Electrical System Problems of Jeep Wagoneer - part 1

About a week ago, I received a warning that my lane management assist required servicing. As of Tuesday (10/06), as I slowed to a. Stop sign, my car started beeping, put itself in park and turned off. It flashed a message that stated a restart was required. Then today, I was getting the same lane management warning and as I was stopped, my car did the same thing, threw me into park, put a bunch of different warning messages then said power steering requires service. I proceeded to drive home since I was about ten minutes away, shut my vehicle off for a few minutes and tried to restart it, the car would not restart. The vehicle had to then be towed to dealer for repair. Since purchasing the vehicle in 01/2024 I have had ongoing electrical issues and had to turn the vehicle in for service. But they have never found an underlying issue, they have just replaced batteries and cleared codes.

I am writing to formally submit a dangerous and sudden electrical system failure on my 2024 Jeep Wagoneer. I purchased this vehicle brand new from lee Jeep in wilson, nc and it currently has only 38,000 miles—just 2,000 miles past the standard factory bumper-to-bumper warranty. This issue represents a severe safety hazard and appears to be a direct, consequential chain reaction resulting from a dealer-performed service and software flash completed just 1,000 miles ago. Chronology of events: 37,000 miles: the vehicle's thermostat failed. Lee Jeep replaced the thermostat and performed a required computer system software update. 38,000 miles: immediately following these updates, the vehicle began completely shutting down and stalling at stoplights and stop signs. Simultaneously, the electric power steering (eps) completely cut out, leaving me stranded in active traffic with heavy, unassisted steering. Current status: the dealership diagnosed a blown main engine fuse and is demanding $450 to replace it. They have refused to cover this under a goodwill adjustment, claiming their local branch "cannot do it. " a full vehicle shutdown and loss of power steering at intersections puts my life and the lives of my passengers at immediate risk. Unresolved root cause: a high-amperage engine fuse does not blow without an underlying cause. I am deeply concerned that charging $450 to swap a fuse without diagnosing the systemic current spike—likely tied to the recent software update or the auxiliary stop-start battery logic—will leave me stranded again. Proximity to warranty: given that the vehicle is a 2024 model and barely past the 36,000-mile mark, a catastrophic electrical failure of this nature should be covered by the manufacturer.

On October 3, 2026 my 2022 Jeep Wagoneer completely shut down while driving down the road without any warnings! this is actually the 3rd time this vehicle has shut down on me and it is absolutely terrifying and a huge risk for anyone riding in this vehicle when it happens, as well as other vehicles in its pathway. The first time it happened (11/27/24) I was driving on a state route about 20 miles from home when I had messages come up on my dashthat functions were going to start shutting down, one after another just minutes prior to it shutting down. I fortunately got pulled off into a parking lot befor I lost the power steering and my vehicle shutting down. The car was taken to a dealership and they had it from 12/5/24 - 12/23/24. The mgu was not charging and so it was replaced. Then about 2 weeks later, while making a local trip just a few miles from home, and without any warning it shut down again! no chance to pull over! it's so terrifying to be in a lane of traffic and no power to get you off the roadway!! car went to dealership. They had my car from 1/2/25- 2/21/25 (about 2 months!) and without a loaner car I may add!! again vehicles electrical systems were not charging and the bcm was throwing ecu mismatch codes and the were instructed to replace the entire power pack unit. And now we are on event #3 of losing the entire operation of the power system all while driving down the road and this is absolutely terrifying!! the mild hybrid system in this vehicle is not reliable and is putting peoples lives in danger when it shuts down like this ans without warning to let you know to get off the roadway! I have 6 grandchildrenthat I transport around in my vehicle and fortunately have not been with me on any of these occasions but it is one of my biggest fears is that it could happen when the are in the car and it ends in tragedy. One son who is in law enforcement and has seen many tragedies , has even expressed concern, because he has 2 under 3 yrs old that I transport.

Third time while driving the car just stops stays on drive but car is completely dead. Have to put in park and turn off and on car to go. Also have a few times of the car is in a parking spot and then go to reverse stop limit brakes and it won’t let you go when you put it into drive. It does the same thing and it’s stuck until you turn the car off and back on. . The most scary thing is twice it’s been in the middle of the intersection that it’s died today. It happened for the fourth time three times in a row. I have taken my car into Jeep and has been there for over 69 days in total for many different electrical issues. They keep blaming it on the battery these in corrosion. I don’t see how they can get away with this.

