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 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 used vehicle inventory are to be contacted by the dealer, and arrangements made to make the required modifications according to instructions contained in this bulletin. If there is evidence of intentional disablement of the emission system, the dealer is to notify the vehicle owner of this condition and ask if he/she wants the system restored. Restoration cost is the responsibility of the owner.
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 in the area of 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 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. Any dealer not receiving a computer listing with the campaign bulletin has no involved vehicles currently assigned.
OWNER NOTIFICATION
Owners will be notified of this campaign on their vehicles by Buick Motor Division (see copy of owner letter included with 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 0CS, 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.

NOTICE: An initial supply of parts are being forwarded to you through the GMSPO Campaign Parts Pre-Ship Program. All dealers with involved vehicle(s) are being shipped 25% of their requirement or a minimum of one PROM. These parts will be billed on the dealer parts account.
Additional parts required to complete this campaign are to be obtained from General Motors Service Parts Operation (GMSPO). To ensure these parts will be obtained as soon as possible, they should be ordered from GMSPO on a C.I.O. order with NO special instruction code, but on an advise code (2).

Dear Buick Owner:
This notice is sent to you to inform you that Buick Motor Division is conducting an emission recall that includes your vehicle.
REASON FOR THIS RECALL
Environmental Protection Agency (EPA) testing has shown that certain 1987 Buick Regal models equipped with the 3.8L Turbo Sequential Fuel Injected (SFI) engines and Federal emissions equipment may be emitting pollutants in excess of Federal Emission Standards. These standards were established to protect the public health and/or welfare from the dangers of air pollution. This condition could cause a vehicle to fail an emission test, if required under state or local law.
WHAT WE WILL DO
To correct this condition, the PROM assembly in the engine Electronic Control Module (ECM) will be replaced. This service will be performed at no charge to you.
WHAT YOU SHOULD DO
Please contact your Buick Service Department dealer to arrange a service date. We suggest you go to your selling or servicing dealer, but you may go to any Buick dealer for this service. Instructions for providing this service have been sent to your dealer and parts are currently available. The labor time necessary to make this correction is approximately twenty (20) minutes. Please ask your dealer if you wish to know how much additional time will be needed to schedule and process your vehicle.
The enclosed owner reply card identifies your vehicle. Presentation of this card to your dealer will assist in making the correction in the shortest possible time. If you have sold or traded your vehicle, please let us know by completing the postage paid Owner Reply Card and return it to us. Should your dealer not schedule a service date within a reasonable time, please contact the Buick Customer Assistance Center, Flint Home Office, by calling 1-800-521-7300.
If your dealer and the Buick Customer Assistance Center are unable to remedy the condition within a reasonable time, you may wish to advise the Environmental Protection Agency at the following address: Director Manufacturers Operations Division (EN-340F), United States Environmental Protection Agency, 401 M. Street, S.W. Washington, DC 20460.
To ensure your full protection under the emission warranty made applicable to your vehicle by Federal Law, and your right to participate in future recalls, it is recommended that you have your vehicle serviced as soon as possible. Failure to do so could legally be determined to be lack of proper maintenance of your vehicle. Also, your vehicle may fail a state or local emission inspection test if the recall work is not accomplished.
Should your dealer find that your emission system has been intentionally disabled, you will be asked if you wish the system to be restored so that it will function as designed. The cost of such restoration will be your responsibility.
We are sorry to cause you this inconvenience, however, we have taken this action to assure that your vehicle meets applicable government emission requirements and in the interest of your continued satisfaction with our products.
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.
