What is wrong
PACCAR Incorporated (PACCAR) is recalling certain 2017-2020 Peterbilt 520 vehicles. Due to undersized wires, the connector between the cab power harness and the power distribution center (PDC) harness may overheat and melt, possibly resulting in an engine shutdown.
What can happen
An unexpected engine shut down can increase the risk of a crash.
The remedy
PACCAR will notify owners, and dealers will replace the main power wire to the PDC with a wire of the correct size, free of charge. The recall began August 6, 2019. Owners may contact PACCAR customer service at 1-918-259-3258. PACCAR's number for this recall is 19PBB.
