September 2008

Dear General Motors Customer:

We have learned that your 2008 model year Buick Enclave or 2007-2008 model year GMC
Acadia or Saturn OUTLOOK, equipped with a sunroof, may have a condition in which water is
not properly drained away from the sunroof. If this condition were to occur, water may enter the
interior of the vehicle and dampen the carpet, upholstery, and other interior components.

Your satisfaction with your Buick Enclave, GMC Acadia, or Saturn OUTLOOK is very important
to us, SO we are announcing a program to prevent this condition or, if it has occurred, to fix it.

What We Will Do: Your GM dealer/retailer will install drain tube extension assemblies and
ensure that the water drains properly. This service will be performed for you at no charge until
September 30, 2009.

What You Should Do: To limit any possible inconvenience, we recommend that you contact
your dealer/retailer as soon as possible to schedule an appointment for this repair. By
scheduling an appointment, your dealer/retailer can ensure that the necessary parts will be
available on your scheduled appointment date.

Customer Reply Form: The enclosed customer reply form identifies your vehicle. Presentation
of this form to your dealer/retailer will assist in making the necessary correction in the shortest
possible time. If you no longer own this vehicle, please let us know by completing the form and
mailing it back to us.

If you have any questions or need any assistance to better understand related repairs, please
contact your dealer/retailer.

Courtesy Transportation: If your vehicle is within the New Vehicle Limited Warranty your
dealer/retailer may provide you with shuttle service or some other form of courtesy
transportation while your vehicle is at the dealership/facility for this repair. Please refer to your
Owner’s Manual and your dealer/retailer for details on Courtesy Transportation.

We sincerely regret any inconvenience or concern that this situation may cause you. We want
you to know that we will do our best, throughout your ownership experience, to ensure that your
GM vehicle provides you many miles of enjoyable driving.
