MY GAUGE CLUSTER WENT OUT WHILE GOING DOWN THE HIGHWAY. VERY UNSAFE, I WAS UNSURE OF THE HEAT OF THE ENGINE AND IT IS ONE OF THE HOTTER DAYS OF THE YEAR!!!! LOOKED ON-LINE AND FOUND HOW COMMON THIS ISSUE IS. I CANT SEE HOW MUCH GAS I HAVE, HOW HOT MY CAR IS, HOW FAST IM GOING, OR HOW HARD MY CAR IS WORKING. IF THIS PIECE OF EQUIPMENT IS FAILING SO WIDELY IT NEEDS TO BE RECALLED!!!!!!!!! VERY VERY VERY UNSAFE. TRIED TO TAKE TO ADVANCED AND THEY WONT READ THE CODE AS ITS NOT A STANDARD CODE (?) GM YOU ARE LOOSING CUSTOMERS FAST AND PUTTING THOUSANDS OF LIVES AT RISK BY LETTING THIS CONTINUE TO GO PAST YOU AND ALL FOR THE SAKE OF A LITTLE MONEY TO FIX A PROBLEM YOU SOLD TO US? IF YOU CAN RECALL THE SAME ISSUE ON SOME OF YOUR TRUCKS YOU CAN ON THIS CAR AS WELL, DISCONTINUED OR NOT. *JS

IN RESPONSE TO PREVIOUS INVESTIGATION NHTSA ACTION NUMBER PE07033 I WAS DRIVING MY 2003 CHEVY CAVALIER ON 95 SOUTH BOUND, WHEN THE TRAC OFF LIGHT CAME ON AND THE VEHICLE JERKED AND STALLED A LITTLE BIT. I ATTEMPTED TO CONTINUE DRIVING, HOWEVER NOTICED THE VEHICLE STALLING EVEN MORE. I WAS IN AN EXTREMELY DANGEROUS PLACE IN HIGHWAY TRAFFIC, AND KNEW I HAD TO PULL OFF THE ROAD IMMEDIATELY. MY CAR SHUT OFF AS I WAS PULLING TO THE RIGHT SHOULDER OF THE HIGHWAY AND I WAS ALMOST HIT BY VEHICLES GOING 60-70 MPH. I WAS ABLE TO COAST TO THE SHOULDER OF THE ROAD - IN A POSITION WHERE I WAS NOT EVEN ABLE TO EXIT MY VEHICLE FROM THE DRIVER SIDE. I HAD THE VEHICLE TOWED TO MY MECHANIC, WHO INFORMED ME THAT THE FUEL PUMP AND FUEL FILTER NEED TO BE REPLACED. THIS IS GOING TO COST ME APPROXIMATELY $417. I HAVE RESEARCHED THIS PROBLEM ON THE WEB AND FIND IT TO BE EXTREMELY COMMON. TO SAY THAT THIS ISN'T A BIG PROBLEM WITH THIS TYPE OF VEHICLE IS UNFAIR. *TR

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

FUEL PUMP FAILURE - REPLACEMENT LEARNED OF REPLACEMENT WIRING HARNESS - RECOMMENDED BY GENERAL MOTORS DUE TO POSSIBILITY OF FUEL TANK CATCHING FIRE DUE TO A DEFECTIVE CONNECTOR REPLACEMENT WAS NOT A HARNESS BUT A CONNECTOR THAT HAD TO BE SPLICED INTO EXISTING CABLE WHICH WAS AROUND 30 OR SO INCHES LONG DEALERSHIP SAYS SPLICE CONNECTOR IS ONLY ALTERNATIVE TO REPLACING THE ENTIRE CABLE WHICH WOULD RUN OVER $500 AND WOULD HAVE TO CUT AND SPLICE THAT TOGETHER AS WELL AS NEW ONE WOULD HAVE THE DEFECTIVE CONNECTOR AS WELL ** MY COMPLAINT ON THIS - THIS IS A FACTORY DEFECT OR SO THE DEALERSHIP SAYS AND IS AWARE OF THE PROBLEM WHICH INDICATED THAT THE HARNESS NEEDS REPLACEMENT DUE TO FACT THAT USING EXISTING CONNECTOR INSTALLED BY THE MANUFACTURER COULD CAUSE A FIRE IN THE FUEL TANK - WHICH I WOULD THINK THIS IS A SAFETY ISSUE THAT SHOULD HAVE HAD A RECALL TO IT. ** ALSO REPLACING A CONNECTOR BY SPLICING IS PRETTY MUCH POINTLESS ON SUCH A SHORT CABLE TO BEGIN WITH AND IF A DIY WAS TO DO THIS THE CONNECTION MAY NOT BE SOLID AND TIGHT THEREFORE A HEAT BUILD UP COULD OCCUR AND A FIRE COULD RESULT AS WELL. *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.
