2003 GMC SIERRA Power Train Problems

I WAS PARKED ON A SLOPED DRIVEWAY (ABOUT 10 - 15 DEGREES). I STARTED THE ENGINE, STEPPED ON THE BRAKE PEDAL AND TOOK THE CAR OUT OF PARK INTO DRIVE. BRAKE PEDAL WAS NORMAL. I STARTED TO ROLL FORWARD AND WHEN I PUSHED THE BRAKE PEDAL THE CAR DID NOT SLOW. I SLAMMED THE BRAKE PEDAL AND IT WENT ALL THE WAY TO THE FLOOR. AT THIS POINT I WENT OFF THE END OF THE DRIVEWAY ONTO A 45 DEGREE DOWNWARD SLOPED LAWN; THEN INTO A WOODED AREA AT THE TOP OF A RAVINE. I SLAMMED INTO A TREE. THE CAR WAS JUDGED A TOTAL LOSS BY MY INSURANCE COMPANY. I DID NOT GET A BRAKE WARNING LIGHT. THE AIRBAGS DID NOT DEPLOY. THE CAR WAS SERVICED AT A UNION PARK GMC (WILMINGTON, DE) TWO DAYS PRIOR. INCLUDING BRAKE INSPECTION. CAUSE OF BRAKE FAILURE WAS DETERMINED TO BE RUPTURED BRAKE...

ON FEBRUARY 18, 2003 I PURCHASED A NEW 2003 TRUCK THE TRUCK CAME WITH THE SERVICE LIGHT ON. WHEN DRIVING THE 4X4 WHEEL LIGHT WOULD COME ON AS IF THE TRUCK WAS IN 4 WHEEL DRIVE. THE LIGHT WOULD GO OFF AFTER STOPPING AND SHUTING THE TRUCK OFF FOR AT LEAST 15 MINUTES. I WENT TO THE DEALER AND THEY SAID THERE WAS NO FIX AT THIS TIME AND THEY GAVE ME A SERVICE BULLETIN, FILE IN SECTION:4-DRIVELINE AXLE BULLETIN NO:03-04-21-001 DATE: FEBRUARY, 2003. I WAS TOLD THAT IF I WAS WORRIED ABOUT THE 4X4 ENGAGING ON ITS OWN WHILE DRIVING THE ONLY THING THEY COULD DO WAS TO DISENGAGE THE 4X4 WHEEL DRIVE AT THIS TIME.I NEED TO HAVE THE USE OF THE 4X4 WHEEL DRIVE AS I OWN A LARGE CONCRETE CONSTRUCTION COMPANY AND USE MY TRUCK ALL DAY LONG ON JOBSITES. I LEFT THE DEALER NOT KNOWING...

ON MAY 31ST, THE REAR END DIFFERENTIAL ASSEMBLY EXPLODED SENDING THE PINON THRU THE HOUSING AND THE REAR AXLE CAUGHT ON FIRE. THE TRUCK WAS IN THE SHOP (PERRY CHEVEROLET, INC., COLUMBIA, MO)UNTIL 6-9-03. WHEN I ARRIVED IN BOZEMAN, MT ON 7-2-03 I WAS HAVING PROBLEMS WITH THE WIRING. THERE WAS A FIRE WHEN I PLUGGED THE RV ELECTRICAL PLUG INTO THE TRUCK'S TRAILER PLUG. THERE WAS ALSO A BLOWN REAR TAIL LIGHT BULB. IN BOZMAN, THEY REPLACED THE COMPLETE WIRING HARNESS, THE TOW RECEPTACLE AND 2 FUSE KITS. IT WAS THE OPINION OF THE SHOP IN BOZEMAN (J.C.BILLION, GMC) THAT THE WIRING DAMAGE WAS PART OF THE ORIGINAL FIRE AND DIFFERENTIAL ASSEMBLY DAMAGE. ALTHOUGH GMC PAID FOR MY OUT OF POCKET EXPENSES AND FOR THE WARANTY WORK, I AM LEFT TO WONDER WHAT WILL HAPPEN NEXT AND JUST HOW SAFE AM I GOING TO BE IN THIS TRUCK? I...

THE VEHICLE SHIFTED INTO 4 LOW WITHOUT WARNING. *JB
