The defect
Paccar Incorporated (Paccar) is recalling certain model year 2012-2013 Peterbilt 579 and 587 trucks manufactured February 14, 2011, to December 5, 2012 and 2011 Kenworth T700 trucks manufactured September 21, 2010, to October 1, 2010. The affected trucks are equipped with Fontaine Ultra LT Fifth Wheel connectors, which, due to cumulative damage to the fifth wheel and its locking mechanism, have a locking mechanism that may fail to operate or to properly engage.
The risk
If the fifth wheel and locking mechanism are sufficiently damaged, the locking mechanism may fail to operate as intended and the trailer may unexpectedly detach from the tractor, increasing the risk of a crash.
