HAD TO DISCONNECT THE ANTI LOCK BRAKE SO I COULD STOP. WHEN DRIVING SLOW AND PRESSING ON THE BRAKE PEDAL, THE PEDAL IS SOLID AND DOES NOT MOVE. VERY DANGEROUS. CANNOT STOP THE VEHICLE AT ALL. BRAKE LINES ROTTED OUT. HAS TO REPLACE. TRANSMISSION LINES ROTTED OUT. HAD TO REPLACE. TRANSMISSION OIL COOLER ROTTED OUT. HAD TO REPLACE. FUEL LINES ARE ROTTING OUT. NOT REPLACED YET. DRIVE SHAFT IS QUESTIONABLE. SEVERELY RUSTED. REAR BACKING PLATES ROTTED OFF, NO MORE PARKING - EMERGENCY BRAKE. CHECK ENGINE LIGHT WILL NOT GO OUT. REPLACED CATALYTIC CONVERTER MANY TIMES WITH NO RESULTS. ENGINE LEAKS OIL. LOOSING COOLANT, POSSIBLE BURNING IT. FUEL MILEAGE IS TERRIBLE. BODY RUSTED OUT. ROCKER PANELS ARE GONE. CAB CORNERS ARE GONE. REAR BUMPER IS GONE. PUTTING THE SPARE TIRE UNDERNEATH IS A STUPID IDEA. THE COST TO REPLACE THESE PARTS IS TOO EXPENSIVE. FOR WHAT THESE VEHICLES COST NEW ALL OF THESE PARTS SHOULD BE MADE OUT OF STAINLESS STEEL OR USE PLASTIC FOR THE FUEL LINES AND BRAKE LINES. THE CHECK ENGINE LIGHT BEING RELATED TO A POLLUTION CONTROL DEVICE SHOULD BE ENTIRE COVERED BY THE MANUFACTURER. THESE PARTS AND WHATEVER IS UPSTREAM THAT CAUSED THE POLLUTION CONTROL PART TO FAIL SHOULD BE COVERED BY THE MANUFACTURER IN PERPETUITY. ANTI LOCK BRAKES SHOULD BE REMOVED FROM ALL CARS. THE PARTS ARE TOO EXPENSIVE TO REPLACE. THE COST SHOULD NOT BE ON THE SHOULDERS OF THE CAR OWNER. *TR

THE FUEL LINE SUPPLYING THE ENGINE FUEL RAIL RUPTURED DUE TO EXCESSIVE CORROSION BECAUSE OF THE LOCATION IT IS IN AND FUEL WAS SPRAYING OUT UNDERNEATH THE TRUCK,. DANGEROUSLY CLOSE TO THE HOT CATALYTIC CONVERTER. THE DEFECTIVE FUEL LINE IS AN EXTREMELY DIFFICULT REPAIR, DUE TO HAVING TO REMOVE THE BED/CAB FOR REPLACEMENT AND ACCESS TO IT. THE FUEL AND BRAKE LINES ARE IMPROPERLY ROUTED FROM THE FACTORY, CAUSING PREMATURE FAILURE DUE TO CORROSION AND SALT DAMAGE. IN MY OPINION, THERE SHOULD BE A RECALL AND THIS INHERENTLY DANGEROUS PROBLEM RECTIFIED. THE BRAKE LINES ON THIS SAME TRUCK FAILED FROM CORROSION TWO YEARS AGO. SAME SCENARIO, IMPROPER ROUTING CAUSING EXCESSIVE AND PREMATURE FAILURE FROM RUST AND CORROSION DUE TO THE LOCATION THEY ARE IN. *TR

BRAKE LINE FAILURE ON 2000 CHEVY SILVERADO 1500. HAS HAPPENED TWICE DUE TO LINES RUSTING OUT, AND NOW MECHANIC SAYS FUEL LINES ARE RUSTING OUT. I LIVE IN KY WITH LITTLE SALT AND HAVE HEARD NUMEROUS OTHER COMPLAINTS ABOUT THE SAME ISSUE. DRIVING ALONG AND BAM, NO BRAKES DUE TO CORROSION. LAST TIME IT HAPPENED TO MY WIFE AND PREGNANT DAUGHTER IN LAW. SOMEONE IS GOING TO GET SERIOUSLY HURT OR KILLED IF IT HASN'T ALREADY HAPPENED. GM HAS OUR TAX DOLLARS AND SHOULD USE SOME OF IT TO RECALL AND FIX THIS DEADLY PROBLEM. THIS IS COSTING BETWEEN $400.00 TO $600.00 TO REPAIR. LOCAL MECHANIC HAS SAID IT IS A CONSTANT PROBLEM WITH THESE VEHICLES IN THIS YEAR RANGE, ALONG WITH TAHOES. *TR

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.
