The defect
PACCAR Incorporated (PACCAR) is recalling certain 2024-2026 Kenworth T480, T680, T880, W990, Peterbilt 520, 536, 537, 548, 567, 579, 589, 2025 Kenworth T180, Peterbilt 535, 2025-2026 Kenworth T280, T380 and L770 vehicles. The tail brake light, upper and lower beam headlights, reverse light, and turn signal may not illuminate as intended. In addition, the lift axles, if lowered, may revert to a raised position, or oscillate up and down when the signal warning lights are activated. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 108, "Lamps, Reflective Devices and Associated Equipment."
The risk
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.
