07 Es350 Rear Brakes

[Tom33]

I purchased this car from a private party and had a dealer do an inspection. It had 30,950 miles. The report showed a timing cover oil leak, which will be fixed under warranty tomorrow and a notation that rear brake pads should be replaced soon "due to 3mm inside pad". I notice a slight pulsating when the brakes are applied and suspect a warped rotor. I will have this inspected also tomorrow. I recall seeing a comment on this board or another one, that a warped rotor was a warranty item. Does anyone know if this is true? If it is and the uneven brake pad wear is on the same wheel, should the warranty include replacing the pads?
