“I was driving north on I64, and a car in front of me suddenly stopped. Cruise control was on, but when i applied the brake, my car did not stopped, and cruise control speed up, before decreasing speed. Instead of turning off, and allowing the car to slow down. I had to swerve, causing to go off on the side of the highway, and held my foot on the brake for almost a mile, along the side of the highway, before the car came to a stop”

“I was driving on a road when the car suddenly accelerated for no apparent reason. I hit the brake and nothing happened. When the car accelerated, it was like when you hit resume when you have cruise control on. I did not have cruise control on. To avoid hitting a vehicle in front of me, I went off the road to the right, hit a chain link fence and stopped in a field. The car was declared a total loss by the insurance company. Earlier that day, the car was giving me a warning to brake, when I was not near another vehicle. …”

“Was pulling into a parking spot on the 2nd level of parking garage and the Jeep accelerated and hit the cement wall at front of garage space. It accelerated on its own. The front of the jeep was crushed, and I ended up with a fractured sternum and a seat belt hernia which I will have surgery in the next couple of weeks. The airbags did not deploy. And I did not press on the gas pulling into the parking spot --- it just accelerated on its own. When I first got in the car the system showed that systems disabled, but the then the message went away. …”

“Bought vehicle in October - dealer was only able to give me the vehicle 2 months later. When I picked up the vehicle it smelled like something electric was burning. I texted my sales guy from the lot he didn't respond immediately I thought maybe it's just something outside the vehicle. Brought it home found it there is a recall on this vehicle and it doesn't accelerate efficiently. When I took it back to the dealership the dealer couldn't fix it and refused to take the vehicle back. I have paid my car payments for a vehicle I can't use. Please help me resolve this issue”

“The accelerator throttle be became stuck in open throttle and an error message came on. I pushed the brakes it eventually stopped after like 5 seconds and slowed down when the error message came on and eventually came to a crawl, it was stuck ⅘ of the way, but if I pushed it further it would not go. It was in track mode and I was using the paddle shifters. So I pulled over, stopped, and put it in park and restarted and it was fine. There were no symptoms prior to the issue. This was the first time it happened. It has not been inspected. It is available for inspection upon request. …”
