2022 Jeep Wagoneer: battery drain or dead battery

Filed Aug 8, 2026 · Body, Electrical · FL

Liftgate Latch Assembly Failure: The vehicle experienced an internal electrical short circuit and hardware failure within the power liftgate latch assembly. This defective latch caused a severe parasitic 12V battery drain that repeatedly rendered the vehicle completely dead, leaving it unexpectedly stranded. The hardware failure also triggered a software error loop that locked the power liftgate into an inoperable mode (3-beep lockout). Replacing the liftgate latch assembly successfully resolved the liftgate operation and eliminated the parasitic drain. Uconnect 5 Software Defects: Independent of the physical liftgate issue, the Uconnect 5 infotainment system (currently running software build U29.42, referencing TSB 08-230-24) exhibits significant software bugs and display stability issues. The primary central screen frequently flickers, displays line artifacts, freezes, and repeatedly drops wireless Apple CarPlay connectivity. Additionally, when shifting the vehicle into reverse, the rear backup camera feed fails to load, displaying only a blank black screen instead of the camera view. This disables primary vehicle setting controls, navigation interfaces, and rearward safety visibility while operating the vehicle.

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. My husband had to navigate across 4 lanes of traffice with now power or brakes or steering to get to the shoulder. The car was towed to our dealership, and they indicated our alternator died and battery died. There were no check engine lights indicating we had an alternator issue or that we should not drive the car in for service. We talked to the service department about the batter light the morning of 12/2/2024 and they had us drive it in. This needs to be looked at as it was a very dangerous situation to navigate on the interstate.

on March 23, 2024, the 2022 Jeep Wagoneer Series 3 turned off while at a stop light. We were at a red light and completely stopped and the engine turned off on us. We had the vehicle in for a routine oil change, and afterwards the vehicle battery died 3 times before the dealership replaced the battery. We are unsure if the dead battery is related to the engine turning off on the March 23 incident. I am unsure if there were any warning. We are also getting a error message that says "Uconnect Box requires service. Please visit an authorized dealer." The dealership tries to tell us that the software is up to date. We have issues with our CarPlay always connecting to the vehicle when it should every single time.

The 2022 Wagoneer (first model of vehicle) we own has had SEVERAL issues dating back to purchase in 04/2022. The original battery died in 08/2022 when the car had ~3000 miles. The electrical system was to blame in draining the battery dealer said. dashboard lit up and shut on and off. The dealership ‘repaired’ with new battery. Other various issues with seats and electrical malfunctions have taken place both before/after that. But last night, about 20-30 minutes into a drive, the check engine and battery lights came on. A couple mins later, the AC and volume didn’t work and then the dash lit up with over 10 buttons. At this point, I was attempting to pull over, but I was on a busy road with no where to go. A couple minutes later, the dash starting flashing on and off. At this point, the steering wheel locked up, the brakes no longer worked and the whole car dash and video screen was dark. I was going 65mph at the time with by 12 year old son and 10 year old daughter. I could not move the wheel and had no brakes as we were entering bend in road and semi truck coming at us. I had to make a decision to either run car off road into a field or house or try to jerk wheel. It took all my strength to turn wheel and avoid the semi truck. We escaped a major wreck or death by a matter of inches. Worrisome and scary to say the least. Fortunately after that turn, the road straightened out and I drove until car ran out of speed. Once it stopped (thankfully there were no people or stopped cars or traffic lights when we didn’t have brakes or steering), the car went into park. Flashers didn’t work. This is a reoccurring problem on my car and we have friends who also had a 2022 Wagoneer and the exact same thing happened to them and they avoided disaster too. There is obviously a problem and I cannot drive that car ever again and cannot put my kids back in that car. Also, it took 4 hours for a tow truck to arrive as Jeep didn’t seem to help much. We narrowly escaped death.

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.
