THE SERVICE ENGINE SOON, ABS AND TRACK OFF LIGHTS BEGAN TURNING OFF AND ON PERIODICALLY IN MID MAY 2005. THE CAR WAS TAKEN TO THE DEALER ON MAY 19, 2005 FOR ROUTINE SERVICE AND FOR THE WARNING LIGHTS JUST MENTIONED. THE LIGHTS BEGAN TURNING ON AGAIN AND THE CAR WAS TAKEN BACK TO THE DEALER ON JUNE 20, 2005. THE LEFTWHEEL SENSOR, AND AN OXYGEN SENSOR WERE REPLACED, THIS, I WAS TOLD,WOULD FIX THE PROBLEM. ON JUNE 24TH THE CAR BEGAN MISS FIRING ON MY WAY TO WORK. THE PROBLEM WAS SO SEVERE THAT I HAD TO HAVE THE CAR TOWED TO ANOTHER DEALER. THIS DEALER'S TECHINCIAN INFORMED ME THAT THE FUEL PUMP WAS BAD, AND PROBABLY WAS ON THE 20TH, WHEN THE OTHER DEALER SERVICED IT. AND MORE UPSETTING TO ME, I WAS FURTHER INFORMED THAT THE WHEEL SENSOR DEALER #1 HAD REPLACED WAS STILL NOT WORKING PROPERLY. I NOW HAVE PAID NEARLY $1200.00 IN REPAIR COSTS, AND MY CAR IS STILL MISS FIRING, THE THREE LIGHTS I LISTED ABOVE ARE STILL ON, AND NOW THE CHECK ENGINE LIGHT IS ON TOO. THE CAR IS TOTALLY UNSAFE TO DRIVE. IT HAS JUST UNDER 50K MILES, I DRIVE CAREFULLY AND THE CAR HAS BEEN VERY WELL MAINTAINED. I TRUELY BELIEVE THERE IS A SERIOUS AND DANGEROUS DEFECT WITH THIS VEHICLE THAT GM'S TRAINED MECHANICS ARE UNABLE TO DIAGNOSE AND REPAIR. THIS, I WAS TOLD

ON JANUARY 28TH 2005, I TOOK MY 2003 CHEVY CAVALIER TO MY GM DEALERSHIP FOR SERVICE ON A RECALL ISSUED BY YOU AND GM, RECALL #04083. THIS RECALL IS ONE OF THE MOST BLATENT DISREGUARD FOR HUMAN LIFE. YOU GAVE CHEVY OPTIONS! OPTIONS, THAT SHOULDNT HAVE BEEN GIVEN BECAUSE WITH THESE OPTIONS HUMAN LIFE IS STILL AT RISK! THIS RECALL ALLOWS CHEVY TO APPLY GREASE BEFORE REPLACING THE REAR LAMP BULB SOCKETS, NOT JUST TO REPLACE THEM AND INSURE MY SAFTEY AS A COMSUMER. MY CAR WAS SERVICED ON JANUARY 28TH 2005 FOR THIS RECALL. GREASE WAS APPLIED AND WITH IN 3 DAYS MY PASSENGER SIDE REAR LAMP FAILED AND HAD DONE SO WITH ALL SIGNS LISTED ON THE RECALL. BUT BECAUSE THE DEALER HAD DONE THE RECALL THEY TRIED TO TELL ME IT WAS A BURNT OUT LIGHT BULB. WHICH IN THE END PROVED NOT TO BE. THE WHOLE SOCKET WAS THEN REPLACED ON JANUARY 31ST 2005. FAST FOWARD TO APRIL, MY WARRANTY HAS SINCE EXPIRED. WHEN MY DRIVERS SIDE REAR LAMP FAILS, ALSO WITH ALL THE SIGNS LISTED ON THE RECALL, BUT BECAUSE THE DEALER HAD DONE THE RECALL THEY TRIED TO TELL ME IT WAS A BURNT OUT LIGHT BULB. I CHECK THE LIGHTBULB, WHICH WAS FINE. I CALLED THE DEALERSHIP AND SPOKE WITH THE SERVICE MANAGER AND ADDRESSED THE SITUATION. WHY WERE BOTH THE SOCKETS NOT REPLACED AT THE TIME THE PASSENGER SIDE FAILED? THE ANSWER I RECEIVED MADE ME TAKE A STEP BACK. I WAS TOLD, CHEVY DOES NOT ALLOW THEM BOTH TO BE REPLACED UNLESS THEY ARE BOTH BROKEN OR IN THIS CASE HAVE FAILED. CHEVY WILL NOT REPLACE SOMETHING UNLESS IT IS BROKE.EVEN IF IT IS A SAFTEY RECALL! TO CLARIFY THE SITUATION I CONTACTED CHEVROLETS CUSTOMER SERVICE LINE AND RECEIVED THE SAME INFORMATION. THE DEALEARSHIP ENDED UP FIXING THE RECALL AT NO CHARGE TO ME, ON APRIL 30TH 2005. WHY WAS CHEVY GIVEN ANY OPTIONS? WHY WAS MY LIFE PUT ON THE LINE FOR A MERE $100.00, IF THAT? THIS RECALL NEEDS TO BE RECALLED ITSELF AND CHEVY NEEDS TO BE MADE TO REPLACE EACH AND EVERY REAR LIGHTBULB SOCKET ON EVERY CHEVY CAVALIER IT PRODUCED IN 2003.

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.
