WHILE DRIVING THE CAR ON THE FALMOUTH CONNECTOR WITH THE TOLL BOOTH IN SIGHT, I LIFTED MY FOOT FROM THE ACCELERATOR TO DECELERATE AND SUDDENLY THE ACCELERATOR JUST TOOK OFF. I IMMEDIATELY APPLIED THE BRAKE BUT THE CAR CONTINUED TO TRY TO ACCELERATE, I THEN APPLIED BOTH FEET TO THE BRAKE AS I TRIED DESPERATELY TO STOP THE CAR WHILE THE FRONT WHEELS WERE SPINNING AND BURNING RUBBER. I TRIED TO SHUT DOWN THE IGNITION WITH THE PUSHBUTTON ON THE GEAR SHIFTER AND ALSO DESPERATELY TRIED TO MOVE THE GEAR SHIFTER FROM DRIVE BUT COULD NOT. NEITHER THE IGNITION BUTTON NOR THE GEAR SHIFTER WOULD RESPOND. THE CAR CONTINUED TO TRY TO ACCELERATE BUT I WAS ABLE TO STEER THE CAR INTO THE SNOW BANKING OFF THE ROAD AND IT FINALLY STALLED IN A BLACK CLOUD OF RUBBER AND SMOKE. THE DEALER DID AN INSPECTION OF THE CAR AND COULD FIND NOTHING WRONG AND DENIED KNOWING OF ANY PROBLEMS. I HAVE BEEN TRAUMATIZED BY THIS EVENT AND CONTINUE WITH MEDICAL ATTENTION IN RECOVERY. *NM
