ON THE DAY OF DECEMBER 10, 2009 I WAS ARRIVING HOME FROM WORK AS I ALWAYS DO. I WAS PREPARING TO PARK MY 2005 TOYOTA TACOMA TRUCK IN FRONT OF THE GARAGE AS I ALWAYS DO. AS I BEGAN TO BACK UP THE ENGINE ROARED CAUSING THE TRUCK TO PLUNGE BACKWARD INTO THE GARAGE DOOR AND HOUSE. I WAS UNABLE TO STOP THE VEHICLE EVEN WHILE HAVING MY FOOT ON THE BRAKE. HOWEVER THIS WAS NOT THE FIRST TIME THIS HAD HAPPENED. THE FIRST TIME WAS AT A TRAFFIC LIGHT. AS I STOPPED AT THE LIGHT, WITH A CAR IN FRONT OF ME, WITH MY FOOT ON THE BRAKE THE ENGINE ROARED AND THE TIRES SCREECHED CAUSING THE TRUCK TO ACCELERATE . FORTUNATELY I WAS ABLE TO PUT THE TRUCK IN NEUTRAL ALLOWING ME TO AVOID SLAMMING INTO THE CAR. THE SECOND TIME I WAS TAKING MY WIFE TO HER ONCOLOGIST APPOINTMENT FOR A CHEMOTHERAPY TREATMENT. AS I APPROACHED THE TURNPIKE BOOTH TO GET MY TICKET THE ENGINE AGAIN ROARED AND PLUNGED FORWARD AND I WAS UNABLE TO GET MY TICKET. THANK GOD THERE WAS NO CAR IN FRONT OF US. I WAS FINALLY ABLE TO BRING THE TRUCK TO A STOP BY PLACING IT IN NEUTRAL. AGAIN VISIBLY SHAKEN, I TURNED THE TRUCK AROUND EXPLAINED TO THE TICKET TAKER WHAT HAD HAPPENED AND I RETURNED HOME. I IMMEDIATELY CALLED THE DEALER WHERE I HAD PURCHASED THE VEHICLE AND ASKED IF THEY HAD HEARD OF ANY SIMILAR INCIDENT. THEY INFORMED ME THEY HAD NOT HEARD OF THIS BEFORE. AT THIS POINT IN TIME NO ONE IS WILLING TO HELP RESOLVE THIS PROBLEM. I AM UNABLE AND UNWILLING TO USE THIS TRUCK BECAUSE I AM AFRAID SOMETHING FATAL MY HAP
