CONDITION:

SOME CUSTOMERS MAY COMMENT THAT THE WHITE PAINT AROUND THE DOOR HANDLE IS TURNING YELLOW.

CAUSE:

THE GREASE THAT IS USED TO LUBRICATE THE TUMBLERS IN THE LOCK CYLINDER MAY MIGRATE OUT OF THE CYLINDER AND STAIN THE PAINT.

CORRECTION:

REPLACE THE LOCK CYLINDER AND DOOR HANDLE. NEW LOCK CYLINDER KITS HAVE BEEN RELEASED. THE NEW KITS HAVE A BLACK TUBE OF GREASE IN THEM WHICH SHOULD BE USED ON WHITE VEHICLES. THE OLD KITS HAVE EITHER A CLEAR TUBE OR WHITE TUBE OF GREASE THAT CAN BE USED ON ANY VEHICLE EXCEPT WHITE PAINTED VEHICLES.

GM bulletins are intended for use by professional technicians, NOT a "do-it-yourselfer". They are written to inform these technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions, and know-how to do a job properly and safely. If a condition is described, DO NOT assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See your GM dealer for information on whether your vehicle may benefit from the information.
