Daimler Trucks North America is recalling 7,128 heavy-duty trucks because of an electrical system defect that could spark a fire.
The recall includes certain Western Star 4700, 4900, 5700 and 6900 trucks, model years 2017 through 2019.
In affected vehicles, the power cable between the stud and bulkhead – the metal structure located at the back of the cab that protects the driver against shifting cargo in the event of a collision – could make contact, resulting in an electrical arc.
“Arching of a power cable between the stud and bulkhead could increase the risk of a fire,” according to the National Highway Traffic Safety Administration.
Affected truck owners are expected to be notified on May 21. Repairs will be performed by Daimler-authorized service facilities if a defect is found.
