Hi Stella,
I have a 2020 Honda E, which has just been in to Newton's Croydon today; after my dash lit up like a Christmas tree telling me all the things were faulty starting with brakes. Then parking brake, collision detection, adaptive cruise control, one pedal driving, lane departure mitigation and low speed collision mitigation. After being away for a couple of weeks and going to take the car in for the diag, I found the brakes not to be functioning well... very soft and then a jump where I could then hear the friction brakes being applied, although it was as though it was an old cable style system with no assistance. I'm pleased I was only doing low speeds too!
After going in for a diagnostic today - I was told the control unit is faulty. The cost to replace it is £3048!
I was advised to speak to Honda direct, as they have seen a lot of these units on different vehicles failing. I think we need to get Honda to admit they have a faulty component and have them in for recall, as you said.
Sorry I don't have anything more useful to offer at this point.
