You need a front wheel alignment alright, I never buy a new car without recieving the wheel alignment printout.
I make the dealer do a wheel alignment, they charge you a delivery fee so make them earn it. The statement that its done at the factory might all well be true but its what happens to the vehicle by the time you get thats the problem.
And you should keep an eye out on your tyres, that sort of wear would be noticeable in the first 500 miles and you could have taken it back to the dealer and asked for a wheel alignment. If there is no visable marks or scratches on your wheels the dealer would do it under warranty.
