WHEN I PURCHASED MY USED 2000 CHEVROLET CAVALIER IN APRIL 2003 ABOUT 1 MONTH I STARTED HAVING PROBLEMS. AFTER PUTTING GAS IN MY CAR I WOULD DRIVE A LITTLE AND THEN THE GAS GAUGE WOULD GO DOWN TO APPEAR THAT THE CAR WAS ALMOST EMPTY BUT IT WASN'T. WHILE DRIVING ONE DAY THE CAR JUST SHUT OFF IT HAD GAS IN IT I HAD JUST PUT GAS IN IT BUT THE GAUGE DROPPED TO APPEAR TO BE ALMOST EMPTY. I HAD TO GET MY CAR TOWED TO THE SHOP I WAS TOLD MY FUEL INJECTION WENT OUT. NOT EVEN A MONTH AFTER THAT MY CAR STALLED AT A RED LIGHT AND MY TEMPERATURE GAGE WENT IN THE HOT ZONE MY CAR WOULDN'T START I HAD TO GET IT TOWED AGAIN TO THE SHOP BUT THEY COULD NOT FIND THE PROBLEM. NOW HERE IT IS JUNE 2003 MY CAR IS SITTING IN THE DRIVE WAY RIGHT NOW AS I AM TYPING THIS INFORMATION. MY SON WAS DRIVING HOME AT 1:00 A.M. THIS MORNING FROM WORK WHEN THE CAR OVERHEATED AGAIN AND STARTED SMOKING. HE SAID SMOKE WAS ALSO COMING OUT OF THE BATTERY AND HE ALSO HEARD NOISE COMING FROM THE REAR OF THE CAR TODAY IS SATURDAY AND MY CAR HAS TO SIT IN THE DRIVEWAY UNTIL MONDAY MORNING THAT WHEN THE DEALER OPENS. I FEEL THAT SOMETHING SHOULD BE DONE. I DON'T THINK IT IS FAIR FOR DEALERS TO BE ABLE TO SALE CARS THAT ARE IN THIS KIND OF CONDITION AND THE CAR IS SUPPOSE TO BE CERTIFIED. I AM MAKING PAYMENTS ON THE CAR AND I AM HAVING ALL THESE PROBLEMS. IT IS DANGEROUS TO BE DRIVING AND THE CAR DECIDES TO CUT OFF ESPECIALLY AT 1:00 A.M. I HAVE TO BE AT WORK AT 3:45 A.M. AND MY SON GETS OFF WORK AT 1:00 A.M. THIS IS VERY, VERY DANGEROUS FOR THE BOTH OF US. *NLM

HEAD GASKET BLEW AT ONLY 50320 MILES, ALLOWING ANTIFREEZE TO ENTER THE ENGINE BLOCK AND FLOOD CYLINDER HEADS AND SPARK PLUGS, WARPING THEM TO THE POINT WHERE THEY HAD TO BE REBUILT, IN ADDITION DUE TO LACK OF ANTIFREEZE, CAR OVERHEATED ALMOST TO THE POINT OF CATCHING FIRE, SEIZING THE ENGINE. THIS CAME WITH NO WARNING, AND NO SIGN OF LEAKAGE AS ANTIFREEZE LEAKED INTO ENGINE RATHER THAN ONTO GROUND. CAR BROKE DOWN IN THE MIDDLE LANE OF A BUSY INTERSECTION WHILE STOPPED AT A LIGHT CAUSING A TRAFFIC OBSTACLE DURING MORNING RUSH HOUR. *NLM

