2004 GMC Sierra 1500

I RECEIVED A LETTER FROM GM STATING MY VEHICLES INSTRUMENT CLUSTER MAY GIVE FALSE READINGS. IF YOUR VEHICLE IS DOING THIS, TAKE THIS LETTER TO YOUR GM DEALER AND THEY WILL FIX THE PROBLEM IF IT'S NOT THEN YOU DON'T NEED TO. IT ALSO STATED THAT THE WARRANTY FOR THIS IS 70,000 MILES AND THEY WOULD NOT REPLACE THE CLUSTER IF IT WAS NOT GIVING FALSE READINGS. AT 93,721 MY FUEL GAUGE STARTED MALFUNCTIONING, AND AT 94,066 MILES MY SPEEDOMETER READING WAS OVER 120MPH, AND I WAS NOT EVEN MOVING. NOW WHEN I DRIVE THROUGH A SCHOOL ZONE OR NEIGHBORHOOD I HAVE NO IDEA HOW FAST I'M GOING. I DIDN'T EVEN HAVE 100,000 MILES ON THE VEHICLE WHEN THESE PROBLEMS STARTED HAPPENING. WHEN I TOOK MY VEHICLE IN TO GET IT FIXED UNDER THE WARRANTY THEY TOLD ME IT WAS OUT OF WARRANTY AND WOULD NOT COVER THE PARTS. SO MUCH FOR GMC PROFESSIONAL GRADE. THE LOGO THEY USE WHEN SELLING THERE VEHICLES ON TV. I HAVE SAVED PICTURES ON MY CELL PHONE SHOWING THE ACTUAL MILEAGE WHEN THESE FALSE READINGS OCCURRED. *TR

WHILE DRIVING NOTICED THAT I WAS GOING FASTER THAN THE SPEEDOMETER SAID. FELT LIKE I WAS GOING AT LEAST 80 WHEN THE SPEEDOMETER SAID 45 MPH. KEPT WATCHING AND WHEN I CAME TO A STOP THE METER WOULD READ BELOW ZERO. TRIED RESTARTING THE TRUCK AND IT RESET TO ZERO BUT WHILE HOLDING A SET SPEED THE METER WOULD CONTINUOUSLY DROP. NEXT DAY WORKED FINE. 2 DAYS LATER I NOTICED THE METER DROP OFF AGAIN. WHEN I SHUT THE TRUCK OFF THIS TIME IT GOT STUCK AT 30MPH. DROVE FOR A LITTLE WHILE AND TRIED SHUTTING IT OFF AND STARTING IT AGAIN THIS TIME IT STAYED AT ZERO. IT TOLD THE WIFE NOT TO DRIVE IT UNTIL IT IS FIXED. I DON'T WANT HER IN THERE WITH MY CHILD IF THERE WAS A WRECK DUE TO NOT KNOWING WHAT SPEED THE TRUCK IS REALLY GOING. *TR

AT FIRST MY SPEEDOMETER WOULD 'TICK' AND THAT LED TO IT JUMPING AROUND. IT STICKS IN VARIOUS PLACES, SOMETIMES DOWN TO THE RIGHT FAR OFF OF THE GAUGE ITSELF. MY TACHOMETER DOES THE SAME THING. IT HAS BEEN THIS WAY FOR A WHILE NOW, I JUST CAN'T WANT TO FORK OVER $600 TO GET IT FIXED. I HEARD THAT GM INFACT HAS AND UNPUBLISHED BULLETIN UNDER THEIR GOODWILL PROGRAM TO FIX IT - CAN THIS BE MADE TO BE A PUBLISHED BULLETIN? *TR

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
