WAS DRIVING 2006 TOYOTA SCION XA TO WORK IN MORNING GOING AROUND CURB I HAVE DRIVEN FOR 8 YEARS. AFTER BRAKING TO TAKE CURB NO LONGER HAD CONTROL OF VEHICLE. DROVE LONG WAY ON CURVY ROAD AND COULD NOT GAIN CONTROL OF CAR. ENDED UP GOING OFF ROAD AT APPROX 40MPH HIT A TREE STUMP AND THEN FLIPPED VEHICLE. NO AIRBAGS DEPLOYED OR SEAT BELTS LOCKED UP. CALLED TOYOTA AND WAS TOLD THAT AIRBAGS ONLY GO OFF IF VEHICLE REACHES A CERTAIN RATE OF DECELERATION AT POINT OF IMPACT. THIS HAPPENED 2 WEEKS PRIOR TO NEWS OF ACCELERATION PROBLEMS. I HAD NO CLUE WHY I LOST CONTROL OF CAR AT CURB. EVERYONE AROUND ME SAID IT WAS PROBABLY BLACK ICE FROM FOG BUT MY SON WHO WAS RIGHT BEHIND ME DID NOT HIT ICE OR LOSE CONTROL. AFTER RESEARCHING THE WEB, I FIND HUNDREDS OF TOYOTA OWNERS WHOSE AIRBAGS DID NOT GO OFF AND THEY WERE ALL FED THE SAME LINE I WAS. DID OUR SENSORS NOT DETECT DECELERATION BECAUSE OF BAD ACCELERATION SENSORS? DID I LOSE CONTROL BECAUSE MY CAR DID NOT DECELERATE WHEN I PUT FOOT ON BRAKE AT CURB. I HAVE BEEN DRIVING FOR 35 YEARS AND HAVE NEVER LOST CONTROL OF MY CAR. I WAS LUCKY AND MY INJURIES WERE NOT LIFE THREATENING OR CRIPPLING; BUT I WOULD LIKE TO KNOW WHAT HAPPENED AND WHY I WAS NOT PROTECTED BY MY AIRBAGS WHEN MY CAR HIT A TREE DEAD ON. I DO HAVE PHOTOS FROM THIS ACCIDENT AND THIS VEHICLE IS STILL AVAILABLE AT INSURANCE TOW LOT FOR VIEWING AND TESTING. PLEASE CALL FOR DETAILS. *TR
