Hazard
Honda (American Honda Motor Co.) is recalling certain 2017-2018 Clarity Fuel Cell vehicles previously repaired under recall 18V-068. The previous software remedy may have been incomplete. As a result, the fuel cell control unit (FC-ECU) may misinterpret a small cell voltage drop, causing the vehicle to have a partial or complete loss of power.
