I doubt rotors are covered but it's worth a shot. I know, I know, "bumper to bumper" should be what it sounds like it is, but parts considered "wear parts", i.e. brakes, filters, wiper blades, etc. generally are not covered. We had to fight tooth and nail to get the rotors replaced on our 09 at less than 20,000 miles. You're at the end of your warranty period, even less of a chance.
