IGNITION LOCK FAILED ALLOWING KEY TO BE REMOVED IN ANY POSITION AND NOT SECURING THE AUTO IN A PARKED CONDITION. HENCE THE VEHICLE ROLLED BACK INTO ANOTHER CAR. THE VEHICLE IN QUESTION HAS ONLY 87243 MILES ON IT AND THIS PART SHOULD NOT FAIL, ESPECIALLY AS IT DID TO ALLOW THE CAR TO MOVE WHEN IT WAS SUPPOSEDLY TURNED OFF, AND IN PARK. THIS VEHICLE HAS HAD PREVIOUS TRANSMISSION ISSUES AS WELL AND WAS THE SUBJECT OF A RECALL. *JB
