Procedures covering this campaign are outlined in Section V of your dealership's "GM Truck Claims Processing Manual" #P 8819.
Dear GMC Truck Owner:
This notice is sent to you in acordance 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 exits in certain 1989 CK 15-35 extended cab model trucks produced at
the Oshawa Truck Assembly Center. These vehicles may have below specified torque on the optional trailer hitch (VR4) attaching fasteners. This
incorrect torque could allow the trailer hitch to move under towing loads. This could eventually lead to failure of the fasteners. If this occurs while a
trader is being pulled, the hitch and trailer could separate and a vehicle crash could occur without prior warning.
To correct this condition, it will be necessary to inspect for evidence of trailer hitch movement, and if movement has occurred, the attaching fasteners
will be replaced and tightened to the specified torque. If no movement has occurred, the attaching fasteners will be tightened to the specified torque. This
service will be performed for you at no charge.
Instructions for performing this service have been sent to your GMC Track dealer. Parts are available. Please contact your dealer to arrange a service
date. The labor time necessary to perform this correction will be approximately 30 minutes. Please ask your dealer how much additional time will be
needed to process your vehicle.
Your GMC Truck dealer is best equipped to obtain parts and 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, you are still not satisfied that we have done our best to remedy thin 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 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 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 safety and continued satisfaction with our
products.
