What's wrong?
The 2017-2018 Honda Clarity Fuel Cell uses an electric water pump to move cooling water through the fuel cell stack. That stack makes electric power for the drive motor, and it needs steady cooling to stay within its operating range. The pump's rotor spins inside the pump body, with magnets helping drive that rotation.
On included vehicles, the magnets attached to the rotor core inside the electric water pump were not properly surface-treated. Water exposure can corrode those magnets, and the corrosion can crack them. Once the rotor core is damaged, the pump stops moving coolant the way it should. The fuel cell system then protects itself by reducing power or shutting propulsion down.
The warning sign is a "Power System" warning light or message on the multi-information display. The vehicle then enters EV limp mode or loses motive power, so treat that warning as a reason to stop in a safe place and arrange dealer service.

What happens at the repair
At the dealer, a Honda technician replaces the water pump covered by recall 19V315. The repair addresses corrosion inside the pump that can lead to pump failure. Replacement parts and labor are free under the recall. Out-of-pocket repairs already paid are handled through the new vehicle limited warranty, not through a separate reimbursement program, because Honda says that warranty covered this problem without owner payment. Ask the Honda service desk how warranty coverage applies if prior repair paperwork exists.
