Warped rotors?

Hey all,

I have a 2018 330i with 6.5k miles on it. Began to realize that you hear the brakes rumbling between 65-80mph. It hasn't gotten to the extent that it shakes the entire car yet, so if the music is loud enough, it's not particularly noticeable.

Are warped rotors covered under warranty this early? I know BMW removed brakes/rotors from maintenance, but this doesn't seem like regular wear and tear to me. I generally don't do too much spirited driving, and don't slam on my brakes so I'm a bit confused

It is unlikely that YOU can warp a 25 mm rotor. More likely you have deposited pad material stuck and making high spots.

What Doug said. You need to do a few "panic stops" to remove any pad deposits that have accumulated.

Very unusual for factory pads to leave deposits, they are incredibly abrasive and scrub the rotors well. If you can feel the shake, you've got a braking performance issue. Car should be under factory warranty. Complain to dealer when several aggressive stops from 70 - 0 MPH don't fix it.

Aggressive stops from 70 MPH to 5 MPH. Do not leave the pads resting on a stinking hot disc.

The rotors may also have developed a glaze which gives a shuddering sensation. Doug's remedy should work.

I tried the 70-5 a few times. Still feels a little uneven but its pretty bearable now

I've had this a few years back, I took the rotors and cut them. Problem solved.
