THERE WAS A NOISE COMING FROM THE FRONT OF THE VEHICLE, THE DEALER LUBED THE FRONT SWAY BAR BUSHING. THE TIRES WERE OVER INFLATED, SO THE VEHICLE WOULD SWAY WHEN GOING OVER BUMPS, THE BLOWER MOTOR, AND HEATER CONTROL WAS REPLACED. THE ABS LAMP ILLUMINATED. THE VEHICLE NEEDED BRAKE PADS. THERE WAS MOLD ON THE DRIVERS FRONT DOOR. THE AC COMPRESSOR WAS REPLACED. THE WINDOW WENT DOWN EXTREMELY SLOW, THE DEALER LUBED THE WINDOW TRACK AND REGULATOR. THE FOG LIGHT BULB WAS INOPERATIVE, THE DOOR LATCH WAS INOPERATIVE. *JB

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.

I BOUGHT MY 2003 CAVALIER IN FEB. 2003. WITHIN MONTHS OF PURCHASE I BEGAN TO HAVE PROBLEMS WITH MY TAIL LIGHTS. MY LEFT TAIL LIGHT BURNT OUT COMPLETELY (BOTH TURN SIGNAL AND BRAKE LIGHT). IT WAS BROUGHT INTO THE DEALERSHIP IN WHICH THEY REPLACED THE SOCKET, BULB AND GREASED THE SOCKET. IN THE FOLLOWING MONTHS, MY LEFT TAIL LIGHT CONTINUED TO FAIL. TWO OF THOSE TIMES I WAS PULLED OVER BY THE LOCAL POLICE. ALSO DURING THE SUMMER OF 2003, MY BATTERY DIED, ALTHOUGH NO LIGHTS WERE LEFT ON; MY CAR STALLED WHILE IN DRIVE WAITING AT A STOP LIGHT; MY WINDOW MOTORS DIED AND HAD TO BE REPLACED; MY LOCKS FAILED TO WORK PROPERLY WHICH ALSO HAD TO BE REPLACED. THIS PAST YEAR I'VE HAD EVEN MORE PROBLEMS. AS OF RECENTLY, BOTH LEFT AND RIGHT TAIL LIGHTS FAILED, AND BOTH WERE REPLACED, AND THE RIGHT ONE WENT OUT YET AGAIN. THE TRUNK WAS LEAKING, WHICH CAUSED MOLD TO GROW IN MY TRUNK AND DAMAGING PERSONAL EFFECTS, AND ALSO CAUSING THE RIGHT SOCKET AND WIRES TO BECOME CORRODED. THE SOCKET AND WIRES WERE REPLACED AGAIN, AND THE LEAK WAS FIXED, BUT DEALER REFUSED TO REPLACED FABRIC IN TRUNK. DRIVER'S SIDE WINDOW MOTOR DIED YET AGAIN, AND WAS REPLACED. CD PLAYER STOPPED WORKING. DEALERSHIP ORDERED AND INSTALLED NEW SYSTEM. CURRENTLY I HAVE PROBLEMS WITH MY POWER STEERING UPON IGNITION WHEN COLD OUTSIDE, SQUEAKING SOUNDS OVER FRONT TIRES WHILE GOING OVER BUMPS AND TURNING, AND ALL AIR VENTS, EXCEPT PASSENGER SIDE ARE NOT FUNCTIONING PROPERLY. DEALERSHIP LOOKED AT VENTS BUT STATED THAT THEY WERE "OPERATING AS DESIGNED." OVER THE PAST 2 YEARS, MY "NEW" CAR HAS BEEN BACK TO THE DEALERSHIP ABOUT 15 TIMES. WAY TO GO GM...ANOTHER WINNER!
WHILE DRIVING APPROXIMATELY EVERY TWO MONTHS THE BRAKE LIGHT WILL ILLUMINATE THE DASH BOARD. THE FUEL PUMP BLEW OUT. THE HEATING A COOLING WENT BAD. THE VEHICLE MAKES NOISE WHEN MAKING RIGHT TURNS. CONSUMER HAS NOT FOUND OUT WHAT IT IS AS OF YET. THE VEHICLE HAS BEEN INTO THE DEALER AT LEAST TWENTY TIMES. *NM
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.

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.
