Paccar is recalling 5,731 Peterbilt and Kenworth trucks because a defect in the spotlight circuit could start a fire.
The recall affects 2013-2017 Peterbilt 567 and 579 Kenworth T680 and T880 vehicles produced between Jan. 25, 2012 and Dec. 14, 2016.
The affected trucks are equipped with optional spotlights that help increase visibility under certain conditions. The problem is that the spotlight circuit may not be sufficiently protected in the event of a short, according to the National Highway Traffic Safety Administration.
“A short in the spotlight circuitry may increase the risk of a fire at the cab fuse block,” the NHTSA said.
Several fires have already occurred and some trucks were damaged by “overheating and melting located at fuse box,” the recall report said.
The source of the issue is still under investigation, but to fix the problem mechanics will replace the optional polyfuse switch in the spotlight circuit with a standard fuse.
The recall is expected to begin Aug. 31.
