivability and presents a serious safety risk.
