At about 15k miles, my wife's rotors were warped, and the dealer replaced them w/o charge, and w/o complaint. They made some vague reference to 'problems' with rotors. Now at 40k they're warped again. The car is under warranty still, but I can imagine them blaming the problem on us this time. No heavy duty use of the brakes and when I'm in the mountains I'm particularly careful about downshifting.
I've not yet shown them the car... should I expect reasonably that they replace them again for free?
