Defect: Daimler Trucks North America (DTNA) is recalling certain 2020-2027 Western Star 49X and 2021-2027 Western Star 47X vehicles. A stud connecting the battery to the starter at the frame rail may have been incorrectly installed or may corrode, which can cause a short circuit.
Risk: A short circuit increases the risk of a fire.
Fix: Dealers will repair the studs, free of charge. Owner notification letters were mailed May 22, 2026. Owners may contact DTNA customer service at 1-800-547-0712. DTNA's number for this recall is F1029. This recall replaces and expands NHTSA recall number 25V326. Vehicles already repaired under the previous recall will need to have the new remedy completed.

Technical service bulletins are repair instructions manufacturers send dealers for known issues. Unlike recalls, the fix is not automatically free — but naming the bulletin at the service desk can save diagnosis time and support goodwill repairs.
