OWNER NOTIFICATION
Owners of vehicles involved in this campaign will be notified by Buick Motor Division (see copy of owner letter included with this bulletin).
DEALER CAMPAIGN RESPONSIBILITY
Dealers are to service all vehicles involved in this campaign at no charge to owners, regardless of mileage, age of vehicle, or ownership. Whenever a
vehicle subject to this campaign is taken into your new or used car inventory, dealers are to take the steps necessary to be sure the campaign correction
has been made before selling or releasing the vehicle.
Owners of vehicles recently sold from your new vehicle inventory are to be contacted by the dealer and arrangements made to make the required
modification according to instructions contained in this bulletin.
In addition, dealers are to perform the campaign on all affected vehicles as they are brought in for any kind of service.
DEALER MATERIAL
If your dealership has vehicles involved in this campaign, you will receive the following items:
-
Listing of all vehicles involved in this campaign shipped to your dealership.
-
One (1) Campaign Identification Label per vehicle involved.
Involved vehicles have been identified by Vehicle Identification Number computer listings. Computer listings contain the complete vehicle identification
number, owner name and address data, and are furnished to the involved dealers with the campaign bulletin. Owner name and address data will enable
dealers to follow-up with owners involved in this campaign.
These computer listings may contain owner names and addresses obtained from State Motor Vehicle Registration Records. The use of such motor
vehicle registration data for any other purpose is a violation of law in several states. Accordingly, you are urged to limit the use of this listing to the
follow-up necessary to complete this campaign.
Any dealer not receiving a computer listing with the campaign bulletin has no involved vehicles currently assigned.
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.
