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.

VEHICLE WAS RECALLED FOR ANTI-LOCK BRAKE DEFECT AND REPAIRED AT LOCAL DEALER ON 1/19/06. STARING ABOUT 1/1/09 THE SAME PROBLEM STARTED HAPPENING AGAIN. ANTI-LOCK WOULD ACTIVATE DURING NORMAL STOP ON DRY PAVEMENT. THIS HAPPENS ON EVERY STOP AND ACTIVATES AROUND 5 MPH. I CALLED THE DEALER AND THEY ADVISED ME THAT THEY FIXED IT ONCE AND ARE NOT REQUIRED TO FIX IT AGAIN. I TOOK IT TO AN INDEPENDENT SHOP AND THEY MADE THE SAME REPAIR THAT WAS MADE WITH THE RECALL. *TR

I CALLED MICHAEL GMC, 3700 S CARSON, CARSON CITY NV TO HAVE A STICKY ACCELERATOR PEDAL ON MY 1999 GMC SIERRA PU REPAIRED. I STATED I KNEW OF A TSB ISSUED FOR THIS DEFECT. I WAS TOLD THERE WAS NO TSB. I CHECKED VIA THE INTERNET AND FOUND TSB #00-06-04-007A HAD BEEN ISSUED IN JUN 00. I HAVE FOUND A GM DEALER WHO WILL REPAIR THIS FOR ME. BUT I THINK THAT HOHL SHOULD NOT HAVE REFUSED TO CORRECT THIS PROBLEM UNDER THE TSB. DO I HAVE ANY RECOURS TO HOHL FOR MISLEADING ME?*AK

WE OWN THREE 1999 GMC 1500 C PICKUPS. EACH OF THESE VEHICLES HAS EXPERIENCED THE FAILURE OF THE UNDER DASH ABS ELECTRONIC MODULES WHEN THE VEHICLES REACHED APPROXIMATELY 85,000 MILES OR SO. WE CONTACTED GMC TO PLACE A COMPLIANT. THE REPAIR CHARGES FOR THIS PROBLEM HAVE RANGED FROM $800 TO $1050 EACH. GMC REFUSES TO ACKNOWLEDGE THE PROBLEM OR TO REIMBURSE FOR ANY REPAIR COSTS FOR THEIR OBVIOUS DEFECTIVE PARTS. FAILURE OF THE ABS MODULE STILL ALLOWS FOR USE OF THE BRAKES BUT FAILURE OF THE ABS SYSTEM WHICH COULD RESULT IN ACCIDENTS. *JB
