I feel the same way with my car but it is pulling right. I have about 10k miles on it and the dealer is saying it is my tires. I am going to have them replaced soon, but I think 10k is too soon for the tires and the car is never going straight but always pulling.

I had it re-aligned as well and had the entire suspension checked, but the active steering never came to mind.
