Danger Due to Faulty Cab Step Prompts RECALL of Thousands of Peterbilt 579s

Bellevue, WA — PACCAR Incorporated has announced the recall of certain Peterbilt 579s due to a partially unsecured cab step that can unexpectedly move while entering or exiting the truck’s cab.

PACCAR alerted the National Highway Traffic Safety Administration (NHTSA) of the issue on January 18, according to documents submitted.


According to PACCAR, the recall affects 100% of the 2022 Peterbilt 579s equipped with chassis fairings manufactured between February 15 and November 1, 2021.

The bolts that hold the chassis fairing step assembly did not have a torque retention feature to keep them tight, PACCAR explained.

The defect allows a latch to become loose and may fracture the rib it was fastened through, causing the fairing assembly to flex, thus increasing the risk of injury, PACCAR stated.

In total, 3,511 vehicles are affected.

PACCAR indicated not all models of 579s are equipped with chassis fairings; however ALL variants of fold out chassis fairings for the updated model 579 are affected.


As a remedy, dealers will add new fasteners and a bracket, free of charge.

Owner notification letters are expected to be mailed by March 19, 2022.

Vehicle owners who have already incurred costs to obtain a remedy for the problem addressed by the recall in advance of receiving notification may seek reimbursement through PACCAR’s process outlined in the general reimbursement plan.


Owners may contact Peterbilt customer service at (940) 591-4220.

PACCAR’s number for this recall is 22PBA.
