Hello all. Have had my 2013 GS for about a month. About a week or so ago, I started noticing a sound coming from the B pillar on the driver's side. It rattles when I go over uneven pavement or bumps. And the same area makes a 'tic' sound if I brake or accelerate suddenly. It tried holding the seatbelt adjuster and it doesn't make the sound go away. Anyone else noticed it or fixed it somehow?
