They told me that the bolts used in the roof are a single-use type of bolt that are made out of plastic. Repeated hot and cold causes them to expand and contract and eventually loosen up. You may notice you hear less noise on hot days because the single-use bolts have expanded. The dealership fix was to replace all the single-use bolts with regular/metal bolts. This cleared up. about 95% of the noise. the care is so much better now.

Only reason I sold the car was when insurance fixed the car at some ****ty garage after a minor accident which led to more problems.
