Dear General Motors Customer:

This notice is sent to you in accordance with the requirements of the Canada Motor Vehicle Safety Act.

General Motors of Canada has determined that a defect which relates to motor vehicle safety exists in some early production, 1985 Oldsmobile Calais, Pontiac Grand-AM and Buick Somerset Regal models.

To prevent this from occurring on your vehicle, please contact your GM Dealer to arrange a service date. The Dealer will tighten the tie rod end pinch bolts. This service will be completed for you at no charge.

The labour time to do the work will be about 20 minutes. Please ask your Dealer if you wish to know how much additional time will be necessary to process your vehicle.
