Just called my dealer's service manager, pads are not covered. Rotors are not covered unless there is an obvious defect in the rotor. Calipers likewise are covered only if defective (ie cracked or leaking), fluid is not covered. When I asked him about a stuck piston on a caliper with third party (non-OEM) pads... the answer was... No the pads, rotors and calipers and fluids would not be covered. Your answer may vary.
