WE TOOK THE VEHICLE IN ON 9/07/05 FOR AN INSPECTION AND IT DID NOT PASS DUE TO THE SENSORS. WE WERE ADVISED TO PAY FOR REPAIR ($500) AND SEND RECEIPT IN WHEN OUR VIN NUMBER WAS LISTED ON THE RECALL....TO THIS DAY GM CLAIMS WE DO NOT QUALIFY AND I WOULD LIKE TO MAKE A FORMAL COMPLAINT THAT WE SHOULD BE REIMBURSED FOR OUR REPAIRS. *NM

WHILE TRAVELING WEST ON I-10, IN JEFFERSON COUNTY, I FELT A VIBRATION AND WAS SLOWING DOWN WHEN THE LEFT REAR TIRE FAILED. MY VEHICLE SWERVED AND I PULLED OFF THE SIDE OF THE ROAD. THE RUBBER ON THE TIRE SEPARATED AND EXPOSED THE INFLATED TIRE. THE TIRE MAINTAINED ITS AIR PRESSURE AND SOME OF THE STEEL BELT WAS VISIBLE BUT THE TREAD WAS MISSING. THE VEHICLE TRAVELING BEHIND ME, APPARENTLY, OVER STEERED IN AN EFFORT TO AVOID MY DISCARDED RUBBER AND DROVE OFF THE ROADWAY. EMERGENCY PERSONNEL ASSISTED THIS DRIVER. THE DISCARDED RUBBER DAMAGED THE REAR BUMPER AND TAILGATE OF MY VEHICLE. THE TIRE WAS SENT TO FIRESTONE'S COMPLAINT DEPARTMENT AT BFNT LLC ( REF # 917284) AND THEY EVALUATED IT. THEY ARE NOT CLAIMING THE TIRE WAS DEFECTIVE. MY VEHICLE IS NOT USED OFF ROAD AND THE MODEL NUMBER IS LT245/75R16, STEELTEX RADIAL R4S II. *NM

TRANSMISSION DOES NOT PERFORM CORRECTLY. TRANSMISSION DOES NOT ENGAGE CORRECTLY. MOST RECENT OCCURRENCE TRANSMISSION SHIFTED TO NEUTRAL WHILE BEING OPERATED AND WOULD NOT GO BACK INTO GEAR. TRANSMISSION FINALLY SHIFTED TO FIRST GEAR, BUT WOULD NOT CHANGE TO ANOTHER GEAR. THERE HAVE BEEN SOFTWARE UPGRADES TO THIS TRANSMISSION, BUT THAT IS NOT CONSIDERED A REPAIR FOR GM. GM SAYS THERE IS NOTHING THEY CAN DO BECAUSE IT IS NOT UNDER WARRANTY ANYMORE, BUT PROBLEM STARTED BEFORE VEHICLE WAS OUT OF WARRANTY. VEHICLE HAS BEEN TAKEN TO A DEALERSHIP FOR CONCERNS MULTIPLE TIMES, BUT NOTHING WAS REPAIRED. IT WAS STATED THAT WAS A COMMON PROBLEM FOR THAT YEAR OF VEHICLE. NOW THEY THINK THE PROBLEM IS PIN POINTED, BUT THE REPAIR COST WOULD BE CHARGED TO ME SINCE IT IS OUT OF WARRANTY. *JB

THE CONSUMER CONTINUED DRIVING THE VEHICLE HOME, AND LATER HAD THE VEHICLE TOWED TO A SERVICE DEALER. THE SERVICE DEALER STATED THE VEHICLE NEEDED TO HAVE BRAKE PADS, ROTORS, AND CALIPERS ON THE BACK. ON THE FRONT OF THE VEHICLE THE ROTORS WILL NEED TO BE TURNED. THE ABS FRONT SPEED SENSOR WAS DEFECTIVE. THE SERVICE DEALER HAD TO REPLACE THE ABS FRONT SPEED SENSOR, REPLACE AT LEAST ONE ROTOR ON THE BACK, A BACK CALIPER, AND THE FRONT ROTORS WILL NEED TO BE TURNED, AND MAY HAVE TO REPLACE THE FRONT BRAKE PADS. *AK

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.
