Unfortunately, there is no way on car, Honda Link app, or any Honda web site to check and see that there are any Open Sefvice Bulletins for our Claritys that I know of.
You can use your VIN to check for recalls on both Honda and Govt sites but these are only for safety related major issues.
However, sometimes people report a new update is available (got by buying a subscription to Honda Tech??) and even less often will report they were notified by Honda of one. I’ve never been notified by Honda a depend on this forum to know when to have my dealer install them. One Canadian owner (lorem101, 10/5/18) has posted a notice he got on his Honda Link about a “campaign ID” on the water valve problem.
Be forewarned, many have reported that their dealer was reluctant to install them or even check do them. And that some flat out lied to keep from doing it by saying it wasn’t for your VIN (when SB said for all VINs) or its already updated (when it wasn’t). It seems you will have a better chance of success if you go in with the Service Bulletin numbers in hand and prepared to counter their BS.
Fortunately I have a good dealer who couldn’t find them in his computer, but cheerfully looked up the SB #s I gave him and said no problem, we can have it done in an hour.
I wish Honda had a better system for handling Sevice Bulletin updates.
Here are some information and posts I’ve gleaned from this forum:

EVTC Failure Misdetection: SB 18-089
HV Range Display: SB 18-091 (seems different from the one others reported)
Abnormal water temperature reading: SB 18-090. For this one, they ordered a part and said it will take several hours and they would have to disassemble the entire dashboard.
In my case, the service advisor went to his computer, looked up my car by vin and said: you have 4 product updates available.

It appears that the fix for the DTC P26A3 is now a software update mentioned in Service Bulletin 18-089, dated 10/4/2018. I was told that this Service Bulletin supersedes Service Bulletin 18-079. Another Service Bulletin, 18-090, calls for the replacement of the Climate Control Unit. I suspect that this may also be related to problems with the heating water control since the issue corrected is described as coming up when running the heater. These two Service Bulletin updates are to be done at the same time along with a new software update, 18-091, to correct the HV mileage issue. All three (3) Service Bulletins are part of a recall campaign for the affected Clarity automobiles.

Yesterday (10/4/2018), my wife had another Multiple Systems Warnings episode. This time I was not there to reset things so I decided to call the dealer and get the fix (TSB 18-079) and well as the HV mileage update (TSB 18-069). The service adviser was surprised at my call as just a few minutes earlier, he was given notice of a recall campaign to fix these (and a couple of other) issues. I had the software updates done this afternoon (10/5/2018) and got paper copies of the four (4) relevant Service Bulletins:
18-089: EVTC & 3-way Valve software update for DTC's P100C, P0010, and P26A3 (this replaces 18-079)
18-090: Climate Control Unit Replacement
18-091: Driver Display Software Update (Mileage) (this replaces 18-069)
18-096: Warranty Information CD
The parts were ordered so that the service needed for 18-090 and 18-096 could be done in a future visit.
All the Service Bulletins are dated 10/4/2018 except for 18-091 which is dated 9/21/2018. The four mentioned Service Bulletins are all lumped together (all mentioned in all Service Bulletins) and the owners all affected vehicles (determined by VIN) will be sent a notification of the campaign.

PS: They also installed service bulletins 18-090 and 18-091, and ordered parts for 18-089 and 18-096.
Hope this is helpful info for you.
