Dealer just called. Turbo needs to be replaced, it's falling under an emissions thing, so it's not even going under my warranty. Free of charge. The noise my car was making was the exhaust flex pipe. He said that isn't covered under any warranty because its an exhaust component. He said the dealer can do it for $450 parts and labor, or I can just bring it to an exhaust shop. I guess the dealer replace that whole pipe.
