NHTSA Complaint #10640663 — 2014 GMC SIERRA

I HAVE HAD MY TRUCK BACK THE DEALERSHIP 8 TIMES FOR THE SAME PROBLEM A VIBRATION THAT YOU CAN FEEL IN THE SEAT STEERING WHEEL AND GAS PEDAL, THEY HAVE HAD THE FACTORY ENGINEERS OUT THREE TIME AND LOOKED AND WORKED ON IT, FIRST TIME THE ENGINEER DID A COUPLE OF THINGS AND SAID THAT IT WAS UP TO FACTORY SPECS AND THAT WAS ALL HE COULD DO, I DROVE IT HOME AND BEFORE I WAS A BLOCK AWAY I COULD TELL THAT THEY DID NOT FIX IT, WHEN I GOT HOME I CALLED THE DEALER BACK AND TOLD HIM SO HE CALLED GM AND THE NEXT WEEK THEY SENT OUT THE SAME GUY AND THIS TIME HE WORKED ON 5 OR 6 OTHER THINGS THAT HE DID NOT WORK ON THE FIRST TIME AFTER TELLING ME THEY DID ALL THEY COULD DO THE FIRST TIME. RIGHT THERE TELLS YOU THEY ARE LYING IF THERE WAS NOTHING THEY COULD DO WHY COME BACK AND WORK ON IT AGAIN! BUT AFTER HE GOT DONE IT WAS JUST LIKE IT WAS, I WILL TRY TO LIST SOME OF THE STUFF THAT THEY SAID THEY DID, 1) ROTATED THE TIRES 2) RE-TORQUE THE WHEELS 3) BALANCED THE TIRES 4) BALANCED THE DRIVE SHAFT 5) SHIMMIED THE REAR END 6) CHECKED THE REAR SHOCKS 7) TOOK OFF DEALER INSTALLED MUD FLAPS! 8) CHECKED THE EXHAUST SYSTEM, I KNOW BUT THEY DID 9) ROAD FORCED TESTED THE TIRES TWICE AND REPLACED TWO THE SECOND TIME AND RE-BALANCED THE TIRES. AND I'M SURE I HAVE NOT LISTED ALL THEY HAVE TRIED, AND STILL I HAVE THE SAME PROBLEM, THIRD TIME THE ENGINEER CAME OUT HE HAD THE REGIONAL MANAGER WITH HIM AND THIS TIME THEY DROVE MY TRUCK AND 2 OTHERS THEY HAD ON THE LOT AND SAID THAT THEY ARE SIMILAR TO MINE AND THEY WAS NOT GOING TO DO ANY MORE TO MY TRUCK THAT THEY HAD DONE ALL THEY COULD OR WOULD DO BUT IF I HAD ANY OTHER PROBLEMS TO BRING IT BACK. *TR
