AT APPROXIMATELY 66,000 MILES ON MY 2005 GMC SIERRA 1500, THE SPEEDOMETER STARTED READING 70 MPH WHILE THE TRUCK WAS STOPPED, AND ROSE FROM THERE AS IT ACCELERATED. THE CONDITION PERSISTED FOR ABOUT ONE WEEK; EACH TIME THE TRUCK WAS RESTARTED, THE SPEEDOMETER RESET ITSELF TO A LOWER STARTING SPEED, UNTIL IT READ ZERO AGAIN WHEN STOPPED. IT IS BEHAVING NORMALLY NOW, BUT THIS SEEMS TO BE A RECURRING ISSUE WITH THIS VEHICLE, AND GM HAS NOT PROVIDED OTHER OWNERS ANY RELIEF IF THE VEHICLE IS PAST ITS WARRANTY PERIOD. SOMETHING AS BASIC AND NECESSARY TO DRIVING SAFETY AS SPEEDOMETER FUNCTION SHOULD, IN MY OPINION, BE DESIGNED TO LAST THE VEHICLE'S ENTIRE INTENDED LIFESPAN WITHOUT SYSTEMIC FAILURE. *TR
