What's wrong
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.
Why it matters
A short circuit increases the risk of a fire.
