2020 Freightliner Cascadia Recall

On a small number of trucks, the recall repairs completed by an DTNA service facility during recalls FL958 and FL966 (Transport Canada recall nos. 2022-626 and 2023-051) may not be effective. As a result, another repair is required. On certain trucks, a software problem may not detect corrosion to the brake modulator valves. As a result, the brakes on one wheel could fully apply during automatic braking. If this happens, there could be a brake pull that can cause the truck to change direction. Note: This problem doesn't affect the service brakes.

A brake pull that causes the vehicle to change direction suddenly can increase the risk of crash.
