When the car is traveling approximated 2-10 mph, the automatic transmission accelerates and brakes as the automobile bucks a few times. Their is a loud thunking noise and then goes back to normal. From time to time the car gets stuck in 2nd gear, which forces me to pull over and restart the engine. Windows are supposedly automatic up and down, but don't work properly 50% of the time. Rear back speaker plays intermittently. When parking and shutting down engine, the emergency brakes turn on and off. The engine key is getting stuck in the ignition. Overall issues seem to be electrical or computer related. I have taken back to dealer twice in the last 6 moths and the problems keep building.
