NHTSA #23V377000EXTERIOR LIGHTING:HEADLIGHTS

Received: 01/01/2021▼

Defect Description

Ducati North America (Ducati) is recalling certain 2020-2023 Panigale V2 motorcycles. The dashboard could automatically switch from low beam headlights to the headlight daylight position lamp (DRL), in automatic setting mode. As such, these motorcycles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 108, "Lamps, Reflective Devices, and Associated Equipment."

Safety Hazard / Consequence

Lights that automatically switch from low beams to the daylight position can reduce visibility during night riding, increasing the risk of crash or injury.

Factory Remedy & Repair Action

Dealers will update the dashboard software, free of charge. Owner notification letters were mailed June 29, 2023. Owners may contact Ducati customer service at 1-888-391-5446. Ducati's number for this recall is SRV-RCL-23-003.

Manufacturer Notes: Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.nhtsa.gov.
