All engines will create some soot, but it is usually unnoticeable. Excessive soot, is an indication there is something wrong, especially on a new car.

There are two likely causes for this.

1. Un-burned fuel - there may be something wrong with the fuel injection system causing it to run very rich and the engine is not able to burn all the fuel going into it. This would be light soot with smell of fuel.
2. Oil is getting into the exhaust - in this case, you would see blueish smoke while the engine is running. The soot would have a oil feel and would smell of burned oil.

Since you are seeing faint white smoke, I would suggest the fuel is not being burned completely. This can be caused by a cylinder not firing, a fuel injector stuck open, a faulty sensor telling the computer the engine is lean, etc.

You need to take it to the dealer and let them diagnose and repair this under warranty.
