14V056000 · Engine And Engine Cooling
Reported: 2014-02-14 (February 14, 2014) · Model years: 2013
Honda is recalling certain model year 2013 CB500 (FA, F, XA, X) and CBR500 (RA, R) motorcycles. The rocker arm shaft retaining bolts may have been manufactured incorrectly resulting in the bolts loosening during engine operation. A loose bolt will initially result in a slow leak of engine oil, but if not addressed, the bolt can come out of the cylinder head entirely.
Consequence: Without a bolt, the engine will have reduced power which may result in a stall, increasing the risk of a crash.
Remedy: Honda will notify owners, and dealers will replace the rocker arm shaft retaining bolts, free of charge. The recall began on March 11, 2014. Owners may contact Honda Customer Service at 1-866-784-1870.
NHTSA campaign record ↗21V690000 · Service Brakes, Hydraulic:Antilock/Traction Control/Electronic Limited Slip | Service Brakes, Hydraulic
Reported: 2021-09-02 (September 2, 2021) · Model years: 2019, 2020
Honda (American Honda Motor Co.) is recalling certain 2019-2020 CB500X and CBR500R ABS motorcycles. Excessive grease in the ABS modulator may collect debris, which can get stuck in the check valve and cause a brake fluid leak.
Consequence: A brake fluid leak can reduce braking performance and increase the risk of a crash.
Remedy: Dealers will inspect the lot number on the ABS modulator, and replace the modulator as necessary, free of charge. Owner notification letters were mailed November 12, 2021. Owners may contact Honda Powersports customer service at 1-866-784-1870. Honda's number for this recall is KM6.
Reported: 2021-05-24 (May 24, 2021) · Model years: 2020, 2021
Honda (American Honda Motor Co.) is recalling certain 2020-2021 Super Cub C125, CB500X, CB650R, CBR300R, CBR500R, CBR650R, Rebel 300, Rebel 500, Monkey, 2020 CRF250L, GROM, 2021 CRF300L, and CB500F motorcycles. 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.
