Toyota is conducting a safety recall and customer satisfaction campaign (CSC) involving the Toyota Mirai.
Approximately 2,800 vehicles are involved in Japan, the US, Europe, and the UAE.
Under unique driving conditions, such as if the accelerator pedal is depressed to the wide open throttle position after driving on a long descent while using cruise control, there is a possibility that output voltage generated by the fuel cell boost converter could exceed the maximum voltage. If this were to occur, a warning light will illuminate, a message will be displayed on the instrument panel, and the fuel cell system will stop running.
If the fuel cell system stops running, electric power steering and the brakes will function normally. The fuel cell system can be restarted after the vehicle is stopped.
For all involved vehicles, Toyota dealers will update the fuel cell system software at no cost to customers.
