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 1991
K 1-2 pickup trucks built at Ft. Wayne assembly plant. These vehicles may have an incorrect front wheelhouse splash shield that may contact the rubber
portion of the front brake hose, which could result in a sudden failure of the front hydraulic brake system. If this failure occurred, the rear brake system
still functions, but increased stopping distance would be required. Loss of front braking at time when minimum stopping distance is required could result
in a vehicle crash, without prior warning.
To prevent this condition from occurring, dealers are to inspect all suspect "K" model vehicles for incorrect splash shields and replace them with the
correct parts if required. Additionally, where there is an incorrect splash shield, the brake hose will be replaced. This service will be completed for you at
no charge.
Instructions for performing this service have been sent to your GMC dealer. Please contact your dealer to arrange a service date. The labor time
necessary to perform this correction will vary from 12 minutes to 54 minutes. Please ask your dealer how much additional time will be needed to process
your vehicle.
Your GMC 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.
