FUEL PUMP FAILED ON THE HIGHWAY, CAUSING THE VEHICLE TO STOP WITHOUT WARNING. MILEAGE WAS ONLY 33,100 AT THE TIME. I HAVE SEARCHED A CHEVROLET TRUCK OWNERS WEBSITE (GOOGLE ALT.TRUCKS.CHEVY - ADVANCED SEARCH: FUEL PUMP) AND FOUND MANY REPORTS OF FUEL PUMP AND/OR FUEL PUMP FUSE FAILURE IN 1996-2001 CHEVY TRUCKS. THE TYPICAL FAILURE SEEMS TO BE MELTING OF WIRES INSIDE THE PUMP, CAUSING INTERNAL SHORTING, WHICH WAS THE FAILURE IN MY VEHICLE. FAILURES WERE REPORTED TYPICALLY AT 30,000-75,000 MILES. FAILURE CAN BE INTERMITTANT AND DIFFICULT TO DIAGNOSE. AN ADDITIONAL CAUSE OF FUEL PUMP FUSE BLOWING IS SHORTING OF THE OIL PRESSURE SWITCH, WHICH IS IN THE FUEL PUMP CIRCUIT. REPAIR WAS COVERED UNDER MY GM EXTENDED WARRANTY, BUT WOULD HAVE OTHERWISE COST APPROXIMATELY $700.*AK

THE BATTERY POSITIVE LEAKED ONTO THE BRAKE LINE WHICH IN TURN ATE THROUGH THE BRAKE LINE AND A LOSS OF BRAKE FLUID AND BRAKES WITHOUT WARNING HAPPENED. I WAS TRAVELING AT 40MPH WHEN WENT TO APPLY THE BRAKES AND THEY WENT SLOWLY TO THE FLOOR AS I WAS STOPPING AND THEN DROPPED TO FLOOR AND I WENT THRU THE MIDDLE OF A INTERSECTION (I THANK GOD THAT TRAFFIC WAS LIGHT). I SEE THAT IN THIS DATA BASE THAT THIS IS COMMON PROBLEM AND I CAN'T BELIEVE THAT THIS IS NOT A RECALL. HOW MANY PEOPLE HAVE TO BE HURT OF KILLED BEFORE GMC DOES SOMETHING ABOUT THIS. I HAVE PURCHASED 8 NEW GM VEHICLES IN THE LAST 10 YEARS AND IF THIS IS THE WAY THEY ARE GOING TO TREAT CUSTOMERS, I WILL NOT BUY ANOTHER. NEEDLESS TO SAY THE VEHICLE WILL BE FOR SALE AS SOON AS IT IS FIXED AND ANOTHER BRAND WILL BE CONSIDERED. *AK

THIS INVESTIGATION INVOLVES THE GENERAL MOTORS CORPORATION (GM)THROTTLE BODY (TB) UTILIZED IN MODEL YEAR (MY) 1999-2002 SILVERADO, SIERRA, TAHOE, SUBURBAN, AVALANCHE AND YUKON (SUBJECT VEHICLE(S)) WITH 4.8L, 5.3L, AND 6.0L ENGINES. THE TB VALVE MAY INTERMITTENTLY STICK IN A CLOSED POSITION.IN SUCH A SITUATION, AN OPERATOR MAY APPLY ADDITIONAL ACCELERATOR PEDAL FORCE TO INCREASE ENGINE SPEED.THE APPLICATION OF ADDITIONAL ACCELERATOR PEDAL FORCE, TO OPEN A STUCK THROTTLE VALVE, MAY OPEN THE THROTTLE VALVE MORE THAN INTENDED AND, IN TURN, ACCELERATE THE ENGINE AND VEHICLE MORE THAN INTENDED AND REASONABLY EXPECTED BY THE DRIVER.ON AUGUST 1, 2002, THE OFFICE OF DEFECTS INVESTIGATION (ODI), OF THE NATIONAL HIGHWAY TRAFFIC SAFETY ADMINISTRATION (NHTSA), OPENED THIS ENGINEERING ANALYSIS.THE INVESTIGATION REVEALED THAT TWO FACTORS MAY CAUSE THE DEFECT: 1) TB MANUFACTURING PROCESS PROBLEMS; AND 2) ACCUMULATION OF DEPOSITS (A PCV SYSTEM BY-PRODUCT) ON OR AROUND THE TB THROTTLE VALVE AND BORE.ODI CONCLUDES THAT THE TB PERFORMS IN A DEFECTIVE MANNER AFTER ANALYZING GM?S DATA SUBMISSIONS, AND TEST DATA COLLECTED BY THE VEHICLE RESEARCH AND TEST CENTER (VRTC).FIFTY-NINE CRASHES ARE ALLEGED TO HAVE OCCURRED AS A RESULT OF GM?S TB DEFECT.THE MAJORITY OF THE CRASHES INVOLVE A SINGLE VEHICLE, ENGAGING IN A CLOSE QUARTER VEHICLE MANEUVER (OR LOW SPEED), AND CAUSING ONLY MINOR PROPERTY DAMAGE.FOUR OUT OF THE FIFTY-NINE CRASHES INVOLVE INJURY, AND THOSE INJURIES WERE MINOR.ALTHOUGH GM?S TB IS DEFECTIVE, BASED ON THE EVIDENCE GATHERED, ODI HAS FOUND THAT THE ACCELERATOR PEDAL FORCE REQUIRED TO OPEN A STUCK THROTTLE VALVE IS NEGLIGIBLE, AND THE THROTTLE VALVE DOES NOT STICK IN THE OPEN POSITION.THEREFORE THIS ENGINEERING ANALYSIS (EA02-015) WILL BE CLOSED AT THIS TIME.THE CLOSING OF THIS INVESTIGATION DOES NOT CONSTITUTE A FINDING BY NHTSA THAT A SAFETY-RELATED DEFECT DOES NOT EXIST.FOR A DETAILED DISCUSSION OF THE TB COMPONENT AND TESTING, PLEASE SEE THE ATTACHED REPORT.
