A loss of power can increase the risk of a crash.
NHTSA Campaign Number: 18V068
Components ELECTRICAL SYSTEM, HYBRID PROPULSION SYSTEM
Potential Number of Units Affected 471
Honda (American Honda Motor Co.) is recalling certain 2017 Clarity Fuel Cell vehicles. The fuel cell control unit (FC-ECU) may misinterpret a small cell voltage drop, causing the vehicle to have reduced, or a complete loss of, power.
Honda will notify owners, and dealers will install a software update, free of charge. The recall began February 28, 2018. Owners may contact Honda customer service at 1-888-234-2138. Honda’s number for this recall is R0L.
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.

Safety Recall: Fuel Cell Stack – Power System Problem Message is Displayed
|2017||Clarity Fuel Cell||ALL||Check the iN VIN status for eligibility|
The fuel cell stack generates electricity to power the vehicle through a process that combines hydrogen from the fuel tanks and the oxygen from the air. The stack is made up of many individual cells that act like batteries. Each of these cells is monitored individually by the vehicle so if there is a problem with the fuel cell, a warning message appears on the dash before the fuel cell shuts off. Because of a software issue, the monitoring system may shut down the fuel stack at the same time the message appears, resulting in an unexpected loss of motive power, which reduces vehicle control and increases the risk of a crash.
Owners of affected vehicles will be sent a notification of this campaign.
Do an iN VIN status inquiry to make sure the vehicle is shown as eligible.
Some vehicles affected by this campaign may be in your new or used vehicle inventory.
Failure to repair a vehicle subject to a recall or campaign may subject your dealership to claims or lawsuits from the customer or anyone else harmed as a result of such failure. To see if a vehicle in inventory is affected by this safety recall, do a VIN status inquiry before leasing it.
Update the FC (fuel cell) system with the i-HDS.

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.
|Manufacturer||Version Information||Notes||VCI Name|
|DENSO||2.00.0010*||04.04||This is the current generation VCI used by Honda and Acura dealers. Honda routinely validates the functionality and provides customer support for this device.||DST-i|
|Bosch||3.01.54*||04.04||This is the previous generation VCI used by Honda and Acura dealers. Honda routinely validates the functionality and provides customer support for this device.||MVCI|
|Drew Technologies||1.7.7**||04.04||This company has completed an independent i-HDS validation and claims it to function with the i-HDS software. Honda does not provide ongoing validation, nor customer support for this device.||MongoosePro Honda|
