WHILE DRIVING ON THE HIGHWAY, I LOOKED AT MY SPEEDOMETER AND IT WAS NOT MOVING ABOVE 35 MILES PER HOUR. I PULLED OVER AND SAW THAT THE SPEEDOMETER DID NOT GO TO ZERO; IT STAYED AT 35 MILES PER HOUR.

WHILE DRIVING ON THE HIGHWAY, I LOOKED AT MY SPEEDOMETER AND IT WAS NOT MOVING ABOVE 35 MILES PER HOUR. I PULLED OVER AND SAW THAT THE SPEEDOMETER DID NOT GO TO ZERO; IT STAYED AT 35 MILES PER HOUR. I TURNED MY CAR OFF AND ON, AND THE SPEEDOMETER DECREASED TO 30 MILES PER HOUR. AFTER TURNING MY CAR OFF AND ON SIX TO SEVEN MORE TIMES, THE SPEEDOMETER FINALLY WENT BACK TO ZERO. AFTER THAT, I BEGAN DRIVING AGAIN. THE SPEEDOMETER WORKED FINE. THE NEXT DAY, THE SPEEDOMETER GOT STUCK AT 50 MILES PER HOUR. WITHOUT PULLING OVER AND TURNING THE CAR OFF, THE SPEEDOMETER BEGAN WORKING AGAIN, HOWEVER, IT SHOWED I WAS DRIVING AT 100 MILES PER HOUR, WHEN I WAS DRIVING WITH HIGHWAY TRAFFIC AT ABOUT 50-55 MILES PER HOUR. THIS HAPPENS JUST ABOUT EVERY DAY DURING THE SUMMER MONTHS. WHEN IT IS COLD, THIS TENDS TO HAPPEN LESS FREQUENTLY, MAYBE ONCE A MONTH. THE CAR HAS BEEN TAKEN TO TWO OR THREE MECHANICS AND EACH TIME I AM TOLD THAT THERE ARE NO PROBLEMS. THE COMPUTER SAYS THERE ARE NO PROBLEMS WITH THE CAR. THIS PROBLEM, WHEN FIRST NOTICED, COULD HAVE CREATED A SERIOUS HAZARD IF THE SPEEDOMETER WAS STUCK AT 55 MILES PER HOUR, AND THE DRIVER EXITED TO A CITY ROAD AT 30 MILES PER HOUR. THE DRIVER WOULD HIT THEIR BRAKES, THINKING THEY WERE DRIVING FAST, POSSIBLY CAUSING A COLLISION. WHEN THE SPEEDOMETER IS NOT WORKING THERE IS NO REAL WAY TO TELL THE EXACT SPEED THAT YOU ARE DRIVING. GENERAL MOTORS WAS CALLED THE DAY OF THE PROBLEM AND A REPORT REGARDING THE PROBLEM WAS CREATED. *TR

THE FUEL PUMP FAILED ON MY 2003 CHEVY CAVALIER LEAVING MY CAR POWER LESS (OFF) AT 65 MPH. THEN WOULD NOT START, LEAVING ME STRANDED ON A BUSY HIGHWAY. I AM HAVING TO BUY A NEW FUEL PUMP COSTING AROUND $200 AND TAKE TIME OFF OF WORK TO FIX IT.

I BOUGHT MY 2003 CAVALIER BRAND NEW. WHILE IT WAS STILL UNDER WARRANTY I TOOK THE CAR IN BECAUSE IT WAS MALFUNCTIONING. THE SITUATION WAS I WAS DRIVING ON THE HIGHWAY AND WENT TO SHIFT GEARS AND WHEN I HELD THE CLUTCH IN THE RPM'S DROPPED ALL THE WAY TO 0 AND THE CAR STALLED. WHEN I TOOK THE CAR IN I WAS TOLD THEY COULD NOT DUPLICATE THE ISSUE, SO THERE WAS NO PROBLEM. SINCE THAN THIS HAS ONLY GOTTEN WORSE. WHILE DRIVING IT STALLS ON AVERAGE OF 5 TIMES A WEEK WHICH IS NOT SAFE ESPECIALLY ON THE FREE WAY. ALSO TO ADD TO EVERYONE ELSE'S COMPLAINT MY FUEL PUMP WENT BAD AS WELL AND HAD TO HAVE IT REPLACED. *TR

