The car has revved high rpm's since purchase, with multiple attempts to get it resolved. Since then, the steering wheel has jerked out of my hand's multiple times, unexpecting, causing the car to jerk while being stopped. The car has also not budged in the middle of traffic while being in drive and the pedal down to the floor until at least a 10 second delay and when doing so the screen that includes the radio, etc panel has completely blacked out and started twitching
