EVENTS LEADING UP TO THE FAILURE: 2002 YUKON 73,000 MILES. NO PREVIOUS EVENTS LEADING UP TO THE PROBLEM. FAILURE/CONSEQUENCES: 2002 YUKON: I STARTED MY CAR AND ABS LIGHT STAYED ON. WHILE DRIVING, I COULD FEEL AN ABNORMAL VIBRATION THROUGHOUT MY CAR. (WITH MY TWO SMALL CHILDREN, WE PULLED OFF TO THE SIDE OF THE ROAD ON THE RIGHT OF WAY. I CUT OFF MY CAR (REMOVED KEY OUT OF IGNITION) AND THE CAR SOUNDED LIKE IT WAS STILL ON. CORRECT THE PROBLEM: I CALLED MY GMC DEALER IN AUSTIN TEXAS WHERE I HAD PURCHASED THE VEHICLE AND THE SERVICE MANAGER TOLD ME THAT HE HAS SEEN MANY INCIDENTS SUCH AS THIS. HE INDICATED THAT IF I LEFT THE ABS MOTOR RUNNING, THAT MY BATTERY WOULD DIE AND/OR THE MOTOR WOULD RUIN. SO, HE INSTRUCTED ME TO RAISE THE HOOD AND REMOVE THE 60AMP ABS FUSE. BY DOING SO, THE VIBRATION/MOTOR STOPPED. HE SAID TO BRING IT INTO THE GARAGE FOR SERVICE. HIS INITIAL GUESS WAS THAT IT WAS THE ABS MODULE OR EBCM NEEDED TO BE REPLACED. BECAUSE MY VEHICLE WAS NO LONGER IN WARRANTY, HE ESTIMATED THAT IT COULD COST ANYWHERE BETWEEN $1100.00-1900.00 DOLLARS. I HAVE DONE RESEARCH ON THE INTERNET AND THERE ARE MANY 1999-2004 GM SUVS AND TRUCKS WHICH HAVE EXPERIENCED THIS PROBLEM. I AM REQUESTING THAT A RECALL BE PLACED FOR THESE MODULES. *TR

TOOK CAR TO BRAKE CHECK, HAD TO HAVE BOLTS ON HUB BEARING REPLACED. CONTACTED GMC TO HELP SHARE IN COST OF REPAIR, AS THERE HAS BEEN A RECALL (2002 GMC YUKON RECALL ID FROM NHTSA: 05V379000 ) IN CERTAIN "SALT BELT STATES", DUE TO CORROSION. THEY REFUSED ANY ASSISTANCE BECAUSE 1) CAR IS OUT OF WARRANTY (I HAVE 82,000 MILES ON IT), 2) I DIDN'T TAKE IT TO A GM DEALER, AND 3) THERE HASN'T BEEN A RECALL ISSUED SPECIFICALLY FOR MY CAR! *NM

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.
