Bob, you may not have found out what the problem is yet, but at least you can eliminate your 12v battery being defective. Mine read 13.1v at rest and your more extensive test says yours is fine. Still a puzzler as to why your ICE seems to come on excessively compared to the rest of us.

Hi Ken. Today ICE came on twice while driving. Not stopping. Honda is on my case. We will see.

I have not been able to find the voltage of the hybrid battery

The 2018 Honda Clarity Plug-In Hybrid Emergency Response Guide has a section on the Li-Ion battery that reveals the voltage:

High-Voltage Lithium-Ion Battery
In addition to a 12-volt battery, the Honda Clarity Plug-In Hybrid has lithium-ion batteries with a maximum voltage of 352 volts. Housed in a water resistant case, the lithium-ion batteries are stored under the cabin floor. This means that the lithium-ion battery body is normally hidden from view.

Question: Are the batteries actually "stored under the cabin floor?" I believe that all the batteries are collected under the front and rear seats, aren't they? Or could there also be some batteries beneath the floor in front of the rear seat? Perhaps "the cabin floor" is defined as the separation between the battery and the cabin.

ICE issue persists. Happened again over the last couple of days. I forced it once by using the left paddle (-) when I again came to the 3rd stop sign. If this is an issue with the battery pack being unable to accept regen, then why does it not happen with a pure EV car in terms of not being able to accept more "juice"? Reg still works. Probably does with the Clarity EV as well.
 
Just now started out in Sport mode. Hit the - paddle to max chevrons. The computer subtracted one. Hmmmmm. ICE did not come on. The other day, did the same thing, but I forced the paddle to "max chevrons," and ICE came on. Hmmmmm.
 
What I don't agree with is "learn to live with its limitations." It can and should be made better. Or least explain how it works. Another analogy. A mulit-stage rocket. You don't want the stages to fire prematurely.
 
The Clarity of owner A should operate the same way as the Clarity of owners B, C, D … It seems that in this owner's case, his doesn't. While I have no background (except lots of years of ownership for HEVs and PHEVs) I suspect that there might be a temp or speed sensor acting up somewhere in the inverter that's causing his EV to kick out prematurely in favor of HV mode (ICE engagement) Time will tell. Eventually the sensor will fail completely and throw a code.
