The problem

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.

The risk

A short circuit increases the risk of a fire.

The 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.
