IT SEEMS THAT THE ELECTRICAL CONNECTION IS FAULTY AND MELTS. IT SEEMS THAT SOME PEOPLE HAVE HAD FIRES. WHEN I SEARCHED ONLINE I FOUND THOUSANDS OF PEOPLE WITH THE SAME PROBLEM. I'M JUST GLAD THAT I WAS NOT ONE OF THE UNFORTUNATE PEOPLE THAT HAD A FIRE. *TR

NO START AND STALL CONDITION ON MY 2003 CAVALIER. IT STARTED WITH A NO START. AFTER READING ON THE INTERNET ABOUT SOMEONE POUNDING ON THEIR FUEL TANK I ATTEMPTED THIS AND TRIED TO RESTART THE CAR AND IT RESTARTED. THIS FREQUENCY OF NO STARTS HAS INCREASED. RECENTLY WHILE DRIVING, THE CAR STALLS AS IF THE CAR IS OUT OF GAS. ONCE IT STALLS IT WILL NOT START. I BANGED ON THE BOTTOM OF THE FUEL TANK AND ATTEMPTED TO RESTART THE CAR AND IT WOULD START. THE FREQUENCY OF THE STALLS ALSO ARE INCREASING AND OCCURS WHEN DRIVING REGARDLESS OF SPEED. THE LAST STALL WAS ON OCT. 22, 2008 WHILE TRAVELING AT 50 MPH. THE RESTARTS ARE BECOMING MORE DIFFICULT. IT NOW REQUIRES ONE PERSON TO TURN THE IGNITION WHILE ONE IS UNDER THE CAR POUNDING ON THE FUEL TANK. IT APPEARS TO BE A FAULTY FUEL PUMP. THE ENGINE TURNS OVER BUT APPEARS TO NOT BE RECEIVING GAS. THE FUEL FILTER HAS ALREADY BEEN REPLACED. *TR

I HAVE A 2003 CHEVY CAVALIER WITH 53,000 MILES ON IT, I HAVE ALWAYS CHANGED THE FUEL FILTERS, NEVER LET THE FUEL GO UNDER 1/4 TANK. ONE DAY I WAS DRIVING, AND THE CAR DIED WITH NO ALERT. I LOST ALL POWER, POWER STEERING, POWER ASSISTED BRAKES, EVERYTHING IN THE MIDDLE OF THE ROAD GOING 60 MPH WITH TRAFFIC ALL AROUND ME. I COULD NOT PRESS THE BRAKES HARD ENOUGH TO STOP THE VEHICLE SO I ACTIVATED MY 4-WAY FLASHERS AND COASTED OFF TO THE SIDE OF THE ROAD AND USED MY EMERGENCY BRAKE TO COMPLETELY STOP. I WAS 10 MILES AWAY FROM MY HOME SO I HAD THE VEHICLE TOWED TO MY HOUSE UNTIL I COULD FIGURE OUT WHAT TO DO WITH IT, THAT TOW BILL WAS $120.00. I AM UNABLE TO DRIVE TO WORK AND LOOSING ABOUT $100 A DAY AND NOW I WILL HAVE TO TOW THE VEHICLE TO A REPAIR SHOP BECAUSE OF THIS FAULTY PART AND SPEND APPROXIMATELY $900 ON A PROBLEM THAT I HAVE READ OCCURS MORE OFTEN THAN IT SHOULD. *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.
