SERVICE BRAKES, AIR:ANTILOCK:MODULATOR

Issued by Daimler Trucks North America, LLC · Reported Feb 10, 2023 · 70,167 vehicles affected

What's wrong

Daimler Trucks North America, LLC (DTNA) is recalling certain 2017-2023 Freightliner Cascadia, 2020-2023 Western Star 49X, 2021-2023 Western Star 47X, and 2022 Freightliner 114SD vehicles. The brake modulator valves on the front axle may corrode and cause the vehicle to pull to the affected side during braking initiated by Electronic Stability Control (ESC) or Roll Stability Control (RSC).

Consequence

Brakes that pull to one side may cause a sudden change in vehicle direction, increasing the risk of a crash.

Remedy

Dealers will inspect and replace the front brake modulator valves, as necessary. Some vehicles will have a software update which will alert driver when a replacement is required. All repairs will be performed free of charge. Owner notification letters were mailed beginning October 13, 2023. Owners may contact DTNA customer service at 1-800-547-0712. DTNA's number for this recall is FL966.
