I parked my car on a flat surface/parking lot and as I turned the key in the ignition to the off position the car choked, sputtered and either bucked or started to roll backwards onto the highway. It has never happened before but I'm worried there is a systemic problem or design flaw or electric mayhem happening with my new vehicle and I'm worried. In six months the above problem happened, I replaced four headlights, the interior trunk latch pushed through the driver's side interior door panel and is unusable and a few weeks ago my EPS light came on and I lost all power steering without warning in a school zone.
