The problem
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.
The risk
A loss of power can increase the risk of a crash.
The fix
Honda has notified owners, and dealers will update the FC-ECU software, free of charge. The recall began February 14, 2019. Owners may contact Honda customer service at 1-888-234-2138. Honda's number for this recall is A3O.
