2017 Honda Clarity Fuel Cell: Recall Alert

2017 Honda Clarity Fuel Cell

Vehicles Affected: Approximately 470 model-year 2017 Honda Clarity Fuel Cell electric vehicles

The Problem: Electronic control unit software responsible for monitoring voltage in the fuel-cell stack may misinterpret a minor voltage variance and erroneously shut down the fuel stack in response, which could result in an unexpected loss of motive power, increasing the risk of a crash.

Honda noted that there have been no associated reports of crashes or injuries. The automaker advised that, if the vehicle experiences this issue, a warning message will appear on a screen below the speedometer, indicating "Power System Problem. Stop Driving When Safe." If this warning appears, owners should stop the vehicle in a safe location off the roadway, as soon as possible; the vehicle can continue driving for a very short time using electric power from the onboard traction battery, the duration depending on the battery's current state of charge.

The Fix: Dealers will update the ECU for free.

What Owners Should Do: Honda will begin notifying owners in late February. Owners can call the automaker at 888-234-2138, the National Highway Traffic Safety Administration's vehicle-safety hotline at 888-327-4236 or visit to check their vehicle identification number and learn more.
