Notice how the differential is not horizontal to the chasis. There's also a spot on the right that looked like rubbed against other metal.

I'm going to take the car to the dealership this week since they are not open today. Will keep posted.
Your diff bolt is broken and that means your bushing are most likely worn and you need to change them. I broke my diff bolt 5 times on the 3rd time is when I notice the bad bushing was causing it to break. After the 5th time I got really pissed and I installed Turner Motor Sport Solid Aluminum Race bushing no more diff bolt breaking ever again

take a look

Your Stealership should cover this under warranty, since its your first time.
