NHTSA Complaint #10262034 — 2004 GMC ENVOY

MY 2004 GMC ENVOY HAS DEVELOPED AN ERRATIC SPEEDOMETER. THE SPEEDOMETER REFLECTS INACCURATE SPEEDS CAUSING AN UNSAFE DRIVING CONDITION. I CONTACTED MY LOCAL GMC DEALER WHO RESEARCHED TO FIND NO RECALL CONCERNING THIS PROBLEM I THEN SUBMITTED MY COMPLAINT TO THE BBB HOTLINE AND WAS REBUFFED THEIR ALSO. I HAVE CONSEQUENTLY DONE ADDITIONAL RESEARCH AND HAVE FOUND THAT GM HAS ISSUED A SPECIAL COVERAGE ADJUSTMENT BULLETIN FOR 2003-2004 CADILLAC ESCALADE, CHEVROLET AVALANCHE, SILVERADO, SUBURBAN AND TAHOE, GMC SIERRA AND YUKONS. THE SPEEDOMETER UNIT IN THESE MODELS ARE VERY SIMILAR IN BOTH APPEARANCE AND ARE MANUFACTURED BY THE SAME SUPPLIER GM USES. THE ADJUST BULLETIN IS #07187 DATED SEPTEMBER 28,2007 AND COVERS THE CONDITION FOR A PERIOD OF 7 YEARS OR 70,000 MILES REGARDLESS OF OWNERSHIP. AFTER VISITING MANY GMC AND CHEVROLET CHAT ROOMS IT IS READILY APPARENT THAT THIS PROBLEM IS VERY COMMON AND WILL EVENTUALLY RESULT IN A FATAL ACCIDENT. I AM REQUESTING THAT THE NHTSA FORMALLY INVESTIGATE THIS PROBLEM BEFORE THIS HAPPENS. *TR
