What everyone is experiencing is called bump steer. It is a consequence of a stiff suspension, particularly the anti-roll bar.

I have experienced this problem as well. I'm sure when this started happening or if it is normal on this car... but when driving on uneven roads or on roads with ruts in them, the car almost seems to steer itself. I have to keep my hands on the wheel otherwise I'll get into an accident.
