CAMPAIGN: DEFORMATION OF FRONT AND REAR BUMPER BRACKETS. Buick LeSabre 1984

MODELS AFFECTED: 1984 Electras, LeSabres, and Rivieras

General Motors has determined that the 1984 Electra, LeSabre, and Riviera front bumper brackets, and the 1984 LeSabre rear bumper brackets may deform when lifting and towing the vehicle.

To prevent this condition from occurring on these vehicles, dealers are to replace the bumper brackets with new reinforced brackets, as instructed in the Technical Procedures of this bulletin.

DEALER CAMPAIGN RESPONSIBILITY

Dealers are to service all vehicles subject to this campaign at no charge to owners, regardless of mileage, age of vehicle, or ownership, from this time forward.

Whenever a vehicle subject to this campaign is taken into your new or used vehicle inventory, or it is in your dealership for service in the future, you should take the steps necessary to be sure the campaign correction has been made before reselling 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.

DEALER MATERIAL

If your dealership has vehicles involved in this campaign, you will receive the following items:

List of all vehicles involved in this campaign shipped to your dealership.

One campaign identification label for each vehicle.

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 furnished will enable dealers to follow up with owners involved in this campaign.

These 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.

TRANSFER OF VEHICLE

If a vehicle has been transferred or sold to another location, please forward vehicle information for this vehicle to your Buick Zone Office for handling with the proper dealer.

OWNER NOTIFICATION

Owners of vehicles involved in this campaign will be notified by Buick Motor Division (See copy of Owner Letters included with this bulletin).

CHANGE OF OWNER INFORMATION

Dealers are to use the Dealer Communication System (D.C.S.) 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 D.C.S., the need to send in an S-866 Form for that vehicle is eliminated. Terminal input instructions are covered in the D.C.S. Manual under Section 9, page 9-J01A and B.

PARTS INFORMATION

The parts for this campaign are to be obtained from WDDGM. Since these brackets are used only for this campaign, order for your immediate needs. These brackets will not be used as service replacement parts. To ensure these parts will be obtained as soon as possible, they should be ordered on a C.I.O. order with no special instruction code, but order on an advise code (2).

A right and a left bracket are required for each bumper to be campaigned. To determine if a LeSabre requires both front and rear bumper brackets, refer to the vehicle printout furnished with this campaign.

If an "A" is listed to the right of the "Camp ID" number on the list, only the front bumper brackets are to be replaced.

If a "B" is listed, only the rear bumper brackets are to be replaced.

If a "C" is listed, both front and rear brackets are to be replaced.

Refer to chart to obtain correct bumper brackets for a vehicle.

General Motors bulletins are intended for use by professional technicians, not a "do-it-yourselfer". They are written to inform those 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 a General Motors dealer servicing your brand of General Motors vehicle for information on whether your vehicle may benefit from the information.
