The 2017 Honda Clarity Fuel Cell has 3 recalls, all tied to the same core risk: the vehicle can lose power or stall unexpectedly, raising the risk of a crash.
Two of the recalls involve the fuel cell control unit misreading a minor drop in cell voltage and cutting power to the drivetrain, either partially or completely. An earlier software update intended to fix this did not fully resolve the problem, so some vehicles that were already repaired under that remedy remain affected. The third recall covers a water pump whose internal components can corrode and fail, which can also cause the vehicle to stall while driving.
