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."

PACCAR Incorporated (PACCAR) is recalling certain 2022-2025 Peterbilt 520, 579, and 2021-2025 Kenworth T680 trucks. The high voltage (HV) contactors may open, causing a sudden loss of high voltage and a loss of drive power.

Risk: A loss of drive power increases the risk of a crash.

ELECTRICAL SYSTEM: INSTRUMENT CLUSTER/PANEL

PACCAR Incorporated (PACCAR) is recalling certain 2024-2026 Kenworth T680, T880, and W990 trucks. The 15-inch digital display may fail to display warning lights or vehicle speed. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) numbers 101, "Controls and Displays" and 121, "Air Brake Systems."

Risk: An instrument panel display that does not show critical information, such as warning lights or vehicle speed, increases the risk of a crash.

Risk: Safety systems that depend on the ECU (Automatic Traction Control, ABS, Electronic Stability Control, Active Cruise Control, and Collison Mitigation System) may not function properly or at all, increasing the risk of a crash.

POWER TRAIN:AUTOMATIC TRANSMISSION:LEVER AND LINKAGE:COLUMN SHIFT

PACCAR Incorporated (PACCAR) is recalling certain 2021-2024 Peterbilt 365, 367, 389, 535, 536, 537, 548, 567, 579, and 2021-2025 Kenworth T180, T280, T380, T480, T680, T880 and W990 trucks.
