The defect
Kenworth is recalling certain model year 2012 and 2013 T270 and T370 medium duty trucks built with Eaton Ultrashift transmissions between December 7, 2011, and April 6, 2012. The air harness from the treadle valve on the affected vehicles was routed in a manner that can cause the air brake lines to be pinched between the cab and the electronic clutch actuator of the Eaton Ultrashift transmission. Significant movement between the cab and transmission can cause progressive wear and an eventual leak in the air lines.
The risk
Air lines which leak can cause reduced brake function, which may result in a crash.
The remedy
Kenworth will notify owners, and dealers will repair the vehicles free of charge. The safety recall began on November 30, 2012. Owners may contact Kenworth at 1-425-828-5000.
