Thanks everyone for the warm welcome!
Thanks for the invite Shane. I am in NH but have some friends in CT so end up down that way quite a bit. Unfortunately I can't make it that weekend.
Now that I've looked closer at the wheel, it seems more like pitting from the aluminum under the chrome than a chip. There's several other spots as well that are actually raised bumps on the chrome, all of then on the inside surface of the spokes. I'll see if GM will do anything under warranty. I can only imagine it will get worse as it sees more NH winters.
