What's wrong?
The fuel pump on the 2014-2015 Honda GROM125 and NSS300 moves gasoline from the tank to the engine. Inside the pump, a small spinning impeller pushes fuel through the system so the engine gets a steady supply. That pump has to keep the impeller clear and turning while it sits in fuel.
On these motorcycles and scooters, a plastic resin part inside the Spec-C fuel pump was exposed to test oil before the vehicle went into service. After long-term exposure, the resin inlet cover can swell. Once it swells far enough, it presses against the impeller and the impeller seizes, stopping the pump from delivering fuel.
There is no warning sign before failure. The engine can lose fuel supply without a prior light, noise, or change in how the motorcycle feels.

What should I do?
- Check your VIN to confirm your 2014-2015 Honda GROM125 or NSS300 is included in this recall.
- Contact a franchised Honda dealer to schedule the free fuel pump assembly replacement that prevents the swollen internal bracket from seizing the pump and stalling the motorcycle.
- Reference recall number 16V661 and Honda recall KC3 or KC4 when you call.
- Bring the recall notice and ask the Honda dealer to confirm whether a motorcycle repaired under recall 14V-672 needs the fuel pump replaced again.
- Ride cautiously until the repair is complete, and pull off safely if the motorcycle stalls.
What happens at the repair
At the dealer, a Honda technician replaces the fuel pump assembly with a new assembly that uses a metal bracket inside the pump. The dealer repair is available now, and parts and labor are covered under the recall. This recall also includes some motorcycles repaired under recall 14V-672, so a prior repair does not settle the question by itself. If you've already paid for a related fuel pump repair, Honda has a general reimbursement plan on file for documented expenses. Ask Honda customer service or the dealer service desk how to submit repair paperwork.
