LOOSING AIR PRESSURE FROM ALL 4 TIRES. TIRES IN GOOD SHAPE. COULD NOT UNDERSTAND WHY LOOSING PRESSURE. CAUSED VEHICLE TO PULL IN WHATEVER DIRECTION OF TIRE PRESSURE LOSS. SOMETIMES PULLING REALLY HARD AND MAKING VEHICLE HARD TO HANDLE. COULD NOT LET MY TEEN LEARNING TO DRIVE TO DRIVE THIS VEHICLE BECAUSE OF THIS. TOOK THE VEHICLE TO TIRE DEALER AND ACCORDING TO THEM THEY HAVE SEEN THIS A LOT WITH CHEVROLET AND THE CHROME DIPPED RIMS. WHAT IS GOING ON IS THE INSIDE OF THE CHROME RIMS IS RUSTING AND FLAKING AND CAUSING THE AIR TO SEEP OUT. THE RIMS HAVE TO BE SANDED DOWN AND PAINTED WITH A SPECIAL PAIN IN THE INSIDE AND ACCORDING TO THE DEALER THIS IS NOT A LONG TERM FIX AND THE RIMS WOULD HAVE TO BE REPLACED. THOUGH THEY LOOK GOOD THESE CHROME DIPPED RIMS COULD CAUSE A BIG PROBLEM FOR PEOPLE WHO ARE CLUELESS TO WATCHING AIR PRESSURE IN THEIR TIRES. I WATCH AROUND AND OFTEN SEE THESE TAHOE WITH LOW AIR PRESSURE IN THE TIRES. I HAPPEN TO WORK ON CARS MYSELF AND HAVE GOOD MAINTENANCE HABITS AND CAN SPOT THINGS SUCH AS LOW AIR PRESSURES. HAD I NOT I MAY BEEN IN A ACCIDENT BY NOW. I BOUGHT THIS VEHICLE USED BUT HAD ORIGINAL RIMS. ALSO WHEN WE BOUGHT THIS VEHICLE THE DEALER HAD TO PUT AIR IN ONE TIRE AND HAD IT CHECK BEFORE WE LEFT AND ALL LOOKED GOOD AND IT WAS JUST ASSUMED IT WAS FROM SITTING OR SOMETHING. *TR

CONTINUOUSLY HAVING TO FILL WITH COOLANT DUE TO LEAK. NO LEAK FROM HOSES ETC. THE PROBLEM COMES FROM A DEFECT IN HEADS THAT ARE PRODUCED BY CASTECH. WENT ON LINE TO RESEARCH THIS AND FOUND NUMEROUS COMPLAINTS ABOUT THIS AND GM/CHEVROLET WILL NOT FIX. EXTENDED WARRANTY COMPANIES WILL NOT FIX BECAUSE IT IS A DEFECTIVE PART. DEALERSHIPS WILL NOT TALK ABOUT IT BUT IF YOU TALK TO AN MECHANIC AT A DEALERSHIP AND DESCRIBE THE PROBLEM THEY ARE QUICK TO TELL YOU EXACTLY WHAT IT IS AND THAT IT IS A DEFECT. THE COOLANT SEEPS THROUGH THE POORLY MANUFACTURED CASTECH HEADS. CALLED SOME OF THE LOCAL MECHANICS AND THEY ARE SAYING THE SAME THING-DEFECTIVE PART. NOW LIKE I SAID I HAVE CHECKED ON LINE AND HUNDREDS OR MORE PEOPLE ARE HAVING THIS PROBLEM AND ARE HAVING TO HAVE THE HEADS REPLACED AND ENGINES AT OUT OF POCKET. I DID NOT SEE WHERE A LOT OF PEOPLE ARE COMPLAINING ON THIS SITE BECAUSE LIKE ME THEY DID NOT KNOW WHERE TO GO. I FOUND OUT FROM A LAWYER WHO ALSO HAD THIS PROBLEM TO COMPLAIN ON THIS SITE. HE JUST SIMPLY GOT RID OF HIS TAHOE. ONE SAID THEY WERE STUCK ON THE SIDE OF THE INTERSTATE WITH YOUNG KIDS AND NO PHONE AND NO WAY OF AFFORDING TO GETTING HOME FROM OUT OF TOWN. NOW THAT IS BAD. *TR

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.
