Plain-English summary

Daimler Trucks North America is recalling approximately 26,960 Western Star 47X and 49X commercial trucks from model years 2020 through 2027. The defect involves a stud that connects the battery to the starter at the frame rail. This stud may have been incorrectly installed during manufacturing or may corrode over time.

If the stud is loose or corroded, it can fail to maintain proper electrical contact, causing a short circuit in the 12V/24V/48V electrical system. A short circuit increases the risk of a fire.

Owners of affected vehicles were notified by mail on May 22, 2026. The remedy is free repair by authorized Daimler dealers. Owners can contact Daimler Trucks North America customer service at 1-800-547-0712. Daimler's internal reference number for this recall is F1029. This recall replaces and expands a previous NHTSA recall number 25V326; vehicles already repaired under that previous recall will require the new remedy as well.
