SPEEDOMETER STICKING AT 80 TO 160 MPH, EVEN THOUGH THE CAR HAS NEVER EVER BEEN DRIVEN AT THOSE SPEEDS, SPEEDOMETER REGISTARS ANWHERE FROM 10MPH TO OVER THE LIMIT OF THE SPEEDOMETER (180MPH) WHEN THE CAR IS SHUT OFF OR STOPPED. THIS STARTED AT 25,000 MILES ON THE ODOMETER. THE TEMPERATURE GAUGE STARTED REGISTERING OVER THE RED (AND HAS ACTUALLY TOUCHED THE SPEEDOMETER GAUGE NEEDLE) APPROXIMATELY 1 YEAR LATER STARTED AT 32,000 MILES. AT 39,000 THE GAS GAUGE STARTED DOING THE SAME THING. I HAVE BEEN DRIVING WITH A PORTABLE GARMIN NUVI GPS SINCE 2008, JUST TO USE THE ESTIMATED SPEED IN THE HOPES I WILL NOT GET A SPEEDING TICKET. THE FIRST TIME I LOOKED DOWN AND SAW MY SPEEDOMETER AT 85 MPH, I INSTINCTIVELY SLAMMED ON THE BRAKES, AND WAS EXTREMELY LUCKY NO ONE WAS BEHIND ME. I WAS ONLY GOING 50 MPH AT THE TIME THIS HAPPENED. I NOW HAVE A TEEN DRIVER, AND I CANNOT ALLOW HER TO DRIVE THIS CAR BECAUSE SHE IS NOT EXPERIENCED ENOUGH TO ESTIMATE HER SPEEDS. I WILL NEVER KNOW IF MY CAR TRULELY OVERHEATS BECAUSE IT OVERHEATS ON THE GAUGE 3-5 TIMES A WEEK. I HAVE TO FILL MY GAS BASED ON WHEN I FILLED IT LAST & HOW MANY MILES I HAVE DRIVEN SINCE AS I HAVE NO IDEA HOW MUCH GAS I HAVE. THIS CAN BE A VERY DANGEROUS SITUATION, THAT CAN LEAD TO DEATH AND INJURY, AS A TOLD YOU MY EXPERIENCE WITH INSTINCTIVELY SLAMMING ON THE BRAKES, AND I WOULD HATE TO SEE WHAT HAPPENS IF I RUN OUT OF GAS UNKNOWINGLY IN THE 3RD LANE OF AN EXPRESSWAY. I ALSO OWN A 2002 CHEVY CAVALIER WHOSE GAS GAUGE REGISTARS 1/4 OF A TANK WHEN IT IS EMPTY. I SPEND OVER $450 AT A GARAGE TO FIND OUT THAT THE CAR WAS NOT BREAKING DOWN, BUT WAS ACTUALLY RUNNING OUT OF GAS. THE 2003 CHEVY CAVALIER OF COURSE HAS THE MORE DANGEROUS PROBLEM WITH THE ENTIRE INSTRUMENT CLUSTER A MESS. UNFORTUNATELY, THE VECICLE WAS NOT STILL UNDER WARRANTY WITH THE LOW MILEAGE, AS IT HAD BEEN OVER 3 YEARS. WHEN ARE YOU GOING TO DO SOMETHING ABOUT THESE CARS? LETS HOPE I'M NOT DRIVING IN FRONT OF YOUR MOTHER OR DAUGHTER TOMORROW. *TT

SECOND EVER SINCE I BOUGHT MY CAR FOR NO REASON AT ALL IT WOULD JUST STALL AT REDLIGHTS WHEN I WOULD TAKE OFF, DEALER SAID NO PROBLEM, I HAVE NEARLY WRECKED MANY TIMES BECAUSE OF THIS, THE LATEST WAS TODAY I HAVE READ MANY FORUMS THAT SAY THEY FOUND OUT IT WAS THE FAULTY PLASTIC FUEL PUMP, WHY NO RECALL THIS IS GOING TO GET SOMEONE KILLED. *KB

ON MAY 31, MY 2003 CHEVROLET CAVALIER LS SPORT STALLED ON A HIGHWAY. I WAS IN HEAVY TRAFFIC AND MY POWER STEERING WENT OUT, BUT I WAS LUCKILY ABLE TO MAKE IT TO THE SIDE OF THE ROAD. I IMMEDIATELY EXITED MY VEHICLE AND CALLED ROADSIDE ASSISTANCE FOR A TOW. AFTER RECEIVING DIAGNOSTICS AT A CHEVY DEALERSHIP, IT WAS DETERMINED THAT MY FUEL PUMP HAD GONE OUT AND HAD TO BE REPLACED. THE COST OF THIS AND REPLACING A FUEL FILTER WAS CLOSE TO $1,000. MY CAR ONLY HAS 60,000 MILES ON IT, I HAD PREVIOUSLY REPLACED THE FUEL FILTER 1 YEAR BEFORE AT ANOTHER GM DEALERSHIP, AND I PERFORMED REGULAR MAINTENANCE ON THE VEHICLE IN ACCORDANCE WITH THE USER MANUAL. WHEN I WENT HOME I RESEARCHED THE ISSUE WITH THE CAR, AND LO AND BEHOLD I CAME ACROSS HUNDREDS OF PAGES WHICH DESCRIBED THE EXACT SAME PROBLEM I HAD. ON ONE FORUM ALONE, THERE WERE OVER 700 POSTS WHERE OWNERS OF THE 2003 MODEL CAVALIER HAD FUEL PUMPS GO OUT AT AROUND THE SAME MILEAGE AS MY CAR, WITH REPAIR COSTS RANGING FROM $300-$900. I CONTINUED TO RESEARCH THE ISSUE, AND FOUND THAT THE NHTSA HAD RESEARCHED A LARGE NUMBER OF CONSUMER COMPLAINTS REGARDING FUEL PUMP FAILURES WITH THE 2003 MODEL CAVALIER ' INVESTIGATION #EA07015 AND #PE07033. GM DOCUMENTS IN BOTH OF THESE CASES INDICATED A LARGE NUMBER OF MALFUNCTIONS IN MODELS UP TO 2003, THEN A SHARP DECREASE IN FAILURES IN THE 2004 MODEL. *TR

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.
