Details
What's wrong: 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.
Why it matters: 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.
