Q rotors last nearly 40,000 miles!
They could be worn (or heat damaged). On my original 1991 Q45, with the high-performance pads, I used to change the rotors every 2 to 3 pad changes (about 32k to 35k miles, as I recall) till they went to a different pad formula. The rotors needed re-surfacing at the second and third (if it went tht far) pad changes and this was enough to drop their thickness a lot.
The G35 has excellent braking characteristics - very reminiscent of the early Q, so it is possible that the rotors do wear sooner than usual.
