Paccar is recalling over 50,000 trucks to fix two different issues.

A total of 56,575 Peterbilt and Kenworth trucks are being recalled for problems with their headlights, brake lights, and turn signals. There also is an issue with the trucks' lift axles.

In affected trucks, the tail brake light, upper and lower beam headlights, reverse light and turn signal may not illuminate sufficiently. Additionally, when the signal warning lights are on, the lift axles may revert to a raised position when lowered or oscillate up and down.

The National Highway Traffic Safety Administration recently announced the recall saying, "Delayed and unsteady headlights can result in insufficient illumination of the road, decreasing the driver's visibility and increasing the risk of a crash. In addition, an unexpected position change of the lift axles may increase the risk of injury."

Kenworth trucks covered by the recall include:

• L770 (2025-26)
• T180 (2025)
