I WAS 20 MILES FROM HOME GOING 64 MPH, ON A SLIGHT CURVE. I HEARD AND FELT THE BACK TIRE BLOW THE TIRE WALL FROM THE POINT OF TIRE WEAR TO THE CENTER. I WAS SHOCKED AT THE DAMAGE.. THE TAHOE LEANED SEVERELY TO THE RIGHT, BUT REMAINED UPRIGHT. I HELD THE STEERING WHEEL TIGHT AND STRAIGHT. AND EASED THE TAHOE TO THE SIDE OF THE ROAD. THE TAHOE WAS HARD TO CONTROL, BUT WAS ABLE TO GET IT TO THE SIDE OF THE HIGHWAY. WHEN THE TIRE BLEW THE TAHOE LEANED SEVERELY TO THE RIGHT. WHEN I GOT OUT OF THE TAHOE, I DISCOVERED THE TIRE HAD SUFFERED CATASTROPHIC FAILURE. THE TIRE COMPLELEY COLLASPED. THE SIDE WALL COMPLETELY BLOW AWAY. THIS TIRE WAS A FULL SIZE SPARE WITH ONLY 4000 MILES ON IT. SQUARE CHUNKS WHERE REMOVED FROM PART OF THE SIDEWALL. THERE WERE A NUMBER OF TEARS IN THE TIRE. FROM THE POINT OF THE TREAD TO THE CENTER.. I CALLED MY HUSBAND ON THE CELL PHONE; HE WAS IN THE MIDDLE OF A TRIAL (HE'S AN ATTORNEY). HE DROVE THE 20 MILES TO THE SITE AND HE WAS SHOCKED AT THE DAMAGE. WE CALLED A TOW TRUCK THE WHEEL ITSELF WAS DAMAGED. AT THIS TIME WE DO NOT KNOW IF THE REAR AXLE IS DAMAGED, IT WILL BE CHECKED OUT TOMORROW. IT'S AT THE DEALERSHIP NOW. NO ONE HAD SEEN ANYTHING LIKE IT. THIS WAS NOT A FLAT, IT WAS AN ENTIRE BLOWOUT. WE STILL HAVE POSSESSION OF THE DEFECTIVE TIRE AND PHOTOS WERE TAKEN AT THE SCENE AND AT THE DEALERSHIP.*AK (TIRESIZE: P2451/76R1)( DOT NUMBER: TIRE SIZE: P2451/76R1 )

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.
