I can confirm this very problem. I just bought the car, pulled off the lot and pulled up to the traffic light and when I hit the brakes it pulled...well, sort of hard, to the left. I thought oh man this car needs an aligment. But during later driving (bought it last night 11/5) I haven't experienced it. Since I just bought the car, I will keep you in the loop if it happens again. I am going to ask the dealer to align and check the braking system anyway, but now that I've read this I cam convinced this is a problem with the IS. I have an IS350 btw.
