2002 GMC SIERRA 1500 P/U W/4.3 LT. V-6, I HAVE HAD TO HAVE THE A/C CONDENSATION LINE COVERED THREE TIMES WITH THE FOAM INSULATION FROM MY DEALER. THEY ALSO HAVE TO CLEAN THE CORROSION FROM THE DISTRIBUTOR, REMOVE THE SCREEN IN THE BOTTOM OF THE DISTRIBUTOR, CLEAN THE SPARK PLUGS AND REPLACE THE CAP AND ROTOR ON EACH OCCASION. MY TRUCK IS CURRENTLY IN THE SHOP AGAIN TO HAVE THE DISTRIBUTOR REPLACED. THIS IS AT A COST OF AROUND $680.00 TO REPLACE THE DISTRIBUTOR , NEW PLUGS DUE TO FOULING AND WIRES. I HAVE SPOKEN WITH GENERAL MOTORS AND TO THE DEALER SEVERAL TIMES REGARDING THE TEMPORARY FIX (BAND-AID). THE AIR CONDITION CONDENSATION LINE IS LOCATED DIRECTLY ABOVE THE DISTRIBUTOR AND THEY REFUSE TO MOVE IT. IT HAS BECOME INCREASINGLY APPARENT THEIR REPAIR IS NOT A FIX BUT A TEMPORARY SOLUTION TO GET YOU OUT OF WARRANTY. THERE HAS BEEN A RECALL SENT TO ME BUT DOES NOT SHOW IN YOUR LISTINGS FOR THE SUBJECT VEHICLE. THIS PROBLEM IS VERY DANGEROUS, YOUR VEHICLE USUALLY GIVES NO SIGNS BEFORE LEAVING YOU STRANDED IN THE MIDDLE OF THE HIGHWAY. MY QUESTION IS WHY THE DEALER GETS AWAY WITH A TEMPORARY FIX AND NOT A RESOLUTION TO THE PROBLEM ? I BELIEVE THE AIR CONDITION CONDENSER LINE SHOULD BE RELOCATED AWAY FROM THE DISTRIBUTOR ALTOGETHER. GMC IS WELL AWARE OF THIS PROBLEM AND RECTIFIED THE RE-ENGINEERING OF THE A/C LINE ROUTE IN THE 2003 MODELS. *NM

THE 2002 WAS IN NEED OF FRONT HUBS SINCE THEY WERE NOT REPLACED WHEN THEY SHOULD HAVE BEEN AT THE TIME THE FRONT DIFFERENTIAL WAS REBUILT. THIS CAUSED THE TRUCK TO HAVE EXCESSIVE FRONT WHEEL FRICTION, AND COMPROMISED THE BRAKING CHARACTERISTICS OF THE TRUCK. IT WAS DIFFICULT TO DRIVE, ESPECIALLY IN SNOW, AND THE FRONT WHEEL FRICTION WOULD VARY BASED ON CHANGES IN SPEED, ROAD CONTOUR, TEMPERATURE, STEERING INPUT, THROTTLE INPUT, AND BRAKE INPUT. WHILE BRAKING THE TRUCK WOULD OFTEN PITCH SEVERELY TO ONE SIDE OR THE OTHER, THE ABS WOULD ACTIVATE ON DRY PAVEMENT. ON ONE OCCASION THE ABS ACTIVATED WHEN MY FOOT WAS OFF THE BRAKE. THE TRUCK WOULD ALSO SWAY FROM SIDE TO SIDE AT HIGHWAY SPEED AS THE FRICTION VARIED FROM SIDE TO SIDE. WHEN THE TRUCK WAS RETURNED TO ME ONCE FROM CULLIGAN GMC, THE POWER STEERING EFFORT HAD INCREASED GREATLY. THE CHARACTERISTICS OF THE REAR LOCKING DIFFERENTIAL HAD BEEN CHANGED. THE TRUCK WAS BACK TO THE DEALER, DAVID CADILLAC, MANY TIMES FOR THE SAME CONCERN WITH THE FRONT DIFFERENTIAL. ON ONE OCCASION THE TRUCK WAS RETURNED TO ME GUSHING GEAR LUBE FROM THE FRONT AXLE, ON ANOTHER IT WAS RETURNED TO ME WITH THE FRONT DIFFERENTIAL EMPTY. I WAS CHARGED FOR A 4 WHEEL ALIGNMENT WHEN ONLY 2 WHEELS CAN BE ALIGNED ON THIS TRUCK. THE WRONG OIL FILTER WAS INSTALLED, THE TRUCK WAS DRIVEN ABUSIVELY BY A DEALER EMPLOYEE (IT WAS RUN BEYOND MECHANICAL LIMITS WHILE COLD AS I STOOD IN THE PARKING LOT), AND WHEN I CALLED THE SERVICE ADVISER AFTER THE TRUCK HAD BEEN IN HIS SHOP FOR OVER A WEEK WITHOUT MY HEARING WHAT IT'S STATUS WAS, THE SERVICE PERSON SCREAMED AT ME ON THE PHONE "WHEN IT IS FINISHED I WILL CALL YOU!!!", AND HE SLAMMED THE PHONE DOWN. *NM

I BOUGHT TWO CABLES FROM ADVANCE AUTO REPLACED ONE SIDE BUT I COULD NOT GET THE BOLT BACK IN THE OTHER SIDE. I WAS PLANNING TO TAKE THE TRUCK TO THE DEALER THE FOLLOWING WEEKEND FOR THE RECALL BUT THE GATE FELL OFF THE TRUCK AND I DID NOT KNOW IT HAD FELL OFF AND I DRAGGED IT DOWN A DIRT ROAD FOR ABOUT HALF MILE OR MORE. I TRIED TO GET GMC TO REPLACE THE TAIL GATE BUT THEY JUST WANTED TO REPLACE THE CABLE SAYING THAT THE CABLE DID NOT CAUSE THE TAIL GATE TO FALL OFF AND THE DAMAGE WAS NOT DUE TO THE CABLES. I FEEL THAT THE CABLE PROBLEM CAUSED THE TAIL GATE TO FALL OFF. *JB

ON DEC 8, 2003 I WAS DRIVING AT APPROX. 45 MILES PER HOUR WHEN MY TRANSMISSION SHIFTED OUT OF GEAR AND THEN AFTER A FEW SECOUNDS IT SHIFTED INTO LOW GEAR, ALL ON ITS OWN. THERE WAS A CAR TRAVELING BEHIND THAT ALMOST HIT ME FROM BEHIND. I PULLED OVER AND PUT MY TRUCK IN PARK. I LOOKED UNDER MY TRUCK TO SEE IF ANY THING HAD COME APART. I DID NOT SEE ANY FLUID LEAK OR ANY LOOSE PARTS. I DROVE MY TRUCK TO THE DEALERSHIP IN LOW GEAR. THEY TOOK MY TRUCK IN FOR REPAIRS (38,127 MILES). I WAS 2,127 MILES OUT OF WARRANTY. THE TRANSMISSION WAS REPAIRED AND IT COST $1,057.19. TODAY 3/30/05 ON MY WAY HOME FROM WORK THE TRANSMISSION DOES THE SAME THING. I ONLY HAVE LOW GEAR AND NO REVERSE. THIS TIME I WAS LUCKY THAT NO ONE WAS BEHIND ME WHEN IT HAPPENED. *AK

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.
