A loss of power can increase the risk of a crash.
Summary
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.
Remedy
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.
Notes
Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.safercar.gov.

i-HDS Diagnostic Software and J2534 Reprogramming Software
Honda J2534 Pass-Thru User Guide
Honda J2534 Pass-Thru Software Download
Vehicle Communication Interfaces (VCI)
The i-HDS software supports the use of a generic pass-thru VCI that is compliant with SAE J2534-1 and J2534-2. However, Honda recommends the Denso DST-i or the Bosch MVCI for use on Honda and Acura vehicles, as Honda has worked closely with these manufacturers to ensure their hardware and our software interact safely and within the J2534-1 and -2 specifications, for both diagnostics and reprogramming. If you choose to use a generic VCI, please carefully consider the customer and technical support options you will receive from your chosen device supplier. Honda does not provide technical or customer support for generic VCI devices.
The VCI Application Table below lists devices that either are approved and supported by Honda or are known to have completed and passed an independent, exhaustive validation program with our i-HDS software suite.
