The contact confirmed through the Carfax Report that the actual mileage was 300,000.

ABOUT A MONTH A AGO MY 2003 YUKON XL ALL OF A SUDDEN WOULD NOT DRIVE OVER15 MILES AN HR IN RUSH HOUR TRAFFIC. I TOOK THE TRUCK TO THE SHOP TO HAVE DIAGNOSTICS RAN. I WAS TOLD IT WAS THE BATTERY. THE TRUCK RAN FOR ABOUT A MONTH THEN ALL OF A SUDDEN THE BATTERY WAS BACK DEAD. RETURNED THE TRUCK BACK TO THE SHOP ANOTHER BATTERY WAS PUT IN. IT'S BEEN ABOUT ANOTHER MONTH. THIS TIME I WAS DRIVING FROM MIAMI TO JACKSONVILLE AND THE TRUCK LOST POWER 100 MILES OUTSIDE JACKSONVILLE ON I-95 NORTH. IT HAD ALL POWER JUST WOULD NOT CRANK. HAD IT TOWED TO THE SHOP NOW I'M BEING TO THERE'S A PROBLEM WITH ELECTRICAL.

VEHICLE RANDOMLY GOES INTO REDUCE ENGINE POWER MODE AND STALLS WHILE DRIVING. THIS HAS HAPPENED MULTIPLE TIMES WHILE DRIVING ON A HIGHWAY AND GOING UP A HILL WHERE IT NEARLY CAUSED A THREE CATASTROPHIC ACCIDENTS. BASIC RESEARCH SHOWS THAT GM HAS KNOWN ABOUT THIS ISSUE SINCE THE VEHICLES WERE A FEW YEARS OLD AND IT AFFECTS MANY YEARS OF GM VEHICLES. THERE IS A PROBLEM WITH BAD GROUNDING CONNECTORS RELATED TO THE THROTTLE BODY SENSOR AND AND WIRING HARNESS.

BRAKE LINES CORRODED RESULTING IN LOSS OF BRAKES AND REAR ENDING SCHOOL BUS. REPLACED ALL BRAKE LINES AT MY COST AS WELL AS THE DAMAGE TO THE FRONT END OF THE TRUCK. NOW, THE KNOWN ABS BRAKE SENSOR ISSUE IS ACTIVATING THE ABS AT LOW SPEEDS.

TL* THE CONTACT OWNS A 2003 GMC YUKON XL. WHILE DRIVING 35 MPH, THE STABILITY CONTROL FAILED AND THE VEHICLE LOST POWER. THE STABILITY CONTROL ACTIVE WARNING INDICATOR ILLUMINATED. THE VEHICLE WAS NOT DIAGNOSED OR REPAIRED. THE CONTACT MENTIONED THAT THERE WAS ALSO A GRINDING SOUND. THE MANUFACTURER WAS NOT MADE AWARE OF THE FAILURES.

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.
