Dear Buick Owner:

General Motors has determined that some early 1986 Centurys equipped with 3.8L engines may have been assembled with the engine "Electronic Control Module" (ECM) wiring harness misrouted. This may result in the wiring harness shorting against the exhaust manifold in the engine compartment. This condition could cause engine starting problems and poor engine performance.

To prevent this condition from occurring on your vehicle, your Buick dealer will inspect and when required, reroute or repair the ECM wiring harness. This service will be performed for you at no charge.

Instructions for this service have been sent to your Buick dealer. Please contact your dealer to arrange a service date. The labor time to inspect your vehicle is approximately 15 minutes. If the wiring harness must be rerouted or repaired, it will take an additional 45 minutes. Please ask your dealer if you wish to know how much additional time will be needed to process your vehicle.

The enclosed owner reply card identifies your vehicle. Presentation of this card to your dealer will assist in making the necessary 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 returning it to us.

We are sorry to cause you this inconvenience; however, we have taken this action in the interest of your continued satisfaction with our products.
