Recently my front brakes were feeling like the rotors were warped so I replaced the rotors (R1 Concepts) and the pads (Hawke HPS)on Wednesday. I drove 400 miles this past weekend and the front brakes still feel the same.

So, what else could be causing this problem? I flushed the brake fluid back in May. There doesn't appear to be any air in the system as pressure wise pedal travel is normal.

Did you properly bed them in? Do they still feel warped or what?

Caliper seized up causing the rotors to overheat and warping the rotors very quickly

Yes, I bed them after I first put them on.

The calipers retracted fine when I was installing the new rotors and pads. If one caliper was seized wouldn't the car pull to one side and/or stop poorly?

Not necessarily. These cars are heavy enough and with the the AWD they may not pull unless it's very stuck.

Did the pulsating occur as soon as you used the new brakes? Are your tires properly balanced and wearing ok? Are you rear brakes working? in return making the fronts work too hard and overheat.

I'm not sure how AWD would make a difference in braking when my foot isn't even on the accelerator. As for weight wouldn't the brakes be sized for the extra weight? Otherwise the car would never stop.

The pulsating is just the same as it was with the old rotors and pads. The old pads also had a lot of wear left on them. As for the rears I changed the rotors and pads last May.

Well, I did test today and determined that it's the rear rotors. I went out driving and stopped just using the ebrake. I get the same vibration. New rotors and pads are on order.
