General Motors has determined that two defects which relate to motor vehicle safety exist in your 1980 Chevrolet Citation. The stearing gear mounting plate on your vehicle may develop fatigue cracks at high mileage which should allow the steering gear attachment to become loose.

If a vehicle is operated with this condition and a driver encounters circumstances which require full steering control, a vehicle crash could occur without prior warning. With regard to an automatic transmission coolor line hose failure, potential fluid leakage could result in a vehicle fire and possible injury.

To prevent the occurrence of either of the above described conditions on your vehicle, please contact your Chevrolet Dealer to arrange for an appointment to have the transmission cooler hoses replaced and a new type steering gear mounting bracket installed on your vehicle. Both corrections will be performed at no charge to you. It is estimated that parts will be available at your dealer on or after (to be determined).
