I WAS INFORMED BY A CUSTOMER SERVICE REP AT CHEVROLET ON 9/5/03 THAT MY VEHICLE WAS COVERED FOR HEAD GASKET REPAIR UNDER A "SPECIAL POLICY" RECALL. AT THE URGING OF THIS CUSTOMER SERVICE REP FROM CHEVROLET, BRUCE MITCHELL, I TOOK MY VEHICLE TO THE DEALER FOR REPAIR. I WAS NOTIFIED BY THEIR SERVICE DEPT. THAT THIS "SPECIAL POLICY" EXPIRED 7/03 AND THAT IT WOULD COST OVER $1,400 TO FIX ALL OF THE DAMAGES INCLUDING THE HEAD GASKET. I TOLD THE DEALERSHIP NOT TO FIX THE PROBLEMS. I CALLED CHEVROLET AND SPOKE WITH THE SAME CUSTOMER SERVICE REPRESENTATIVE AS I HAD EARLIER. HE APOLOGIZED AND INFORMED ME THAT HE WAS INCORRECT IN TELLING ME THAT THE HEAD GASKET WOULD BE COVERED AT NO COST. I PURCHASED THIS VECHICLE FROM A PRIVATE SALE IN 2/03. I WAS NEVER INFORMED BY ANYONE THAT ANY RECALLS WERE AVAILABLE TO ME. MY VEHICLE STARTED HAVING PROBLEMS A COUPLE OF WEEKS AGO, SO I LOOKED ON CHEVROLET'S WEBSITE TO SEE IF PERHAPS THERE WERE ANY RECALLS OUT FOR MY CAR AND THERE WERE 2 AND THIS OTHER "SPECIAL POLICY". I ASKED THE COMPANY HOW I WAS SUPPOSED TO KNOW THAT THIS POLICY HAD AN EXPIRATION DATE IF I NEVER KNEW ABOUT IT IN THE FIRST PLACE. THEY TOLD ME THAT THEY DID ALL THAT THEY CAN DO AND THAT THEY CANNOT HELP ME. I CANNOT AFFORD TO GET MY VEHICLE FIXED SO THEREFORE IT IS UNDRIVABLE TO ME. I THINK THAT THIS IS RIDICULOUS. I MISSED THE EXPIRATION DATE BY 2 MONTHS BECAUSE OF AN EXPIRED POLICY THAT I NEVER KNEW ABOUT, OR WOULD HAVE KNOWN ABOUT IF I DIDN'T TAKE IT UPON MYSELF TO CONDUCT SOME RESEARCH ON THE CHEVROLET WEBSITE AND TAKE THE INITIATIVE TO CALL THEIR COMPANY. I'M FRUSTRATED AND ANGRY THAT A CUSTOMER SERVICE REPRESENTATIVE GOT THIS INFORMATION SO WRONG. NOW I'M STUCK.....I WOULD NOT HAVE TAKEN THIS VEHICLE TO THE DEALERSHIP FOR REPAIR IF I WOULD HAVE NOT BEEN MISINFORMED.*AK

Official recalls
104V524000 · Exterior Lighting:turn Signal
Nov 1, 2004
ON CERTAIN PASSENGER VEHICLES, THE REAR LAMPS THAT PROVIDE STOP AND TURN SIGNALS AND TAIL LAMP FUNCTIONS STOP WORKING BECAUSE OF INADEQUATE CONTACT BETWEEN THE BULB AND SOCKET. IN ADDITION, IF ONE BULBS WERE TO BECOME INOPERATIVE WHILE THE VEHICLE WAS OPERATING IN CRUISE CONTROL, THE CRUISE CONTROL WOULD DISENGAGE WHEN THE REMAINING BULB WAS ACTIVATED. IF BOTH LAMPS WERE TO BECOME INOPERATIVE, THE CRUISE CONTROL WOULD NOT ENGAGE.
Consequence & remedy
Consequence: AN INOPERATIVE BRAKE LAMP WILL NOT CONVEY THE DRIVER'S INTENTION OF STOPPING TO DRIVERS IN FOLLOWING VEHICLES, AND AN INOPERATIVE REAR TURN SIGNAL LAMP WILL NOT CONVEY THE DRIVER'S INTENTION TO TURN TO DRIVERS IN FOLLOWING VEHICLES. BOTH OF THESE FAILURES CAN INCREASE THE RISK OF A CRASH.
Remedy: DEALERS WILL INSPECT THE REAR LAMP BULB SOCKET ASSEMBLIES AND APPLY GREASE OR REPLACE THEM IF NECESSARY. THE RECALL BEGAN ON JANUARY 18, 2005. OWNERS SHOULD CONTACT CHEVROLET AT 1-800-630-2438 OR PONTIAC AT 1-800-620-7668.

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.
