Daimler Trucks North America is recalling more than 164,000 model-year 2017-2021 Freightliner Cascadia tractors. The single brake modulator valve may be affected by chemical corrosion, which can slow down the release timing and cause the brakes to pull to the affected side during automatic braking events.
Brakes that pull to one side during automatic braking events may cause a sudden change in vehicle direction, increasing the risk of a crash.
