2001 CHEVY SILVERADO LOW FUEL LIGHT NOT WORKING. LOW FUEL LIGHT STAYS ON EVEN WHEN TANK IS FULL. FUEL NEEDLE MOVES CONSTANTLY FROM FULL TO EMPTY, REGARDLESS OF AMOUNT OF GAS IN TANK. RAN OUT OF GAS TWICE DUE TO THIS PROBLEM. HOW IS THIS NOT A RECALL? *TR

FUEL GAUGE DOES NOT WORK PROPERLY, IT SHOWS RANDOM FUEL AMOUNTS. IT HAS LEFT ME OUT OF GAS SEVERAL TIMES. ALL MY FAMILY DRIVES SILVERADOS AND GMC SIERRA, AND ALL HAVE THE SAME PROBLEM. THIS IS VERY DANGEROUS, WHAT IF I RUN OUT OF FUEL ON THE HIGH AND MY TRUCK STALLS AND CAUSES AN ACCIDENT. *TR

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 AND FUEL GAGE. I RECENTLY MOVED OVERSEAS WITH AF AND HAD TO HAVE MY VEHICLE INSPECTED FOR EUROPEAN STANDARDS. MY PARKING BREAK DID NOT WORK AT ALL. I FOUND THIS HARD TO BELIEVE SINCE I HAVE NEVER USED IT. I WAS MANDATED BY EUROPEAN LAW TO GET FIXED IN ORDER TO DRIVE IT AND PAY A $30 FOR EACH MONTH UNTIL I GOT IT FIXED. MY FUEL GAGE DOESN'T MAINTAIN HOW MUCH FUEL I HAVE IN MY GAS TANK. WHEN I HAVE A FULL OR EMPTY TANK THE GAUGE JUST RANDOMLY BOUCESS AROUND WITH THE UNKNOWN CORRECT AMOUNT. I AM CURRENTLY SETTING THE MILEAGE UNTIL I CAN FIND SOMEONE TO FIX IT AND THE PARTS I NEED. *TR

FAILURE OF FUEL PUMP IN MY 2001 5.3 LITER CHEVROLET SILVERADO TO ACCURATELY DETERMINE AMOUNT OF FUEL IN TANK. WHEN I FILL MY TANK WITH FUEL THE GAUGE READS ERRATICALLY, THE NEEDLE PINS ITSELF IN THE EMPTY POSITION. THE PROBLEM IS CONSTANT AND ON GOING. I NOTIFIED GM AND THEY OFFER NO REPAIR YET THIS SAME PROBLEM QUALIFIED AS A RECALL FOR REPAIR ON THE 2001 MODEL SUBURBAN WITH THE 5.3 LITER ENGINE. SIMPLY DO A GOOGLE SEARCH FOR 2001 SIVLERADO FUEL GAUGE PROBLEMS AND YOU WILL BE AMAZED AT THE NUMBER OF RESPONDENTS WHO HAVE THE IDENTICAL PROBLEM YET THERE IS NO ACCOUNTABILITY FROM GM. THANK YOU *TR

GAS GAUGE BOUNCES FROM FULL TO EMPTY AND READS INACCURATE AT TIMES EVEN AFTER FILLING TANK. WITH A FULL TANK GAUGE WILL BOTTOM OUT AT EMPTY AND INITIATE LOW FUEL LIGHT AND THEN RETURN BACK TO FULL. *JB

THE FUEL GAGE DOES NOT READ ACCURATELY. WHEN THE FUEL TANK IS FULL, THE GAGE READS EMPTY. AFTER SOME FUEL IS USED IT SEEMS TO READ PROPERLY UNTIL AROUND HALF A TANK, AT WHICH POINT IT STARTS TO BOUNCE AROUD BETWEEN EMPTY AND THE PROPER READING. IT WILL ALSO READ EMPTY IF THE TRUCK IS PARK AND IDLING FOR A SHORT PERIOD OF TIME

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.
