NHTSA Complaint #10672331 — 2014 GMC SIERRA

MY VEHICLE STARTED WITH A VIBRATION ON OR AROUND 12,000 MILES. THE VIBRATION SLOWLY INCREASED AS TIME WENT ON. I MADE APPOINTMENT WITH THE DEALERSHIP WHERE THE VEHICLE WAS PURCHASED.(CAPITALAND MOTORS) AT THIS TIME THE VIBRATION WAS STRONG ENOUGH TO VIBRATE THE BACK WINDOW. IT WOULD START AT 30MPH AND GET WORSE AT 45MPH. THE MECHANIC CHECKED BALANCE AND ROAD FORCE THE TIRES. BUT TOLD ME THAT THE VIBRATION WAS NORMAL AND HE COULD FIX MY BACK WINDOW. I CALLED GMC AND FILED A COMPLAINT. THEY TOLD ME TO TAKE IT TO ANOTHER DEALERSHIP. I DID ON 11/25/14. THIS TIME I TOOK IT TO GOLDSTEIN BUICK-GMC. THEY COULD FEEL THE VIBRATION IN THE STEERING WHEEL AND SEAT. THEY CHECK TIRES AGAIN. THEY FELT IT WAS THE TIRES AND WANTED ME TO BUY NEW ONES. TOLD ME THE TIRES WERE NOT UNDER WARRANTY. THAT DAY I CALLED GOODYEAR AND FOUND OUT MY TIRES WERE UNDER WARRANTY, THEY WOULD BE PRORATED. GOODYEAR CHECK MY TIRES AND THEY ARE FINE. AT THIS TIME NO ONE CAN FIND THE PROBLEM AND I FEEL IT HAS BECOME A SAFETY ISSUE. THE VIBRATION IS REALLY STRONG AND GETTING WORSE AND THEY HAVE NO ANSWER. *TR
