Electrical System Problems of Jeep Wagoneer - part 2

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.

Vehicle will suddenly shut off in traffic. Will not start back up for 1-2 minutes. Control panel near gear selector will flash on and off message reading hold brake and start button. Screen all black. This has happened 3 times this month. Car shut off in car wash, once started it would not shift from park into neutral or drive for 60 seconds. When accelerating on expressway, vehicle will shake then message flashes on dashboard "put in proper gas and oil". Happens weekly. Dealership of course cannot find any issues or replicate codes. . . . Very convenient. Bought new-2023 Jeep Wagoneer series 2 hurricane twin-turbo engine.

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.

My Jeep will randomly not let me back up as it thinks there is something behind it and automatically apply the emergency brake. I brought it to dealership when it was still under warranty for this issue and they could not figure it out. My Jeep will randomly stop as it’s driving, it will still rev when I push the pedal but it will not move in reverse or drive. The automatic shut off says it needs to be serviced and does not work. The automatic emergency braking comes on randomly if I stop. I constantly get alerts that my blind spots are blocked. I’ve cleaned sensors as the dealership has recommended which doesn’t make a difference. My lift gate will only work intermittently. Sometimes it shuts on my kids. My screen only works sometimes. Which is dangerous when I don’t have access to back up camera. I currently owe $31,000 still on this vehicle and I have 5 kids. I really need this vehicle fixed as I cannot afford to get rid of it. It has been unreliable since I’ve owned it and I’m really disappointed in this Wagoneer. It’s very expensive to insure and it’s had nothing but issues. The tow bills are becoming expensive as well.

I purchased car less than 24 hours ago. Service engine light is on. Dealership ran code and say it wasn't diagnosing a problem. And engine light went off. Drove for 3 hours and then engine light came back on. When I drove the car today, I came to a stop at a stoplight and when I went to go the car would not go. Looked down and my car had been gone into emergency parking. This issue was not disclosed to me when I purchased the car.

This is the 3rd time the Jeep wagooner has "bricked up. " the vehicle will shut off without notice and lose all power, the emergency brake comes on and stops vehicle abruptly. This poses safety risk to driver passengers and surrounding vehicles. The car will not be able to be restarted for 30 secs. Once car is restarted, dash lights flash everywhere and car loses power steering. This happen 1st time 2 weeks after I bought a brand new 2024 Jeep Wagoneer. I took it to dealer and they told me it was defective battery. They replaced battery, it has now done it two more times. I took it to dealer again and they once again claim it was defective battery again. 2 defective batteries in 18 mos of new car? there is something else going on w/electrical system in this car that drains batteries and abruptly shuts off vehicle.

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.

When driving the car this winter, noticed the smell of something burning. After that, the heated steering wheel stopped warming. Took it to a repair shop since there was open no recall related to this. Repair shop diagnosis: - heated steering wheel not working due to electrical short. More info below, pictures included. Finding confirmed customer concern. Attempted to activate the heated steering wheel and found the light to come on for roughly 4-5 seconds then shut itself off. Scanned the vehicle and found 2 fault pertaining to the heating element and steering wheel having an open circuit. Removed the airbag and visually inspected all connectors for the steering wheel. Found the 2 pin connector from the steering wheel to the clock spring to be stuck in the clock spring. Further removed the steering wheel and trim pieces around the steering column and visually inspected the clock spring. Found the 2 pin connector between the steering wheel and the clock spring to be melted together and noticed the wires were getting hot to touch when activating the heated steering wheel. Back probed the connector between the clock spring and the heated steering wheel connector and found less than 2 volts present. Monitored and found while the steering wheel was being moved left to right the voltage would fluctuate dramatically. Recommend replacing the air bag clock spring and steering wheel due to melt damage and further monitor voltage and functionality of the heated steering wheel and other accessories. Highly recommend not operating the heated steering wheel until repairs have been made. Could cause more damage to the surrounding components.

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.

I was driving northbound on us 31 near peru, in. I stopped at a red light and my car auto shut off initiated. However when the light turned green, I beganto drive again and the car died/stalled on the highway. The emergency parking break engaged. Oncoming traffic, who saw a green light were not slowing down and I was afraid I would be rear ended while my car was stalled at a previously red, but now green light. It took multiple attempts in quick succession but I was able to restart the vehicle and continue. I was afraid myself and my kids would be hit and killed. Subsequently my car had had battery issues. Randomly the battery had drained or car will not unlock using key fob.

