I PURCHASED MY 2003 CAVALIER BRAND NEW WITH 106 MILES ON IT (IT HAD TO BE DRIVEN FROM PITTSBURGH TO HARRISBURG). IN LATE SEPT. OR EARLY OCT. MY CAR BEGAN RATTLING AT STOP LIGHTS. THE DAY AFTER THE RATTLING STARTED, MY CAR STALLED AT MY PLACE OF BUSINESS AND WOULDN'T START AGAIN. A TRIPLE A MECHANIC WAS CALLED AND COULDN'T DETERMINE WHAT THE PROBLEM WAS EXCEPT HE THOUGHT IT WAS THE FUEL PUMP. AFTER HAVING THE VEHICLE TOWED TO A GARAGE, I WAS TOLD THAT OIL WAS NOT MAKING ITS WAY THROUGH MY ENGINE CAUSING FRICTION AND IN TURN CAUSING MY ENGINE TO EXPAND BREAKING MY TIMING CHAIN AND BASICALLY RENDERING THE ENTIRE ENGINE USELESS. THE MECHANIC ASKED ME IF MY CHECK ENGINE LIGHT OR OIL LIGHT WAS LIT ON MY DASHBOARD BECAUSE WITH A PROBLEM WITH THE OIL PUMP, ONE OF THOSE LIGHTS WOULD HAVE LIT UP, WHICH I RESPONDED NO. HE THEN THOUGHT THAT THE DASHBOARD LIGHTS WERE NOT FUNCTIONING WHICH WAS NOT TRUE BECAUSE WHEN HE TURNED THE KEY, ALL THE DASHBOARD LIGHTS LIT UP. HE THEN WENT ON TO TELL ME THAT MY OIL LEVELS WERE NORMAL AND THAT MY TIMING CHAIN SHOULD LAST FOR 25+ YEARS. THE MECHANIC WENT ON TO EXPLAIN THAT I SHOULD CONTACT CHEVROLET BECAUSE HE BELIEVE THAT WITH THE LOW MILEAGE OF MY VEHICLE AND THE RELATIVE NEW-NESS OF THE VEHICLE, THE ONLY CAUSE FOR THIS ISSUE WOULD BE A DEFECT. I CONTACTED CHEVROLET VIA EMAIL AND WAS TOLD THAT I WOULD RECEIVE A RESPONSE IN NO MORE THAN 48 HOURS. AFTER HEARING NO RESPONSE, I FILED A COMPLAINT WITH THE BBB AND STILL HAVE NOT HEARD ANYTHING. *TR

MY 2003 CHEVY CAVALIER HAS BEEN EXPERIENCING INTERMITTENT STARTUP ISSUES AND OCCASIONAL "CHUGGING" WHILE DRIVING - SEEMED LIKE THE CAR WOULD LURCH AHEAD AT TIMES, HAS ALSO BRIEFLY STALLED AT LIGHTS. ON 10/11/08, THE CAR WOULD BRIEFLY TURN OVER AND START FOR LESS THAN A MINUTE, SHUT OFF, AND AFTERWARDS REFUSED TO START. HAD CAR TOWED FROM MY RESIDENCE TO MECHANIC SHOP WHO ALERTED ME THAT FUEL PRESSURE WAS LOW. FUEL ELECTRONICS WERE FUNCTIONING AS PER COMPUTER CHECK, TURNED OUT TO BE A BAD FUEL PUMP. CAR IS AT ~110,300 MILES. HAD SPARK PLUGS, FUEL FILTER, ENGINE BELT REPLACED IN MARCH & APRIL OF 2008. *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

THE COIL ASSEMBLY FAILED AND TWO CYLINDERS STOPPED FIRING. I ONLY DROVE THE CAR ABOUT ONE-MILE TO THE REPAIR SHOP AFTER THE FAILURE (WHICH HAPPENED SUDDENLY). THE COIL ASSEMBLY HAD TO BE REPLACED AT A COST OF ABOUT $400. AFTER IT WAS REPLACED, THE "CHECK ENGINE" LIGHT CAME ON AND THE REPAIR SHOP SAYS THAT THE ON-BOARD COMPUTER DIAGNOSTICS INDICATES THAT THE CATALYTIC CONVERTER HAS FAILED. THE CAR CANNOT HAVE ITS REGISTRATION RENEWED WITHOUT A FUNCTIONING CATALYTIC CONVERTER, WHICH WILL COST ABOUT $500 TO REPLACE. *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.
