Hey everyone, I’ve been driving my EV6 GT and recently started noticing a screeching sound, especially when braking. I’m at 20,000 miles and wondering if this could be worn brake pads already. Has anyone else experienced something similar? Do EVs tend to wear out brake pads faster? I’d appreciate any insights or advice on whether I should get them checked now. Thanks!
If you’re using regen for braking, the rotors will get a little surface rust. Just use your ‘regular’ brakes from time to time, and that will burnish the rotor and make your brakes quiet like they’re supposed to be.

Hmm 
You likely shouldn’t have pad wear at 20k miles, but it could be normal corrosion on the discs, especially if you use strong regen settings. Probably just need to set regen to 0 and do some hard braking to clean off the discs.

I use auto regen.

When you set regen to 0, it uses the friction brakes instead of regen for the first few times you brake. That’s why people recommend it to clean the rotors.
This happens to me with auto regen too. When it does, I turn regen off completely and use the brakes more often, and that clears it up. Like others have said, it’s probably just surface buildup because you don’t use the brakes as much with regen. I notice it more on humid days when there’s condensation on the rotors after sitting in the garage overnight.
Agree with everyone else—it’s likely not worn-out brake pads but a result of auto regen. You can clean the rotors by setting regen to 0 and using the brakes for a while. There’s also a small chance it could be something like a stone or small piece of metal stuck between the pad and rotor. Any repair shop or dealer can easily check that out, and many places don’t charge for it.
