One thing on the previous posts: The smoke is thick and white; it's not like steam that dissipated in the air quickly, so it's not a coolant leak, I'm fairly sure. The smoke is thick and hangs around; coolant leak smoke vaporizes fairly quickly.
Thanks for input.
Im trying to get the warranty straight; perhaps we can have it checked once we get the warranty Xfered.

It sounds like a coolant leak to me. Coolant produces a dense smoke that lingers just as you described. In fact, I have seen cars with coolant leaks leave trails of white clingy smoke behind them at they drive down the street. The smoke stays like a jet trail on a blue sky. Coolant also has a characteristic smell to the smoke, had to describe, kind of a sweet odor, once you have associated it with a car with the problem you never forget itl. My advice - keep a close eye on the coolant level to see if it drops. Finally, I have read posts in other forums that talk about some problem with the aluminum piston head cracking in early models, gm has extended the warranty to a 100,000 miles on that issue.
