Joker have you asked to dealer if there are any non published recalls for your vehical? They can run your vin and tell you over the phone. The other thing, I don't remember if this was f o r d or chevy or someone else but I thought that the dealerships had a way of posting a problem to see if anyone had run accross the same thing. Can of a private internet just for dealers. You may want to ask if that is something that they can do for you.
Have you had ANY work done on the car recently?
