VEHICLE REFERENCED LEFT TARGET, STOUGHTON,MA, PARKING LOT AT 12:10PM-11-11-14 (WITH 7YR OLD GRANDSON CAR SEATED BEHIND DRIVER & DRIVER WAS IN SEATBELT). WHEN EXISTING LOT, ANOTHER CAR BACKED OUT OF PARKING SPACE AND HIT RT, BACK END OF REF CAR. DRIVER OF REF VEHICLE LOOKED BEHIND AT VEHICLE THAT STRUCK HER AND, AS SHE TURNED FORWARD & BARELY STEPPED ON GAS TO MOVE AWAY FROM VEHICLE THAT HIT HER, THERE WAS A LOUD CLICKING NOISE, TIRES STARTED SPINNING AND CAR TOOK OFF ACCELERATING W/O CONTROL OF BRAKES, SHIFT OR STEERING. REF VEHICLE HIT CURB, ACCELERATED UP HILL FROM PARKING LOT AND WENT AIRBORNE, CRASHED DOWN INTO GUARDRAIL AT APPROX 45-50MPH AND AIRBAGS DID NOT DEPLOY. DRIVER IS SURE REF VEHICLE WOULD HAVE CONTINUED TRAVELING FORWARD IF NOT FOR GUARDRAIL! DRIVER OF VEHICLE (AND GRANDSON) WERE TAKEN IN AMBULANCE TO HOSPITAL AND IN TRIAGE ALL DAY. DRIVER SUFFERED HEAD AND EYE INJURIES AND HEMATOMAS FROM NECK DOWN. GRANDSON REPORTED SLIGHT BACK PAIN AND WAS RELEASED. THANKFULLY, NEITHER OF REF VEHICLE'S OCCUPANTS WERE MAIMED OR DIED. AFTER MUCH RESEARCH, FOUND THERE ARE 2006 TOYOTA CAMRYS WITH ETC ISSUES. AGAIN, NO CONTROL OF ANY ASPECT OF CAR - COULD NOT PUT IN NEUTRAL, GEAR SHIFT JUST "FLOATED" OVER ALL GEARS WHEN TRYING TO USE! WOULD LIKE FOR NHTSA TO INSPECT GAS PEDAL FOR "WHISKERS" OR OTHER PROBLEMS THAT LED TO THIS. AS DRIVER OF THIS VEHICLE, I CAN HONESTLY STATE THAT I HAVE A GREAT DRIVING RECORD AND I AM NOT PRONE TO "DRIVER ERROR" PUTTING FOOT ON GAS PEDAL
