I own a 2010 Prius and I've had to replace the brake pads more often than a regular car because of this, around every two years or 20k miles. I've had to replace the brake rotors twice over 80k miles, as the pads rusted and then wore it down unevenly.
Below 5mph the brakes are used, but it doesn't seem to be enough. Compared to my ICE car they always look a lot worse, and after parked for a day when it's damp have surface rust.
As another comment says, it seems like a software change could fix it by using the physical brakes more. I believe the issue is they get wet, and then don't get hot enough to dry out before parking.
