PACCAR issued a recall on the C500 model

On certain trucks, the rear hood mounting brackets can contact the front axle brake chamber during full axle articulation. If contact occurs, two possible scenarios may result: 1). The front brake chamber may be damaged, resulting in the loss of air or sudden full application of one of the brakes on the front axle or; 2). The front brake chamber may be damaged causing a reduction in braking capacity. Correction: Dealers will inspect the brake chamber and surrounding components for any damage and modify the rear hood support bracket to eliminate the potential for interference.
