Re: Rotors warping
My rotors warped at about 35k kms. The dealer turned them at the time and
I have driven for another 7k and so far they are holding. But in the
meantime, I have retorqued the lug nuts using my own torque wrench and I
try not to brake hard (unless the idiot in front of me decides to)!!

Re: Rotors warping
You didn't hear wrong.
Some places have a grinder for truing up a warp.
I think it probably works better than a turn. A turn can still follow
the warp to a certain point, but more important a turn takes off a layer
of metal. A grind takes off the minimum or just the high spots.
