If you drive the car hard, the wheel will not stay centered after alignment. The EPS coupler in this car is made of play-doh and failed hopes and dreams.
For the last couple years mine would be fine after an alignment, but after a hundred miles or so the wheel goes off center 10-15 degrees even though the car tracks just fine.
