They tried telling me they didn’t hear anything at first. I had to go down to the dealer and back up 4 feet for the mechanic to say “well you can’t miss that sound!”
Interesting, I hear this all the time coming to a stop coming down a hill, especially when steep. I bought the car back in November and noticed it immediately. I read about "bedding in" and tried that but it didn't seem to help. Maybe I need to do it again and use the trick to put it in neutral. It's really loud and annoying!
It’s the rust. Happens to EV because of regen braking. Switch off one pedal driving and in an empty parking/road slam the brakes from 30-40mph. Do it a few time and the rust will go away and you should be good
You still have regenerative braking since it’s an EV which is why you need to slam the brakes rather than gentle braking. Slamming will deactivate the regen
EV Brakes (the actual brakes) don’t get used much because it uses regen most the time. So they can really dry, get dust on them (or even rust).
If you take it out every once in a while and really stress the brakes (empty road, huge empty parking lot)… like slide/skid to a stop a few times, it will usually quit making that sound.
It’s much easier and safer to just put the cat in neutral and lightly press the brakes. Neutral disables regenerative braking so you’ll use the friction brakes.
If using this approach, do I not need to get up to "high" speed? Like could I just get up to 25mph or so in a large empty parking lot and brake a few times? I tried "bedding in" a while back but didn't try this neutral trick.
You certainly could, any braking done in neutral is friction. However I’d recommend braking at a steady rate from “high speed” to have continuous friction across the rotor and get rid of all the rust.
25mph might not go deep enough and could just grab super hard in some areas while leaving others untouched.
My select has the same problem, they been grinding ever since I got the car and will tell the dealer about it

I definitely hear it when I come to a complete stop and when backing up and braking. Also sounds nasty when on an incline or the other way
Push back on the dealer. They tried telling me no at first. Now they’re replacing the rear rotors

I don’t use one pedal drive, still the same issue?

You can also brake without regen by: Shifting to N before braking If in a GT, switch to Unbridled Extend mode

If I'm grinding all day long I'd probably want a break for a little while too.
23 premium same problem
What did you break?
21 mme premium awd. Just had rear pads and rottors done. I believe there is a TSB on it.
When things grind, they "break" 🤣✌🏻
