2000 GMC C Series

IN A LETTER DATED APRIL 20, 2005, GM NOTIFIED NHTSA THAT IT HAD DECIDED THAT DEFECTS THAT RELATE TO MOTOR VEHICLE SAFETY EXIST IN CERTAIN MODEL YEAR (MY) 1999-2002 C/K 1500 SERIES (PBR PARKING BRAKE SYSTEM) AND MY 2001-2005 C/K 2500 AND 3500 SERIES (TRW PARKING BRAKE SYSTEM) PICKUPS WITH MANUAL TRANSMISSIONS.ACCORDING TO GM, SOME OF THESE VEHICLES MAY HAVE CONDITIONS THAT CAUSE THE FRICTION LININGS TO WEAR TO AN EXTENT WHERE THE PARKING BRAKE CAN BECOME INEFFECTIVE IN IMMOBILIZING A PARKED VEHICLE.GM'S ACTION COVERS AN ESTIMATED TOTAL OF 142,585 VEHICLES.DEALERS WILL INSTALL A LOW-FORCE SPRING CLIP RETAINER FOR VEHICLES EQUIPPED WITH THE PBR PARKING BRAKE SYSTEM AND INSTALL A REDESIGNED PARKING BRAKE CABLE ASSEMBLY ON VEHICLES EQUIPPED WITH THE TRW PARKING BRAKE SYSTEM. A TOTAL OF 58 NON-DUPLICATIVE COMPLAINTS WERE RECEIVED BY ODI AND GM CONCERNING THE APPROXIMATELY 59,000 MY 1999-2002 C/K 1500 SERIES PICKUP TRUCKS WITH THE PBR PARKING BRAKE SYSTEM.THESE INCLUDED 22 ALLEGED ROLLAWAY INCIDENTS, RESULTING IN A RATE OF 38.5 ROLLAWAY INCIDENTS PER 100,000 VEHICLES.ODI IS AWARE OF 24 COMPLAINTS REGARDING THE MY 2001-2005 C/K 2500 AND 3500 SERIES MANUAL TRANSMISSION TRUCKS RECALLED BY GM, INCLUDING 5 ALLEGING ROLLAWAY INCIDENTS.THOUGH THE CONDITIONS DESCRIBED IN GM'S LETTER ARE ALSO PRESENT IN THE C/K TRUCKS WITH AUTOMATIC TRANSMISSIONS, THE ROLLAWAY RATE IN THOSE VEHICLES WAS SIMILAR TO THOSE OBSERVED IN PEER VEHICLES STUDIED BY ODI IN THIS INVESTIGATION.THIS ENGINEERING ANALYSIS IS CLOSED. FOR ADDITIONAL INFORMATION, SEE THE ATTACHED CLOSING REPORT.

ODI OPENED PE03-057 TO ASSESS PARKING BRAKE INEFFECTIVENESS IN THE SUBJECT VEHICLES.THESE VEHICLES ARE EQUIPPED WITH FOUR WHEEL DISC BRAKES THAT INCORPORATE A SINGLE-SHOE DRUM-IN-HAT PARKING BRAKE INDEPENDENT OF THE SERVICE BRAKES.COMPLAINT AND WARRANTY DATA INDICATE THAT THE PARKING BRAKE LININGS TEND TO WEAR OUT EARLY IN THE LIFE OF THE VEHICLE (AT AN AVERAGE OF 24 MONTHS IN SERVICE), REDUCING THE PARKING BRAKE SYSTEM'S TORQUE BELOW THAT NEEDED TO IMMOBILIZE THE VEHICLE.GM HAS ATTRIBUTED THIS ACCELERATED WEAR TO FOREIGN MATERIAL INTRUSION AND A FAILURE OF THE BRAKE SHOE TO PROPERLY SELF-CENTER WITHIN ITS BRAKE DRUM.EFFECTIVE WITH THE START OF MY 2003 PRODUCTION, A NEWER REDUCED FORCE HOLD-DOWN CLIP WAS INTRODUCED TO FACILITATE BRAKE SHOE DISENGAGEMENT FROM THE DRUM SURFACE.THIS PART IS ALSO AVAILABLE AT THE SERVICE LEVEL FOR THE MY 1999-2002 VEHICLES.GM HAS INDICATED THAT THE PAKING BRAKE IS INTENDED TO OPERATE IN CONJUNCTION WITH THE TRANSMISSION TO IMMOBILZE PARKED VEHICLES, AND THAT IN MANY CASES, ACCELERATED PARKING BRAKE LINING WEAR IS CAUSED BY ROUGH USE, VEHICLE MODIFICATIONS, AND DRIVING WITH THE PARKING ENGAGED. ODI HAS UPGRADED THE PRELIMINARY EVALUATION TO AN ENGINEERING ANALYSIS TO GATHER FURTHER INFORMATION CONCERNING PARKING BRAKE USAGE FACTORS AND THE CIRCUMSTANCES SURROUNDING THE SEVENTEEN REPORTED VEHICLE CRASHES.

