I backed up my car at the parking lot, the steeling wheel was lockd up after the car moved 6-7 feet could not turn around, when i changed the gear back to drive(D)and try to move ny car back to previous position, my car was slided back( consider was the hill side at the parking lot) i've tried 3 times and it was same problem when the engine was still on, i changeg the gear to Park(P)then changed the gear to Drive(D) and applied the gas pedal 3 times but look like the engine idle(nothing work on)and the car did not move ahead(no trasmision apply) i turned off and restart the engine then apply the gear to (D) e verything turn back to normal and everything was working fine,do you guy have any idea, i really concern about the safety for my family if it happens on the street or freeway?
