I’ve had the car for 5 years, I’m familiar with how it works.

I did not say that the car uses the brakes to stop. I said that with hold mode, it applies the brakes once you are stopped. Also there is a mode to blend brakes with regen. This is used when the battery can’t accept any energy via regen. Usually when the charge level is close to 100% or the battery is cold. In order to provide consistent dynamics, the car will auto use brakes to make up for low regen.

Here’s the manual for hold mode.
