MY FUEL GAUGE IS NOT ACCURATE. WHEN THE VEHICLE IS FULL THE GAUGE READS EMPTY AND WHEN IT IS THE VEHICLE IS EMPTY THE FUEL GAUGE READS FULL AND SO ON. THE GAUGE IS VERY SPORADIC POINTING TO WHATEVER LEVEL OF FUEL IT WANTS TO, NEVER DISPLAYING THE TRUE AMOUNT OF FUEL IN THE FUEL TANK. I HAVE TO DEPEND ON MY ODOMETER TO READ THE FUEL TANK AMOUNT SOMEWHAT ACCURATELY; AT LEAST MUCH MORE ACCURATE THAN THE FUEL GAUGE WHICH IS TOTALLY INACCURATE ALL THE TIME. THIS IS A BIG PROBLEM AND FROM THE INFORMATION I HAVE RECEIVED, NOT AT ALL AN ISOLATED ONE. IT SEEMS THAT EVERY '99 CHEVY SILVERADO HAS THE SAME ISSUE. *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.
