Rotors warped after about 22K miles, had new brakes and rotors installed at 25K. Thought this was ABSURD! Dealer "did me a one time favor" and covered this under warranty for $100. This car has light-weight aluminum alloy front rotors with a layer of iron over that. The problem is they only last 25 to 35K miles and you must replace both to the tune of $600 ~ $700. Seems absolutely crazy to me. This is a luxury car not a race car for the track. Beware of extra costs if you want to buy one of these cars.
