It seems that in the morning, my HV battery drops pretty quickly within the first few minutes of driving, and I'm suspicious of the 12v losing charge overnight and leaning on the DC-DC converter in the mornings. It's possible I may have some kind of small parasitic drain. Or it might be my imagination. Tested the voltage and it was about 12.8v which seems good for a 12v resting.

Since it's Honda branded, maybe I should take it into the dealer for testing? Will the warranty on the 12v battery carry over if I'm not the original owner?
