I tend to have a suspicious nature after dealing with dealerships and quality issues for a large part of my life. Now it makes more sense. If the noise is disappearing after its warmed up and never comes back until its restarted next morning then I suspect its a minor repairable problem. Maybe the oil filter as some have suggested here. I went through a few potential components that could make a noise like you discribed just so you would have some ammunition when you went back to the dealer.
