The failure pattern owners describe
The 2022 Wagoneer's powertrain generates serious safety complaints involving sudden, complete loss of electrical power while driving. Owners report the engine shutting off without warning at speeds ranging from 3 mph to 65+ mph, accompanied by loss of power steering and brake failure. The electronic parking brake engages automatically, the transmission shifts itself into Park, and all dashboard displays go black. These incidents have occurred on interstates and city streets, forcing owners to coast to a stop without steering or braking capability—several owners describe nearly hitting oncoming traffic. Dealerships consistently report no diagnostic codes and cannot replicate or diagnose the failure. One owner's vehicle drove itself up a driveway with the door open and mother-in-law inside, landing in a ditch.
The eTorque mild-hybrid 48-volt battery and Motor Generator Unit (MGU) fail frequently. One part list shows 282+ reported MGU failures with 45+ day backorders; repair costs reach $4,000 and dealerships deny warranty coverage. Multiple owners have needed battery replacement twice in under two years.
Transmission faults cause involuntary shifting to Park at low speeds and during stops. One vehicle was stuck in 4WD low at 700 miles with transfer case and rear differential damage already present. Owners also report violent shaking at highway speeds (starting around 48 mph) affecting the entire vehicle, which persists despite new tire installation and professional rebalancing. ABS lockup during braking has occurred after unsuccessful service visits. Dealership responses consistently cite inability to diagnose, unavailable software updates, or unavailable parts.

I was driving through the parking lot at my daughter’s school, and the vehicle shut off entirely when going at slow speeds. The vehicle lost all power steering, and braking was more difficult. Stopped safely, and the vehicle wouldn’t restart. Dealership confirmed it was a failure of the 48v battery system.
We were bringing our 2022 wagoneer to the dealership to have them investigate an issue with the battery light coming on this morning. While driving on interstate 95 north, all power cut out on the car, the power steering stopped working and the brakes failed.
