Mack Trucks, Inc.: Trailer Hitches › Fifth Wheel Assembly
Mack Trucks, Inc. reported this defect to federal regulators on Oct 13, 2015 and put the number of vehicles at risk at 448. The repair is free for as long as the recall stands.
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.

What this page is, and what to do next
A recall is not an opinion. It is a Part 573 report a manufacturer is required by federal law to file once it decides a defect poses an unreasonable risk to safety, and it commits them to repairing the vehicle at no cost to the owner. The three passages above are the manufacturer’s own wording as published by NHTSA.
This page describes the campaign. It cannot tell you whether one particular car has already been through the shop — that is tracked by VIN, and only the manufacturer knows it. Check yours at nhtsa.gov/recalls or with a franchised dealer, quoting campaign number 15V644000.
