BRAKE LINE BLEW OUT DUE TO CORROSION WHEN PULLING TO A STOP LIGHT, WAS ABLE TO STOP THE TRUCK W/O INCIDENT. THIS WAS 8AUG09. REPAIRED ON 12AUG09. ON 5AUG11 WENT TO REPLACE SHOCKS THINKING THEY WERE SHOT, PROBLEM DISCOVERED, ENTIRE SHOCK MOUNT RAIL ASSEMBLY HAD RUSTED AWAY FROM THE FRAME AND IS HANGING IN THE AIR. MILEAGE: 148876. ON 30SEP11 GAS TANK DROPPED TO THE GROUND DUE TO CORROSION OF FRAME, AND ALSO EXHAUST SYSTEM COMPONENTS HAVE ROTTED AWAY FROM THE FRAME AND NOW HANGING, THERE ARE ALSO SOME CRACKS IN THE FRAME, MILEAGE 149476. THERE IS NO RUST OR DAMAGE TO THE BODY ON THIS TRUCK AT ALL. IT STILL LOOKS LIKE A NEW TRUCK. THE FRAME IS ROTTING AWAY FROM UNDER THE TRUCK. I SHOULD HAVE BOUGHT A FORD. WILL NEVER BUY ANOTHER CHEVY. FROM WHAT I SEE, THIS IS A KNOWN PROBLEM THAT GM KNOWS ALL ABOUT AND REFUSES TO DO ANYTHING ABOUT ALL THESE TRUCKS. GM SHOULD RECALL AND REPLACE EVERYONE'S FRAMES ON TRUCKS LIKE MINE THAT HAVE PERFECT BODIES BEFORE SOMEONE GETS KILLED. *TR

BEFORE HE COULD DETERMINE WHAT HAD FALLEN OFF THE VEHICLE, THERE WAS A HOLE WORN IN THE TANK DUE TO BEING DRAGGED ON THE ASPHALT. IT SPILLED A FULL TANK OF GAS ON THE HIGHWAY. THE TRUCK HAD TO BE TOWED ON A FLATBED TRUCK. WE HAD TO REPLACE THE GAS TANK STRAPS, FUEL PUMP AND GAS TANK. THERE WERE NO INJURIES BUT THE FIRE DEPT. AND POLICE HAD TO BE CALLED AS A PRECAUTIONARY MEASURE BEFORE WE COULD LOAD IT ONTO THE FLATBED TOW TRUCK . *TR

SEVERAL YEARS AGO MY FUEL GAUGE BEGAN ACTING UP. IT WOULD FLIP QUICKLY TO THE "NO GAS" POSITION PERIODICALLY AND THEN FLIP BACK SEVERAL MINUTES LATER. THE LOW FUEL LIGHT WOULD GO OFF AND ON. WHEN I FILL THE TRUCK UP IT ALWAYS FLIPS TO THE EMPTY POSITION AND THEN BEGINS IT'S BACK AND FORTH FLIPPING. I HAVE TRAINED EVERYONE IN MY FAMILY TO ALWAYS RESET THE MILEAGE INDICATOR AND WATCH IT CAREFULLY TO INSURE THEY DON'T RUN OUT OF GAS. I'VE HAD NUMEROUS CARS OVER THE YEARS (HONDA FOR 20 YEARS) AND HAVE NEVER EXPERIENCED A PROBLEM LIKE THIS. AT THE PRESENT TIME, TWO PEOPLE I KNOW WITH THE SAME TRUCK BUILT THE SAME YEAR OR WITHIN A YEAR OF MINE HAVE THE SAME PROBLEM. I'M WONDERING WHY A RECALL HAS NOT BEEN ISSUED FOR THIS PROBLEM. *TR

TL*THE CONTACT OWNS A 1999 CHEVROLET SILVERADO 1500. THE CONTACT PLACED BAD GASOLINE IN HIS VEHICLE ONCE AND HAD TO REPLACE THE FUEL TANK. WHILE REMOVING THE TANK, HE NOTICED THAT THE FRAME WAS CORRODED AND HAD SPREAD TO THE REAR BUMPER. THE AUTO GARAGE STATED THAT THE FRAME NEEDED TO BE REBUILT. THE REPAIR COST WOULD EXCEED $1,500; THEREFORE, THE CONTACT IS UNABLE TO HAVE THE VEHICLE REPAIRED AT THIS TIME. THE MANUFACTURER FILED A REPORT AND SENT AN INVESTIGATOR TO INSPECT THE FRAME, AND CONCLUDED THAT THEY WERE NOT GOING TO ASSIST WITH THE REPAIR BECAUSE THE VEHICLE IS OVER EIGHT YEARS OLD. THE CURRENT AND FAILURE MILEAGES WERE 145,000.

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.
