WENT TO START CAR TO GO TO STORE AND IT WOULD NOT START. LUCKILY IT WAS AT HOME WHEN IT DECIDED TO STOP WORKING. TOWED TO GARAGE AND THEY SAID IT WAS THE FUEL PUMP. THE GARAGE REPLACED THE FUEL PUMP AND IT FIXED THE NO START ISSUE. I HAD NO IDEA THAT THIS WAS THE PROCESS TO START A RECALL INVESTIGATION OR I WOULD HAVE SAID LONG AGO. THERE HAS BEEN LOTS OF RECALLS LATELY ON GM AND THIS SAME CAVALIER DECIDED NOT TO START TWICE AFTER THE FUEL PUMP, ONCE IN 2011 WAS THE TIMING CHAIN THEN AGAIN DECEMBER 2012 THAT I STILL HAVE TO DIAGNOSE WHICH LED ME TO RESEARCH RECALLS. EACH TIME THE CAR STOPPED WORKING LUCKILY IT WAS IN MY DRIVEWAY EACH AND EVERY TIME. THE TIMING CHAIN THERE WAS SOME WARNING, IT WOULD SOMETIMES BUCK, OTHER TIMES IT WAS FUSSY ON STARTING AND IT WOULD STALL AT STOP LIGHTS. I WILL REPORT A NEW ISSUE IF I CAN FIND OUT THE 3RD UNKNOWN 2012 ISSUE. *TR

ENGINE STUMBLED ONCE AND THEN STALLED WHILE DRIVING DOWN SNOW- COVERED ROAD. HAD TO BE PUSHED OUT OF TRAFFIC. ENGINE WOULD NOT RESTART. WAS TOWED TO REPAIR FACILITY AND IN-TANK FUEL PUMP HAD FAILED. OWNER HAS ALWAYS BEEN CAREFUL TO MAINTAIN AT LEAST 1/4 TANK LEVEL AS THIS FAILURE HAS BEEN WIDELY PUBLICIZED. EARLIER MODEL 1993 CAVALIER WENT TWICE THIS MILEAGE WITHOUT ANY FUEL PUMP FAILURES. *TR

AT APPROX. 67K MY FUEL PUMP FAILED. I PURCHASED AND INSTALLED A NEW FUEL PUMP, ADHERING TO THE MANUFACTURERS INSTALLATION RECOMMENDATIONS. LESS THAN 6 MONTHS LATER THE NEW PUMP FAILED. THE HAS BEEN A RECURRING PROBLEM NOW FOR AT LEAST 10 FUEL PUMPS. THIS INSTALLATION RECOMMENDATIONS HAVE NOT CHANGED AND I HAVE HAD THE ELECTRICAL SYSTEM THAT POWERS THE PUMP CHECKED OUT AS WELL. IN EACH CONDITION IT WAS A NO START "FAILURE", LEAVING ME STRANDED IN EACH CASE AND COSTING ME HUNDREDS OF DOLLARS IN TOWING FEES THAT ARE NON-REFUNDABLE. EVEN THOUGH THE AUTO PARTS STORES HAVE BEEN KIND ENOUGH TO HONOR THE WARRANTY MOST TIMES I HAVE STILL HAD TO PAY FOR AT LEAST 5 OF THE 10 FUEL PUMPS. THAT'S A 1 TO 1 RATIO. I HAVE ALSO READ ABOUT THE CONDITION WITH BRUSHES IN THE MOTOR WEARING OUT. SOME OF THESE PUMPS HAVE PROVIDED 30K MILES OR MORE AND OTHERS NOT 3K MI. THIS IS A HUGE PROBLEM AND I FOR ONE WILL NOT BE SHOPPING FOR ANOTHER CHEVY UNTIL THIS PROBLEM ACKNOWLEDGED AND RESOLVED. I AM RESEARCHING MY PURCHASES/EXCHANGES TO VERIFY THE DATES AND WILL REGISTER EACH ONE OF THEM INDIVIDUALLY. *KB

MY CAR WOULD NOT START AFTER I TURNED IT OFF. I BANGED ON THE GAS TANK WITH A HAMMER, WHILE A COWORKER CRANKED THE ENGINE OVER AND THE FUEL PUMPED KICKED IN. THIS RESULTED IN THE CAR STARTING; HOWEVER I PLAYED IT SAFE AND HAD IT TOWED HOME. I REPLACED THE FUEL PUMP AND HAVE NOT HAD ANY PROBLEMS SINCE. STILL UNFORTUNATE THAT THE FUEL PUMP BARELY LASTED 100K. I BELIEVE CHEVY SHOULD GIVE YOU A FUEL PUMP FREE OF CHARGE IF THERE IS A FAILURE WITHIN THE FIRST 200K MILES. PLAIN AND SIMPLE FUEL PUMPS SHOULD NOT FAIL AS OFTEN AS THEY DO WITH THIS MAKE/MODEL. IT'S IS DANGEROUS TO EVERYONE'S HEALTH, AND I HOPE NO ONE EVER GETS HURT FROM IT. *TR

I DON'T KNOW WHAT TO DO ABOUT THIS. WE ARE ON A FIXED INCOME AND CAN'T AFFORD THIS RIGHT NOW. THERE WAS A RECALLED THE CARS FROM 1998 TO 2002 AND FIXED THE PROBLEM.

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.
