Condition

Some customers may comment that there appears to be premature wear of the leather material on the driver’s or passenger bucket seatback in the bolster area.

Correction

Replace the seatback leather cover with a new cover that has additional felt added to the backside of the leather to increase durability. Also, the leather material in the bolster area has been changed to a more durable vinyl material. For information on replacing the seatback cover, see Service Manual Update Bulletin #99-08-50-002.

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.
