WHILE DRIVING MY 2001 CHEVROLET 2500 HD CREW CAB 4X4 SOUTH ON US 59 IN HOUSTON TEXAS THE TREAD FULLY SEPARATED OFF THE RIGHT REAR FIRESTONE STEELTEX A/T 245/75R16, LOAD RANGE E, DOT NO.VN11BAC5300 AT APPROXIMATELY 10:30 ON APRIL 21, 2004. JUST PRIOR TO SEPARATION, TRUCK STARTED VIBRATING (SPEED WAS APPROXIMATELY 65 MPH). THE VIBRATION THEN BECAME VIOLENT FOLLOWED BY LOUD NOISES. AT THIS TIME I NOTICED LARGE CHUNKS OF RUBBER FLYING ALL OVER THE HIGHWAY, FOLLOWED BY WHAT APPEARED TO BE THE ENTIRE TREAD. THE ENTIRE EVENT ONLY LASTED SECONDS. I PULLED OVER AS SOON AS POSSIBLE FINDING THE TIRE STILL FULLY INFLATED, BUT MISSING THE ENTIRE TREAD. THERE WERE NO INJURIES, BUT DAMAGE HAS BEEN ESTIMATED AT $4018.38. I HAVE ROTATED MY TIRES ON REGULAR BASIS AND MAINTAINED CHEVROLETS RECOMMENDED PRESSURES. I CAN PROVE THE TIRE THAT LOST IT'S TREAD HAD BEEN AT 80 PSI FROM DECEMBER 2003 TO DAYS PRIOR TO THE SEPARATION. I FILED A CLAIM WITH BRIDGESTONE/FIRESTONE NORTH AMERICAN TIRE, LLC AND PAID TO SHIP THE TIRE TO THEM. THEIR RESPONSE DATED 5/5/2004, CLAIM REF. NO. [XXX] WAS "WE HAVE CAREFULLY INSPECTED YOUR TIRE. WE DID OBSERVE SIGNS THAT THE TIRE HAD BEEN OPERATED FOR AN UNKNOWN PERIOD OF TIME WHILE BEING IN AN OVER-DEFLECTED STATE CAUSING THE DETACHMENT YOU EXPERIENCED... WE MUST RESPECTFULLY DENY YOUR REQUEST FOR COMPENSATION." MY TIRES HAVE BEEN AT CHEVROLET RECOMMENDED AIR PRESSURE SINCE I BOUGHT THIS TRUCK NEW. I HAVE ALSO NEVER EXCEEDED THE GVWR, GAWR FRT OR GAWR RR LOAD RATINGS. WHAT I HAVE FOUND OUT THROUGH THE INTERNET IS THERE SEEMS TO BE LOTS OF OTHER FOLKS THAT HAVE HAD THE SAME PROBLEM. I AM IN THE PROCESS OF TAKING THEM TO SMALL CLAIMS COURT VS. FILING WITH MY INSURANCE BECAUSE FIRESTONE HAS A DEFECTIVE PRODUCT. I HOPE THIS AGENCY CAN HELP PROTECT CONSUMERS FROM FUTURE INJURIES AND DRIVING UP OUR INSURANCE COSTS. IF ALLOWED, POST MY EMAIL AS [XXX] - I WOULD LIKE TO HEAR FROM OTHERS WHO HAVE BEEN THRU THIS.*AK INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552

IN A LETTER DATED NOVEMBER 7, 2007, GENERAL MOTORS (GM) REPORTED TO THE OFFICE OF DEFECTS INVESTIGATION (ODI) THAT IT WILL CONDUCT A SAFETY RECALL (07V-521) TO REPLACE THE CRANK POSITION SENSOR (CKP) IN APPROXIMATELY 12,000 MODEL YEAR (MY) 2001 CHEVROLET SILVERADO AND GMC SIERRA VEHICLES EQUIPPED WITH 8.1 LITER ENGINES MANUFACTURED ON OR BEFORE NOVEMBER 15, 