I WAS DRIVING IN A PARKING LOT AND CAME TO A STOP BUT THE CAR THEN ACCELERATED AND I HAD BRAKE HARD TO HOLD THE CAR BACK. I PUT THE CAR INTO PARK. WHEN I ATTEMPTED TO PUT THE CAR INTO GEAR AGAIN, I COULD NOT MOVE THE SHIFTER. I TURNED THE CAR OFF AND RESTARTED IT, AND THE CAR RAN FINE THE REST OF THE EVENING. THE NEXT DAY, I WAS AGAIN IN A PARKING LOT AND AS I TRY TO PARK, THE ENGINE ACCELERATES WILDLY. I WAS ABLE TO HOLD THE CAR WITH THE BRAKES AND PUT IT INTO PARK. ONCE IN PARK, THE ENGINE CONTINUED TO REV. THE SHIFTER WAS NOW STUCK. I TAPPED THE SHIFTER AND THAT ALLOWED ME TO SHIFT THE CAR AND THE ENGINE WENT TO NORMAL OPERATION. AS OF 12/11, THE PROBLEM HAS NOT HAPPENED AGAIN. I WILL BE TAKING THE CAR TO MY DEALER FOR DIAGNOSIS. *TR
