I MANAGED TO COAST TO AN EXIT RAMP WHERE MY CAR COMPLETELY STALLED AT THE BOTTOM OF THE RAMP IN THE MIDDLE OF A LANE. I HAD TO CALL AND HAVE MY CAR TOWED TO THE DEALERSHIP. IT WAS THE DEALERSHIP THAT DETERMINED THE FUEL PUMP WAS FAULTY AND NEEDED TO BE REPLACED. IT WAS REPLACED AND HAS BEEN FINE SINCE. THIS REPAIR COST ME APPROXIMATELY $800. *TR

FORTUNATELY, I WAS ABLE TO RESTART IT, BUT WITHIN LESS THAN 30 SECONDS, IT STALLED OUT AGAIN. I WAS FORTUNATE ENOUGH TO BE ABLE TO PULL INTO A PARKING LOT AND OUT OF THE WAY OF OTHER CARS. HOWEVER, AT THAT POINT, THE CAR WOULD NOT START UP AGAIN. I HAD TO HAVE THE CAR TOWED AND THE FUEL AND AIR FILTER REPLACED. BEYOND THAT, I WAS TOLD THE FUEL GAUGE DID NOT READ CORRECTLY. THE CAR RAN FINE AFTER THAT, BUT A COUPLE OF WEEKS LATER THE CAR STALLED OUT AGAIN. I'VE BEEN TOLD I NEED A NEW FUEL PUMP. AMAZING...THE CAR IS ONLY 5 YEARS OLD! *TR

2003 CHEVY CAVALIER SUDDENLY LOSS POWER ON MAJOR STREET. MY DAUGHTER WAS DRIVING AND TODDLER GRANDSON WAS RIDING IN HIS CAR SEAT IN THE BACK SEAT. THANKFULLY NO ONE WAS BEHIND HER TO REAR END HER AND SHE WAS NEAR THE POLICE STATION SO A POLICE OFFICER ASSISTED HER OFF OF THE ROAD. THE FUEL PUMP WAS REPLACED THE FOLLOWING DAY AT THE COST OF $557.00. THE VEHICLE ONLY HAS 40K MILES. I'VE NEVER REPLACED A FUEL PUMP ON ANY CAR THAT I'VE EVER OWNED EVEN THOSE THAT I KEPT LONG ENOUGH TO HAVE 4 TIMES THAT NUMBER OF MILES. AFTER RESEARCHING AND FINDING THAT TOO MANY OWNERS OF THIS MAKE, MODEL AND YEAR HAVE HAD THIS PROBLEM FOR IT TO BE INCIDENTAL I AM FILING THIS COMPLAINT AS WELL. *TR

THE NEXT TIME I HAD AN ISSUE, THE CAR WOULD NOT START. THE STARTER WOULD CLICK, BUT THERE WAS AN IGNITION ISSUE. RELIABLE CHEVROLET (DALLAS) REPORTED THAT THE FUEL PUMP HAD FAILED. THEY REPLACED IT FOR $900 INCLUDING LIFETIME WARRANTY ON THE PART, THEN THE NEXT WEEK AN IGNITION SENSOR FAILED. THIS WAS REPLACED FREE-OF-CHARGE FOR MISSING IT ON THE DIAGNOSTIC. *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.