I WAS ABLE TO STOP AT THE BEGINNING OF A LEFT TURN LANE AND PUT MY HAZARDS ON. WITH THE HELP OF MY PASSENGER AND A POLICE OFFICER, WE MOVED THE CAR ACROSS 2 LANES OF TRAVEL TO THE SHOULDER. THE CAR HAD 116,000 MILES AT THE TIME OF THE INCIDENT. THE ONLY WARNING BEFORE THE CAR LOST ALL POWER AND DRIVE-ABILITY WAS THE BATTERY LIGHT TURNING ON BRIEFLY. *TR

MY DRIVER'S SIDE POWER WINDOW WILL INITIALLY GO DOWN. WHEN I ATTEMPT TO POWER THE WINDOW UP, IT GOES APPROXIMATELY ONE TO TWO INCHES THEN STOPS. I HAVE TO CONTINUE DRIVING OR LEAVE MY CAR RUNNING UNTIL THE WINDOW IS UP. IT IS VERY UNSAFE TO LEAVE MY CAR IN ANY LOT OR PARKING SPACE WITH THE WINDOW DOWN. ON AVERAGE EVERY 10 MINUTES IT WILL GO UP ANOTHER INCH OR TWO. THIS HAPPENS EVERY TIME I POWER THE WINDOW DOWN. I WILL NOT LEAVE MY WINDOW DOWN. ELEMENTS WILL DAMAGE THE INTERIOR, AND IT LEAVES ME SUSCEPTIBLE TO VANDALS. I HAVE TWO CHILDREN AND I CONSIDER THIS MALFUNCTION UNSAFE FOR ME THE DRIVER AND MY CHILDREN. I PAID $18,000 FOR THE VEHICLE, I WILL NOT ALLOW THIS TO GO UNFIXED, HOWEVER I FEEL IT IS THE COMPANY'S RESPONSIBILITY TO RECALL AND REPAIR THE ISSUE. *TR

I OWN A 2003 CHEVROLET CAVALIER LS AND ON DEC. 25 WHEN I TURNED ON THE REAR DEFROST BUTTON SMOKE STARTED TO COME OUT FROM INSIDE THE STEERING WHEEL COLUMN. I COULD NOT GET THE REAR DEFROST TO TURN OFF SO I HAD TO TURN OFF THE CAR AND REMOVE THE FUSE TO IT. SHORTLY AFTER THIS INCIDENT THE POWER WINDOWS HAVE STOPPED WORKING AND THE FUSE TO THEM IS STILL GOOD, I REPLACED IT JUST IN CASE BUT THE WINDOWS STILL DO NOT WORK. THE ODOMETER HAS ALSO STOPPED WORKING SO I HAVE HAD TO GUESS MY SPEED. I FEEL THAT THIS IS A HUGE SAFETY CONCERN SINCE THE REAR DEFROST DOES NOT WORK I CANNOT SEE OUT THE REAR WINDOW ON COLD DAYS, I ALSO CANNOT TELL HOW FAST I AM DRIVING WHICH CAN CAUSE AN ACCIDENT, AND THE POWER WINDOWS HAVE STOPPED WORKING. THE CAR IS DUE FOR INSPECTION NEXT MONTH AND I CANNOT AFFORD TO FIX THESE PROBLEMS, THIS IS MY ONLY VEHICLE AND RELY ON IT TO GET TO AND FROM WORK EVERYDAY. I HAVE ALSO PLACED A COMPLAINT WITH GENERAL MOTORS CONCERNING THIS ISSUE AS I FEEL THAT THE PROBLEMS THAT HAVE OCCURRED ARE A RESULT OF POOR OR HURRIED WORKMANSHIP IN THAT AREA OF THE VEHICLE'S MANUFACTURE. *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.
