I've replaced my pads and rotors already but I have somewhere around 37k and I did abuse the pads and rotors. The rotors were very warped and that was a major reason I replaced them.

 

ok.... well i work at a dealer and i see these kind of things happen all the tiime... different cars wear differently... and we only cover up to 12k because fo the way people drive. im not talking crap about you.. im just saying in general... because customers always complain about pulsation.... they arent gonna keep turning rotors if its just gonna happen with the way the person drives. im not saying it shouldnt be under warranty i just know what they are going to tell you.
