Defect
The electric water pump that cools the fuel cell system uses motor magnets with an inadequate surface treatment, allowing coolant to corrode the magnets. As corrosion progresses, the electric water pump ceases to operate. This may cause warning lamps and warning messages to illuminate when power mode is engaged and prevent the fuel cell system from starting, or, during driving, cause warning lamps and warning messages to illuminate and shut down the fuel cell system. In the worst case, the vehicle may become inoperable.
Corrective action
On all vehicles, replace the electric water pump with a corrected part.
