I was traveling on the [XXX] on Sunday [XXX] and while started smelling brakes and I got off at the service area and pressed on the brake pedal and the vehicle wouldn’t stop. I had no brake pedal and just heard a clicking sound. There were people everywhere and I didn’t want anyone to get hurt so I had no choice but to drive the vehicle towards a yellow pole which did stop the vehicle but I have been told after the car was towed to a shop that there is an error code B22A9 and believe it was caused by some ecu failure of some sort. The vehicle is in really bad shape and airbags also didn’t deploy. I would like this to be investigated as I would not feel safe in this vehicle if it’s repaired and returned to service. It is a 2021 Jeep Wrangler 4xe and I am aware of issues being reported with the battery but nothing for this problem except for other mentions on the internet on owners having similar problems intermittently. The jeep will be towed to Pohanka Jeep in Salisbury Md. There wasn’t any warning lights. I give permission for the vehicle to be inspected at anytime. I feel this vehicle is a danger to the public safety being it was just serviced and inspected by a Jeep dealership 2 weeks prior and the brakes suddenly fall and now there’s a code with something to do with an ecu or electronics having to do with the brakes failing. Could have been killed in the accident or seriously hurt if I hadn’t exited off the road and used the pole to stop the vehicle.

While driving my vehicle in four-wheel-drive low, with no lockers engaged I noticed that the rear wheels at different times were dragging, I could also hear and feel the ABS module actuating. During these events I would have diminished breaking capabilities and no ABS warning lights. it was doing it under 5 miles an hour at first and then higher speeds. I got a service ABS, service traction control, service stability control, four-wheel-drive unavailable, service four-wheel-drive system Messages all of a sudden, and i disengaged the four-wheel-drive lover back to 2 Wheel Drive. At this point the brake pedal was hard and would not move, my back left wheel was completely locked. I shut the vehicle down waited a few minutes and restarted it, all of the lights were still active but I was able to move the vehicle. I began traveling forward and the rear wheels alternated locking up. I started backing up to move to a safe position, the brake pedal became hard and I was unable to stop causing my vehicle to collide with a wall, speed was below 5 miles an hour but still caused damage to my left rear quarter panel and fiberglass top. After we assessed the damage, I put the vehicle in 2 Wheel Dr., disconnected the battery for 30 minutes, and was able to drive the vehicle to a parking lot in 2 Wheel Dr. After this point and not having phone service, use a satellite communicator to call a local off-road recovery nonprofit that I volunteer for, they were able to assist in bringing a trailer out to tow my vehicle home as it is unsafe to drive and my children were with me. Unloading the vehicle off the trailer all the lights were gone with the exception of a check engine light is now on. The vehicle is currently sitting in my driveway and will be requesting a tow to the local dealership for them to troubleshoot .

Today this morning I parked, put the gear in park and all of a sudden the car ravaged up and jumped forward, causing me to go through a fence and stopped. I had my foot on the break the whole time.

I pulled my Jeep into my driveway. I put the car in park with my foot on the brake. When I went to turn the car off, I heard a loud sound coming from the car. the car jerked forward, my foot still on the brake, and then it took off into the side of my house and garage. I tried to stop the car with the brakes and it wouldn't stop. After it hit the house, I looked down and the car was still in park. I had to restart the car as it shut off after hitting the house, I put the car in reverse and backed it up. When I put it back in drive the car wouldn't move. Only reverse worked. After an hour the car started working in drive. I had the car towed to the dealership. They told me that there were no error codes and that the care is fine. I now have zero confidence in this car. This is my fourth Jeep Wrangler and I never experienced anything like this. Has anyone experienced or heard of a similar issue?

How to use these: a complaint is one owner’s report, filed voluntarily and published unverified. Patterns matter more than any single story. If several owners describe the same failure at similar mileage, put that system at the top of your pre-purchase inspection list. Back to the full 2021 Jeep Wrangler 4-door verdict →
