Greetings, I've been reading the forums for about a month now but just joined since I just purchased a sunset red premium SL two weeks ago. The problem I am having started about a week after delivery where I believe a clicking noise is coming from the passenger seat wherever the road is not smooth (which is everywhere in Houston). It sounds like the sound of marbles hitting each other. It's not constant but enough to aggravate me. I think it's the seat since I never hear it when I have a passenger. Any suggestions that I can easily look into would be great or i'll drop it off at the dealership at the next service. Thanks and this is a GREAT website.
