Recall history
5 distinct campaigns affect this selection. Announcement dates below are different from vehicle model years. A campaign may cover multiple years.
26V500000 · Steering: Steering Wheel/Handle Bar | Steering:Critical Fasteners
Reported: 2026-07-30 (July 30, 2026) · Model years: 2017, 2018, 2019, 2020, 2021, 2022, 2023, 2025, 2026
Honda (American Honda Motor Co.) is recalling certain 2017-2023, 2025 CMX500, 2017-2023, 2025-2026 CMX300, and 2025 Honda SCL500 motorcycles. The handlebar lock screw may loosen and detach.
Consequence: A detached screw may lodge between the frame and stem, interfering with steering and increasing the risk of a crash or injury.
Remedy: Dealers will replace the lock screw and apply thread lock, free of charge. Owner letters were mailed September 29, 2026. Owners may contact Honda's customer service at 1-866-784-1870.

NHTSA campaign record ↗19V412000 · Power Train:Manual Transmission
Reported: 2019-06-04 (June 4, 2019) · Model years: 2018, 2019
Honda (American Honda Motor Co.) is recalling certain 2019 CB300R, 2018 CBR300R, 2018 CRF250L, 2018 CRF250L Rally, and 2018-2019 CMX300 motorcycles. The circlip, on the transmission's main shaft, may detach allowing for gear misalignment.
Consequence: A misaligned gear can shift the transmission from neutral into gear during engine start, potentially resulting in unexpected motorcycle movement or seize the transmission and rear wheel while the motorcycle is in motion. Both conditions increase the risk of crash or injury.
Remedy: Honda will notify owners, and dealers will replace the transmission main shaft, free of charge. The recall began July 8, 2019. Owners may contact Honda customer service at 1-866-784-1870. Honda's number for this recall is KK3.
NHTSA campaign record ↗21V382000 · Exterior Lighting

The rear reflector lens may not reflect brightly enough. 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."
Consequence: A dim rear reflector may reduce the visibility of the motorcycle to other drivers, increasing the risk of a crash or injury.
Remedy: Dealers will replace the rear reflector, free of charge. Owner notification letters were mailed July 7, 2021. Owners may contact Honda customer service at 1-866-784-1870. Honda's number for this recall is KM3.

Emerging complaint spikes
Complete months in the latest six months with at least 10 complaints, at least twice the preceding 12-month average, and at least three square-root deviations above that average.
This is a descriptive screening rule, not a statistical defect finding. Publicity and reporting changes can increase submissions.
No complete months meet the spike thresholds for this selection.
Equal-age model-year comparison
Model-wide cumulative reports during the first three or five calendar years, starting with the model year (age 0). Only fully elapsed windows are compared.
2022: 0 complaints · 2023: 1 complaints
