What is wrong
Daimler Trucks North America LLC (DTNA) is recalling certain 2017-2019 Western Star 4700, 4900, 5700, and 6900 trucks. The affected trucks have a power stud that passes through the bulkhead. In certain circumstances, the power stud may contact the bulkhead and result in an electrical arc.
What can happen
An electrical arc can increase the risk of a fire.
The remedy
Dealers will replace the pass-through power studs, free of charge. Owner notification letters were mailed January 7, 2022. This recall supersedes previous recall number 18V-191. Vehicles previously inspected and considered complete under 18V-191 will need to return for the new remedy. Owners may contact DTNA customer service at 1-800-547-0712. DTNA's number for this recall is FL-907.
