Plain-English summary

PACCAR Incorporated is recalling certain 2021-2023 Peterbilt 579 vehicles equipped with MX-13 engines and 160-amp alternators. A fastener on the front spring bracket may have been installed with the head positioned on the outside of the frame rail, rather than the correct orientation.

This improper installation can cause the fastener to chafe and damage the alternator positive cable over time. A damaged alternator cable increases the risk of an electrical fire.

The recall affects approximately 4,967 vehicles. Owners will receive notification letters beginning August 11, 2023. Dealers will replace the frame fastener and secure the alternator cable at no cost to owners.

Owners should contact their Peterbilt dealer or PACCAR customer service at 1-940-591-4220 with questions. The PACCAR reference number for this recall is 23PBD. For additional information, owners can contact the National Highway Traffic Safety Administration at 1-888-327-4236 (TTY 1-800-424-9153) or visit www.nhtsa.gov.
