Many of us have had the ticking, including myself. Simply removing and reinstalling the wheels and torquing (with a torque wrench) the lugs seems to eliminate the ticking.

I think it is from incorrectly torqued lugs, which cause the rotor hats to warp/flex.

No one has 100% confirmed what it was, but R&R the wheels seems to fix the ticking most of the time.
