WHILE ATTEMPTING TO BACK OUT OF A PARKING SPOT, THE CAR SUDDENLY ACCELERATED AND SLAMMED INTO THE VEHICLE WAITING FOR THE SPACE. I PUT THE CAR IN DRIVE TO GET OFF HIS BUMPER, THE CAR SHOT FORWARD WHILE STANDING ON THE BRAKE. THE CAR WOULD NOT STOP. FINALLY JUMPED A CURB AND RAN INTO PARKING METER TO STOP CAR. DEALER SAID NOTHING IS WRONG WITH THE CAR.*JB
