EXTERIOR LIGHTING:HAZARD FLASHING WARNING LIGHTS

NHTSA #26V645000

Reported October 5, 2026 · Motor Coach Industries, Inc

Potentially affected: 683 vehicles

Defect description

Motor Coach Industries (MCI) is recalling certain 2018-2026 buses. Please see the complete list of models above. The instrument panel indicator light may not illuminate when the hazard warning lights are on and the master run switch is in the 'Off' position. 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."

Safety consequence

Without the illuminated reminder, the driver may fail to turn off the exterior lights when no longer needed. Hazard warning lights that remain activated unintentionally can confuse other drivers, increasing the risk of a crash.
