The vehicle experienced a charging system failure while driving. The battery warning light illuminated and battery voltage dropped to approximately 11. 7 volts while the engine was running. The vehicle continued to discharge the battery while being driven, creating a risk of loss of electrical power and possible vehicle shutdown. Diagnostic trouble codes included p0562 (system voltage low), p0bde (drive motor inverter temperature sensor e circuit high), and p0aee (drive motor inverter temperature sensor a circuit range/performance). The charging system was inspected by an independent repair facility. The serpentine belt was verified to be functioning properly and related fuses were checked. The repair facility diagnosed a failure of the 48-volt etorque belt starter generator (motor generator unit/mgu). The replacement part is reportedly on backorder. The condition is repeatable and occurs during normal driving. The battery warning lamp and low voltage condition were observed and documented. This failure creates a potential safety concern because the vehicle can lose charging capability while operating on public roads.
We were driving and approaching a stop light at a major intersection when the vehicle stalled out. We heard it sputter at first and then cut off. We tried multiple times to restart, but to no avail—just kept sputtering. This is the second time this has happened. The first time was also reported to NHTSA, and I was driving alone and ascending a colorado mountain when it stalled out. Thankfully, both times, we were able to remain safe; however, this is a huge problem as both times we were on major roads.
While driving at lows speeds approaching a stop light the vehicle will just shut off and shift into park. I have to hit the brakes, make sure its in park, and hit the start button, it restarts then doesn't do it until randomly later it does it again. There is a check engine light on.
I was driving and the vehicle shut down and shifted into idle mode while in driving mode. Smelled something burning. Turned car off and back on quickly (as was on the road) and the smell was gone but the check engine light was on. I took to dealership next morning and it has been three weeks now that it has been at the shop. They are saying it’s an issue with the hybrid part of the battery/engine that has gone bad.
While driving on [xxx] towards vail, CO—the Jeep Wagoneer suddenly stopped accelerating while going up the side of the mountain. Lights on the dashboard were lit up, including the braking light. I was in the right hand lane, so luckily there was a shoulder on the side of the road, albeit very shallow, that I got into and immediately called roadside assistance from the vehicle. Prior to this moment, I had been driving for a little over an hour with no issue or warning. The safety concern is high, especially since I was on [xxx] accelerating up a mountain with lots of traffic behind me. If I was in the left lane or if a semi truck was right behind me, I could have been hit/hurt/killed. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).
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.
Driving normally and instantly, many alert lights came on. Brake booster failed and difficult to stop vehicle. Vehicle engine power decreased. Radio screen shuts down frequently which is less an issue of safety but reflects instability of entire electrical system which seems to cause errors in critical systems such as braking and other safety equipment. Concerns regarding critical malfunctions seem to be mounting in the Wagoneer and will likely result in injury at some point if not already.
