NHTSA Complaint #10543045 — 2010 GMC ACADIA

WHEN ATTEMPTING TO MAKE A LEFT TURN AT AN INTERSECTION, THE STEERING WHEEL BECAME VERY DIFFICULT TO TURN AND I HAD TO USE BOTH HANDS TO TURN THE WHEEL. DURING THE MONTH, THERE WERE SEVERAL MORE INSTANCES WITH SLOW TURNS TO THE RIGHT AND LEFT. THERE IS ALSO A BUMPING NOISE (THUMP, THUMP) COMING FROM SOMEWHERE UNDERNEATH THE STEERING WHEEL. IT IS NOT ALL THE TIME BUT INCREASING AS TIME GOES ON. THE STEERING WHEEL IS MORE BECOMING MORE DIFFICULT TO TURN AND THE INCIDENTS ARE INCREASING. I WENT TO A CHEVORLET/GMC DEALERSHIP THIS MORNING AND WAS TOLD IT WAS EITHER MY POWER STEERING PUMP OR THE RACK AND PINION THAT WOULD NEED TO BE REPLACED. THEY WOULD HAVE TO HAVE MY VEHICLE FOR 2 DAYS, ONE TO TEST IT TO DETERMINE THE EXACT NATURE OF THE PROBLEM AND ONE DAY TO FIX IT. THE COST WOULD BE ANYWHERE FROM $300-$600, DEPENDING ON THE CAUSE. I HAVE READ SEVERAL FORUMS ON THE INTERNET OF ACADIA OWNERS WITH THE SAME ISSUE BUT POWER STEERING PROBLEMS GOING DOWN INTERSTATES WHEN ATTEMPTING TO EXIT ONTO AN OFF RAMP AT A HIGH RATE OF SPEED. *TR
