NHTSA Complaint #10339522 — 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
