The defect
Mack Trucks, Inc. (Mack) is recalling certain model year 2011-2014 Pinnacle (CHU and CXU) trucks manufactured September 10, 2010, to June 17, 2013. 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.
The remedy
Mack will notify owners, and Fontaine dealers will replace the fifth wheel with an Ultra NT model fifth wheel, free of charge. The recall began on November 18, 2015. Owners may contact Mack customer service at 1-800-866-1177. Mack's number for this recall is SC0395.
