THE FUEL SENDING UNIT IN MY TRUCK FAILED AT ~ 41K MILES AND SENDS FAULTY SIGNALS TO THE GAUGE IN THE INSTRUMENT CLUSTER. THE LEVEL INDICATED ON THE GAUGE FLUCTUATES BUT USUALLY READS EMPTY WHICH LEADS TO A VERY BRIGHT YELLOW "LOW FUEL" INDICATOR IN MY MESSAGE CENTER. I KNOW OF AT LEAST 4 OTHER INDIVIDUALS WHO OWN THE SAME MAKE/MODEL FROM 1999-2001 THAT HAVE THE SAME PROBLEM. THIS IS A SAFETY ISSUE BECAUSE 1) I NEVER KNOW HOW MUCH FUEL IS REALLY IN MY TRUCKS GAS TANK AND COULD BE LEFT STRANDED ON THE SIDE OF ANY HIGHWAY AT ANY TIME, AND 2) THE BRIGHT YELLOW "LOW FUEL" INDICATOR IN THE MESSAGE CENTER THAT STAYS ON NEARLY CONSTANTLY IS EXTREMELY DISTRACTING WHILE DRIVING AT NIGHT. MY ACQUAINTANCES AND I HAVE ALL NOTIFIED THE CHEVROLET DEALER OF OUR PROBLEM AND HAVE BEEN TOLD "CHEVY KNOWS ABOUT THE PROBLEM BUT WILL NOT ISSUE A RECALL" (PARAPHRASING). *TR

PARKING BRAKE FAILURE - DESIGN FAULT. PER CHEVROLET DEALERSHIP AND INDEPENDENT MECHANIC THE PARKING BRAKE FAILURE TO ENGAGE IS DUE TO NOT USING THE PARKING BRAKE EACH TIME THE TRUCK IS PARKED. THIS IS A DESIGN FAULT AS A PART SHOULD NOT FAIL IF YOU USE IT ONLY AS NEEDED. CHEVROLET HAS A RECALL FOR THE 2001 SILVERADO MANUAL TRANSMISSION BUT HAS NOT RECALLED THE AUTOMATIC TRANSMISSION MODELS WITH THE SAME ISSUE. ABS BRAKES: ABS LIGHT GENERALLY COMES ON WHEN DRIVING THE TRUCK. CHEVROLET HAS A RECALL FOR THE ABS SYSTEM FAILURE ON THE 2001 SILVERADO BUT HAS LIMITED THE RECALL TO STATES WITH MORE EROSION (SALT) AND THEREFORE IS NOT FIXING THIS ISSUE IN TEXAS. ELECTRICAL SYSTEM - INSTRUMENT PANEL: THE INSTRUMENT PANEL DISPLAYS WARNING LIGHTS, E.G. ABS LIGHT, BRAKE LIGHT, ETC. INTERMITTENTLY. CHEVROLET HAS A RECALL ON THE 2001 CHEVROLET SILVERADO INSTRUMENT PANEL HOWEVER NOT FOR THIS VIN NUMBER. *TR

THE STALK FOR THE COMBINATION TURN SIGNAL, WINDSHIELD WIPER, CRUISE CONTROL, BROKE RESULTED IN UNRELIABLE OPERATION OF THE WINDSHIELD WIPERS AND UNRELIABLE TURN SINGAL OPERATION. IN THE CASE OF THE 2001 SILVERADO THE WINDSHIELD WIPERS ACTIVATED WHEN THE TURN SIGNALWAS SELECTED. SINCE THIS SAME CONTROL WAS USED FOR SEVERAL CRITICAL FUNCTIONS, INCLUDING TURN SIGNALS, WIPERS, AND CRUISE CONTROL ACTIVATION AND DEACTIVATION, I EXPECT CERTAIN FAILURE MODES COULD PRESENT A SERIOUS SAFETY ISSUE. RESEARCHING THIS ISSUE, IT SEEMS TO BE A COMMON PROBLEM ON THIS MODEL SILVERADO AND OTHER GM VEHICLES THAT USE THE SAME COMBINATION CONTROL.*AK

FAN WENT OUT, SHORT IN WIRING IN DOOR LOCKS AND WINDOWS, THIS A 2001, 56,000, MILES, LOW MILEAGE TRUCK TO HAVE SO MANY PROBLEMS, THE DEALERSHIP SAID THEY HAD NOT SEEN THIS PROBLEM BEFORE, I LOOKED IT UP, THERE IS RUSTING AND TOTAL CORROSION OF THE BRAKE ROTORS IN MANY DIFFERENT STATES, OVER ALONG PERIOD OF TIME, EVEN WHEN THE ROTORS ARE REPLACED THEY ARE RUSTING COMPLETELY AGAIN. CHEVY IS SELLING AN EXPENSIVE TRUCK, AND THEN PROFITING AGAIN ON THE REPLACEMENT OF THE DEFECTIVE PARTS, AND MAKING A PREMIUM PROFIT ON THAT TOO.! THEY ARE NOT BOTHERING TO FIX A DEFECT THAT HAS BEEN GOING ON FOR A LONG TIME. VERY DISGUSTED WITH THE CHEVY SILVERADO, MY FIRST AND LAST CHEVY. *NM

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.
