    Hello,

    I understand how a noise can be annoying especially after you go searching for the source. Please let me know if I can be of assistance.

    Safe travels,

    I suspect a heat shield under the floor, under the hood. Look at the exhaust.

    Seeing as the truck is under warranty (I assume you have less than 36K miles), let the dealer fix the problem.
