If the car feels sensitive to wind gusts, take the car to the dealer for alignment. In my experience, NONE of the indy's have set front toe-in correctly. Dealer has to increase it 2X and then its perfect.
If the car feels like the rear end is steering, you very likely have worn rear links, or something bent, or broken.
If wheels and tires have recently been replaced or rotated, you may have discovered a bent rim or tire with a separated belt. Bent rims CAN be a cause of pulling or a car going crooked down the road.
These cars sacrifice a lot of suspension comfort when something is incorrect. But when everything is correct they are great driving cars.
