Jeep Wagoneer headlights problems

Filed Sep 23, 2026 · Electrical · SC

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

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.

Hi, I need to bring my 2022 Wagoneer back in for service. I was just in the shop a few days ago for a persistent check engine light, and the issue has returned. The check engine light came back on four days after I picked up the vehicle. This morning the vehicle stalled twice at a complete stop. The front headlights flickered and the engine shut off, but the electronics inside stayed on. I had to press the Start button to restart the engine. I also received a “Start/Stop Unavailable” message. Because this is now a repeat failure, combined with a safety-related stall, I need the vehicle fully rechecked for: ESS/Start-Stop system malfunction Auxiliary battery condition Battery current sensor BMS/charging system PCM software updates Any TSBs related to stalling or ESS on the 2022 Wagoneer Please document this as a repeat repair attempt, and if needed, I would like this escalated to a Stellantis Case Manager since the issue is safety-related and occurred immediately after a previous repair. Please let me know the earliest available appointment. Thank you.

This vehicle is not equipped with an Auto High Beam feature. The result of this is that when the Headlights are in Auto Mode, the Manual control of the High Beams is disabled. Most people leave their headlights in Auto mode to ensure that they dont forget to turn them on or off, but then the high beams are inoperable. This can pose a significant safety concern when you consider that when someone is driving and needs the use of the high beams they have to take their eyes off the road to fumble around with the headlight dial so they can turn it to manual to enable the use of the high beams.

Additionally, the headlights were flashing, and the camera screen was blank. The contact stated that while depressing the brake pedal, additional force was needed to stop the vehicle. There was an abnormal horn sound detected. The contact stated that the engine overheated and the vehicle stalled. The vehicle was jump-started. The contact was locked out on several occasions.

The vehicle was taken to the local dealer, where the battery was replaced, but the failure recurred. The vehicle was taken to another local dealer, Charbonneau Car Center (346 1st Street West Dickinson, ND 58601); who was unable to duplicate the failure. The vehicle was not diagnosed or repaired.

The main head unit for the infotainment system, specifically the software. Upon failing a software update in August 2024, the vehicle started switching itself from English to Italian, from Standard to Metric units, the high beams would no longer function, the auto locking doors after 15mph would no longer work, the emergency pedestrian sensing braking was turned off, the entire infotainment screen randomly shuts off and comes back on as well. Without readily available high beams my ability to see further distances at night was diminished. 2)The uninitiated change in language and units of measure made it more difficult to verify vehicle speed and other important settings with intervention to return the system to English. 3) Largest concern, auto locks not turning on, without notifying the driver, left my young children at risk of opening the back doors and falling out of the vehicle at high speeds. The dealership has tried to fix this twice, they have updated the software to current version and reset the system. They also reset the customer programmable features, which corrected the issue with the high beams, but the other issues with software remain, including the auto locks at speed, language change, units change and screen shutting off and on. I have also contacted Jeep customer service, they do not have a remedy in place and verified the software is up to date. After reviewing Jeep Wagoneer forums, this is effecting many owners of the Wagoneer after that fall 2024 update, and all the dealerships are scratching their heads. But without autolocks at speed, this is a big issue. No warning lights came on to let me know, and the bug seems to be in all software versions for the Wagoneer from Fall 2024 to current.

This Jeep has gone back to the dealership 3 times for dangerous Undrivability, twice on the back of a tow truck, and third time retrieved by the dealer for repair. It has endangered my family on multiple occasions, each for a different reason, making this car unsafe to have my family drive in. It is less than one year old. Only 1 month after purchasing, it died in a parking lot with my family in the car. It had to be put on a flatbed back to the dealer for a computer replacement. The second time, it died in my driveway and again had to be brought on a flatbed to the dealer. The third incident was the most dangerous and the incident that must be flagged. With my kids in the car, my wife came to a stop sign. The car shook and jittered, the entertainment system went out, and the headlights flashed. A driver at the intersection thought my wife had "flashed the lights" and proceeded into the intersection, nearly causing an accident. I had the dealership come and get it, they applied a fix for the engine start-stop recall and said that likely fixed it. This car is unreliable and unsafe, and Jeep refuses to buyback the car, telling me only to start arbitration. They have refused to even give me a manager, and not returned all my calls.

When the master lighting switch is set to the auto position, the high beam headlights will not activate unless the master lighting switch is first changed to the ‘on’ position. This is the same as the recall for the 2021 Jeep Grand Cherokee L which was issued in approximately October 2021. I figured this out when I was searching the internet for why my high beam lights were not working. It should be noted that I just recently purchased this vehicle and am the second owner.
