3 distinct campaigns affect this selection. Announcement dates below are different from vehicle model years. A campaign may cover multiple years.
Reported: 2014-10-27 (October 27, 2014) · Model years: 2014
American Honda Motor Co. (Honda) is recalling certain model year 2014 GROM125 motorcycles manufactured June 12, 2013, to September 24, 2014, and 2014 Forza-NSS300, and NSS300A motorcycles manufactured June 18, 2013, to May 21, 2014. The resin bracket inside the fuel pump of the affected motorcycles may swell and cause the pump impeller to seize.
Consequence: If the fuel pump seizes the motorcycle will stall, increasing the risk of a crash.
Remedy: Honda will notify owners, and dealers will replace the fuel pump with an updated fuel pump, free of charge. The recall began on December 15, 2014. Owners may contact Honda customer service at 1-310-783-2000. Honda's number for this recall is JL1 NSS300 (Forza) and JL2 Grom (Grom125).
NHTSA campaign record ↗Reported: 2016-09-14 (September 14, 2016) · Model years: 2014, 2015
Honda (American Honda Motor Co.) is recalling certain model year 2014-2015 Grom 125 motorcycles manufactured June 12, 2013, to September 8, 2015, and 2014-2015 NSS300 & NSS300A motorcycles manufactured June 18, 2013 to March 19, 2015. The resin bracket inside the fuel pump of the affected motorcycles may swell and cause the pump impeller to seize.
Consequence: If the fuel pump seizes, the motorcycle will stall, increasing the risk of a crash.
Remedy: Honda will notify owners, and dealers will replace the fuel pump assembly with one that uses a metal bracket internally, free of charge. The recall began October 2016. Owners may contact Honda customer service at 1-888-234-2138. Honda's numbers for this recall are KC3 and KC4. Note: This recall supersedes recall 14V-672. Some, but not all, motorcycles that were remedied under that campaign are affected by this recall as well and need to have the fuel pump replaced again.
NHTSA campaign record ↗Reported: 2021-05-24 (May 24, 2021) · Model years: 2020
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.
