The recall affects 2015-2018 Western Star 4900 trucks manufactured between March 3, 2014, and Jan. 31, 2017, that were built with certain triple compartment aluminum air tanks. The company says these tanks could experience weld separation, which could cause “a rapid loss of air pressure without warning.” That could cause a sudden application of the park brakes, increasing the risk of a crash.
The recall is expected to begin April 27.
Daimler says it will notify owners, and dealers will replace the aluminum air tanks with steel, triple compartment air tanks at no cost.
The National Highway Traffic Safety Administration’s number for this recall is 17V-124.
