IN REFERENCE TO THE CURRENT INVESTIGATION OF GM TRUCKS AND SUVS FOR BRAKE PROBLEMS AT LOW SPEED. AS I SLOW DOWN OR HAVE TO STOP ON CLEAR/DRY ROADWAYS, I HAVE BEEN FORTUNATE NOT TO SMASH INTO THE VEHICLE IN FRONT OF ME OR TO CAUSE AN ACCIDENT BY GOING PAST THE STOP SIGN. I HAVE HAD THIS PROBLEM WITH MY 1999 CHEVY TAHOE SINCE DECEMBER, 2004 AND IT'S GETTING WORSE. IT USED TO HAPPEN JUST ONCE IN AWHILE, NOW IT HAPPENS 99% OF THE TIME WHEN I SLOW DOWN OR NEED TO STOP(AT A SPEED OF UNDER 10). I'M HAVING TO DOUBLE PUMP THE BRAKES AND STILL PRAY IT WILL STOP IN TIME. MOST REPAIR PLACES WANT TO REPLACE THE HUBS FOR A VERY HIGH PRICE OF $500 PER WHEEL OR MORE. I AM A MICHIGAN RESIDENT LIVING IN A "SALT BELT" STATE AND I'M NOT UNDERSTANDING WHY THE 1999 YEAR CHEVY TAHOE ISN'T COVERED UNDER THE RECALL FOR REPAIRING THE ANTI-LOCK BRAKES. I WOULD LIKE TO CHALLENGE THE NATIONAL HIGHWAY TRAFFIC SAFETY DEPARTMENT TO DRIVE MY VEHICLE AND THEN DETERMINE IF IT SHOULDN'T BE COVERED. *NM

EA02015 · Throttle Sticking Closed

Status: closed (inferred from source dates) · Vehicle Speed Control:linkages
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.
