I read in the manual that "mechanical adjustments" are under warranty for 12,000 miles or 1 year.
My question is if an alignment is covered?
My car goes straight, but the steering wheel is turned to the right to do it. If i force the steering wheel straight, it pulls hard to the left.

 

was it like that the day it left the dealership in your hands?
then no- you may have hit a pothole or curbshot it or something happened to alter things, something may even be bent!! have it checked at an alignment shop

adjustments means the headlight aim or a hood needs a nudge to sit perfect on each side, a wiper arm,,,,, small fitment problems is what they mean
Also covers squeeks and rattles in the dash and rear deck
