When letting off the accelerator to slow coming to a stop I would press the brake pedal. but the motor would increase RPMs and I had to use both feet to stop the vehicle. Then I had to put the car in neutral and the RPMs would increase even though I was at a stop and then I had to put it in Park before the RPMs would drop. I removed the driver’s floor mat encase it was effecting the accelerator. The vehicle didn’t act this violent but it failed to decelerate several times before I could get it to my local dealer.
