WHEN THE CONSUMER MADE A RIGHT TURN A NOISE WAS HEARD. THE LEFT REAR TURN SIGNAL BULB WAS REPLACED, THE RIGHT REAR BRAKE LIGHT BULB. THERE WAS A NOISE COMING FROM THE FRONT OF THE VEHICLE, THE DEALER LUBED THE FRONT SWAY BAR BUSHING. THE TIRES WERE OVER INFLATED, SO THE VEHICLE WOULD SWAY WHEN GOING OVER BUMPS, THE BLOWER MOTOR, AND HEATER CONTROL WAS REPLACED. THE ABS LAMP ILLUMINATED. THE VEHICLE NEEDED BRAKE PADS. THERE WAS MOLD ON THE DRIVERS FRONT DOOR. THE AC COMPRESSOR WAS REPLACED. THE WINDOW WENT DOWN EXTREMELY SLOW, THE DEALER LUBED THE WINDOW TRACK AND REGULATOR. THE FOG LIGHT BULB WAS INOPERATIVE, THE DOOR LATCH WAS INOPERATIVE. *JB

I'VE OWNED MY 2003 CAVALIER FOR 1 YR. 3 MONTHS. I'M VERY IRRITATED WITH HAVING TO GO TO THE DEALERSHIP EVERY OTHER MONTH FOR THE SAME PROBLEM. I'VE HAD MY CAR IN 7 TIMES TO GET THE TAILLIGHT FIXED. THE FIRST 2 TIMES THE LIGHT BLEW OUT, MY RADIO COMPLETELY WIPED OUT MY PRESET STATIONS. I ALSO HAD MY CAR IN 2 MONTHS AFTER I BOUGHT IT BECAUSE THERE WAS A BAD SNOW AND AS I WAS DRIVING 5 MPH I BUMPED OVER A POT HOLE WHICH ENDED UP CRACKING MY SPRING AND STRUT ON THE FRONT PASS. SIDE. I HAD TO PAY OUT OF POCKET BECAUSE THE REPAIR WAS $100 LESS THAN MY DEDUCTIBLE. AND I WAS IN THE SERVICE DEPT. A WEEK BEFORE COMPLAINING OF A SQUEAK COMING FROM MY FRONT TIRE THAT THEY PUT OFF AS THE WHEEL COVER.COINCIDENCE?THERE WAS NO REASON THAT THE SPRING AND STRUT SHOULD HAVE CRACKED LIKE THAT! I'VE ALSO, JUST FOR THE RECORD, ASKED THEM TWICE TO CHECK MY BRAKES BECAUSE AS I COME TO A STOP THEY BEGIN TO PULSATE. THE SERVICE DEPT. TOLD ME I NEEDED NEW BRAKES.I'VE ONLY HAD MY CAR FOR 1 YEAR, 24,000 MOSTLY HIGHWAY MILES!!! THEY WANT $250.00 TO FIX MY BRAKES AND THEY SHOULD STILL BE UNDER WARRANTY. EVEN MIDAS GURANTEES THEIR BRAKES W/ A LIFETIME WARRANTY. YOU'D THINK THE MANUFACTURER WOULD FOR AN ORIGINAL OWNER.IT'S ONLY 2 PADS FOR GOODNESS SAKE! IF I KNEW HOW, I'D DO IT MYSELF. A SERVICE TECH TOLD ME THAT GM IS WELL AWARE OF THESE SAFETY HAZARDS THAT OTHER GM CUSTOMERS LIKE MYSELF ARE EXPERIENCING, YET THEY AREN'T DOING A RECALL. SOMETHING NEEDS TO BE DONE BEFORE SOMETHING BAD HAPPENS TO SOMEONE WHILE IN THEIR VEHICLE. NOT DOING ANYTHING IS BAD BUSINESS!! CUSTOMERS SHOULD BE FIRST PRIORITY. AS A MANUFACTURER, YOUR RESPONSIBILITY IS TOWARD YOUR CUSTOMER IF SOMETHING YOU SELL OR MANUFACTURE IS DEFECTIVE!!!*AK

