231 reportsOCCASIONALLY WHILE BRAKING ON DRY AND CLEAR PAVEMENT MY 1999 CHEVY TAHOE WILL APPEAR TO ACTIVATE THE ABS SYSTEM. THIS OCCURS AT LOW SPEED AND EXTENDS THE STOPPING DISTANCE OF THE VEHICLE. FIRST OBSERVED ABOUT JANUARY 2005. *SC *JB
DT: THE VEHICLE ABS ENGAGED AT LOW SPEEDS AND HE TRUCK WOULD NOT STOP. TWO WHEEL SENSORS WERE THE CAUSE OF THE PROBLEM. *NM
MY 1999 CHEVY TAHOE HAS A CONDITION WHERE IF THE BRAKES ARE APPLIED WHILE THE VEHICLE IS TRAVELING AT A SPEED GREATER THAN 3.7 MPH BUT LESS THAN 10 MPH, I GET UNWANTED ANTI-LOCK BRAKE SYSTEM (ABS) ACTIVATION. NO ACCIDENTS HAVE BEEN CAUSE BY THIS YET, BUT IT HAS BEEN VERY CLOSE MANY TIMES.

ABOUT 2 MONTHS AGO THE ANTI-LOCK BRAKES ON MY TAHOE STARTED ACTIVATING AS I WAS SLOWING DOWN OR STOPPING ON CLEAR/DRY ROADWAYS.

ABOUT 2 MONTHS AGO THE ANTI-LOCK BRAKES ON MY TAHOE STARTED ACTIVATING AS I WAS SLOWING DOWN OR STOPPING ON CLEAR/DRY ROADWAYS. IT TOOK LONGER TO STOP, AND THE FIRST FEW TIMES IT HAPPENED I WAS FORTUNATE ENOUGH TO STOP WITHOUT SMASHING INTO THE CAR IN FRONT OF ME, OR THAT THERE WAS NO CAR IN THE INTERSECTION WHEN I WENT PAST THE STOP SIGN A FEW FEET. I WAS TOLD BY A MECHANIC FRIEND THAT IT WAS CAUSED BY A DIRTY OR DEFECTIVE ABS SENSOR. HE ALSO TOLD ME THAT GM DOES NOT SELL THE SENSOR SEPERATELY AND YOU HAVE TO BUY THE ENTIRE WHEEL HUB, WHICH COSTS AROUND $500 PER WHEEL. I HAVE NOT HAD IT REPAIRED YET DUE TO THE COST. I SIMPLY ALLOW MYSELF MORE TIME TO STOP. I WAS TOLD THAT I COULD DISABLE THE ANTI-LOCK BRAKES. I AM HESITANT TO DO THAT BECAUSE I FEEL I HAVE BETTER CONTROL WITH THE ANTI-LOCK BRAKES THAN CONVENTIONAL BRAKES WITH THE WEATHER IN THE AREA WHERE I LIVE.

CHEVY TAHOE 1999, WE HAVE OWNED THIS VEHICLE FOR FOUR YEARS AND PUT 40,000 + MILES ON IT, IT NOW HAS 102,000 MILES. IN THAT TIME FRAME WE HAVE HAD TO REPLACE THE FRONT ROTERS AND PADS FOUR TIMES. IN JANUARY OF 2002 I HAD AN ACCIDENT AT SLOW SPEED IN SLUSHY ROAD CONDITIONS WHERE THE VEHICLE DID NOT STOP OVER A TRAVEL DISTANCE OF 100'+/- IT WAS BLAMED ON DRIVER ERROR AND POOR ROAD CONDITIONS, SINCE THAT TIME WE HAD A COMPLETE FAILURE OF THE FRONT BRAKES WITH NO ACCIDENT AND FORTUNATELY NO INJURY.

REPLACEMENT FRONT BRAKE ROTORS INSTALLED ON A 1999 CHEVY TAHOE 2 DOOR AND DRIVEN APPROXIMATELY 100 MILES IN 15 MILE INCREMENTS RESULTED IN SIGNIFICANT INTEREFERENCE WEAR BETWEEN THE DISC BRAKE PAD BACKING PLATES AND THE CYLINDRICAL PORTION OF THE BRAKE ROTORS, WITH SIGNIFICANT HEAT GENERATION, NOISE, AND ODOR. SUBSEQUENT INSPECTION OF THE REPLACEMENT ROTORS AND THE OEM ROTORS REVEALED THAT THE REPLACEMENT ROTORS DIAMETER OF THE CYLINDRICAL PORTION THAT COVERS THE VEHICLE HUB WERE APPROXIMATELY 3/16 LARGER DIAMETER THAN THE OEM ROTORS. REPLACEMENT ROTORS HAVE BEEN RETURNED TO THE SELLER, PAUL DO AT CQUENCEMOTORSPORTS, 4933 PEARCE STREET, APT. B, HUNTINGTON BEACH, CA 92649. I BELIEVE THE ROTORS WERE MANUFACTURED IN CHINA, THEIR PART NUMBER IS 5569 MIN THK 30.86MM PT14 BT. FORTUNATELY, THE PROBLEM WAS DISCOVERED BEFORE SIGNIFICANT VEHICLE DAMAGE OCCURED. THE STOCK ROTORS WERE REINSTALLED WITHOUT INTERFERENCE. OLD PART UNAVAILABLE, IT WAS RETURNED TO SELLER UNDER WARRANTY.*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.
