Why on Earth would you lemon law a car out for that?
Not trying to be rude but this problem is a simple to fix stop using their crap brake pads.
The brake rotors are not being warped it is called a lack of parallelism, and it happens from uneven pad material on the rotor surface.
You need a more aggressive brake pad they went for comfort and this is the result of it. The brake pad is baking its material in the rotor surface this is normal, but it is happening at a level too high. This is causing high and low spots on the rotor surface.
Do I have a recommendation for a brake pad for this vehicle no I do not, but I am sure plenty of people do especially guys who have tracked this car. You can buy high quality replacement front rotors on RockAuto for 75 bucks that's the expensive option you can get ones for cheaper. You can also get replacement brake pads that are probably better than the factory ones for $50.
The other vehicle I have destroys its rotors because the brake pads are so aggressive. The brakes are phenomenal but you will be doing a brake pad and rotor replacement every time, and if you drive it hard they can wear out pretty quick. That car went for aggressive braking versus comfort.
