1. BOTH BRAKE LIGHTS WENT OUT W/IN MONTH OF EACH OTHER. IN THE MONTHS OF JULY AND AUGUST. 2. BRAKES NOISY, SEPTEMBER 3. TRUNK WOULD NOT OPEN, OCTOBER 4. BRAKES NOISY, AGAIN, NOVEMBER 5. CAR TURNS OFF IN THE MIDDLE OF AN INTERSECTION AFTER MAKING A COMPLETE STOP AND TRYING TO SPEED UP. FREAKING OUT, I PRESSED THE GAS AND MOVED THE KEY IN THE IGNITION, THEN PUT CAR IN PARK AND GOT IT TO START, NOVEMBER. IT JUST SEEMS TO ME THAT I HAVE A DISFUNCTIONAL CAR THAT WHEN I DONT HAVE SOMETHING WRONG WITH ONE THING I HAVE TO GO IN TO THE DEALER FOR ANOTHER. ITS A NEW CAR AND ITS COSTING ME MORE PROBLMES AND INCONVINIENCES THAN THE OLD '96 I HAD TILL I BOUGHT THIS ONE.

WHILE DRIVING AT 45 - 50 MPH ON THE HIGHWAY THE TRANSMISSION COMPLETELY FAILED, WITHOUT WARNING AND THE WHEELS ON THE CAR LOCKED UP. THE CAR CAME TO A COMPLETE STOP WITHOUT WARNING AND 3 CARS SWERVED OFF THE ROAD TO AVOID A REAR END COLLISION. ONCE OUT OF THE CAR IT COULD NOT EVEN BE PUSHED OFF THE ROAD. THE MECHANIC NOTED THAT ALL THE EGEARS WERE BROKEN AND THE TRANSMISSION COULD NOT EVEN BE REBUILT. A TRANSMISSION HAD TO BE PULLED FROM TOTALLED CAVALIER AND REBUILT TO GET MY CAR RUNNING. WITHOUT THE REBUILT TRANSMISSION, PARTS COULD HAVE COST UP TO $2500 PLUS LABOR. I WAS DISAPPOINTED/SCARED THAT SUCH A THING COULD HAPPEN WITHOUT WARNING. HAD I BEEN DRIVING ON THE INTERSTATE I COULD HAVE BEEN KILLED OR SERIOUSLY INJURED IF ANOTHER CAR HAD HIT US. I WAS DISAPPOINTED BECAUSE I TAKE VERY GOOD CARE OF MY CAR AND HAVE NEVER HAD ANY SERIOUS PROBLEMS WITH IT.

SAID IF THEY CAN'T FIND THE PROBLEM THEN THEY CAN'T FIX IT AND TO DRIVE IT UNTIL WHATEVER IT IS BREAKS OR FALLS OUT! I STILL HAVE THE PROBLEM AND I AM TERRIFIED TO DRIVE IT.ALSO THE SEAT BELT LIGHT DOES NOT WORK PROPERLY,THE DASH HAS A LOUD VIBRATING NOISE,THE HEAT AND AIR MAKES A LOUD BUZZING SOUND, THE GAS GAUGE DOES NOT WORK PROPERLY AND THE CAR DOES NOT ACCELERATE AND DECELERATE PROPERLY.I HAVE CONTACTED THE MANUFACTURER ABOUT THE PROBLEM AND THEY SAID THEY WERE SORRY ABOUT THE BOLTS NEVER BEING PUT IN AND THAT THEIR VEHICLES ARE INSPECTED AND ARE SAFE.WELL HOW IS THAT WHEN THEY DID NOT EVEN PUT IN BOLTS THAT HOLDS THE MOTOR IN?WHAT ELSE HAVE THEY FORGOTTEN?I FEEL UNSAFE IN MY CAR AND AM VERY ANGRY THAT THIS PROBLEM PERSISTS!

I HAVE A MAJOR PROBLEM WITH A VEHICLE THAT I RECENTLY PURCHASED. I BOUGHT A 2003 CAVALIER AND THERE WAS A PROBLEM WITH IT LAST WEEK. I NEED TO KNOW EXACTLY WHO TO TALK TO BEFORE I TAKE ANY FURTHER ACTIONS. MY CAR IS SUPPOSED TO HAVE AN EXTENDED WARRANTY ON IT AND I KNOW THAT I'M SUPPOSED TO BE ABLE TO GET A RENTAL CAR. WELL, HERE'S THE SITUATION LAST WEEK, I WAS DRIVING MY CAR AND WENT TO MAKE A TURN AND MY STEERING WHEEL LOCKED UP WHILE I WAS DRIVING. I WAS ON THE WAY TO TAKE IT TO BE LOOKED AT AND IT HAPPPENED AGAIN, BUT WHEN I TRIED TO STOP, THE CAR JUST KEPT GOING AND CAUSED ME TO CRASH INTO ANOTHER VEHICLE. WHEN I WENT TO THE DEALERSHIP TO SPEAK TO SOMEONE, THEY OFFERED NO HELP AS FAR AS MY RENTAL AND WARRANTY. I AM ANGRY BECAUSE THIS FLAW WITH THE CAR COULD'VE RESULTED IN MY DEATH. IT TOOK OVER A MONTH TO GET SOMEONE TO COME TAKE A LOOK AT THE CAR AND WHEN SOMEONE FINALLY CAME ON NOV. 2, THEY SAID THEY DIDN'T FIND ANYTHING WRONG AND THAT WAS IT. I TRIED MAKING CONTACT AGAIN AND GOT NO RESPONSE. I'M STILL WITHOUT MY VEHICLE BECAUSE EVEN IF I PAY TO HAVE IT REPAIRED, THERE IS STILL THE CHANCE THAT IT COULD HAPPEN AGAIN.*AK

IF THE CLUTCH IS RE-ENGAGED THEN THE RPM RATE RETURNS TO THE NORMAL RANGE FOR THE GEAR/SPEED OF TRAVEL. IF THE CAR IS BRAKED TO A COMPLETE STOP, THE RPM RATE FALLS TO THE NORMAL IDLE RATE AFTER 20-40 SECONDS OF STANDSTILL. THE BEHAVIOR HAS BEEN OBSERVED EVERYTIME EXTENDED HIGHWAY DRIVING IS COMPLETED. THE PROBLEM HAS BEEN REPORTED TO THE DEALERSHIP AND THE ON-BOARD DIAGNOSTIC SHOWS NO PROBLEM AND THE DEALERSHIP CAN NOT RECREATE THE PROBLEM.

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.
