Winter of '12 I slid into a curb and hit both the front and rear passenger side wheels. Afterward the X pulled slightly and wore the edges of the front tires. Took it to an indy for alignment and they were not able to align it after two attempts. I then took it to the dealer who replaced a control arm and it aligned fine. I replaced one wheel because it was cracked (but still held air). For good measure I took it to a different indy for alignment this summer. The alignment was still in spec, though I did have him bring the toe to 0.00. :-)
