Its been discussed before. I think if I remember its the sealed coolant system gassing/venting off.

Thank you. Just drove the car both easy and hard and put it back in the garage and noise is gone. I'm wondering though is this normal or do
I have to bring it in for service?

Yes, it has been discussed a few times, but I'm not sure anyone came back with a definitive answer. IIRC, all the threads just died out with a few assumptions left hanging.