I own a 2022 Jeep Wagoneer with the 5. 7l hemi etorque system. The vehicle has lost all power while being driven on two separate occasions. The first occurred on October 22, 2025, on a major interstate. The second occurred on January 30, 2026, on a state highway. In both cases the engine shut off without warning while the vehicle was in motion, with my wife and four children aboard. Power steering and braking assist were lost. The vehicle locked into park, and I could not get power to shift into neutral or restart it. The January 30 incident required towing. The vehicle was inspected by a mechanic, who was unable to replicate the problem. Since the second failure, I have observed that system voltage drops rapidly during normal driving on nearly every trip. To avoid another shutdown in traffic, I now monitor voltage and pull over to shut the engine off and restart it once it reaches 12. 4v. This takes several efforts each trip to pull over and restart the system. It has produced anxiety in my family about the safety of this vehicle. This is a full-size SUV losing power in highway traffic without warning. It endangers my family and every driver around us. I am aware of odi preliminary evaluation pe24018 covering this vehicle and system, and I am submitting this so my incidents are part of that record.

During normal driving in temperatures below approximately 20–27°f, the vehicle began losing electrical charge as indicated by the malfunction indicator light (mil) and battery warning message. While my wife was attempting to return home, multiple vehicle systems progressively shut down, including electric power steering, abs, auto-leveling suspension, and lane departure assistance. As she was pulling into our driveway, the vehicle completely shut off, resulting in total loss of propulsion and power steering. The vehicle had to be towed to the dealership. This was the second occurrence of this failure. A third incident occurred the following day under similar temperature conditions. During that event, mil and battery warnings appeared again during normal driving. She was able to reach our driveway before complete shutdown occurred. On the most recent incident, the following diagnostic trouble codes were present: p0eec, p1618, p0008, and u0111. These are the same codes that were recorded during the previous two incidents. After the first two failures, kernersville Dodge stated the issue had been repaired and charged us for the repairs. The same failure condition has now reoccurred. This failure results in sudden loss of propulsion and loss of power steering while driving, creating a significant safety hazard.

My 2022 Wagoneer has stalled out 3 times at intersections as a result of the automatic start/stop. This is extremely dangerous! I have been stranded in the intersection 2 out of the 3 times until I was able to turn off/on the vehicle and trouble shoot it.

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.

The lithium battery failed causing a complete loss of power, power steering, power brakes while driving with 3 small children on board. Battery indicator warning on dash. The dealer expressly stated that the car was safe to drive. Obviously that was incorrect. Thank goodness we were able to safely stop and be towed to the dealer. I escalated to "Jeep cares" case number Jeep wagg case 95595257and going on 4 weeks and no one can tell me when the battery will be available and that this battery will only last 3 years. If Jeep has no inventory then that is a red flag and the consequences of this failure puts lives at risk.

The contact owns a 2022 Jeep Wagoneer. The contact stated that while her husband was driving at approximately 10 mph, the vehicle stalled, and smoke was coming from under the hood. The contact stated that the smoke had also entered the passenger cabin. The contact stated that her husband had not mentioned whether any warnings had illuminated. The contact stated that when she arrived to pick him up, the fire was extinguished. The fire damage was confined to the engine compartment. The vehicle was towed to a dealer, but it was not a manufacturer dealer. The vehicle was diagnosed, and it was determined that the generator and the start/stop battery had caught fire and needed to be replaced. The contact was advised that the battery was on national back order. The vehicle was not repaired. The contact stated that she had searched online and associated the failure with an active NHTSA national action number: pe24018 (electrical system, hybrid propulsion system, engine, engine and engine cooling). The manufacturer was not informed of the failure. The failure mileage was approximately 90,000.

While approaching a stop sign at a speed of less than 10mph with my wife and three small children in the car, the engine shut off and the steering/braking became degraded. I was able to restart the car after stopping, but the auto start / etorque does not appear to be working any more. I will be dropping the car off for diagnostics, but after some research this appears to be a common issue which is already under investigation.

Vehicle shut-off while driving. Electrical failure due to voltage issue with hybrid (etorque) system. Los off power while driving vehicle on roadway with potential loss of control. Vehicle taken to dealership and diagnosed with failure of hybrid battery. During my ownership of the vehicle I've had to replace the primary battery 3 times due to ongoing electrical problems with this engine.

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.

On two separate occasions within 2 months of each other, the low battery/voltage warning appeared and shortly thereafter, every warning light in the dash came on and various messages appeared on screen stating that there were power/electrical issues. The car then shut down and died while in motion. Extremely dangerous as in the first instance, the vehicle was in the white mountains region of new hampshire (on a main road, rt. 16), with no cell reception, cold weather, and at night, leaving us stranded. The second occasion happened on a busy highway with my wife and young daughter in the car. We were able to get off the highway when the warning lights came on; however, the car died in downtown boston, at night, in the winter (December). The first time this happened, the car was towed, a "software update" was done, and we were back on the road. Then less than 2 months later, the same thing happened, and is this time diagnosed as the etorque motor. There is an open NHTSA investigation for this exact issue. Investigation:pe24018.

While making a left turn on a green left turn arrow the vehicle for no reason slammed on the brakes without any notice. Causing the car to come to a violent stop. And almost causing us to be rear ended. The violent stop caused both of us injuries to our backs and necks.
