What's wrong

PACCAR, Incorporated (PACCAR) is recalling certain 2021-2023 Peterbilt 579 vehicles equipped with MX-13 engines and 160-amp alternators.

Consequence

A damaged alternator cable increases the risk of a fire.

Remedy

Dealers will replace the frame fastener and secure the alternator cable, free of charge. Owner notification letters are expected to be mailed August 11, 2023. Owners may contact Peterbilt's customer service at 1-940-591-4220. PACCAR's number for this recall is 23PBD.
