The short answer
NHTSA received PACCAR Incorporated’s report on Jan 29, 2025. Copied from NHTSA on Oct 28, 2026.
Every line below is in NHTSA’s own words, with its source beside it.
What’s wrong with it?
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.
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.”
