Owner Letter

Dear GMC Truck Owner:

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

General Motors has determined that a defect which relates to motor vehicle safety exists in certain 1985-86 P3 Commercial Model Trucks with 350 gas engines or 6.2L diesel engines, 1985-86 G3 Vans with 350 gas engines or 6.2L diesel engines and 1985-86 C3 Model trucks built without heavy duty front suspension. The left hand lower control arm can crack starting at the rear flange and progress to the ball joint mounting hole and eventually cause the lower ball joint to separate from the control arm. If this happens, a loss of vehicle steering control can occur which could result in a vehicle crash without prior warning.

To prevent this condition from occurring, dealers are to install a reinforcement brace to the left hand lower control arm. This service will be completed for you at no charge.

Instructions for performing this service have been sent to your GMC Truck dealer. Please contact your dealer to arrange a service date. The labor time necessary to perform this correction will be approximately one hour. Please ask your dealer how much additional time will be needed to process your vehicle.

Your GMC Truck dealer is best equipped to provide service to ensure your vehicle is corrected as promptly as possible. However, if you take your vehicle to your dealer on the agreed service date and they do not service this condition on that date or within five days, we recommend you contact your nearest GMC Truck Zone Office by telephone. The Zone Office will assist you and your dealer in getting your vehicle corrected. The telephone numbers of the Zone Offices are listed in your Warranty and Owner Assistance Information Manual.

After contacting your dealer and the Zone Office, if you are still not satisfied that we have done our best to remedy this condition without charge within a reasonable time, you may wish to write the Administrator, National Highway Traffic Safety Administration, 400 Seventh Street, S.W., Washington, D.C. 20590, or call 800-424-9393 (Washington, D.C. residents use 366-0123).

The enclosed postage paid owner reply card identifies your vehicle. Presentation of this card to your dealer will assist in making the necessary correction to your vehicle in the shortest possible time. If you have sold or traded your vehicle, please furnish us complete name and address of the person you sold or traded your vehicle to and return the card to us.

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