Recalls, owner-reported complaints, investigations and safety data

Owner complaintsComplaints are reports submitted to NHTSA by owners and drivers. NHTSA does not verify most reports before publishing them, and a complaint does not establish that a defect exists. Volume is influenced by how many of a vehicle were sold, how long it has been on the road, and how much attention an issue has received.
0
Safety recallsA safety recall is issued when a manufacturer or NHTSA determines that a vehicle has a safety-related defect or does not comply with a federal motor vehicle safety standard. Recall repairs are free. Whether a specific vehicle is covered depends on its VIN — a recall listed for a model year does not necessarily apply to every vehicle of that year.

InvestigationsNHTSA opens an investigation to examine whether a safety defect may exist. An open investigation is not a determination that a defect exists, and many investigations close without a recall. Investigations can, however, lead to one.

Crash or fire reportedComplaints whose submitter recorded that a crash or a fire occurred. These are the reporter's own answers on the NHTSA form, not verified findings.

EXTERIOR LIGHTING:LIGHTING CONTROL MODULE:SOFTWARE

Jun 26, 2025
56,260 units potentially affected
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.
The remedy: Dealers will update the VCU software, free of charge. Owner letters were mailed August 19, 2025. Owners may contact Kenworth's customer service at 1-425-828-5888 and Peterbilt's customer service at 1-940-591-4220. PACCAR's number for this recall is 25PACF.

ELECTRICAL SYSTEM: INSTRUMENT CLUSTER/PANEL; EXTERIOR LIGHTING:HAZARD FLASHING WARNING LIGHTS:SWITCH; EXTERIOR LIGHTING:LIGHTING CONTROL MODULE:SOFTWARE

Jan 29, 2025
5,378 units potentially affected
The defect: PACCAR Incorporated (PACCAR) is recalling certain 2025 Kenworth T180, Peterbilt 535, 567, 2025-2026 Kenworth T280, 2023-2026 Kenworth T380, 2024-2026 Kenworth T480, 2024-2026 Peterbilt 536, 537, and 548 trucks. The exterior lighting switch may fail, resulting in the hazard lights and the instrument display back-light brightness adjustment not functioning. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) numbers 101, "Control and Displays" and 108, "Lamps, Reflective Devices and Associated Equipment."
The risk: Inoperative hazard lights cannot alert other drivers as intended. In addition, the inability to adjust the brightness on the instrument panel display can make it difficult to see critical safety information or distract the driver. Both scenarios can increase the risk of a crash.
The remedy: Dealers will update the vehicle cab controller unit (VECU) software, free of charge. Owners are advised that a non-responsive switch can be temporarily reset by a key cycle. Owner notification letters were mailed March 26, 2025. Owners may contact Kenworth's customer service at 1-425-828-5888 and Peterbilt's customer service at 1-940-591-4220. PACCAR's numbers for this recall are 25KWB and 25PBB.
