ON FEBRUARY, 18, 2011 AT APPPROXIMATELY 1:30 P.M. I GOT INTO MY 2004 TOYOTA HIGHLANDER, WHICH WAS PARKED IN A PRIVATE PARKING LOT AT 1 MEETINGHOUSE RD. IN CHELMSFORD, MA. I TURNED THE KEY ON, STARTED THE CAR, AND PUT THE GEAR IN REVERSE TO BACK OUT OF THE PARKING SPACE. AS I TOUCHED THE ACCELERATOR PEDAL WITH MY RIGHT FOOT, THE CAR ACCELERATED UNCONTROLLABLY AT A SPEED THAT DID NOT CORRESPOND WITH THE PRESSURE I HAD PUT ON THE PEDAL. I IMMEDIATELY PUT MY FOOT ON THE BRAKES, BUT THERE WAS NO RESPONSE FROM THE BRAKE SYSTEM. THE STEERING WHEEL WAS TURNED TO BACK OUT IN A COUNTERCLOCKWISE DIRECTION, AND WITHIN NO MORE THAN 4 SECONDS, THE CAR CRASHED INTO A BUILDING APPROXIMATELY 20 FEET FROM WHERE THE CAR WAS INITIALLY PARKED. THE CAR WAS TOTALLY UNRESPONSIVE TO MY EFFORTS TO BRAKE SUBSEQUENT TO THIS SUDDEN AND INEXPLICABLE ACCELERATION. I'M LUCKY I WASN'T KILLED, BECAUSE MY VEHICLE WAS TOTALED. *TR
