2001 GMC C/K Pickup

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.

SUBJECT POWER WINDOW MOTOR/REGULATOR FAILURE DUE TO COLD WEATHER CONDITIONS. NO WARRANTY RECALL ASSISTANCE FROM GMC/CHEVY, BASIC WARRANTY COVERAGE, AFTERWARDS YOU ARE ON YOUR OWN. EXPENSIVE RECURRING PROBLEM IN COLD WEATHER CONDITIONS. YOU LIVE WITH THE FACT THAT IN COLD WEATHER THE WINDOWS MUST STAY UP. IF SOME ONE HAPPENS TO BE WITH YOU AND YOU DON'T LET THEM KNOW QUICK ENOUGH OR THEY FORGET THE CHANCES ARE GOOD THAT YOU WILL BE IN FOR AN EXPENSIVE REPAIR. YOUR WIFE TAKE THE TRUCK LIKE TODAY, YOUR 16 YEAR OLD DECIDES TO CRACK THE WINDOW A LITTLE AND BOOM I AM NOT A HAPPY CAMPER THIS SUNDAY. POWER WINDOW CABLE, MOTOR, REGULATOR BRACKET UNIT ONE PIECE REPLACEMENT IS A POOR LIGHT WEIGHT CABLE DESIGN. I HAVE A 2001 GMC SIERRA Z71 4X4 EXTENDED CAB, A FRIEND HAS THE SAME TRUCK PLUS RECENTLY PURCHASED A NEW ONE MAXED OUT WITH EVERY THING, ANOTHER FRIEND HAS A 2005 K1500 HD WE ALL HAVE EXPERIENCED THE SAME PROBLEMS. THE 2005 CAME INTO MY SHOP FOR LUBE SERVICE RECENTLY ONE COLD NEW YORK MORNING TO HAVE THE DRIVERS SIDE WINDOW REGULATOR UNIT FAIL AND RETURN TO THE DEALER TO WARRANTY THE ITEM AND WHEN THE TRUCK WAS MOVED OUT TO BE PICKED UP IN THE PARKING LOT, THE TECHNICIAN CLOSED THE DRIVER'S SIDE DOOR JUST TO HAVE THE PASSENGER SIDE WINDOW FALL DOWN INTO THE DOOR WITH THE SAME PROBLEM. I PURCHASED THE 2001 WITH 39,000 MILES FROM A GM DEALER APPROXIMATELY. 3 YEARS AGO AND HAVE EXPERIENCED WINDOW PROBLEMS IN COLD WEATHER CONSTANTLY AS OTHERS I KNOW WITH THE SAME TYPE OF TRUCKS. THIS PROBLEM NEEDS TO BE ADDRESSED AND CORRECTED PROMPTLY. I PERSONALLY WOULD NOT BY ANOTHER BRAND TRUCK AND CHEVY/GMC TRUCK HAVE BEEN MY GRANDFATHERS CHOICE AS WELL AS MY OWN. *NM

THE LAST FEW MONTHS I HAD NOTICED I HAD TO APPLY A LOT MORE FOOT PRESSURE TO STOP MY 2001 GMC. AN INSPECTION SHOWED THAT AT 48,000 MILES THE REAR INSIDE BRAKE PADS WERE COMPLETELY GONE AND BOTH ROTORS WERE LIKE CORNFLAKES. I HAD NOT HEARD ANY INDICATION FROM THE CHIRPERS THAT I HAD UNUSUAL WEAR. I HAVE DRIVEN ALL MY GM TRUCKS AT LEAST 90,000 MILES AND NEVER HAD TO REPLACE THE REAR BRAKES. I NOW AM AWARE THAT THIS IS A COMMON OCCURANCE AT AS LOW AS 30,000 MILES. SOMEONE SHOULD BE NOTIFYING OWNERS OF VEHICLES WITH THIS PROBLEM VIA A RECALL OR MAIL, THAT THIS NEW DISC BRAKE ON THE REAR OF GM TRUCKS DOESN'T LAST LIKE THE DRUM BRAKES DID, AND BE PREPARED TO SHELL OUT $800.00 TO REPAIR THEIR FAULTY ENGINEERING.*AK
