2003 GMC Sierra Powertrain (other) 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 LINE. BOTH FRONT AND REAR BRAKES WERE FAILED. *TR

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 SELECTED A TRUCK BIGGER THAN WHAT I NEEDED AT THE CURRENT TIME, THINKING THAT IF I REPLACED MY TRAVEL TRAILER IN THE FUTURE, I WOULD NOT HAVE TO TRADE TRUCKS ALSO.

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 WHAT TO DO. I WAS WORRIED ABOUT DAMAGING THE 4X4 UNIT EVEN MORE ON MY NEW TRUCK. SO TWO WEEKS LATER I WAS TIRED OF WORRYING, SO I TOOK THE TRUCK BACK TO THE DEALER AND THEY DISENGAGED THE 4 WHEEL DRIVE. THE SERVICE 4X4 WHEEEL LIGHT IS STILL ON AT THIS TIME. I ALSO FILED A COMPLAINT WITH GMC ON 3/27/03 #1-85090755. I HAVE NOT HEARD FRON THE DEALER IN ONE MONTH.

I OWN A 2003 GMC SIERRA 1500 Z71 OFF ROAD TRUCK. I'VE HAD IT IN THE SHOP FOUR TIMES NOW DUE TO THE SAME PROBLEM. THE PROBLEM CONSISTS OF EXCESSIVE PLAY/BACKLASH IN THE REAREND/DIFFERENTIAL ACCORDING TO THE DEALER. THIS EXCESSIVE PLAY/BACKLASH IS CAUSING THE TRUCK TO JERK AFTER SHIFTING FROM FIRST TO SECOND AND SECOND TO THIRD GEARS. THE DEALER AND MANUFACTURER SAY THIS IS NORMAL ACCORDING TO GM SPECS. AT ONE POINT, WHILE SITTING AT A TRAFFIC LIGHT, I PROCEEDED TO ACCELERATE AFTER THE LIGHT TURNED GREEN AND THE TRUCK DIDN'T GO ANYWHERE, BUT AFTER A FEW SECONDS THE TRUCK SLAMMED INTO GEAR AND SPUN THE REAR TIRES. THIS PROBLEM SEEMS TO HAVE BEEN CORRECTED AFTER REPLACING THE TRANSMISSION CONTROL SOLENOID FOR NOW, BUT THE CONSTANT JERKING OF THE REAREND/DIFFERENTIAL SEEMS TO BE WORSENING. WHEN DISCUSSING THIS PROBLEM WITH THE DEALERS SERVICE MANGER AND NOW FINALLY WITH THE GENERAL MANGER, THEY STILL SAY THIS IS NORMAL AND HAS BEEN FOR ALL 2000 THROUGH 2004 GMC SIERRA'S. THAT'S INTERESTING, BECAUSE I OWNED TWO 2000 GMC TRUCKS IN THE PAST AND NEITHER ONE OF THEM EXPERIENCED THESE PROBLEMS.

I TOOK TO DEALER, THEY ADJUSTED TIRE AIR PRESSURE. 2ND TIME IN THEY CHANGED BEARING IN FRONT DIFFERENTIAL, 3RD TIME IN THEY CHANGED FRONT DIFFERENTIAL CARRIER, THIS GOT RID OF VIBRATION, I STILL HAVE A CONCERN THAT THE CARRIER COME AS A SHELL SO IT STILL HAS ORIGINAL RING AND PINION. DON'T NO IF THIS WILL CREATE A PROBLEM LATER OR NOT BUT GEAR PATERN MUST HAVE CHANGED. *AK