Instrument panel dash frozen. Instrument dash panel frozen at the screen where it says start/stop press brake to turn the vehicle on, we can’t see how fast we’re going when driving. This has occurred on multiple occasions. We’ve taken it to a Jeep dealership. Who reset the pcm but it does not resolve the issue.

I recently had an oil change at the dealership I purchased the Wagoneer from. Three days after the oil change was completed, I was sitting at a stop light when the vehicle completely shut down, and the power steering went out. I started the vehicle back up and a power steering service notice popped up. That same day, the large central display screen kept flashing on and off, when it finally shut completely off. Six days later, I was driving home from work when I noticed the engine kept running up into the 6-7000 rpm's if I tried to drive over 40mph. I drove under 40mph the rest of the way home (about 10 minutes) and started noticing how loud the engine sounded and the temperature gauge was increasing. I was about 1 minute from home when my daughter and I could feel the heat coming from the engine inside the cab of the vehicle. It was so hot, I was concerned the vehicle was going to catch on fire. I parked it away from my home and called the dealership. They sent a tow truck and inspected it the next day. They stated the engine thermostat went out, and the auxiliary battery failed. There were never any warning lamps or messages displayed while this was happening. If I would not have been paying attention to the gauges and would have been further away from home, this vehicle could have overheated completely and potentially caught on fire putting my kids, myself, and others on the highway in danger. There was a campaign reference: 26b issued by stellantis in April 2025 stating this exact issue and noting the repair to be performed, however, they only included specific Wagoneer's equipped with a 3. 0l gmet6 engine. My engine is a 3. 0l i6 hurricane and was not included in the campaign, even though it is the exact same issue and this could have all been avoided.

While driving my vehicle suddenly shuts off the engine and puts the vehicle into park. This has happened multiple times now and once on I-66 while merging onto I-495. This seems very dangerous.

Highway shaking, car stalling when in idle, vehicle wouldn't shutoff, steering wheel locked, vehicle wouldn't start, electrical issues: screen shutdown, error messages,.

To whom it may concern, I am writing to report a serious safety concern involving my Jeep Wagoneer. The vehicle has experienced intermittent stalling issues, creating a hazardous driving situation and leaving me stranded. The vehicle unexpectedly stalled, causing a loss of power and leaving me without reliable transportation. Given the potential safety risks associated with a vehicle stalling while in operation, I am extremely concerned about the possibility of this occurring again, particularly in traffic or at highway speeds. Adding to my frustration, after contacting the dealership for assistance, I was informed that it would be approximately eight days before the vehicle could even be inspected. A delay of this length for a vehicle experiencing a potentially dangerous drivability and safety issue is unacceptable and leaves me without confidence in the safety and reliability of the vehicle. I am requesting that this matter be investigated promptly and that appropriate action be taken to address the stalling condition. I also believe this issue warrants review for any potential broader safety concerns affecting other Jeep Wagoneer owners. Please document this complaint and advise me regarding any available assistance, escalation options, or known remedies related to this condition. Thank you for your attention to this matter. I look forward to your prompt response.

Front parksense sensors not working even after being cleaned. Drivers side seatbelt saying not buckled even when buckled. Needing to rebuckle for it to register. Low-voltage warnings appearing while driving. Multiple dashboard warning lights appearing simultaneously - low-voltage and check engine light. Loss of electrical power while driving (so scary!) the vehicle shifting itself into park when coming to a stop in traffic. Apple carplay disconnecting sporadically.

While driving, vehicle suddenly displayed low voltage and "power saving mode" error messages. Multiple systems shut down including ac and radio. With engine stop/start disabled, engine died while slowing to a stop, automatically engaged parking brake, and vehicle shut down. Was able to restart and limp home. Vehicle would not re-start after shutdown. Battery was completely discharged (<9v) and still hot to the touch 4 hours after turned off. Battery tested good, but was replaced out of caution. Current static battery voltage 12. 3v. Charging voltage while running 13. 4v. Voltage while running with heavy electrical load (ac, radio, heated seats, headlights on) 12. 9v. Believe this to be related to known issues with etorque generator.

