Dear General Motors Customer:

This letter is sent to you in accordance with the Canada Motor Vehicle Safety Act.

General Motors of Canada has determined that certain 1985 Pontiac Grand AM, models produced for sale in Canada were assembled with front and rear bumper impact bars which do not meet the CMVSS 8 KPH (5 mph) impact requirements.

Although you have previously been notified of this condition, and may have had the correction performed by your Dealer, further modifications are required.

The front bumper impact bar will be replaced on those vehicles previously repaired and the front and rear bumper impact bars will be replaced on the others. Please contact your GM dealer to arrange a service appointment.

The labour time required to perform this modification is 1 to 2 hours. Please allow your dealer additional time to process your vehicle. This correction will be made at no cost to you.

This letter identifies your vehicle. Presentation of this letter to your Dealer will assist their Service personnel in completing the necessary correction to your vehicle in the shortest possible time.

Further assistance, if required, may be obtained from the General Motors Zone Office nearest you. Your vehicle Owner's Manual provides the location and phone number of each respective Zone Office.

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