THIS DOES NOT INVOLVE A CRASH RELATED COMPLAINT, IT MAY BE CONSIDERED A MINOR DEFECT RELATED ISSUE. I AM A REPAIR FACILITY, WE HAVE A TRANSMISSION REMOVED FROM A 2003 CHEVY CAVALIER FOR REPAIR, THE WARRANTY COMPANY THAT I AM WORKING WITH NEEDED TO VERIFY MILES, SO WE HOOKED UP THE BATTERY WITH THE TRANSMISSION OUT OF THE CAR, THE ODOMETER MOVED FORWARD 17 MILES. EVERY TIME I HOOK UP THE BATTERY AND DISCONNECT IT, THE ODOMETER MOVES FORWARD 17 MILES. I THOUGHT MAYBE IT WAS AN ISOLATED ISSUE TO THIS CAR, SO I DISCONNECTED THE TRANSMISSION WIRING HARNESS TO A 2005 CHEVY CAVALIER, THEN CONNECTED AND RECONNECTED THE BATTERY, IT ALSO ROLLED THE ODOMETER FORWARD WITH EACH CONNECTION AT A RATE OF 8 MILES. NO ONE AT GM HAS EVER HEARD OF THIS, I WILL CONTINUE TO TEST OTHER PRODUCTS TO SEE WHAT HAPPENS. *TR

COMING HOME FROM MILWAUKEE AT 12:30 AM WITH SON AFTER SEEING RACE IN SLINGER, WI. ON INTERSTATE, CAR LOST COMPLETE ENGINE POWER AND BECAME DEAD. CLOSEST GM DEALERSHIP IN WATERTOWN, WI WENT OUT OF BUSINESS LAST YEAR (PER TOW TRUCK DRIVER). HAD TOWED TO DEALERSHIP WHERE THEY DIAGNOSED A BAD FUEL PUMP AND A PRICE OF OVER $800. CAME TO PICK UP WITH A TRAILER AND ASKED FOR HELP PUSHING CAR ON TRAILER. THEY SAID YOU COULD DRIVE IT UP AS THE MECHANIC TAPPED THE FUEL TANK AND IT STARTED. DROVE AROUND THE BLOCK A FEW TIMES LAST WEEK WITH NO PROBLEMS. I EXPLAINED THIS TO GM, TOLD THEM ABOUT THEIR POOR DESIGN AND THAT THIS IS NOT SAFE BECAUSE IT WILL FAIL AT ANY TIME AND COULD CAUSE A MAJOR ACCIDENT. WAS GIVEN CASE #71-648948392 (TOLD NO RECALLS WERE AVAILABLE PER MY VIN #). CHECKED ON INTERNET (TOPIX.COM) AND OVER 400 HAVE HAD SIMILAR PROBLEMS. *TR

ON MAY 14, 2004 THE OFFICE OF DEFECTS INVESTIGATION (ODI) OPENED A PRELIMINARY EVALUATION (PE04-043) BASED ON CONSUMER COMPLAINTS ALLEGING THAT THE BRAKE/TAIL TURN SIGNAL LAMPS WOULD NOT OPERATE PROPERLY WHEN EITHER THE TAIL LIGHTS WERE TURNED ON, THE BRAKE PEDAL WAS DEPRESSED, OR WHEN THE TURN SIGNAL SWITCH WAS ACTIVATED.ON SEPTEMBER 14, 2004 ODI UPGRADED PE 04-043 TO AN ENGINEERING ANALYSIS (EA04-028).GM STATES THAT SOME BRAKE/TAIL/TURN SIGNAL LAMP BULBS CAN PREMATURELY BECOME INOPERATIVE DUE TO EXCESSIVE HEAT BUILDUP WITHIN THE BULB SOCKETS.THE CAUSE OF THE EXCESSIVE HEAT BUILD UP WAS DETERMINED TO BE A LACK OF THERMAL GREASE PLACED IN BETWEEN THE BULB AND THE SOCKET. BY LETTER DATED OCTOBER 27, 2004 GM NOTIFIED NHTSA THAT IT WILL CONDUCT A SAFETY RECALL (NHTSA # 04V524) COVERING ALL MY 2003 VEHICLES.GM DEALERS WILL INSPECT THE REAR LAMP BULB SOCKET ASSEMBLIES AND APPLY THERMAL GREASE TO THEM OR REPLACE THEM WITH NEW ASSEMBLIES WITH THERMAL GREASE ALREADY ATTACHED.MODEL YEAR 2004 AND NEWER VEHICLES HAVE THE THERMAL GREASE INSTALLED FROM THE FACTORY. THE ACTION TAKEN BY GM IS SUFFICIENT TO RESOLVE THE ISSUES RAISED BY THIS INVESTIGATION.ACCORDINGLY, THIS INVESTIGATION IS CLOSED.
