2005 GMC Sierra 1500

I'M CURRENTLY AT 84,000 MILES ON MY 2005 GMC SIERRA, AND WHEN STOPPED WITH THE TRUCK IN PARK MY SPEEDOMETER IS SHOWING 90MPH THEN PROCEEDS UP FROM THERE WHILE DRIVING. I THINK THERE'S SOMETHING THAT NEEDS TO BE DONE. I HAVE SEVERAL FRIENDS WITH THE SAME YEAR MODEL VEHICLES MANUFACTURED BY GM. ALL HAVE THE SAME PROBLEMS. TALKED TO A DEALER ABOUT GETTING IT FIXED THEY TOLD ME IT WAS GOING TO COST 300 FOR THE PART, AND 200 DOLLARS TO HAVE IT PROGRAMMED.... *TR

THERE IS A KNOWN ISSUE WITH GMC VEHICLES WHERE THE ODOMETER QUITS WORKING AFTER 70,000 MILES. THERE IS, I BELIEVE, A RECALL ON THE 2003/2004 MODEL YEAR. I HAVE A 2005 GMC PICKUP THAT HAS THE EXACT SAME PART IN IT AS IS ALSO DEFECTIVE. IT GIVES INACCURATE READINGS OR PEGS AT 120 OR 0. THIS IS VERY DANGEROUS. IF IT WASN'T SO EXPENSIVE, I'D FIX IT MYSELF. BUT THIS IS A DEFECTIVE PART PUT IN THE VEHICLE BY GM AND SHOULD BE FIXED BY GM. *TR

I HAVE A 2005 GMC SIERRA Z71, ABOUT TWO WEEKS AGO I WAS DRIVING IN THE COUNTRY ONLY TO GLANCE DOWN AND SEE 95 MILES PER HOUR, I BRAKED HARD ONLY TO REALIZE I WASN'T GOING THAT FAST. AFTER PULLING OVER TO THE SIDE OF THE ROAD I NOTICED MY SPEEDOMETER READ 35 AT A COMPLETE STOP. SINCE THEN IT HAS WORKED SOME DAYS OTHER DAYS IT WILL NOT READ BEYOND 50 MILES PER HOUR OR IT WILL BE SOME BIZARRE READING. I HAVE OWNED THE TRUCK FOR 3YRS 6 MONTHS IT HAS AROUND 31,500 MILES UNDER MILEAGE WARRANTY OF 36,000 MILES BUT 6 MONTHS PAST THE TIME WARRANTY. *TR

I OWN A 2005 GMC SIERRA AND THE SPEEDOMETER HAS FAILED. I OWN A GPS SO I USE THIS TO HELP DETERMINE THE SPEED I AM TRAVELING. I BROUGHT MY VEHICLE INTO THE DEALER ON SEVERAL OCCASIONS AND CONTACTED GM AND THEY STATED THEY COULD NOT HELP ME THAT I WOULD HAVE TO PAY $380.00 TO GET IT REPAIRED. TWO DAYS AFTER BRINGING INTO MY LOCAL DEALER I RECEIVED A LETTER IN THE MAIL STATING THERE WAS A CLASS ACTION LAWSUIT AGAINST GM FOR DEFECTIVE SPEEDOMETERS ON CERTAIN MAKES AND MODELS. *TR

TL*THE CONTACT OWNS A 2005 GMC SIERRA 1500. WHILE DRIVING APPROXIMATELY 5 MPH, THE CONTACT RELEASED THE ACCELERATOR PEDAL IN ORDER FOR THE VEHICLE TO COAST. THE VEHICLE THEN STALLED. SHE SHIFTED THE GEAR FROM DRIVE INTO NEUTRAL AND RESTARTED THE VEHICLE. LATER THAT WEEK, THE SPEEDOMETER DISPLAYED 55 MPH WHILE THE VEHICLE WAS IN PARK. WHILE DRIVING TO HER PLACE OF BUSINESS, THE SPEEDOMETER DISPLAYED 100-120 MPH. LATER THAT DAY, THE CONTACT DROVE THE VEHICLE TO THE DEALER AND WAS INFORMED TO BRING IT BACK FOR A DIAGNOSTIC AND REPAIR. THE MANUFACTURER HAS NOT BEEN NOTIFIED. THE CURRENT MILEAGE WAS 72,500 AND FAILURE MILEAGE WAS 72,300. UPDATED 2/2/09 *CN THE CONSUMER STATED THE SPEEDOMETER BECAME STUCK AT 47 MPH AT STARTUP. THE CONSUMER STATED HE DID NOT KNOW HOW FAST HE WAS DRIVING, SINCE THE SPEEDOMETER WAS INOPERATIVE. UPDATED 02/04/09. *JB
