This probably is nothing to be concerned about but we all know the subtle sounds and idiosyncrcies of our cars.Lately when first driving cold(Ca so 40 to 50s) there is a high pitched whine from drive train area. Decreases substantially after a mile or2.its there in neutral coasting as well as in gear. Coincident with engine rpm. Suspect it's just exhaust system related. Goes away too soon for transmission I suspect because that's not even warmed up. Never totally goes away if u know what to listen for but much less apparent. Probably have to hear for yourself.I suspect emissions exhaust system normal. Any ideas?

Go to the dealer have the rear checked could be the gears are set wrong.