2000.ACCORDING TO GM, THE CKP CAN FAIL INTERMITTENTLY OR PERMANENTLY.A PERMANENT CKP FAILURE WOULD RESULT IN AN ENGINE STALL WITHOUT RESTART.AN INTERMITTENT CKP FAILURE COULD CAUSE THE SERVICE ENGINE SOON LIGHT TO ILLUMINATE, THE VEHICLE TO RUN ROUGH OR THE ENGINE TO STALL BUT ALLOWS RESTART.AS A REMEDY, AN IMPROVED CKP WILL BE INSTALLED IN THE SUBJECT VEHICLES.THE RECALL CAMPAIGN WILL START IN DECEMBER 2007. DURING THE PRELIMINARY EVALUATION (PE06-016), AND THIS EA INVESTIGATION, GM AND ODI INDEPENDENTLY CONDUCTED DETAILED REVIEWS OF CERTAIN FIELD DATA TO UNDERSTAND THE NATURE AND RATE OF SUBJECT VEHICLE STALLING DUE TO CKP FAILURES.GM AND ODI REVIEWED GM'S WARRANTY CLAIMS FOR THE CKP WITH THE OBJECTIVE OF ASCERTAINING AN ESTIMATE OF THOSE CLAIMS REPRESENTING AN ENGINE STALL WHILE DRIVING.THE CKP WARRANTY CLAIMS WITHOUT VERBATIM TEXT WERE THE LARGEST SEGMENT OF WARRANTY CLAIMS.USING THOSE CLAIMS, GM SURVEYED VEHICLE OWNERS TO GATHER ADDITIONAL INFORMATION TO DETERMINE IF THE CLAIM WAS ASSOCIATED WITH A STALL WHILE DRIVING EVENT.BASED ON THE SURVEY, GM ESTIMATED THAT APPROXIMATELY 49% OF ALL WARRANTY REPAIRS FOR THE CKP INVOLVED A STALL WHILE DRIVING.ODI?S REVIEW OF GM'S SURVEY DATA PRODUCED A HIGHER ESTIMATE (71%) FOR STALL WHILE DRIVING.GM FURTHER ESTIMATED THE RATE OF STALL WHILE DRIVING FOR THE SUBJECT VEHICLES OVER TIME.IT ESTIMATED STALLING WHILE DRIVING RATES OF 1.6%, 4.6% AND 8.9% AT 1, 3 AND 6 YEARS IN SERVICE RESPECTIVELY.ODI'S REVIEW OF THE GM'S SURVEY DATA FINDS HIGHER ESTIMATED STALL WHILE DRIVING RATES OF 2.2%, 6.8% AND 13% AT 1, 3 AND 6 YEARS IN SERVICE RESPECTIVELY. ODI ALSO CONDUCTED A SURVEY OF VEHICLE OWNERS USING CONSUMER COMPLAINTS REPORTED TO BOTH ODI AND GM.THE OBJECTIVE WAS TO ASCERTAIN THE POTENTIAL SAFETY CONSEQUENCES OF AN ENGINE STALL DUE TO THE ALLEGED DEFECT.WITH RESPECT TO THE ABILITY TO RESTART THE VEHICLE AFTER A STALL, 11% REPORTED IMMEDIATE RESTART, 69% REPORTED DELAYED RESTART AND 20% REPORTED NO RESTART.OVER HALF NOTED AT LEAST ONE ENGINE STALL INCIDENT AT SPEEDS IN EXCESS OF 40MPH. ABOUT ONE-THIRD NOTED THE VEHICLE WAS STRANDED EITHER PARTIALLY OR FULLY IN A LANE OF TRAFFIC AFTER THE ENGINE STALL.ALL OF THE CONSUMERS SURVEYED NOTED MULTIPLE STALLING EVENTS PRIOR TO PROPER DIAGNOSIS AND REPLACEMENT OF THE CKP.BASED ON GM'S DECISION TO CONDUCT A SAFETY RECALL, THIS INVESTIGATION IS CLOSED.
