Hi all, Lately I've been stumped on finding where this noise is coming from. I especially hear it when I go over speed bumps/dips. I've searched all over the web at the possibility of it. I think it is coming from the rear seatbelt area. I want to ask for some help. Anybody experiencing the same issue or maybe guide me where the noise is coming from/how to fix it? I have a 2017 Model S.
