Driving home from a trip had fiberglass start coming out of the muffler(see pic). Never in my life have I had this happen with a car of mine.

I have an appointment at the dealership to see if it's covered by warranty. But, I can't find muffler anywhere in the warranty.

Car has 56k miles on it, am I wasting my money at the dealership to check?

EDIT: Forgot to say this is a 2022 Trailblazer RS

EDIT 2: Called dealership after back and forth they put me on with an advisor who told me muffler aren't covered after 3 year 36k. So they were in fact, trying to milk me for a diagnostic charge.