Within less than 24 hours of picking the vehicle up from the thermostat repair on xxx6, it began shutting off on its own and losing engine rpm, including while being driven on the freeway and while stopped at a red light. It shut off completely on its own two times in the first 24 hours back in my possession, with no warning that the vehicle was about to lose power. Losing power on the freeway risks a sudden loss of motive power at highway speed and a high-speed collision, and shutting off at a red light risks being unable to move out of an intersection or accelerate away from a hazard, with a heightened risk of being struck. During these failures the vehicle displayed a battery warning code and, separately, a "service transmission" warning; both appeared and then cleared. These symptoms first appeared on xxx, within hours of the vehicle being returned from the prior repair. The failures have not yet been reproduced by a service center; the vehicle is scheduled to return to the place of purchase, grogans town Dodge Jeep ram on xxx for diagnosis, and the same vehicle was in this dealership's service department of another dealership 2 hours from our home because thats where we were when the thermomstat issue occured on xxx for the separate cooling-system failure. The vehicle is available for inspection on request. Mileage: approximately 78,000. VIN: [xxx]. (for context only: I have since learned that 2024 Jeep Wagoneers have been reported to have a battery/electrical drain issue that can cause the vehicle to shut off. ) information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

The engine cooling system failed while my husband and I were driving on the freeway at night: the thermostat stuck closed and cut off coolant flow to the engine, causing it to overheat and become unsafe to continue driving. This occurred at approximately 10:00 pm on xxx roughly two hours from home over a holiday weekend, with two occupants in the vehicle. The vehicle had to be towed, but it took nearly four hours to get a tow truck, leaving us stranded on the freeway at night; because we were stranded so far from home, my [xxx] father had to drive two hours to reach us at 10:00 pm and then drive us two hours home, arriving around 1:00 am, which put an elderly driver on the road late at night and created further risk. There was first a low oil pressure code and the engine was revving without the gas being pressed. Then that code went away and the engine overheating code came on along with an occasional battery code. The vehicle was diagnosed and repaired by bud's Chrysler Dodge Jeep ram between xxx and xxx the dealership confirmed the stuck thermostat and coolant cut-off and replaced the thermostat. The vehicle is available for inspection on request. No manufacturer, police, or insurance inspection has taken place to date. Mileage at time of failure: approximately 78,000. VIN: [xxx]. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

The car was stuck in the intersection causing a threat to life and well-being of those not only in the Wagoneer but to the other drivers as the car could not be moved until towed. This took over an 1. 5 hours to get towed and traffic had to be diverted by police.

When driving my vehicle suddenly shuts off the engine and puts the vehicle into park. This has happened multiple times now and everything shuts down, power steering, etc goes out and I’m afraid it will cause a serious accident. This seems very dangerous. Dealership tells me they don’t have any idea how to fix it.

My 2022 Jeep Wagoneer has experienced four separate incidents of complete power loss while being operated. During these events, the electrical displays went dark and electrical functions stopped working on the entire vehicle on [xxx], the vehicle lost all power while I was pulling into my garage. It would not release from park normally and required wheel skates and towing. The dealership replaced the battery, but the symptoms later returned. On [xxx], the vehicle lost all power while traveling approximately 20–30 mph near [xxx] and [xxx] in heavy holiday traffic. I could not reach the shoulder and stopped in a turning lane without a collision. The vehicle required towing. The dealership told me it performed a computer reset and software update. In approximately February 2026, associated with a February 11 service entry, the vehicle again lost power while driving. I was able to restart it and drive to the dealership. My recollection is that I was told another reset/software update was performed, although the online service summary says “check battery. ” on [xxx], the vehicle lost all power while traveling approximately 35–40 mph on [xxx]. I was able to pull into a service station, restart the vehicle, and deliver it to chris crain Chrysler Dodge Jeep ram in benton, arkansas, that day. As of September 30, 2026, the vehicle had remained at the dealership for 33 days without a completed repair communicated to me. A dealership representative, kim, told me by telephone that technicians had reproduced the failure, suspected an electrical component or connector short, and contacted Jeep engineers. I do not have a confirmed written diagnosis. I am concerned that another unexpected complete power loss in traffic could cause a collision. Similar symptoms have recurred after prior repair efforts, but they all share the same underlying cause. I request review of these incidents as a potential safety defect. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

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.
