This is a 4cyl car with eassist. Unintended acceleration - the car while going downhill or sometimes uphill, accelerates on its own after releasing the gas pedal. I almost hit another car once because of this. Jerking - the car while decelerating from 50-40 mph to 30-20 mph jerks after releasing the gas pedal (with an intention of decelerating) or while applying brakes. This has been happening regularly since I bought the car in oct 2012.
