I've read all the problems people have with this and know somewhat about it, but mine is a little different i think. Sometimes when I am driving, the light will come on for a few minutes and then go out, car still drives fine and whatnot. After I shut it off if I try to start it, the light will come on and I have to wait a few minutes for it clear and then start the car. I'm using the second key that came with my car, it's basically brand new. Maybe the wiring is bad somewhere in the key hole?
