Welcome to the site!
With only 53 miles, I'd take it into the dealer if your accessory belt is making noises. Without more information on the type of noise and hearing it for myself, I would probably assume that's abnormal and would be diagnosed for free and covered under warranty.
Regarding the headlights.... I'd take it in and have the dealership look it over and replace. headlights with excessive condensation should be replaced under warranty.
