In extremely cold conditions, these bendix relay valves may potentially develop internal leakage. Internal leakage can lead to air pressure being delivered to affected primary or secondary brake causing continuous brake application.

Risk: Unexpected continuous brake application can cause the brakes to overheat and lead to a fire. Unexpected continuous brake application can cause the driver to lose control of the vehicle, increasing the risk of a crash. Also, the brakes may be applied without illuminating the brake lights, failing to give proper warning to other drivers.

Fix: Paccar will notify owners, and provide a temporary repair until bendix develops a permanent remedy. This service will be performed free of charge. The safety recall began on february 10, 2012. Owner may contact kenworth at 1-425-828-5440 and peterbilt at 1-940-591-4196.

The oil module centrifugal spinner filter cap in the paccar mx engine may become loose, possibly allowing the cap to come off and engine oil to partially discharge from the oil module onto exhaust components.
