Tires and Wheels problem
2010 Nissan Armada V8 All Wheel Drive Automatic 5100 miles

I got the car aligned to try to prevent the tires from wearing down prematurely due to shipping/delivery, etc. It was found to be very out of alignment, so they aligned it, next morning the steering wheel turned even with the car going straight, re-alignment showed it was out of alignment again, so they aligned again, happened one more time....just looking to see if anyone has had a problem like this before? Just got the car Nov. 2009 and only has 5100 miles on it....please help, I don't know what to do....
