ORIGINAL PROBLEM: MY 2002 YUKON XL WAS RUNNING POORLY WHEN THE WEATHER TURNED COLD - BELOW 30 DEGREES. PROBLEM DIAGNOSED AS FAULTY INTAKE GASKETS DUE TO IMPROPER DESIGN. SECOND PROBLEM: IT BECAME HARD TO START, AND A COUPLE OF DAYS LATER, IT WOULD NOT START AT ALL. PROBLEM DIAGNOSED AS FAULTY FUEL PUMP. BOTH PROBLEMS ARE BECAUSE THEY WERE DESIGNED FOR USE WITH ETHANOL OR UNLEADED GAS. I ONLY USE UNLEADED (NEVER HAVE SEEN A STATION THAT SELLS ETHANOL). IF YOUR GM VEHICLE HAS A 5.3L V8 ENGINE, AND THE VIN HAS A Z IN THE 8TH POSITION, BE AWARE THAT THIS MIGHT HAPPEN TO YOUR VEHICLE. IF NOT UNDER WARRANTY, IT IS VERY COSTLY! THE GASKETS AND THE FUEL PUMP ALONE COST OVER $630. LABOR OVER $500. *NM
DT: THE CONSUMER BELIEVES THAT THERE ARE ELECTRICAL PROBLEMS WITH THE GMC. THE WATER PUMP WAS OUT, THE RADIO HAS QUIT WORKING 5 TIMES, AND HAS BEEN REPLACED 4 TIMES, THE WINDOWS ON THE PASSENGER QUIT, AND THE REGULATOR WAS REPLACED 4 TIMES. THIS HAS HAPPENED AT 35,000 MILES. *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.
