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

I BROUGHT MY 1999 CHEVROLET TAHOE TO ALEXANDRIA BUICK-PONTIAC-GMC IN ALEXANDRIA, VIRGINIA ON DECEMBER 14, 2005 BECAUSE THE ABS LIGHT KEPT COMING ON IN THE DASHBOARD. MECHANIC DIAGNOSIS WAS SPEED SENSORS WERE MISSING. HE REPLACED THE HUB ASSEMBLIES AND SPEED SENSORS. TOTAL REPAIR WAS $1064.54. I THEN FOUND OUT THAT A RECALL ON THE PROBLEM I HAD JUST REPAIRED WAS GOING ON IN THE "RUST BELT" STATES AND CANADA. THE RECALL WAS FOR THE WHOLE NORTHEAST PART OF THE COUNTRY DOWN TO AND INCLUDING WASHINGTON DC. I WORK IN WASHINGTON AND LIVE ABOUT 5 MILES FROM THE CITY. I WROTE THE GM CLAIMS DEPARTMENT WITH COPIES OF EVERY RECEIPT AND A COPY OF THE RECALL LETTER. THEY CONTACTED ME AND TOLD ME THE REPAIR WAS INDEED ONE INCLUDED WITHIN THE RECALL, BUT THEY WERE DENYING THE CLAIM BECAUSE I LIVE IN VIRGINIA AND THE RECALL IS ONLY VALID IN "SALT BELT" STATES OF CONNECTICUT, DELAWARE, ILLINOIS, INDIANA, IOWA, MARYLAND, MASSACHUSETTS, MAINE, MICHIGAN, MINNESOTA, MISSOURI, NEW HAMPSHIRE, NEW JERSEY, NEW YORK, OHIO, PENNSYLVANIA, RHODE ISLAND, VERMONT, WEST VIRGINIA, WISCONSIN AND THE DISTRICT OF COLUMBIA. I WANT THE RECALL TO BE OPENED BACK UP AND TO INCLUDE ADDITIONAL STATES. I SPEND EVERY SINGLE DAY IN WASHINGTON, WHAT MAKES MY CLAIM ANY DIFFERENT FROM THE PERSON THAT LIVES 5 MILES AWAY FROM ME, BUT HAPPENS TO LIVE ACROSS THE STATE BORDER? WHAT IS DIFFERENT FROM SOMEONE WHO LIVES IN WASHINGTON AND WORKS IN VIRGINIA? SINCE MY HOME ADDRESS WAS VIRGINIA, MY CLAIM WAS DENIED. THE RECALL CAMPAIGN # IS 05V379000. *NM THE ENGINE LIGHT ILLUMINATED, THE SERPENTINE BELT WAS REPALCED. THE WATER PUMP WAS LEAKING ABD THE PINION SEAL WAS REPLACED. UPDATED 02/09/06. *JB

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.
