In a letter to the NHTSA, American Honda Motor Co. describes the defect as such: “A resin bracket inside the fuel pump may swell and interfere with the impeller which may cause the fuel pump to stop working properly. While parked, this can present the engine from starting. While riding, particles may become stuck between the bracket and the impeller causing the engine to stall and possibly not restart.”
Honda began initial investigations into the issue in June 2014, receiving reports from Thai Summit Mtisuba, the manufacturer of the component, through subsequent months. By October 15, 2014, Honda determined that a safety defect exists and decided to initiate the recall in North America. According to the defect notice submitted to the NHTSA, “as of October 3, 2014 Honda has received 30 warranty claims and no injuries related to this issue.”
Owners of affected models will be contacted via mail with a request to take the vehicle to a Honda motorcycle dealer. The dealer will replace the fuel pump, free of charge. Owners may contact Honda Customer Service at 1-310-783-2000, using recall number JL1 NSS300 (Forza) or JL2 Grom (Grom125).
Owners may also contact the NHTSA through the website, www.safercar.gov, or by calling 1-800-424-9153. The NHTSA campaign number is 14V672000.
