The defect
PACCAR Incorporated (PACCAR) is recalling certain 2015-2021 Peterbilt 320 and 520 vehicles. The steering column support structure may crack or break in certain right-hand, stand-up drive models.
The risk
If the steering column loosens from the mounting structure, steering control can become affected, increasing the risk of a crash.
