To make the noise go away, I tweaked the upper door frame ever so slightly inwards and the noise went away (knock on wood). Don't know if that is the same noise as yours, but it sounds like it.
i need to do a lot more research on this problem. the problem is: my wife doesn't hear it! and i'm the only one who drives this car although it's a CVT so she should (she is paranoid about doing something dumb with my/our new car...sigh)
anyway, i did another experiment yesterday and i do think it's in the headrest itself or something in the seat...i had the seat tilted back (laying as flat as possible) and the sound moved to further away from me while driving, so i don't think mine is the door latch/lock. (but i'll keep that in mind)
the next step will be to remove the headrest to see if it goes away.
the problem (and again good thing, too) is that the problem is intermittent. it's only there when the car is cool. after being in the sun a little bit, it goes away...
