I was driving today and my truck started making a strange noise(like something was loose). I stop the truck to see what was loose, I found nothing. I got back in the truck driving about 20 mph the truck started making the noise again and the truck started dragging( like it wouldn't go faster). I then stop and pulled in a church parking lot where the truck was not drivable. I was told by a concern passerby( mechanic, which happen to be) it's has something to do with the rest axle. The truck gave me no warning whatever. I was told I could have had a major accident and I had NO!!! warning. Please, fix. I have nothing but, issues with this truck.

TL* THE CONTACT OWNS A 2002 CHEVROLET SILVERADO 1500. WHILE DRIVING APPROXIMATELY 60 MPH, THE TRANSMISSION FAILED TO RESPOND PROPERLY IN THE OVERDRIVE POSITION. IN ADDITION, THE TRANSMISSION TEMPERATURE WARNING INDICATOR ILLUMINATED. THE FAILURE RECURRED WHENEVER THE VEHICLE WAS IN OPERATION. THE VEHICLE WAS TAKEN TO AN INDEPENDENT MECHANIC ON THREE SEPARATE OCCASIONS WHERE A REPAIR WAS PERFORMED EACH TIME. THE CONTACT WAS UNCERTAIN OF THE SPECIFIC PARTS THAT WERE REPLACED. THE FAILURE RECURRED AND AN INDEPENDENT MECHANIC WAS DIAGNOSING THE VEHICLE. THE MANUFACTURER WAS NOT NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE AND VIN WERE UNAVAILABLE.

CRESTED A SMALL HILL TO SEE A RED LIGHT WITH THREE CARS IN LINE. I DEPRESSED BRAKE PEDAL, WHICH WENT TO THE FLOOR. THE VEHICLE WAS STOPPED USING THE PARKING BRAKE AFTER SWERVING INTO EMPTY LANE OF ONCOMING TRAFFIC IN ORDER TO AVOID HITTING THE LINE OF CARS FROM BEHIND. UPON INSPECTION, THE FRONT BRAKE CIRCUIT WAS BLOWN IN THE PIPING JUST AFT OF THE FRONT DRIVER'S SIDE WHEEL. IT IS EXTREMELY DIFFICULT TO STOP A LARGE TRUCK WITH EMPTY BED USING ONLY THE REAR BRAKES AS THEY LOCK UP EASILY. THERE SEEMED TO BE NO BRAKE POWER USING THE BRAKE PEDAL, WHICH IS WHY THE PARKING PEDAL WAS USED. EVEN WITH A FUNCTIONAL PARKING BRAKE, THE "FAILSAFE" OF HAVING ONLY ONE CIRCUIT IS NEARLY USELESS GIVEN AN EMPTY TRUCK BED (LOW REAR-WHEEL TRACTION) AND A LOSS OF PRESSURE ON THE FRONT CIRCUIT. IN MY OPINION, LOSING THE FRONT BRAKES ON A TRUCK IS CATASTROPHIC. IN ANY EVENT, IN MY CASE, THE SUPPOSED FAIL-SAFE EITHER DID NOT WORK OR WAS INCONSEQUENTIAL. ALL OF THE HARD LINES (FUEL AND BRAKE) ON THIS VEHICLE ARE EXTREMELY CORRODED AND ARE BEING REPLACED WITH STAINLESS. THIS CAR SPENT THE FIRST FIVE YEARS OF ITS LIFE IN OKLAHOMA AND MISSOURI (WHERE LITTLE TO NO SALT IS USED) AND MOVED TO NH IN 2006. THE REAR DRIVER'S SIDE ROCKER PANEL IS ALSO RUSTED THROUGH AND THE FRAME HAS VERY SIGNIFICANT RUST, ESPECIALLY ON THE LEAF SPRING HANGERS. IN ADDITION, THE FRONT DRIVESHAFT IS RUSTED TO THE POINT THAT I WILL NOT OPERATE THE VEHICLE IN 4WD UNTIL I REPLACE IT. THIS VEHICLE SEEMS VERY SUSCEPTIBLE TO RUST, ESPECIALLY THE BRAKE LINES, SOME OF WHICH CRUMBLED IN MY HUSBANDS HANDS WHILE REMOVING. *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.
