I WAS DRIVING MY CAR TO GO GET GROCERIES WITH MY 2 YR OLD SON. THE CAR HAS NO PROBLEMS AND DROVE FINE THERE. I ATTEMPTED TO PULL OUT OF THE PARKING LOT AND MY CAR STALLED. I TRIED AGAIN AND IT STALLED ONCE MORE. I MANAGED TO TURN THE ENGINE OVER ENOUGH TIMES TO GET IT OUT OF THE MIDDLE OF THE PARKING LOT. IT WAS AROUND 8PM AND GETTING COLD AND I HAD NOT ONLY TO DEAL WITH THIS, BUT HAVE A YOUNG CHILD OUT IN THE COLD WHETHER WHEN HE SHOULD BE GOING TO BED. I CALLED MY BOYFRIEND AND HE PICKED US UP AND HE LOOKED AT THE CAR A BIT SINCE HE KNOWS QUITE A BIT ABOUT CARS. HE COULD NOT FIND ANYTHING OBVIOUS SO WE HAD IT TOWED FOR TESTING TO MECHANIC HE KNOWS. THE MECHANIC WAS GENEROUS ENOUGH TO GIVE US A BIT OF A DISCOUNT ON THE TOW AND FUEL PUMP, BUT GETTING THIS REPAIRED WAS STILL COSTLY. I ENDED UP PAYING HALF AND MY BOYFRIEND WAS GENEROUS ENOUGH TO HELP ME PAY FOR THE OTHER HALF. BEING A SINGLE MOM AND STILL FINISHING UP SCHOOL I DID NOT HAVE THE MONEY AT THE TIME TO REPLACE SOMETHING THAT GAVE ME NO WARNING AND SHOULD HAVE BEEN RECALLED IN THE FIRST PLACE. I'M GLAD THIS DIDN'T HAPPEN ON THE INTERSTATE WITH MY SON. PEOPLE COUPLE HAVE GOTTEN HURT IF WE WERE IN AN ACCIDENT. GM NEEDS TO REALIZE HOW BIG OF AN ISSUE THIS IS. *TR

WHILE DRIVING ON A 4 LANE HIGHWAY, I STOPPED A TO MAKE A LEFT HAND TURN ACROSS THIS BUSY HIGHWAY, UPON MY TURN THE CAR LOST POWER AND STALLED IN THE MIDDLE OF THE ON COMING LANES OF TRAFFIC. RESTARTED THE VEHICLE AND CONTINUED TO STALL MOVING ONLY A FEW FEET AT A TIME AND WOULD NOT RESTART, BEING THAT I AM DISABLED THIS CAUSED A DANGER TO MYSELF AND OTHERS ON THIS BUSY HIGHWAY (AKA) HIGHWAY OF DEATH IN THIS AREA. IN CALIFORNIA HWY 99/70 NORTH BOUND NORTH OF SACRAMENTO CA. AFTER A TIME SOME MOTORIST ASSISTED ME AND PUSHED MY VEHICLE OUT OF LANES OF TRAFFIC TO THE EDGE OF THE HIGHWAY. I HAD NO WARNING OR INDICATION THAT THE VEHICLE WAS ABOUT TO FAIL OR THAT ANY SYSTEM NEEDED ATTENTION. BECAUSE OF MY DISABILITIES, I WOULD NEVER DRIVE A VEHICLE THAT WAS NOT RELIABLE OR WOULD CAUSED A SITUATION TO ARISE THAT WOULD BE A DANGER TO MYSELF AND THE MOTORING PUBLIC. A MECHANIC AT A CHEVROLET DEALER THAT I HAVE KNOWN FOR YEARS ADVISED ME THE BEWARE OF FUEL PUMPS IN THESE VEHICLES AS THEY HAVE A VERY HIGH RATE OF FAILURE. I ALSO ASKED THE MECHANIC IF KNEW WHAT I COULD DO TO AVOID THIS SITUATION AND HE STATED THAT NO OFFICIAL MANUFACTURE ADVISORY WERE AVAIL. IN HIS OPINION THE FUEL PUMPS OF POOR QUALITY AND SUFFERED FROM OVER HEATING BEING THEY A COOLED BY THE GASOLINE IN THE TANK. AND SUGGESTED TO KEEP THE TANK FULL. I NEVER LET THE FUEL GET BELOW 1/4 TANK LEVEL AND USUALLY REFILL AT 1/2. THIS IS A 2003 MODEL WITH 39,593 MILES THE VEHICLE WAS TOWED TO MY HOME. NOT REPAIRED. I AM NOT SURE IF I SHOULD HAVE IT REPAIRED. I HAVE NO FAITH IN THE DEALERSHIP OR THE MANUFACTURE AND THE ONLY OTHER CHOICE IS TO JUST SELL IT TO ANOTHER PERSON ADVISING THEM BEFORE HAND OR SELLING TO A WHOLESALE DEALER. I AM DRIVING MY OTHER VEHICLE. *TR
SHUT CAR OFF AND WOULD NOT START AGAIN 2003 CHEVROLET CAVALIER FUEL PUMP FAILURE. *JB
Official recalls
104V524000 · Exterior Lighting:turn Signal
Nov 1, 2004
ON CERTAIN PASSENGER VEHICLES, THE REAR LAMPS THAT PROVIDE STOP AND TURN SIGNALS AND TAIL LAMP FUNCTIONS STOP WORKING BECAUSE OF INADEQUATE CONTACT BETWEEN THE BULB AND SOCKET. IN ADDITION, IF ONE BULBS WERE TO BECOME INOPERATIVE WHILE THE VEHICLE WAS OPERATING IN CRUISE CONTROL, THE CRUISE CONTROL WOULD DISENGAGE WHEN THE REMAINING BULB WAS ACTIVATED. IF BOTH LAMPS WERE TO BECOME INOPERATIVE, THE CRUISE CONTROL WOULD NOT ENGAGE.
Consequence & remedy
Consequence: AN INOPERATIVE BRAKE LAMP WILL NOT CONVEY THE DRIVER'S INTENTION OF STOPPING TO DRIVERS IN FOLLOWING VEHICLES, AND AN INOPERATIVE REAR TURN SIGNAL LAMP WILL NOT CONVEY THE DRIVER'S INTENTION TO TURN TO DRIVERS IN FOLLOWING VEHICLES. BOTH OF THESE FAILURES CAN INCREASE THE RISK OF A CRASH.
Remedy: DEALERS WILL INSPECT THE REAR LAMP BULB SOCKET ASSEMBLIES AND APPLY GREASE OR REPLACE THEM IF NECESSARY. THE RECALL BEGAN ON JANUARY 18, 2005. OWNERS SHOULD CONTACT CHEVROLET AT 1-800-630-2438 OR PONTIAC AT 1-800-620-7668.

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.
