Just got mine back on Friday. It was out of alignment and my Conti's had cupped in the rear.
Dealer realigned the car and did a side to side rotation to try and even out the wear pattern and take some of the noise out of it. The rotation did help a bit with the noise problem. I could notice the difference in alignment, although it wasn't that far out at the steering wheel before it went in. It does track better now than before it went in. Find a good independent shop if your dealer is short in equipment.
