Figured out where the leak is.

So we took a bucket of water and while I sat inside the hubby poured it in different areas.
We found that it looks like one of the drains for the sunroof is not working right.
You can tell that it isn't the sunroof itself because of the places where the water is coming in.
So he will call the dealer tomorrow about it.
Kinda sucks, we have had the vehicle less than 3 weeks and it is already going in for repairs.

The drain tube(s) probably aren't installed properly. Good thing those GM employees made $70/hr to build your vehicle.
