2022 Jeep Wagoneer electrical system problems

“An over the air update was sent to the vehicle. After it failed, an error code was provided and multiple electrical features were dismantled, including back up assist and collision warnings as known issues.”

“On XXX 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 (XXX) 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 XXX 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 XXX (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…”

“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…”

“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.”

“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…”

“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.
