WE HAVE A 2004 GMC YUKON. SINCE WE'VE HAD IT, REDUCED ENGINE POWER HAS BECOME A CONSTANT AND DANGEROUS PROBLEM. MOST RECENTLY, YESTERDAY, MY HUSBAND WAS TRYING TO ACCELERATE TO PASS A SLOWER VEHICLE WITH HUGE TIRES ON THE BACK ONLY TO HAVE THIS HAPPEN. IF SOMEONE HAD BEEN BEHIND US, WE WOULD HAVE BEEN HIT, SERIOUSLY INJURED, MAYBE EVEN DEAD WITH SOME OF THE CIRCUMSTANCES WE HAVE HAD ON THE INTERSTATE. TODAY IS AUGUST 23, 2011. WE HAD THIS VEHICLE FIXED ON JULY 28, 2011, PAYING ALMOST $600 FOR IT TO BE TAKEN CARE OF. IT SAYS ON THE TICKET THAT WE TOLD THEM ABOUT IT AND WERE UNDER THE IMPRESSION THIS WOULD TAKE CARE OF IT. THEY REPLACED THE ACCELERATOR PEDAL ASSEMBLY, WHICH I BELIEVE INCLUDED THE APP SENSOR, AND CLEANED THE THROTTLE BODY OF EXCESSIVE CARBON BUILD UP. AFTER SPENDING $500-600, I WANT TO KNOW WHY WE ARE STILL HAVING THIS PROBLEM ALONG WITH SO MANY OTHERS I HAVE SEEN COMPLAIN ABOUT IT ONLINE? GMC HAS A KNOWN PROBLEM THAT NEEDS TO BE RESOLVED. *TR

FAULTY SPEEDOMETER 2005 GMC YUKON. I RECENTLY SAW A NEWS REPORT ON FAULTY SPEEDOMETERS WITH GM VEHICLES DONE BACK IN 2007 AND I AM EXPERIENCING THE SAME PROBLEM WITH MY 2005 GMC YUKON. CURRENTLY MY SPEEDOMETER SITS AT 60 MPH IN PARK AND GETS PINNED AT 120 MPH ON THE ROAD WHEN I'M ONLY MOVING AROUND 40 MPH. I HAVE CONTACTED GMC AND THEY TOLD ME THE WARRANTY ON THIS PROBLEM IS 5 YRS OR 70,000 MILES. ONE PROBLEM, I AM AT 91,000 MILES AND THEY TOLD ME GMC MAILED OUT LETTERS STATING THE SPEEDOMETER PROBLEMS. I NEVER RECEIVED THIS LETTER!! NOW THEY ARE OFFERING TO FIX THE PROBLEM FOR $600!! I HAVE ALSO CONTACTED GM CUSTOMER HELP LINE AND THE SAID THE SAME THING. MY QUESTION IS IF GMC ADMITS TO THE FAULTY SPEEDOMETER THEN WHY DID THEY PUT A 70,000 MILE CAP ON THE WARRANTY FOR THIS ISSUE WHICH IS CLEARLY A SAFETY HAZARD?? COULD YOU PLEASE HELP? ALSO DO YOU HAVE ANY ADVICE WITH THIS ISSUE? THANK YOU FOR YOUR HELP AND FOR LOOKING OUT FOR THE CONSUMER. *TR
