2015–2018 Western Star 4900 Recall

Issued March 10, 2017
Issue
Hazard description
On certain vehicles outfitted with triple compartment aluminium air tanks, the end caps of the tanks may have received incomplete welds during manufacturing. If a weld were to separate on the tanks, it would result in a rapid loss of air pressure, which could cause reduced brake performance, or unexpected application of the parking brakes, increasing the risk of a crash causing injury and/or damage to property. Correction: Dealers will replace the affected tanks with triple compartment steel air tanks.
