I was in an accident in 2019 a few months after purchasing car since then my engine light was on. Had it serviced and the engine light was still on. Was told it could be a transmission problem. Every now and then it would shuttle once started. Today it didn't want to excellerate while driving.
I stopped twice on an intersection and a traffic light and the engine revved up to 3000 to 4000 rpm involuntarily from between 500 and 1000 rpm and I had to step hard on the brake in order not to have the vibrating car move forward. No, I did not hit the brake and the gas pedal at the same time. After I shifted the car into neutral at the next red light it did not show this behavior again. So it looks like a software glitch in the shifting computer part.
When I moved gearshift from park to drive, car accelerated violently. I do not believe I accidentally used the accelerator, this occured in parking lot. After moving about 20 feet I hit a heavy gate with enough force to do extensive damage to car including bent chassis.
