   Trailer Hitches / Fifth Wheel Assembly

   Defect, in the NHTSA record

   Mack Trucks, Inc. (Mack) is recalling certain model year 2011-2014 Pinnacle (CHU and CXU) trucks manufactured September 10, 2010, to June 17, 2013.

While continuing to research the scope of the issue, Mack expanded the recall on November 18, 2014 to include certain model year 2008-2009 and 2013-2014 CHU, CXU, GU and TD vehicles manufactured from June 16, 2009, through July 8, 2011.
