    Dec 13, 2021

    Daimler Trucks North America, LLC (DTNA) is recalling certain 2020-2022 Western Star 4700, 2019-2022 Freightliner 114SD, 2021-2022 Western Star 49X, Freightliner Cascadia P4, 2022 Western Star 47X, 2021 Western Star WF110, 2020 Western Star WJ121, and 2019-2021 FCCC XCP Chassis vehicles. The fuel tubes between the fuel rail and the injectors for cylinders four, five, and six may fatigue and crack, which can result in a high pressure fuel leak.
