4 recalls across 3 model years
The Honda Clarity Fuel Cell has 4 recalls covering 2017-2019 model years, with the most serious being a fuel cell control unit defect on 2017-2018 models where the system misreads a voltage drop and cuts power partially or completely while driving, raising the risk of a crash.
Recalls 1 and 2 both trace to the same underlying fuel cell control unit fault on 2017-2018 vehicles, with the second recall issued because an earlier software fix did not fully resolve the problem for some 2017 models. The power loss can be partial or total, affecting the driver's ability to maintain speed or control in traffic. The 2017-2018 years also have a separate water pump issue: internal corrosion can cause the pump to fail, which can stall the vehicle unexpectedly. On 2019 models, a rear seat belt locking mechanism may not engage properly in a crash, leaving rear occupants less restrained than the belt is designed to provide.
