The creaking sound (like a metal to metal) I could hear coming from driver side rear door area had got me quite wound up for a while (weeks). Below freeway speeds, I could hear the sound when going over slight imperfections on the road..couldn't really diagnose without sitting on the rear seats. It turned out to be the metal finish around the windows was rubbing just enough on the white painted surface during movements to cause this sound. I could reproduce by simply moving that piece just a little, by hand. I could have applied some paint polish in there, but I had handy the trusted WD40 and used a drop to let it flow down that area (in the pic) - and gone was that annoying sound!! Yay! In case this helps one other owner a more peaceful driving . Cheers.
