I WAS HEADING OUT OF MY HOUSE IN THE EVENING AND GOT ABOUT 2 OR 3 MILES FROM MY HOME WHEN I WENT TO MAKE A LEFT TURN THROUGH AN INTERSECTION. MIDDLE OF THE INTERSECTION MY VEHICLE STARTED TO SPUTTER AND WOULD NOT ACCELERATE WHEN I APPLIED PRESSURE TO GAS PEDAL. I WAS ONLY ABLE TO COAST JUST ENOUGH TO CLEAR THE INTERSECTION AND MY VEHICLE ENDED UP SHUTTING DOWN IN THE MIDDLE OF THE ROAD. THIS PROBLEM OCCURRED WITH OUT WARNING, NO SIGNS, NO LIGHTS MY VEHICLE JUST GAVE OUT ON ME IN THE MIDDLE OF AN INTERSECTION HAD IT OCCURRED JUST 5 SECONDS BEFORE I CLEARED THE INTERSECTION I MAY HAVE BEEN SERIOUSLY INJURED OR WORST IT COULD HAVE BEEN A FATAL ACCIDENT. I DO KNOW THAT THERE ARE PLENTY OF 2003 CHEVY CAVALIER OWNERS WHO HAVE EXPERIENCED THIS SAME PROBLEM AND IT NEEDS TO BE ADDRESSED. CARCOMPLAINTS.COM AND OTHER CONSUMER REVIEW SITES GIVE DETAILED SCENARIOS OF THIS DANGEROUS FUEL PUMP FAILURE AND ITS ABRUPT OCCURRENCE. THIS PROBLEM HAS OCCURRED AT MILEAGE AS LOW AS 7,000 AND WORKS ITS WAY UP. I WOULD LIKE TO BE SPOKEN WITH PERSONALLY BY SOMEONE ON THE BOARD AND FOR REASONS WHY THIS PROBLEM DOESN'T SEEM TO BE AN IMPORTANT SAFETY ISSUE.

NEXT WAS THE POPPING IN THE FRONT END, DEALERSHIP TURNED ROTORS, UNDER WARRANTY BACK BRAKES SQUEALED REAL LOUD THEY SAID IT WAS DUST I HAD TO PAY FOR THAT. BACK BRAKES STILL SQUEAL, FRONT END STILL POPS LIKE A BAD CV JOINT. TRUNK WOULDN'T SHUT HAD TO KEEP SLAMMING IT. TOOK IT BACK THEY GREASED IT WORKED FOR AWHILE STARTING TO GET HARD TO SHUT SOMETIMES. BRAKE LIGHTS AND BACK LIGHTS AND CRUISE CONTROL QUIT WORKING . TOOK IT TO DEALERSHIP AT LEAST 5 OR 6 TIMES TILL THEY FINALLY REPLACED IT HOW LONG IT WILL LAST I DON'T KNOW. FRONT SUN VISOR POPPED WHEN IT HUNG UP IN REAR VIEW MIRROR REAL FLOPPY CAN'T USE IT NO MORE DEALER SAID THEY ORDERED IT IN DECEMBER. STILL WAITING NOT FIXED. REAL BAD ODOR OF GAS IN CAR WHEN TANK IS HALF FULL, NO EXPLANATION AS TO WHY. SEAT BELT MAKES A FUNNY NOISE WHEN YOU ARE WEARING IT, PINS YOU BACK AGAINST SEAT REAL HARD. NO EXPLANATION FOR THAT. HAVE TO STOP AND JERK ON IT TO LOOSEN IT LIKE A SEAT BELT SHOULD WORK. DEALER SAYS I AM IMAGINING THIS STUFF BECAUSE I DO NOT WANT CAR, BOUGHT IT NEW STILL PAYING FOR IT. BEEN TRYING TO GET RID OF IT THEY HAVE EVERYONE CONVINCED I AM A PSYCHO WOMAN WANTING AN SUV AND THATS WHY I AM COMPLAINING THAT IS ALL FALSE. JUST PLAIN HATE A CAR I AM PAYING FOR.*AK

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.
