NHTSA Complaint #10569093 — 2007 GMC YUKON DENALI

I HAVE JUST READ A FEW OTHER COMPLAINTS ABOUT AN ISSUE I AM HAVING NOW, AND HAVE HAD 3 TIMES IN THE PAST. WHILE UNDER NORMAL DRIVING CONDITIONS, I HAVE HAD MY SUV BECOME VERY SLUGGISH AND DIFFICULT TO DRIVE. LIGHTS COME ON SAY LOSS OF POWER, STABILITRAC PROBLEM ETC. THE FIRST TIME THIS HAPPENED, I WAS VISITING ORLANDO FLORIDA. I TOOK THE SUV TO A DEALER, AND THEY SAID THERE WAS AN ISSUE WITH THE ECM AND REPROGRAMMED IT. I LEFT BACK THE NEXT DAY FOR ATLANTA. NEARLY 80 MILES AWAY IN OCALA FLORIDA, IT STARTED DOING THIS AGAIN. I CALLED A TOW TRUCK, AND HAD IT TAKEN TO AN OCALA DEALERSHIP. THEY IN TURN TOLD ME IT WAS A BAD ECM, AND AFTER SPENDING AN ENTIRE DAY IN OCALA, I WAS BACK ON MY WAY TO ATLANTA. SEVERAL MONTHS LATER, I HAD THIS OCCUR AGAIN. ONCE AGAIN I HAD IT TAKEN TO A DEALERSHIP IN ATLANTA. THEY RAN A COMPUTER DIAGNOSIS ON IT, AND SAID THEY HAD NO IDEA WHY IT WAS DIAGNOSED AS AN ECM PROBLEM, AS THE CODE COMING UP WAS DUE TO A PROBLEM WITH THE SENSOR IN THE FLOOR BOARD THAT READS THE DISTANCEOF THE GAS PEDAL FROM THE FLOOR BOARD. AS IT IS A DRIVE BY SENSOR VS DRIVE BY WIRE. THEY REPAIRED THIS, AND ALTHOUGH I FELT IT SHOULD HAVE BEEN COVERED UNDER WARRANTY, EVEN THOUGH I WAS OUT OF WARRANTY AT THE TIME, THE FIRST TWO INCIDENTS THAT WERE SUPPOSEDLY DIAGNOSED WRONG WERE DONE SO WHILE UNDER WARRANTY. THEY ENDED UP CUTTING THE COSTS IN HALF. I HAD NO CHOICE, AS I NEEDED MY VEHICLE BACK. NOW IT HAS OCCURRED THE FORTH TIME. I HAVE RESORTED TO THE INTERNET TO SEE IF OTHER ARE HAVING THE SAME PROBLEM. WHAT I'M FINDING THROUGH THIS RESEARCH, IT SOUNDS AS IF MANY HAVE HAD THE SAME ISSUE, AND IT SEEMS TO BE AN ISSUE WITH THE THROTTLE BODY. WHILE RESEARCHING, I WAS ALERTED TO THIS SITE, THUS THE REASON I'M POSTING HERE. MAYBE SOMETHING CAN BE DONE ABOUT THIS ISSUE, AS IT SEEMS THIS HAPPENS QUITE OFTEN, AND GMC IS KEEPING IT UNDER WRAPS. *TR
