Doesn't hurt to take it in and see if it's covered. If not, I'm sure you can buff that out.
Yeah the way thats peeling looks like something acidic was poured on it because of the direction its peeling. Even so it wont be covered under warranty most likely. It doesnt look like factory clear coat failure but more like some like industrial fallout got on it since its near the roof. All I know is that infiniti is very strict with covering cosmetic defects not caused by the manufacturer.
