An official CAA Japan notice concerns Passenger cars (Honda CLARITY) - Repair. Defect in the cooling system (electric water pump). ■ Defective component: Cooling system (electric water pump). ■ Condition of the structure, equipment or performance considered noncompliant with standards, and its cause: Improper surface treatment of the drive motor magnets in the electric water pump that cools the fuel cell system may allow the coolant to corrode the magnets. Continued use may therefore cause corrosion to progress and the electric water pump to stop operating. Warning lights and warning messages then illuminate when power mode is turned on, and the fuel cell system fails to start. Alternatively, warning lights and warning messages may illuminate while driving, and the fuel cell system may shut down, potentially making the vehicle unable to run in the worst case. Published 2019-04-18.
What to do now
(Recall) ４４８８ ■ Corrective measures: Replace the electric water pump with a modified part on all vehicles.
