HAVE A 2006 BMW 750I AND WAS OUT RUNNING ERRANDS. I STOPPED AT THE DRY CLEANERS TO GET MY CLOTHING. I ONLY TURNED THE VEHICLE OFF FOR ABOUT 10 MINUTES WHILE I WENT INSIDE THE DRY CLEANERS. I PAID FOR MY ITEMS AND WENT TO RESTART THE ENGINE BUT WHEN I PUT THE VEHICLE IN REVERSE NO MOVEMENT HAPPENED. I SHUT THE VEHICLE DOWN COMPLETELY AND RESTARTED IT. I PUT THE VEHICLE IN R FOR REVERSE AND IT SWITCHED BACK TO P FOR PARK. THE VEHICLE AGAIN WAS TURNED OFF AND RESTARTED AND IT DID THE SAME THING NOTHING. I CALLED MY SPOUSE AND HE WAS ABLE TO PUT THE VEHICLE IN REVERSE BY EDGING THE VEHICLE WHILE IN REVERSE MODE. WHILE MY SPOUSE WAS BACKING OUT OF THE PARKING SPACE THE VEHICLE JERKED. I OFTEN NOTICE THAT IF I PARK ON A HILL AND GO IN REVERSE THE VEHICLE...
