My first 530xi had its rotors replaced at 7000 miles, and now my 550i rotors started warping back at 4500 miles. I am pretty sure I should be getting more life out of them without warping.
I've done the bedding in process on these, but it's not going to change the warped issue. I know they'll be replaced for free by BMW, but it's such a pain in the sack to keep going through this.
Anyone else having these issues or is it just me? Maybe it's just me who is warped?

Only two possibilities causing this:
1) A brake caliper piston (the part that squeezes the pad toward the rotor) is dragging and not fully retracting, which causes heat - this is solved with a caliper rebuild. But generally this would happen to only one rotor at a time, not two or four. Are ALL your discs warped?
2) Loose nut behind the wheel, riding the brakes without realizing it.
