## What is wrong

Mack Trucks, Inc. \(Mack\) is recalling certain 2019 Mack Anthem trucks equipped with Jost fifth wheel couplings.  The fifth wheel may have an outboard slider bracket that is too narrow, possibly allowing the trailer to separate from the tractor.


## What can happen

If the trailer separates from the tractor, it can increase the risk of a crash.


## The remedy

Mack will notify owners, and dealers will inspect the fifth wheel slider bracket, replacing it as necessary, free of charge.  The recall began September 25, 2018.  Owners may contact Mack customer service at 1\-800\-866\-1177.  Mack's number for this recall is SC0411.
