Owner Notification, Parts and Technical Procedure Information
OWNER NOTIFICATIONOwners of vehicles involved in this campaign will be notified by Buick Motor Division (see copy of owner letter included in this bulletin).
CHANGE OF OWNER INFORMATION
Dealers are to use the Dealer Communication System (DCS) to provide Buick Motor Division with subsequent Buick Owner information. By reporting a change of owner name or address of a vehicle in campaign status over the DCS, the need to send a CVAR form for that vehicle is eliminated. Terminal input instructions are covered in the DCS Manual under Section 9, Page 9-J01A and B.

To ensure that these parts are obtained as soon as possible, they should be ordered as soon as possible.
