NHTSA Complaint #10689863 — 2007 GMC YUKON

WHILE MY WIFE WAS DRIVING ON THE INTERSTATE HIGHWAY AT 55MPH, THE SUV CHECK ENGINE LIGHT CAME ON, FOLLOWED BY A TRACTION CONTROL WARNING ON THE DISPLAY, THEN THE VEHICLE WENT INTO "LIMP MODE", REDUCING POWER AND SPEED TO APPROX 20 MPH. SHE TURNED ON THE HAZARDS, AND MOVED INTO THE RIGHT LANE AS OTHER VEHICLES WENT AROUND HER AT THE POSTED SPEED LIMIT AS THE ENGINE WAS BUCKING AND MISSING. SHE EXITED THE HIGHWAY AND LIMPED THE TRUCK, BARELY GETTING UP TO 20 MPH TO A SERVICE SHOP. THEY SCANNED THE CODES, THE ONLY ONE THERE DIRECTED THEM TO CHANGE THE THROTTLE BODY, ($580). THE VEHICLE RAN GOOD FOR 3 DAYS, THEN ALL THE SAME BELLS AND WHISTLES CAME BACK. GMC SERVICE SAID THEY HAVE NO KNOWLEDGE OF A PROBLEM. UPON RESEARCHING THIS ONLINE, I FOUND IT'S FAR FROM UNCOMMON. IF THIS HAS NOT CAUSED AN ACCIDENT YET, ITS ONLY A MATTER OF TIME.. *TR
