Daimler Trucks North America, LLC "DTNA" is recalling certain 2017-2023 Freightliner Cascadia, 2020-2022 Freightliner Business Class M2, and 2022 Freightliner 114SD, and 2020-2023 Western Star 49X, 2021-2023 Western Star 47X, and 2021-2022 Western Star 57X vehicles. The brake modulator valves on the front axle may corrode and cause the vehicle to pull to the affected side during an Adaptive Cruise Control "ACC" braking event.
Brakes that pull to one side during an ACC braking event may cause a sudden change in vehicle direction, increasing the risk of a crash.
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 16, 2023. DTNA's number for this recall is FL-958. This recall expands and replaces previous recall 20V-390. All vehicles previously repaired under recall 20V-390 will need to have the new remedy performed.
Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 'TTY 1-800-424-9153', or go to www.nhtsa.gov.
