2023 Jeep Wagoneer Electrical Problems

Our vehicle was purchased in December of 2025. Aprox. One month after purchase the vehicle unexpectedly turns off while driving. Fails to start. Along with multiple other issues. Its has been in the shop over the course of that time more than four months and is in the shop current day 14sept2026. We have spend roughly $10,000 to date and continue to be financially and emotionally ravaged. Sealants has been no help. The purchasing dealership also refuses to make it right.

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.

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.

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".

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.

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.

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 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)

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.

The contact owns a 2023 JEEP Wagoneer. The contact stated that while towing, the vehicle experienced a serious and recurring safety failure where the trailer lights would function for approximately five minutes before a portion of them would blackout. This failure renders towing unsafe and illegal, as it compromises visibility and traffic law compliance. The contact referenced NHTSA Campaign Number: 26E006000 (EXTERIOR LIGHTING, ELECTRICAL SYSTEM) however, the VIN was not included in the recall due to the vehicle not being within the 2024-2025 range listed on the recall notice. The vehicle was taken to the dealer on three separate occasions for the same failure. During the first visit, the dealer stated the issue was with the trailers; however, the contact paid for independent inspections that confirmed both trailers were in proper working order. During the second visit, the dealer performed a software update, but the failure persisted. During the third visit, the dealer diagnosed the issue as a known manufacturer software defect with no current resolution available. The vehicle was not repaired, due to no other options of repair besides a recall. The manufacturer has been notified of the failure. The failure mileage was 25,335.

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

On 10/27/25, the thermostat on my wagoneer exploded. It was supposedly repaired on 10/30/25. I read in the wagoneers forum that the thermostat is a common issue, but it could be the result of engine problems. On 2/4/26, I took my vehicle in for a routine oil change. I didn't drive the vehicle for a few days. On 2/7/26, I was driving and received an Error Message stating Max Engine Oil Level Exceeded. Immediate Service required. I returned it to the dealer to fix that issue. On 2/15/26, I noticed that my engine sounded louder than normal and by 2/16/26, the check engine light was on. On 2/18/26, I received an error message saying the engine temperature was too hot. I took it back to the dealership where it is today. I believe the wagoneers have faulty engines that need to be recalled.

This complaint involves a 2023 Jeep Grand Wagoneer L Series III, a full-size luxury SUV. The vehicle has experienced repeated electrical and powertrain failures culminating in complete loss of propulsion. On 01/22/2026, while traveling approximately 45–50 mph, the vehicle abruptly shut down without warning. The engine lost power, dashboard displays went black, and multiple warning lights illuminated simultaneously. I was forced to steer to the shoulder while a trailing vehicle had to swerve off the roadway to avoid a collision. This was a near-miss event and represents a serious safety hazard involving sudden loss of motive power at highway speed. Prior to that event, the vehicle had already stalled at a traffic light and had exhibited repeated check engine warnings, low-voltage faults, and module communication errors. The servicing dealer documented multiple diagnostic trouble codes affecting the Body Control Module (BCM), Ignition System Control Module (ISCM), and Powertrain Control Module (PCM). Manufacturer technical service bulletin software updates were applied in attempts to correct the issue. Despite these interventions, the electrical instability persisted. On 02/12/2026, only days after an auxiliary battery replacement intended to address voltage concerns, the vehicle would not start and required towing to the dealership at my expense. Additional fault codes are currently under review. The vehicle is also subject to an open recall with no remedy available, and the power running board motor has failed with replacement parts unavailable. This pattern of electrical failure, sudden shutdown in motion, and inability to reliably start presents an ongoing and unacceptable safety risk to occupants and surrounding motorists. The vehicle is available for inspection and has been repeatedly evaluated by an authorized dealer.

My air conditioning first went out in 2024 in 105 degree weather with a 3 month old baby, the dealer found the issue and fixed it. Then it went out again recently in the same type of weather and now since I am out of my warranty they are trying to charge me for the same issue, this is definitely a hazard to my health and the health of my children being that the weather can’t afford anyone with no AC. Plus they are refusing to see this as a manufacturer issue, when obviously it is. So I am complaining because this is definitely an electrical issue that could lead to other problems and the manufacturer needs to take responsibility and issue the recall because I am not the only consumer experiencing these issues. The faulty AC could lead to a fire or other serious issues that possibly cause injuries to me or my children

The contact owns a 2023 Jeep Wagoneer. The contact stated that on several occasions, while driving at various speeds and continuing to accelerate, the RPM failed to respond as needed. Additionally, while slowing down the RPM failed to lower. The contact stated that the check engine warning light illuminated, or the message to check the user manual for proper oil and fuel usage was displayed. The vehicle was taken to a dealer, where it was diagnosed, and determined that a system update was needed. The vehicle was repaired, but the failure reoccurred within several months. Additionally, the contact stated that while driving on several occasions at various speeds, the entire instrument cluster became inoperable, with the speedometer remaining at 0 MPH, or the message to "Depress Brake Pedal to Start Vehicle" was displayed. The vehicle was taken to the same dealer on several occasions, where it was diagnosed and determined that both batteries needed to be replaced. The vehicle was repaired, but the failure reoccurred within a month or two. The contact stated that on one occasion, the electrical cluster was replaced. The vehicle was repaired, but the failure reoccurred within a month. The manufacturer was notified of the failure. The failure mileage was unknown.

Incident

Nov 25, 2025

For the past five months, the vehicle has stalled nearly every other day, including while backing out of driveways or parking spaces and when slowing to stop. Each time, the engine suddenly shuts off without warning, the transmission automatically shifts into Park, and the emergency brake engages. An engine warning light appears with a “battery fault” message. The repeated engine shutdowns and automatic braking create a serious safety risk, particularly when backing into traffic or stopping at intersections. In several instances, the vehicle would not restart for several minutes, leaving it disabled in the roadway. The vehicle has been taken twice to the authorized Jeep dealership in Stonecrest, Georgia, but the service department was unable to reproduce or correct the issue. The problem persists, and the “battery fault” light continues to appear intermittently. Component or System: Engine and electrical system (battery and power management) Availability for Inspection: Vehicle available upon request

The vehicle was bought June 2023, starting September 2023 we have had continual electrical problems. The blind spot warning system constantly activates and takes over. The automatic braking system randomly activates for no reason. The car will go into full braking and stop. This will happen at all speeds to include highway speeds. Now I am getting check engine lights and the code changes every time the light activates. When we take it to the dealership for service all we get is "we can't replicate the issue" and nothing is fixed. I ran a Car Fax and found that instead of coding the problem that it was brought in for, Jeep has coded it as maintenance inspection or electrical system checked. This is even when modules, radios or electrical systems have been replaced. I have a feeling that Jeep is coding this way to avoid recalls or to hide problems. I would think this constitutes fraud. My Jeep has serious electrical issues that Jeep will not address. I am stuck driving it as it is my only vehicle.
