2004 GMC SIERRA 1500 Complaints

I HAVE A PROBLEM WITH MY SPEEDOMETER. EVERY DAY AFTER DRIVING IT FOR 30 +/- MILES THE SPEEDOMETER STOPS. SOMETIMES AT 50 SOMETIMES AT 0 MPH. ONCE I BEGIN TO DRIVE IT WILL SOMETIMES GO FROM 50 TO 100 OR IT WILL STAY WHERE IT STOPPED. THIS STARTED ABOUT 18 MONTHS AGO BUT IT ONLY HAPPENED ONCE EVERY COUPLE MONTHS. NOW IT HAPPENS DAILY. I HAVE LEARNED THAT AFTER LEAVING IT SET FOR A FEW HOURS I START IT UP, PUT IT INTO DRIVE AND TURN IT OFF. WITH THE GEARSHIFT IN DRIVE I TRY STARTING IT AND EACH TIME I TURN THE KEY THE SPEEDOMETER GOES FROM 50 TO 40 TO 30 AND THEN BACK TO 0. ONCE AT ZERO I START THE TRUCK AND THE SPEEDOMETER WILL BE ACCURATE FOR AT LEAST 30+/- MILES. *TR

SPEEDOMETER READS 30 MPH OVER WHAT IT SHOULD. NOT ONLY THAT, THE 4WD SENSOR WHEN OUT. ONLY USED 4WD LESS THAN 10 TIMES. TRUCK HAS LESS THAN 51K MILES. *TR

I TOOK IT TO MY MECHANIC AND HE SAYS THAT GM PARTS WILL COST APPROXIMATELY $600 AND THAT THIS IS AN EXTREMELY COMMON PROBLEM THAT THE DEALER SHOP SAYS HE SEES SEVERAL TIMES A WEEK ON THIS MODEL OF PICKUP. USING MY GPS FOR SPEED MONITORING SINCE I DON'T WANT TO PAY GM AN EXORBITANT REPAIR FEE FOR SOMETHING THEY AREN'T STANDING BEHIND. *TR

WIRING HARNESS REPLACED BY GM SERVICE DEPARTMENT. I CAN SEE THAT THE NEW WIRING HARNESS ALSO COMES INTO CONTACT WITH ARM OF PARKING BRAKE PEDAL! I HAVE THE OLD PART.

NOTICED I STARTED TO GET A VIBRATION IN THE STEERING WHEEL, TOOK IT TO THE DEALER AND THEY INSTALLED AN TBS LUBE KIT IN THE STEERING SHAFT. ABOUT A YEAR LATER THE VIBRATION IS BACK AND WORSE THAN BEFORE, CALLED THE DEALER AND THEY TOLD ME IT WOULD COST ME 300.00 PLUS LABOR. THIS IS A KNOWN PROBLEM WITH CERTAIN YEAR GM TRUCKS, AND EVERY DAY IT SEEMS TO GET WORSE. I FEEL MY SAFETY MIGHT BE COMPROMISED, IF I CONTINUE TO DRIVE IT. *TR
