I WAS ON THE HIGHWAY DRIVING THROUGH BOSTON IN THE FAST LANE, GOING ABOUT 70MPH WHEN ALL OF A SUDDEN THE STABILITY CONTROL LIGHT CAME ON WITH THE CHECK ENGINE LIGHT AND THE ENGINE REDUCED POWER LIGHT AND MY VEHICLE TOTALLY LOST POWER TO THE GAS PEDAL. I WAS ABLE TO GET INTO THE SLOW LANE BUT MY VEHICLE WAS NOT ABLE TO GO FASTER THAN 35MPH AND THERE WAS HARDLY POWER TO MY GAS PEDAL. LUCKILY, I MADE IT TO AN OFF RAMP, AS I STARTED TO COME TO A STOP, THE ENGINE WAS RUNNING VERY ROUGH AND IT FELT LIKE IT WAS SHAKING THE VEHICLE BACK AND FORTH. I BARELY MADE IT INTO A EMPTY PARKING LOT AND SHUT THE ENGINE OFF. I MANAGED TO MAKE IT TO MY MECHANIC, WHO GOT A THROTTLE SENSOR CODE FROM THE ENGINE. HE TOLD ME ABOUT A SPECIAL COVERAGE ADJUSTMENT #12273B FROM GMC, REGARDING THIS EXACT ISSUE AND TOLD ME TO TAKE IT TO GMC. GMC TOLD ME, MY VEHICLE ISN'T LISTED FOR THIS ADJUSTMENT, EVEN THOUGH, IT SAYS IT SHOULD COVER 2008-20111 GMC YUKONS. APPARENTLY, GMC SAID MY VIN ISN'T LISTED AS HAVING THE FAULTY PART. I ALMOST DIED THIS MORNING IN THE FAST LANE IN BOSTON WITH THE EXACT PROBLEM GMC DESCRIBES IN THE 12273B. GMC SAID I'M NOT COVERED AND HAVE TO PAY OUT OF POCKET. ABSURD. *TR

THE SEAT CAUGHT ON FIRE WHILE THE CAR WAS RUNNING. MY CHILD WAS SLEEPING AND SMOKE WAS COMING OUT FROM UNDER HIS BOOSTER SEAT AND HIS LEGS. I CONTACTED GMC AND THEY SAID THIS HAD NEVER HAPPENED BEFORE AND WE SHOULD CONTACT OUR INSURANCE COMPANY, THOUGH, WHEN WE TOOK IT TO THE TECHNICIANS AT THE DEALERSHIP (FOR THE INSPECTION), THEY SAW WHERE TWO WIRES WERE ON TOP OF ONE ANOTHER AND THE SEAT HAD CAUGHT ON FIRE. THIS IS A SERIOUS PROBLEM. I SEARCHED ONLINE AND THERE ARE MANY STORIES OUT THERE, I AM JUST NOT SURE IF PEOPLE ARE REPORTING THEM---OR IF THEY REALIZE THAT GMC MAKES SIMILAR CARS SO CADILLAC, SIERRAS, AND OTHER CARS COME FROM THE SAME MOLD.

CAME OUT OF CARWASH AND REAR SUSPENSION LOCKED UP AND BACK OF MY VEHICLE RAISED APPROXIMATELY 8/12 INCHES LIGHT CAME ON SAID SERVICE SUSPENSION AND TRAILER BRAKING SYSTEM. VEHICLE HAS NEVER HAULED ANYTHING A BURNT SMELL CAME FROM BACK END. THIS VEHICLE HAS NEVER EVEN HIT A POTHOLE. ONLY BEEN DRIVEN LOCALLY. I'M A LITTLE FRUSTRATED BECAUSE I HAD IMMEDIATELY TAKING IT IN TO THE DEALERSHIP WHERE I PURCHASED IT. AND THEY TREATED IT LIKE IT WAS NOT A BIG DEAL. WHEN BACK IN FELT LIKE IT WAS GRABBING EVERY TIME THE BRAKE WAS APPLIED. THEY SURE DIDN'T HAVE A PROBLEM GIVING ME A $800.00 HUNDRED DOLLAR BILL ON A $63,000 THOUSAND DOLLAR BASICALLY BRAND NEW VEHICLE. I GOT ONLINE AND SAW MANY OTHERS WITH SAME PROBLEM.
