Daimler Trucks North America is recalling 450 Western Star 4900 vehicles because a defect with the aluminum air tanks could increase the risk of a crash.

The truck recall includes 2015 to 2018 versions of the truck manufactured between March 3, 2014 and Jan. 31.

The affected vehicles are equipped with triple compartment aluminum air tanks. The welds on these air tanks could separate and quickly lose air pressure. As a result, the parking brakes may not function properly, which could lead to a collision.

“A rapid loss of air pressure without warning may result in reduced braking ability or application of the park brakes potentially increasing the risk of a crash,” the National Highway Traffic Safety Administration said.

No crashes or injuries related to this issue have been reported.

The defect may be the result of “incomplete weld penetration, porosity or misalignment of  end caps during assembly,” according to the recall report.

Dealers and truck owners will be notified of the issue in April.
