2003 GMC C/K 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.

TODAY, A FIRESTONE DESTINATION LE FRONT DRIVERS SIDE TIRE EITHER BLEW APART OR RAN OVER SOMETHING SO DEVASTATING CAUSING IT TO BLOW OUT ON MY 2003 GMC SIERRA 4WD EXT CAB TRUCK. THIS CAUSED THE TRUCK TO SKID ACROSS THE OPPOSITE LANE OF TRAFFIC WHILE TURNING AND TWISTING ON WHAT FELT LIKE TWO WHEELS INTO A STEEP DITCH, NEARLY CAUSING A COMPLETE ROLL-OVER. DRIVING CONDITIONS WERE 30 TO 40 MPH ON A MODERATELY CURVY COUNTRY ROAD IN 20 DEGREE WEATHER WHILE IN 2 WHEEL DRIVE. ADDITIONAL DETAILS ARE: TIRES ARE LESS THAN 1 YEAR OLD, LESS THAN 8000 MILES ON THEM. EVEN IF I HAD RUN-OVER A SHARP OBJECT CAUSING THE TIRE TO GO FLAT, IT SHOULD NOT HAVE DISTENGRATED OR 'BLOWN-APART' IN SECONDS NEARLY CAUSING A POSSIBLE FATAL ACCIDENT. CAN ANYONE STEER ME IN THE NEXT DIRECTION FOR MORE INFO ON THIS TIRE WITH SIMILAR RESULTS? YOUR ASSISTANCE IS MUCH APPRECIATED. *TR

INTERMEDIATE STEERING SHAFT. SAME PROBLEM AS WE HAD REPAIRED ON OUR 1999 GMC 3/4 TON. THE 2003 HAS EXACTLY THE SAME PROBLEM. MY SON'S 2001 TAHOE HAS THE SAME IDENTICAL PROBLEM WITH HIS. FLYER ON ALL OF THESE VEHICLES ON INTERMEDIATE STEERING SHAFT. 1999 HAS HAD THE SHAFT REPLACED 6 TIMES. TAHOE HAS HAD SHAFT REPLACED 2 TIMES. 2003 HAS SAME PROBLEM AND THEY GREASED IT BECAUSE THEY SAY IT CAME FROM FACTORY WITH NO GREASE!!!! LOOKS AS IF THIS IS A REAL PROBLEM BROTHER-IN-LAW WORKS FOR GM AND SAYS THE 2004 SHOULD BE FIXED, HA,HA.
