NHTSA Complaint #10265043 — 2003 GMC ENVOY

WITHIN THE LAST 4 OR 5 MONTHS, THE SPEEDOMETER ON OUR 2003 ENVOY WILL DISPLAY ERRATIC AND INCORRECT SPEEDS. WHEN THE VEHICLE IS FIRST STARTED UP THE SPEEDOMETER SEEMS TO REGISTER CORRECTLY. AFTER 20 MINUTES OR MORE THE NEEDLE WILL BEGIN TO STICK OR STUTTER. WITHIN 30 MINUTES THE SPEEDOMETER WILL REGISTER 90 MPH WITH AN ACTUAL ROAD SPEED OF 60 TO 65 MPH. TODAY IT EVENTUALLY PEGGED THE NEEDLE AT 120 MPH+. AT A COMPLETE STOP, WITH THE ENGINE OFF AND KEY OUT OF THE SWITCH, THE SPEEDOMETER REGISTERED 60 MPH. WE ARE MAKING CONTACT WITH OUR LOCAL GMC DEALER TO SEE WHAT REPAIRS WILL BE INVOLVED. BASED ON SEVERAL INTERNET FORUM SITES AND CHAT BOARDS, THIS IS NOT AN UNCOMMON PROBLEM. IT ALSO APPEARS THAT GM HAS NOT ISSUED A RECALL FOR THIS PROBLEM. THEY EVIDENTLY DO NOT SEE THIS AS A SAFETY PROBLEM OR POTENTIAL SAFETY PROBLEM. OUR ENVOY HAS LESS THAN 67,000 MILES ON THE ODOMETER. *TR
