I OWN A 2005 GMC SIERRA 2500HD PICKUP. THE SPEEDOMETER ON THIS VEHICLE IS STARTING TO GO BAD AND WHEN I AM DRIVING DOWN THE HIGHWAY IT WILL GRADUALLY LOOSE INDICATED SPEED AND THEN EVENTUALLY GO TO ZERO. I AM AWARE THAT THERE IS CURRENTLY A RECALL OUT FOR THIS TYPE OF PROBLEM, BUT I HAD MY VEHICLE IN THE SHOP AND FOR SOME REASON MY VIN # DOES NOT FALL INTO THE RECALL LIST SO I HAVE NOT GOT IT REPAIRED AT THIS TIME. THE RECALL DOCUMENT THAT I FOUND IS #07187C: SPECIAL COVERAGE ADJUSTMENT - INSTRUMENT PANEL CLUSTER GAUGE NEEDLE FUNCTION -(MAR 20, 09), MY QUESTION IS THAT DOES YOUR AGENCY UPDATE THIS LIST FREQUENTLY OR ONCE IT IS OUT THAT IS ALL THAT WILL BE COVERED? *TR

SUDDEN PROBLEMS WITH SPEEDOMETER. SPEEDOMETER STARTS AT BETWEEN 35 AND 60 MPH AT A COMPLETE STOP THEN GOES UP FROM THERE WELL PAST 120MPH WHEN TRAVELING NO FASTER THEN 60MPH. ALSO DOES NOT MOVE SMOOTHLY BUT RATHER VERY JUMPY. THIS IS A VERY WELL MAINTAINED TRUCK WITH 54K MILES ON IT. *TR

REPLACED EVERY MODULE IN THE HEATER SYSTEM IN MY 05 GMC SIERRA SEVERAL TIMES, AND SO HAS JUST ABOUT EVERYONE ELSE I KNOW WHO OWNS ONE. NOW MY WIRING HARNESS BURNED WITHOUT BLOWING ANY FUSES. GM SHOULD HAVE A RECALL ON THIS, AND FIND THE PROBLEMS, AND FIX THEM, BEFORE EVERYONE WHO OWNS ONE GOES BROKE REPAIRING THEM. *TR
