WHEN I WAS TRYING TO PARK MY TOYOTA HIGHLANDER 2005 IN FRONT OF THE BUILDING WHERE I WORK, BACKING UP, THE ENGINE IDDLE WENT EXTREMELY HIGH AND I TRIED TO STOP, BUT I COULD NOT DO IT BECAUSE THE STEERING WHEEL AND THE BRAKES LOCKED. I TRIED TO PUT THE GEAR IN NEUTRAL, BUT INSTEAD, IT WENT STRAIGH TO DRIVE, SO IT CAUSES MAJOR DAMAGES TO 2 VEHICLES BEHIND MINE, AND OTHER 3 IN FRONT OF MINE TOO. ALSO MY VEHICLE DESTROYED A MAIL BOX AND A TREE, BUT I COULD NOT STOP UNTIL MY HIGHLANDER STOPPED BY ITSELF TOTALLY DESTROYED. I ENDED UP IN THE HOSPITAL WITH SOME TRAUMA.
