It turns out it was a defective caliper. Hydraulic issue would not let the pistons retract completely, which would drag the pads ever so slightly, causing heat, and the warping the rotor.
Only after doing a spin test on each caliper, did we figure it out. Take off one caliper, spin the wheel and count the rotations, and then do it again on the other side. It was quite obvious after that what was the problem.
