What is wrong with some Grand Prix (1998) ignitions? The ignition barrel won't turn all the way to the "Off" position to remove the key. Maybe it will after trying it for 5 to 10 minutes. Seems to be worse in the winter time. I suspect this may have been a recall issue that the previous owner did not follow up on, because I've heard a few other people talk about it. I had the steering wheel internal lock pin replaced, and that didn't do anything. What should I have replaced instead?

Thanks for your participation in advance.
