Our 2020 Model Y makes a rubbing sound anytime you are accelerating or decelerating, and when going over bumps. The noise is coming from where the seats meet in the rear. If we separate the seats by a bit, they seem OK. If someone is seated in the back, the noise is not there. Seems to be a rubbing sound from between the two sections (where they meet). Anyone had any luck addressing this, and how? Thanks.
