ABS ENGAGES ON MY CHEVROLET TAHOE AS I COME TO A STOP, PREVENTING ME TO STOP IN A REASONABLY EXPECTED DISTANCE. I HAVE A 1999 TAHOE THAT SEEMS TO HAVE THE EXACT SAME PROBLEM ADDRESSED BY NHTSA RECALL CAMPAIGN NUMBER 05V37900, GM RECALL NUMBER 05068. THE PROBLEM OCCURS EVERY TIME I COME TO A COMPLETE STOP. AS THE VEHICLE SLOWS TO 1 OR 2 MPH THE ABS ENGAGES AND INCREASES THE STOPPING DISTANCE. THE VEHICLE WAS PURCHASED AND REGISTERED AND USED IN NEW YORK FROM NEW TILL PRESENT. NEW YORK IS ONE OF THE SALT BELT STATES THAT IS COVERED IN THE RECALL LISTED ABOVE. I HAVE CONTACTED GM AND THEY TOLD ME THE RECALL DID NOT APPLY TO MY PARTICULAR TAHOE. I BOUGHT THE VEHICLE BRAND NEW IN 1998 . THE REP AT GM COULD NOT EXPLAIN WHY MY PARTICULAR VEHICLE WAS NOT COVERED BY THE RECALL..THE VEHICLE WAS LOOKED AT BY A GM MECHANIC. HE SAID THE SENSORS WOULD HAVE TO BE REMOVED, CLEANED, ANTI-RUST MATERIAL APPLIED, AND REPLACED. THE WORK HAS NOT BEEN DONE YET. *TR

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.
