I would first check to see if the windows are up all the way, and that the doors are closing completely, then make sure the rear hatch is closing tightly.
Also take a look around the tail pipe, you may have backed into something, that would hinder the exhaust gases escaping past the rear bumper.
I think everything should still be covered under the warranty
