I don't know! My car is still under factory warranty and I don't wanna touch it myself to later on givem exuse for not fixing the problem! you know, it's murphy's law!!!! What could go wrong, will go wrong! it's my case! I could not duplicate the problem when I was at the dealership and as you might know, they won't just take your word for it, they have to see the problem themselves. But as soon as I brought my car home, the very next morning, there it was! Oh well, I really don't know what to do!