THE TIRES SHAKE AND VIBRATE AROUND SIXTY MILES/HR. SO I TOOK THEM TO SAM'S CLUB TO THEIR TIRE CENTER IN DECEMBER OF 2003. THEY ROTATED AND BALANCED THE TIRES. I DROVE THE CAR FOR ONE MONTH, THEN THE TIRES STARTED DOING THE SAME THING OVER AGAIN. ABOUT ONE MONTH LATER, I WENT BACK TO SAM'S CLUB AND THEY BALANCED MY TIRES AGAIN. SO HERE IT IS MARCH OF 2004, THE TIRES ARE DOING THE SAME THING AGAIN SHAKING AND VIBRATING AROUND SIXTY MILES/HR. I CALLED GOODYEAR , THEY TOLD ME TO BRING THE CAR IN. THEY LOOKED AT THE TIRES, AND SAID THAT THE REAR TIRES WERE WORN ON THE INSIDE, AND THAT I WOULD HAVE TO TAKE THE CAR BACK TO THE DEALERSHIP TO GET THE TIRES FIXED. THEY COULD NOT DIAGNOSE THE SPECIFIC ORIGIN OF THE VIBRATION. BASICALLY, FOR A BRAND NEW CAR, WE SHOULD NOT HAVE THESE KIND OF PROBLEMS AT 24,000 MILES (AS STATED BY MECHANICS FROM GOODYEAR, SAM'S CLUB AND FIRESTONE). 5. CRUISE CONTROL SWITCH- IF RIGHT TURN SIGNAL IS USED WHEN CRUISE CONTROL IS ACTIVATED, THE CRUISE CONTROL WILL AUTOMATICALLY DEACTIVATE ITSELF. 6. POWER FAILURE- CAR ALL OF A SUDDEN LOST POWER WHILE AT A STOPLIGHT. 7. A/C & HEATER- A/C AND HEATER MAKE LOUD NOISE. 8. REAR TURN SIGNAL LIGHT BULBS BURNED OUT 4 TIMES ON EACH SIDE. GM REPLACEMENT BULBS LAST ONLY 1 TO 1 1/2 MONTH. *NM

WHEN APPLYING THE BRAKES AT NIGHT, THE HEADLIGHTS AND DASH LIGHTS DIM TO A SOFTER SHADE OF LIGHT. I HAVE ALSO CHANGED THE REAR SINGLE LIGHTS IN MY CAR THREE TIMES IN THE PAST 6 MONTHS. THIS CAR HAS A BAD BRAKE PROBLEM. THE FRONT OF THE CAR SHAKES VERY BAD WHEN YOU APPLY THE BRAKES WHILE EXITING A HIGHWAY. CITY DRIVING IS NOT AS BAD, BUT WHEN THE BRAKES GET WARMED UP THEY PULSATE WHEN I COME TO A STOP. AT THE END OF THE DAY, I PULL MY CAR INTO MY DRIVEWAY AND THE FIRST THING I SMELL WHEN I GET OUT IS A BURNING SMELL FROM THE BACK BRAKES. I CALLED THE FUCILLO CHEVY SERVICE DEPARTMENT IN DECEMBER 2003. I TALKED TO A SERVICEMAN ABOUT MY BRAKE PROBLEM. HE TOLD ME THAT MY PULSATING BRAKES IS THE ABS SYSTEM WORKING IN THE SNOW. NOW THE ROADS ARE DRY AND MY BRAKES ARE STILL PULSATING. I COULD NOT FIND ANYTHING IN MY ORIGINAL PAPERWORK ON MY CAR SHOWING THAT IT HAS THE ABS SYSTEM. NOW MY BRAKES ARE SHOT. THE CAR HAD ONLY 6500 HUNDRED MILES ON IT WHEN I FIRST CALLED IN DECEMBER OF 2003. IN JUNE OF 2003, I BOUGHT THIS CAR AND TEST DROVE IT. THE CAR SEEMED TO BE A GOOD CAR, EXCEPT FOR THE NOISE THAT I HEARD COMING FROM THE FRONT LEFT TIRE AREA. IT SOUNDED LIKE A RUBBER BAND WHEN IT SNAPS. I BROUGHT IT UP TO MY SALESMEN ROCKY FROM THE CHEVY DEPARTMENT. HE TOLD ME THAT IT'S A NEW CAR. NOW WHEN THE FRONT TIRES ARE TURNED TO THE RIGHT, IT MAKES A CRUNCHING NOISE. WHEN I DRIVE OVER ANY BUMP AT ANY SPEED, IT FEELS LIKE THERE ARE NO SHOCKS OR STRUTS ON THIS CAR AND MAKES A BAD CLUNKING SOUND. *NM

WITH ONLY .5 INCHES OF SNOW MY CAR (A 2003 CHEVY CAVALIER) LOST COMPLETE CONTROL AND SMASHED INTO THE CURB. THIS WAS WHILE TRAVELING AT LESS THAN 10MPH. I FEEL THE COMBINATION OF 16" TIRES AND THE SPORTS SUSPENSION (BOTH STANDARD ON THE CAR) WAS THE CAUSE OF THE ACCIDENT. *AK

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.
