The two times my Crossfire did "it" the spoiler went up and had to be manually lowered. I felt like an idiot in the bank line with my spoiler up. So far it hasn't happened again but I am having the same issue with our '04 Mercedes. They are replacing a steering angle sensor next week which I hope clears up the problem. No I'll affect on performance but its nerve wracking to my wife who drives the car.
