CONSTANT ACTIVATION OF ABS BRAKES DUE TO CORROSION BETWEEN THE FRONT HUB/BEARING ASSEMBLY AND/OR THE SPEED SENSOR BEING DEFECTIVE. THIS ISSUE IS BEING ADDRESSED BY GM ON SOME VEHICLES BUT THEY WON'T FIX MINE BECAUSE THEY SAY IT'S NOT IN THE VIN NUMBER RANGE. THE PROBLEM IS VERY REAL AND VERY DANGEROUS. IT STARTED ALMOST 12 MONTHS AGO, AND I WAS TOLD TO WAIT FOR THE STATE OF WISCONSIN TO BE ADDED TO THE RECALL LIST, THEY HAVE ADDED WISCONSIN BUT HAVE SELECTED CERTAIN VIN NUMBERS ONLY THAT THE BULLETIN APPLIES TO. *NM

I OWN A 1999 CHEVROLET TAHOE. IT HAS A SEVERE BRAKE PROBLEM. SOMETIMES WHEN YOU ARE GOING UNDER 40 AND STEP ON THE BRAKES THE ABS SEEMS TO ACTIVATE MAKING A LOUD NOISE AND THE VEHICLE DOES NOT WANT TO STOP UNLESS YOU STAND ON THE BRAKES AND THEN IT STOPS SLOWLY. I HAD A COMPLETE BRAKE JOB DONE AND IT DIDN'T GET ANY BETTER EVEN THOUGH I TOOK IT BACK 2 MORE TIMES. WHILE I WAS ON THE INTERNET TRYING TO FIND A SITE THAT MIGHT BE ABLE TO TELL ME WHAT WAS WRONG I RAN ACROSS A SITE CALLED WWW.OHIOLEMONLAW.COM. THEY LISTED MY VEHICLE MODEL AND YEAR AS HAVING A RECALL FOR EXACTLY THE PROBLEM I WAS HAVING. I THEN CHECKED WITH GM AND MY LOCAL CHEVROLET DEALERSHIP AND THEY WERE BOTH AWARE OF THE PROBLEM AND THE RECALL BUT SAID MY VEHICLE'S VIN WAS NOT INCLUDED IN THE RECALL. IF THERE WAS A RECALL ON THE 1999 TAHOE FOR EXACTLY THE SAME PROBLEM AS MY 1999 TAHOE THEN I FEEL THAT MY VEHICLE SHOULD BE COVERED UNDER THAT RECALL. I ALSO LOOKED UNDER THE NHTSA SITE AND FOUND A RECALL CAMPAIGN NUMBER 05V379000 FOR EXACTLY THE SAME PROBLEM I AM HAVING. PLEASE LET ME KNOW WHAT MY OPTIONS ARE. MY VIN # IS [XXX] AND I AM THE ORIGINAL OWNER THANK YOU. *NM UPDATED 07/16/2012 *JS INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

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.
