Is this a known problem?
The manufacturer has sent NHTSA 23 service bulletins or notices for the 2022 Jeep Wagoneer that deal with this problem. Newest first.

Most of these are service bulletins, the repair instructions manufacturers send to dealers. NHTSA generally leaves safety recall bulletins out of this file, and recalls are listed separately.

What owners wrote
“While driving down the road, I came to a stop and the vehicle started flashing every light then would not restart or allow the vehicle to be put into neutral. Initially thought maybe a battery issue despite my new battery being only eight months old replaced the battery and all the electronics started going haywire requiring the vehicle to be towed.”

“I was driving through the parking lot at my daughterâs 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 wouldnât restart. Dealership confirmed it was a failure of the 48v battery system.”

“Vehicle had one warning light about tire pressure. Tire pressure tested fine. Began to drive. 30 minutes later every light on the dash lit up and vehicle stopped in an intersection and almost caused multiple accidents. Vehicle was finally towed by police and after a month in the shop they said it was a dead battery. But it died while the vehicle was driving and alternator should have been charging it.”

Should you keep driving it?
This page can't tell you that. 1 of 49 reports involved a crash. Owners who file are the ones who had a bad experience, and nobody checks their reports. If the problem affects steering, braking, power or a fire risk, treat it as a safety fault and have it inspected before a long or high-speed drive.
