## What is wrong

Daimler Trucks North America, LLC \(DTNA\) is recalling certain 2023 Western Star 4900 and Western Star 6900 vehicles.  A defect in the inversion valve may delay park brake engagement, which could allow the vehicle to move unintentionally.  As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 121, "Air Brake Systems."


## What can happen

Unintentional vehicle movement can increase the risk of a crash or injury.


## The remedy

DTNA will inspect and replace the inversion valves, as necessary free of charge.  Owner notification letters were mailed February 27, 2024.  Owners may contact DTNA customer service at 1\-800\-547\-0712.  DTNA's number for this recall is FL992.
