THE BATTERY IN MY 1999 TAHOE HAS STARTED LEAKING FROM THE POSTIVE POST AND HAS DONE $ 480 DAMAGE TO THE CABLES AND STARTER MOTOR. THE SERVICE REP SAID THAT IT HAD BEEN LEAKING FOR A WHILE. I HAD IT IN FOR SERVICE JUST 10 DAYS BEFORE, AND NOTHEN WAS SAID ABOUT A LEAK. REAILABLE SAID THAT THE BATTERY IS A 6 YR. BATTERY, BUT WHEN IT IS PUT INTO A NEW VEHICLE THE WARRENTY IS FOR 3 YRS OR 36,000 MILES. HE SAID THAT DELCO HAS A PROBLEM WITH THEIR SIDE POST BATTERYS AND THEY ARE CHANGING OUT A LOT OF THEM, BUT BECAUSE I HAVE OVER 36,000 MILES, I WILL HAVE TO PAY FOR MY WORK. WHEN I BOUGHT THE VEHICLE, I WAS TOLD THAT IT WOULD NOT NEED A TUNE UP FOR 100,000 MILES AND IT HAS A MAINTANCE FREE BATTERY. HERE IT IS 28 MONTHS LATER AND ONLY 59,000 MILES AND THE BATTERY HAS DONE $480.00 OF DAMAGE, AND I FIND OUT IT IS HAPPING A LOT WITH DELCO BATTERYS. THIS CAN BE A HAZARD, BECAUSE THE ACID GETS ON DRIVEWAYS AND KIDS PLAY THERE. WHEN I BOUGHT THE VEHICLE, I ASK FRO A GM EXTENTED WARRENTY. I PAID $540.00 FOR THIS AND NOW I FIND OUT THAT I GOT SOME OTHER WARRENTY, NOT THE GM ONE AND IT DOESN'T COVER BATTERYS. WHAT IS THE CONSUMER SUPPOSE TO DO. I HAVE HAD THE REGULAR MAINTANCE REQUIRE BY GM DONE AT RELIABLE AND ONLY 10 DAYS EARILER IT WAS IN THEIR SHOP FOR OIL CHANGE AND GREASED AND I WAS NOT NOTIFIED OF THIS DAMAGE. ANY HELP YOU CAN GIVE ME WILL BE APPRECIATED. TO MAKE THING WORSE, I WAS CHARGED $34.95 BY RELIABLE TO RUN A DIAGNOSIS TEST TO DETERMINE THE BATTERY WAS LEAKING FROM THE POST. THE SERVICE REP RAISED THE HOOD WHEN I CARRIED IT IN AND SAID IT IS LEAKING FROM THE POST, THIS IS A PROBLEM WITH DELCO BATTERYS. I DON'T SEE WHY A TEST WAS THEN RAN.

Seat BeltsInjury
VEHICLE WAS INVOLVED IN ACCIDENT, THE FORCE TO THE SIDE IMPACT POSSIBLY CAUSED THE SEAT BRACKET TO BEND CAUSING THE SEAT BUCKLE ATTACHMENT BAR TO POP FREE FROM THE HOLDING PIN, THIS RESULTED IN THE BACK SEAT CONSUMER TO SOMERSAULT OVER THE BACK SEAT INJURING HIS FOOT.

THIS HAS HAPPENED TWICE TO ME . ONE TIME I LOST PARTIAL CONTROL INTO ONCOMING TRAFFIC AT 75MPH. THEY HAVE BLAMED THE TIRES (ALTHOUGH THEY REPLACED THEM 5 TIMES) THEY HAVE REALIGNED THE FRONT, BALANCED THE TIRES ENDLESSLY AND TRIED EVERYTHING THEY COULD THINK OF AND ACCOMPLISHED NOTHING. THIS IS TRULY A DANGEROUS TO HAVE ON THE ROAD AND IS GOING TO KILL SOMEONE ONE OF THESE DAYS. *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.
