I think someone had a similar issue on ClubGP and it turned out to be something with the BCM. IIRC. Unfortunately I cant help as I havent had this problem, yet. Everything else I have though.
i wouldnt worry about it. shit used to happen to me every so often so i would just turn the car off and on and it would go away, if it didnt on its own. When you say all the time do you actually mean all the time? If so then something might be up.