TIMING CHAIN LOOSE/TENSIONER WEARING OUT. FIRST HAPPENED AROUND 60,000 MILES, AT THIS TIME THE CHAIN, TENSIONER, AND GEARS WERE CHANGED. WORKED FINE FOR A WEEK AND A HALF, THEN SLOWLY STARTED TO RATTLE AGAIN UNTIL THE NOISE WAS WORSE THAN BEFORE IT WAS FIXED. BROUGHT TO CHEVY DEALERSHIP, CAR STAYED THERE FOR 5 DAYS, SAID THEY COULDN'T FIND ANYTHING WRONG, CHARGED ME $250 FOR DIAGNOSTIC LABOR AND TOLD ME IT WAS A NORMAL NOISE. THEN I CALLED GM CUSTOMER SERVICE, THE WOMAN I SPOKE TO WAS ALL READY TO HELP ME OUT UNTIL SHE SPOKE WITH THE DEALERSHIP THEN CAME BACK ON THE LINE WITH ME AND JUST AGREED WITH WHAT THEY SAID ABOUT IT BEING A "NORMAL" NOISE. THEN BROUGHT IT TO ANOTHER CHEVY DEALERSHIP, SERVICE MANAGER LISTENED AND SAID IT WAS DEFINITELY NOT A NORMAL NOISE, AGREED IT WAS COMING FROM THE TIMING COVER AREA, CALLED BACK CUSTOMER SERVICE, SAID I'D HAVE TO PAY FOR ANOTHER DIAGNOSIS BEFORE THEY COULD EVEN TELL ME IF THEY WOULD ASSIST ME IN GETTING IT FIXED. I'M FINISHED WITH IT, I'VE SPENT OVER $1000 ON THIS CAR IN THE LAST 2 MONTHS AND IT'S STILL NOT FIXED, PLUS I'M OUT $250 FOR A DEALERSHIP TELLING ME THERE'S NOTHING WRONG. THIS DEALERSHIP WAS NOT THE ONE I PURCHASED THE CAR FROM.....THE ORIGINAL DEALER MESSED UP MY ROTORS AT 10,000 MILES AND WERE VERY RUDE ABOUT IT SO I VOWED NEVER TO GO THERE AGAIN.....NOW I'VE BEEN BURNED BY TWO DEALERSHIPS...

204V036000 · Electrical System:ignition:switch
Jan 27, 2004
ON CERTAIN PASSENGER VEHICLES. IF THE ENGINE FAILS TO START AND THE DRIVER HOLDS THE KEY IN THE "START" POSITION FOR AN EXTENDED PERIOD, HIGH CURRENT FLOWS THROUGH THE IGNITION SWITCH, AND SOMETIMES PRODUCES ENOUGH HEAT TO MELT INTERNAL SWITCH PARTS.
Consequence & remedy
Consequence: IF THE SWITCH IS DAMAGED, A FIRE COULD OCCUR IN THE STEERING COLUMN, EVEN WITH THE ENGINE OFF AND THE KEY REMOVED. THE FIRE COULD SPREAD TO THE INTERIOR OF THE CAR, WHICH COULD INJURE OCCUPANTS OR CAUSE DAMAGE TO ADJOINING STRUCTURES.
Remedy: DEALERS WILL INSTALL A RELAY KIT IN THESE VEHICLES TO PREVENT HIGH CURRENT FROM FLOWING THROUGH THE IGNITION SWITCH, AND CHECK THAT YOUR CAR WILL START WITH A PROPERLY CHARGED BATTERY AND, IF NECESSARY, REPLACE THE IGNITION SWITCH. OWNER NOTIFICATION WILL BEGIN ON MARCH 1, 2004. OWNERS WHO TAKE THEIR VEHICLES TO AN AUTHORIZED DEALER ON AN AGREED UPON SERVICE DATE AND DO NOT RECEIVE THE FREE REMEDY WITHIN A REASONABLE TIME SHOULD CONTACT CHEVROLET AT 1-800-630-2438, PONTIAC AT 1-800-620-7668, BUICK AT 1-866-608-8080, OR OLDSMOBILE AT 1-800-630-6537. CUSTOMERS CAN ALSO CHECK THEIR VEHICLE ONLINE BY GOING TO WWW.MYGMLINK.COM AND ENTERING THE VEHICLE'S IDENTIFICATION NUMBER.
00V201000 · Interior Lighting
Jul 20, 2000
VEHICLE DESCRIPTION: PASSENGER VEHICLES EQUIPPED WITH THE BI-FUEL OPTION FAIL TO COMPLY WITH FMVSS NO. 101, "CONTROL LOCATION, IDENTIFICATION, AND ILLUMINATION." THE INSTRUMENT PANEL LIGHTS IN THESE VEHICLES ARE AT FULL ILLUMINATION LEVELS AND CANNOT BE ADJUSTED. THE STANDARD REQUIRES AT LEAST TWO LEVELS OF ILLUMINATION.
Consequence & remedy
Consequence: THIS COULD MAKE IT MORE DIFFICULT TO SEE OBJECTS OUTSIDE THE VEHICLE WHEN DRIVING AT NIGHT.
Remedy: DEALERS WILL REPLACE THE FUEL TYPE INDICATOR SWITCH ASSEMBLY, WHICH INCLUDES THE INSTRUMENT PANEL ILLUMINATION CONTROL.
