I WAS RETURNING HOME AND WHEN I PULLED INTO MY DRIVEWAY MY CAR HAD AN EXTREME LOSS OF POWER. I WAS SURPRISED BY THIS BECAUSE IT WAS A SUDDEN CHANGE IN MY CARS PERFORMANCE. I HAD NOT BEEN HAVING ANY TROUBLE BEFORE THIS. AFTER I PARKED MY CAR AND TURNED IT OFF I LATER ATTEMPTED TO LEAVE. IT WOULD NOT START. THE ENGINE AND EVERYTHING TURNED OVER FINE IT JUST DID NOT SEEM TO BE GETTING FUEL. I THEN TURNED THE KEY ON AND OFF AND REALIZED THAT THE FUEL PUMP WAS NOT RUNNING. I RESEARCHED ONLINE AND FOUND THIS TO BE A VERY COMMON ISSUE WITH THE 2003 CAVALIERS. THANKFULLY I WAS IN MY DRIVEWAY WHEN THIS HAPPENED AND NOT IN THE LEFT LANE OF THE FREEWAY IN RUSH HOUR. I WILL BE SPENDING MY WEEKEND REPLACING MY FUEL PUMP. I WILL KEEP THE DEAD PUMP IF IT IS NEEDED FOR INVESTIGATION. *TR

THE FUEL GAUGE BEGAN TO MALFUNCTION ABOUT A YEAR AGO. ASSUMING IT WAS JUST THE FLOAT, I DECIDED I WOULD IGNORE IT AND USE THE TRIP ODOMETER TO DETERMINE HOW MUCH GAS I HAD LEFT. UNFORTUNATELY, BECAUSE THE GAS GAUGE WENT WELL PAST FULL, INTO THE REALM OF WHAT WOULD BE CONSIDERED TWO TANKS OF FULL, THE TEMPERATURE GAUGE NEEDLE COULD NOT MOVE. EVENTUALLY, THE GAS GAUGE NEEDLE WENT PAST THE TEMPERATURE GAUGE (NOW AT WHAT WOULD BE CONSIDERED TWO AND A HALF TANKS) WHICH FREED THE TEMPERATURE NEEDLE TO ACTUALLY REGISTER. NOW, THE TEMPERATURE GAUGE IS MALFUNCTIONING, RESTING AT THE HALF WAY POINT EVEN AFTER THE CAR SAT ALL NIGHT IN OUR RECENT FRIGID TEMPERATURES. IT NOW RUNS IN THE RED EVEN THOUGH THERE IS NOTHING WRONG WITH THE ENGINE. NOW, THE SPEEDOMETER IS SHOWING SIGNS OF MALFUNCTIONING, AS IT READS 5 MPH THOUGH I AM AT A COMPLETE STOP. RESEARCH ON VARIOUS INTERNET MESSAGE BOARDS SUGGEST THIS IS A VERY COMMON PROBLEM IN NOT ONLY 2003 CHEVROLET CAVALIERS, BUT OTHER YEARS AND MODELS OF CHEVY VEHICLES. WHEN I COMPLAINED TO GM THAT A MALFUNCTIONING SPEEDOMETER WAS A SAFETY ISSUE, I WAS GREETED WITH "THERE'S NO RECALL, IT'S NO LONGER UNDER WARRANTY, CAN'T HELP, YOUR PROBLEM, DEAL WITH IT." FOLLOWING THIS LOGIC, WHAT'S STOPPING GM FROM CREATING MORE DEFECTIVE VEHICLES, IF THE PROBLEM HAPPENS AFTER THE WARRANTY EXPIRES? THEY'VE ADOPTED THE ATTITUDE IT'S "NOT THEIR PROBLEM." AT WHAT POINT IS A DEFECTIVE SPEEDOMETER NOT A SAFETY PROBLEM WORTHY OF A RECALL? *TR

TAPPING ON BOTTOM OF FUEL TANK WHILE TRYING TO START CAR RESULTED IN CAR STARTING. DIAGNOSIS: NEW FUEL PUMP REQUIRED. ANTICIPATED COST $250 + LABOR. TOTAL ANTICIPATED COST: $450 + LABOR. FORTUNATELY NO OR LITTLE TRAFFIC. ALSO FORTUNATE TOW TRUCK RESPONDED QUICKLY OTHERWISE PERSONAL INJURY FROM COLD COULD HAVE OCCURRED. THIS SHOULD NOT HAVE HAPPENED AT THIS LOW MILEAGE. FUEL PUMPS SHOULD BE LIFETIME ENGINEERED. *TR

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.
