Only through your dealer or GM chat. You can ask for a live agent on GM chat but they haven't been giving up much information. If it has a VIN your dealer should be able to track it through Vin View.

Exactly correct. However vin view only works if your vehicle is past order status 3800.

That is a good sign. However, I would ask your dealer to be sure. GM chat is hit or miss on many things.
