I have mine set to the same but I read somewhere in the manual that, even though the car is turned on automatically on entry, the car isn’t in ‘ready’ mode until you press the brake pedal, nothing else just the brake pedal, at which time a car symbol with a left/right arrow underneath appears on the dash screen. I’m therefore assuming that the traction battery isn’t engaged until that symbol appears, and that until that time it’s in ‘accessory’ mode and running off the 12 volt battery only.

I’m certainly interested in the opinion of others about this.
That is also my understanding, that the car is in 'accessory’ mode until you press the brake pedal.

I'd suggest taking your car to an independent garage or a fastfit center and asking for the 12v battery to be checked because I've seen many issues on other car forums (non Honda) where the relevant dealership denies that there's an issue and then many months later with various battery related issues occurring they change it and the issues/faults are no longer evident.
That way at the least you'll know whether or not if there's a problem with the battery.
