I left my daughters house with my jeep wrangler and as I shifted into forward gear there was no power on my wrangler 4XE hybrid. I move the vehicle to the side of the road and towed it to the dealers. After a little over two weeks they got it repaired. After that I have read reports of this kind of thing happening in traffic. When I lost power the engine light and stability control light came on. It is now repaired but I’m having second thoughts about the safety of the vehicle since I sometimes transport my grandchildren in the vehicle.

The two main wire harnesses are faulty. It would not charge or hold a charge. Driving it was dangerous and would stop drastically at any given random moment. A jerking motion would occur while driving. Lights on dash would come on, engine, charging fault station. Charging fault. And lightening bolt warning signs. Sometimes it would say don’t drive call for assistance. The dealership has had my vehicle since June 4 2021. The parts I’m told won’t be available until end of January 2022. I purchased the jeep on April 30th 2021. It’s very scary when you’re on the road, w my family and it decides to lock up or sounds like the transmission is falling from the under carriage. Luckily we weren’t rear ended or pushed through an intersection.

Unknown. Car came to a sudden stop while driving and the lights beside the gear started flashing. A message on the dashboard popped up that said for me to put the car in park and then select my desired gear. Major safety concern for a car to just shut down for no reason while driving down the street. Luckily I was on a back road with little traffic. Afraid to drive the car on major highways or at higher rates of speed where this malfunction could cause a serious accident.

On 9/16/21, my vehicle dangerously lost power, following a very loud sound and a violent shudder. Power for braking and steering was lost. The vehicle had no response to the accelerator pedal. I attempted to coast to the shoulder of the road, when the vehicle slammed into park on its own while still traveling at roughly 15mph. The wheels locked and the vehicle came to a violent stop by itself, likely not activating the brake lights. The cooling fans came on at full speed, climate control cancelled itself, and the vehicle locked in park. While using the built in emergency button, the vehicle telematics shut down and dropped the dispatcher. I completed the emergency service call using my phone. The vehicle was towed to the dealer, initial reports are that it is not drivable, the main hybrid battery pack fuses are blown. The prior night, the vehicle failed to charge using the Jeep EVSE cable.

Charging Fault Error came on as my wife was driving home when her 2021 Jeep Wrangler 4XE suddenly shut off and came to a immediate halt. She was barely able to prevent a major accident, which could've caused serious injury to herself and others on the road. Vehicle would not restart and was not even able to put the vehicle in neutral to push out of harm's way. The moment it happened I received a message on my Jeep UConnect app that a Charging Fault Error occurred. I didn't know what this meant, but about 60 seconds later my wife called me in distress and told me what happened. She was terrified couldn't even drive the rest of the way home and had to stand in 100F heat for an hour waiting for a tow truck. Result: The Jeep Wrangler 4XE is still in the shop (it's been in the dealership for over 3 weeks now, and we've owned it for 3 months and 3500 miles. They have no diagnosis and say they are still ordering parts. Asked 2x to speak with upper management at FCA and was told someone would call in 24 hours, it' been over 72 hours now.

As I approached a stop sign while braking, the Jeep seized up, shut off, and gave the Electronic Stability Control warning. I attempted to restart and it didn’t start or get out of park. It then gave Blind Spot Monitoring System error and Service Charging System error. I’m grateful that I was at a stop sign unlike some of the other reports of this issue that were on the highway. It was quite a jolt when the vehicle seized. The vehicle has been at the dealership since 8/24. It was thought the hybrid battery needed replacement. A new one gave the same errors to the service team. The vehicle remains with the service department awaiting another battery.

I was driving vehicle on HWY 610 in Houston, Texas at approximately 55-60 MPH. Suddenly, vehicle simply stopped working in the middle of driving. Everything on my dash was reading zero. Car were swearing to avoid hitting me. I also had a baby in the backseat of my vehicle. Suddenly, the dash started to read place car in park, Service Charging System. The P at my gear shift was flashing rapidly. I was able to slowly and dangerously coast to the emergency lane. Where I was able to turn the vehicle off. This is a very dangerous situation. At this point, Jeep has no idea what the problem is an this is very frustrating.
