I think excessive oil consumption on the RSpec is a problem, but it is not such a problem as to be "actionable" under warranty. You'd need to show consumption at substantially more than one quart/1000mi. to get warranty attention from Hyundai or any other mfg.
My own experience was similar, about a quart every 2K or so. I did pull the throttle body off and mopped up quite a bit (a cup?) of oil sitting on the bottom of the intake manifold. This indicates to me ring blow-by. My auto guru says that rings can seat, unseat and reseat. On longer trips with continuous driving my oil consumption decreased, indicating, perhaps, that rings are seating. My sense is that Hyundai's ring seal is not as good as it can be. I did put an oil catch can in the system, which seemed to reduce oil consumption by better capturing and recycling oil vapors.
