Congrats on your new car. A couple of things. Make sure you check your tire pressure. The cars are pumped to 60 psi overseas to prevent flat spots during shipping -- and a lot of dealers don't bother to set them correctly.
Regarding your problem -- take your steering wheel and turn it full right -- then look at the left front spring -- then repeat by turning full left and checking the right front spring. These cars are shipped with blocks in the springs -- I think they're red in color -- and your dealer may not have removed them during prep.
Since this is the only car Pontiac dealers sell that are brought in by boat -- a lot of them just don't have the experience to prep them right. If nothing's in there -- I'd play it safe and have them check it out.
