MY SON WAS DRIVING ON THE INTERSTATE WHEN THE STEERING WHEEL LOCKED. HE WAS NOT ABLE TO TURN THE STEERING WHEEL TO NEGOTIATE THE CURVE OF THE ROAD, SO HE CRASHED INTO A CONCRETE CONSTRUCTION BARRIER. THE POLICE REPORT STATED THE CAUSE OF THE ACCIDENT AS "DEFECTIVE STEERING." THE VEHICLE WAS TOWED TO THE DEALERSHIP, AND A REPORT WAS FILED WITH GMC CORPORATE. THEIR INSPECTION OF THE VEHICLE FOUND NO DEFECT WITH THE STEERING. WHAT THIS MEANS FOR ME IS THAT MY INSURANCE AND I MUST PAY FOR ALL OF THE REPAIRS (IF THE INSURANCE COMPANY DOESN'T TOTAL THE VEHICLE). IT ALSO MEANS THAT, SINCE THEY COULD NOT FIND ANYTHING WRONG WITH THE VEHICLE, THE INCIDENT OF THE STEERING LOCKING UP COULD REOCCUR, CAUSING SERIOUS INJURIES OR FATALITIES. IN DOING RESEARCH, IT APPEARS FROM THE NUMBER OF COMPLAINTS AND THE CLASS ACTION SUIT FILED AGAINST GMC THAT THE 2010 ACADIA HAS DEFECTIVE STEERING. MILEAGE OF VEHICLE IS APPROXIMATE.
