What the notice says today
The defect
Daimler Trucks North America, LLC (DTNA) is recalling certain 2020-2023 Freightliner Cascadia and 2022 Western Star 49X vehicles previously repaired incorrectly under recall numbers 23V073 or 22V817. The brake modulator valves on the front axle may corrode and cause the vehicle to pull to one side during braking initiated by Electronic Stability Control (ESC) or Roll Stability Control (RSC).
The consequence
Brakes that pull to one side may cause a sudden change in vehicle direction, increasing the risk of a crash.
The remedy
Dealers will replace the brake modulator valves, free of charge. Owner notification letters are expected to be mailed November 8, 2026. Owners may contact DTNA customer service at 1-800-547-0712. DTNA's number for this recall is F1039. Vehicles repaired under the prior recalls will need the new repair completed.
