SLOWLY ENTERED RITE AID PARKING LOT AT 5-10 MPH. TURNED RIGHT INTO A PARKING SPOT. LIGHTLY TAPPED THE BRAKE AND THE ACCELERATOR WENT FASTER THAN IF YOU WERE DRIVING ON THE HIGHWAY. CAR JUMPED THE CONCRETE BUMPER ONTO THE WALKWAY. HAD TO CUT THE WHEEL ALL THE WAY TO THE RIGHT TO AVOID HITTING THE BRICK WALL OF THE STORE AND DROVE INTO THE PARKING LOT GUARD RAIL. CAR WENT INTO A HIGH SPEED SKID AND WHEN IT CAME OUT OF THE SKID WAS STILL ACCELERATING AT A VERY HIGH SPEED AND HAD TO TURN THE IGNITION OFF FOR IT TO STOP. THERE WERE SKID MARKS AND SMOKE. AIR BAG DID NOT GO OFF. WAITING TO HEAR FROM TOYOTA WITH A DATE TO HAVE THE CAR INSPECTED. WOULD LIKE FOR TOYOTA TO BUY BACK MY CAR WHICH WE HAVE SPENT TOP DOLLAR HAVING TOYOTA MAINTAIN IT FOR THE LAST FIVE YEARS, WHICH INCLUDED THE 100,000 MILE SERVICE JUST A WEEK OR TWO BEFORE THE ACCIDENT. DO NOT FEEL SAFE DRIVING THIS CAR AGAIN. PLEASE ADVISE. *TR
