Affected Units:: 3,707,064
The possibility exists that driving on unpaved road surfaces, particularly roads which are heavily graveled and which are extremely wavy or filled with chuckholes, at speeds which cause the car to pitch excessively, the front crossmember may scoop up loose stones or gravel and could be thrown into the engine compartment. It is possible for one of these stones to lodge between the steering coupling and the frame and cause increased steering effort or interference with steering control of the car when steering wheel is turned to the left.
Inspect and install shield on affected vehicles.
