2020–2027 Western Star 49X & 2021–2027 Western Star 47X recall: electrical system
⚠️ 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.
💥 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.
Is the fix free? Yes. Safety recall repairs are free at any authorized dealer under federal law, including parts and labor. (Vehicles more than 15 years old when the recall was announced can be excluded, but most manufacturers still fix them.)
