I have a 2006 6spd GTO and am experiencing a couple of anomallies. At times when I strike a bump the radio will come on. Then a couple of times when accelerating agressively, while turning, the steering column will lock! Disconcerting to say the least. As soon as I back off on the accelerator the steering unlocks? The only commonality I can find is in the electrical controls in the steering column and the ignition switch. Problem seems to be post minor fender bender, car turned into left front fender, and the bumper skin and left headlight were replaced. I'm in Canada and as the model was never sold here there are few resourses such as manuals. Wondering if anyone else has experienced momentary column lock or has any insight. Thanks.
