RECALL: Thousands of Western Star Trucks Recalled For Second Time Due to Fire Risk

Portland, OR – Daimler Trucks North America (DTNA) announced it is recalling, for a second time, certain Western Star trucks due to a problem in the electrical system that can lead to a fire.

DTNA alerted the National Highway Traffic Safety Administration (NHTSA) of the issue earlier this month, according to documents submitted.


According to DTNA, the recall affects 2017-2019 Western Star 4700, 4900, 5700 and 6900 trucks manufactured between October 18, 2016 and February 6, 2018.

DTNA estimates approximately 7,128 units are affected.

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, increasing the risk of a fire, the company stated.


DTNA was first alerted to the issue in or around March 2018, the company stated, and opened a recall with the NHTSA at that time (Recall #18V-191).

According to NHTSA, DTNA issued an interim notification to owners on May 23, 2018, and the recall began on October 29 of the same year.

Dealers reportedly inspected the power stud for the proper clearance to the bulkhead and replaced — free of charge — if deemed necessary.


Under recall 18V-191, DTNA reported the same 7,128 units were believed to be affected.

However, in or about April 2021, the company told NHTSA it “decided to reconsider the inspect and replace remedy approach given new certain data” and opened a new investigation.

The company said from April to late September 2021, it “analyzed plant quality data, field service information, warranty data, and inspected exemplar vehicles.”


DTNA’s analysis identified the potential that field operator routine maintenance/cleaning using high pressure power-washing equipment could be introducing additional water intrusion risk that was not reasonably foreseen in prior analysis from the 2018 recall.

Therefore, DTNA elected to issue another recall for the same vehicles.

As a remedy, dealers will replace the pass-through power studs, free of charge.

Owner notification letters are expected to be mailed January 9, 2022.

DTNA and NHTSA made clear the new recall supersedes the previous 2018 recall.


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.
