Navistar, Inc. (Navistar) is recalling certain model year 2011-2012 Workhorse W62 Commercial Chassis manufactured June 21, 2010, to October 2, 2012. In the affected vehicles, the weld joining the right hand side exhaust down pipe to the exhaust manifold may fatigue.
A failure of the weld may allow hot exhaust gases to enter the engine compartment, increasing the risk of a fire.
Navistar will notify owners, and dealers will install support brackets on the right and left hand exhaust down pipes and a catalyst spacer bar to prevent swaying. Any cracked down pipes will be replaced. These repairs will be performed free of charge. The recall began on November 17, 2014. Owners may contact Navistar customer service at 1-800-448-7825. Navistar's number for this recall is 61401-C.
