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.

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.
