I have had a somewhat similar problem. And it ended up getting worse and worse. I think it is connected to stage 2. GM has told me that nothing is wrong, but I know that something is up, so I have contacted the BBB. Hopefully I will get some results from them.

Those are links to a few threads I started when trying to get to the bottom of the problem(which I still havnt done yet). Maybe the advice in those threads will help..
