AS DRIVER APPROACHED A 2 LANE CONSTRUCTION ZONE, THE VEHICLE STARTED TO DRIFT TO THE RIGHT. DRIVER ATTEMPTED TO CONTAIN VEHICLE IN TRAFFIC LANE BUT THE STEERING WHEEL WAS NOT RESPONSIVE. AT SOME POINT THE POWER STEERING ASSISTANCE MODULE REACTIVATED BUT ONLY MANAGED TO DRIVE THE VEHICLE INTO THE CONCRETE BARRIERS ON BOTH SIDES OF THE HIGHWAY RESULTING IN HEAVY FRONT-END PASSENGER SIDE DAMAGE AND CONTACT DAMAGE TO ALL CORNERS OF THE VEHICLE. DESPITE TRAVELING BOTH BACK AND FORTH ACROSS TWO LANES SEVERAL TIMES AND MAKING CONTACT WITH THE BARRIERS EACH TIME, NEITHER FRONT AIR BAG DEPLOYED. DRIVER'S HEAD CAME IN CONTACT WITH HIS SIDE WINDOW CAUSING TEMPORARY LOSS OF CONSCIOUSNESS. PASSENGER'S AIR BAG COVER WAS KNOCKED ASKEW BUT AS NOTED DID NOT ACTIVATE. EMT'S ADMINISTERED MEDICAL ASSISTANCE AT THE SCENE, BUT DID NOT TRANSPORT. VEHICLE WAS TOWED FROM SCENE AND SUBSEQUENTLY JUDGED "TOTALED". I PURCHASED THIS VEHICLE EXACTLY ONE WEEK AND 5 HOURS BEFORE THIS EVENT. NOTICE I DO NOT CALL IT AN ACCIDENT: THIS VEHICLE AND OTHERS FROM THIS MODEL AND YEAR SHOULD BE REMOVED FROM OUR ROADS IMMEDIATELY. MANUFACTURER HAS A "SERVICE BULLETIN" OUT ON THE 'POWER STEERING ASSIST'. THEY REFER TO IT AS A SPECIAL COVERAGE ADJUSTMENT. SEE SB-10183 *TR
