NHTSA Complaint #10373152 — 2005 GMC ENVOY

SPEEDOMETER STUCK AT 60MPH WHILE TRAVELING. DIDN'T MATTER IF STOPPED, ACCELERATING, DECELERATING, OR TURNING VEHICLE OFF. TURNING OFF THE CAR AND RESTARTING IT SEEMED TO CAUSE THE SPEEDOMETER TO DECREASE, SOME, FINALLY GETTING IT TO REGISTER 20MPH. UPON RESTARTING THE VEHICLE IN THE MORNING THE SPEEDOMETER STILL REGISTERED 20 MPH AND UPON ACCELERATION THE SPEEDOMETER FLUCTUATED FINALLY SETTLING AT 80MPH. WE WERE UNABLE TO TELL HOW FAST WE REALLY ARE TRAVELING BECAUSE THE SPEEDOMETER IS WACKO. STOPPING AND TURNING OFF THE VEHICLE DOES NOT HELP. THE SPEEDOMETER DOES NOT RESET TO ZERO IT IS NOW STUCK AT 80MPH. OUR LOCAL GM DEALER ADVISED THAT NO RECALL HAS BEEN ISSUED BUT AN EXTENDED WARRANTY TO 75,000 MILES WAS OFFERED ON THE VEHICLE FOR THIS PARTICULAR PROBLEM. OUR VEHICLE IS OVER THE MILEAGE FOR THE WARRANTY. GM IS AWARE THERE IS A PROBLEM WITH WACKO SPEEDOMETERS HENCE THE WARRANTY EXTENSION. ONE WOULD ASSUME BEING ABLE TO MONITOR ONES SPEED IN A VEHICLE IS AN IMPORTANT SAFETY CONCERN. *TR
