On my RWD M3, I noticed that I can hear the brakes on the front of the car dragging a bit. I took a look and there's a clear difference on the rotors as a result of this. I'm sure it's nothing serious, and just that the pads are dragging a bit so they just need to be cleaned up a bit. But I'm a little disappointed about the rotor surface being as it is. Does this kind of thing get covered by warranty? I can certainly take apart the brakes myself, I just didn't want to bother with it if this is covered in the warranty. But it's so hard to get anyone from tesla on the phone, so I figured I'd ask here if anyone had experience with it.
