NHTSA Complaint #10298655 — 2004 GMC SIERRA 2500

2004 GMC SIERRA SLT DURAMAX 2500HD. 92,000 MILES. WELL -MAINTAINED. WITH NO WARNING SPEEDOMETER READ FORTY MILES TOO LOW. WE THOUGHT WE WERE ENTERING THE FREEWAY AT 60, WHILE IN FACT WE WERE GOING 20. WE ALMOST GOT RAMMED BY A TRUCK. IT IS ILLEGAL TO GO 20 ON AN INTERSTATE. THIS REQUIRED SPEEDOMETER CLUSTER REPLACEMENT COSTING $529. GM REFUSED ANY COVERAGE OF THE COST. I SUGGESTED THEY COVER HALF THE CLUSTER PART, $175. THEIR CUSTOMER SERVICE SAID, "NO." IF THERE IS A SAFETY ISSUE, THIS WOULD BE IT! I UNDERSTAND THERE ARE SEVERAL LAWSUITS REGARDING THESE SPEEDOMETERS. OUR VIN IS ON THEIR "SILENT RECALL" LIST. NATIONAL HIGHWAY SAFETY TRAFFIC ADMINISTRATION SHOULD BE RESPONSIBLE FOR ISSUING OPEN ENDED RECALLS FOR SAFETY ITEMS SUCH AS THESE. THE MISSION IS TO PROTECT THE PUBLIC? *TR
