NHTSA Complaint #10914960 — 2003 GMC YUKON XL

INSTRUMENT CLUSTER. GAUGES RANDOMLY STICK OR FALSELY READ TO INCLUDE SPEEDOMETER. SOMETIMES IT WILL STICK AT A RANDOM SPEED. OTHER TIMES IT WILL PEG AT ITS MAX. UNKNOWN IF ODOMETER IS INVOLVED. SOMETIMES THEY RESET AFTER REPEATED START/OFF CYCLES. WAS COVERED UNDER A GM RECALL BULLETIN NO: 07187B, PAGE 8. CURRENT ODOMETER IS 145,369. SHOULD GM NOT REPAIR THIS AFTER THE WARRANTED PERIOD? THIS IS JUST AS DANGEROUS NOW THAN IT WAS AT 70,000 MILES. OIL PRESSURE GAUGE VERY RARELY READS CORRECTLY. I TRAILER TOW OFTEN AND CORRECT OIL PRESSURE IS IMPERATIVE AS IS A CORRECT SPEEDOMETER READING. ON THE TOP OF THE PAGE I DOWNLOADED FROM NHTSA IS THE NUMBER CSC-10026542-8984. PLEASE NOTE THAT THIS BEGAN TWO YEARS AGO WITH A FAULTY AMP GAUGE BUT WITHIN THE LAST SEVERAL MONTHS IT HAS NOW AFFECTED ALL GAUGES BUT THE FUEL GAUGE, WATER TEMP AND TRANSMISSION TEMP. POSSIBLY RELATED IS THE HEATED SEAT ON THE DRIVERS SIDE. THE HEAT IS ON ALL THE TIME (ON HI) AND CAN ONLY BE SHUT OFF BY UNPLUGGING THE SEAT WHICH DEACTIVATES THE AIR BAG SENSOR, POWER SEAT CONTROL AND THE LIKE. I HAVE NOT CONTACTED GM AT THIS TIME. PLEASE ADVISE ME AS TO MY COURSE OF ACTION.