I BOUGHT EXTENDED WARRANTY WHEN I BOUGHT TRUCK. IN MAY 2003 TRANSMISSION STARTED TO GO AND WAS TOLD BY DUTTON MOTORS IN RIVERSIDE THAT GMPP WAS NOT GOING TO PAY THE CLAIM BECAUSE WE MISSINSTALLED A TRANSMISSION FILTER. APPROVED DUTTON TO FIX CAR AND FIND OUT THEY NEVER PUT IN A CLAIM TO GMPP. CALLED DUTTON TO SEE WHY AND THEY ENDED UP HAVING GMPP ADJUSTER OUT WHEN TRUCK WAS ALREADY FIXED. GMPP DENIED CLAIMING WRONG FILTER INSTALLED. WE WERE TOLD BY DUTTON FILTER WAS INSTALLED WRONG. TWO DIFFERENT STORIES. WE PAID TO HAVE TRUCK FIXED BUT COMPLAINED ON CUSTOMER SATISFACTION CARD. NEVER HEARD FROM GM AGAIN. JULY 2003 EXACTLY TWO MONTHS AFTER LAST REBUILD. MY KIDS AND I WERE IN CARPOOL LANE GOING 70MPH WHEN TRANNY SOUNDS LIKE IT SUCKED UP A THOUSAND COINS. ALMOST IN CAR WRECK WHEN I PULL OVER AND GET OFF FREEWAY. TOW TRUCK TAKES TO DUTTON BECAUSE THEY DID ORIGINAL WORK. TOOK TWO WEEKS TO DIAGNOSE PROBLEM AND TOLD IT WAS SOMETHING COMPLETELY DIFFERENT THAN LAST REBUILD AND THAT GMPP WOULD BE PAYING FOR IT. ADJUSTER AGAIN CAME OUT & DENIED CLAIM. THEY SAY THAT SOMEONE HAD TO HAVE SHIFTED INTO PARK WHILE TRUCK STILL MOVING. DUTTON CLAIMS THAT GMPP NEVER DENIES CLAIMS BUT THEY HAVE DENIED ME TWICE. I HAVE LOST TIME FROM WORK. $5000 FOR REPAIRS AND RENTAL CAR, STRESS, ETC... WHEN WARRANTY WAS SOLD TO US IT DID NOT MENTION ANYTHING ABOUT NOT COVERING THESE TYPE OF THINGS. I HAVE ORIGINAL EVERYTHING FROM PAMPHLET TO ALL INVOICES OF REPAIRS. I CAN NOT AFFORD THESE REPAIRS AND NEED HELP!!!! THERE IS SO MUCH MORE TO THIS STORY.

Vehicle Wide Programming (VWP) is a new process to update software on GM Vehicles. It provides the ability via a single selection within Techline Connect to first identify which modules need updating and then proceed to updating affected modules (with some exceptions). The updating of modules is completed in parallel instead of the technician needing to update one module at a time. This allows a more streamlined approach for dealers and customers.

GM is receiving damaged (cracked or broken) transmission cores returned to the reman facilities. The damage is being caused either in the removal process by the technician, or inadequate packaging or shipping. This bulletin advises the dealers to be more careful not to damage the transmissions during removal and to package the core properly for return.

This service bulletin advises of a new fuel injection cleaner kit used for decarbonizing the intake valves to correct conditions of rough idle, Crank no start, extended crank or misfire, MIL with DTCs, and explains how Top Tier fuels should be used to reduce carbon build-up.

This bulletin provides information for use on a Product Assistance Claim (PAC), which is formerly known as a Product Allegation Resolution (PAR) claim.

This service bulletin provides service information to technicians on guidelines to replace Oil Cooler, Oil Cooler Lines and Oil Tank if the engine was replaced where large amounts of debris has flowed throughout the oiling system.
