Does anyone experience a loud fluttering sound seemingly coming from the driver's seat belt at high speeds with the T off? It sounds like the seat belt strap snapping repetatively against the place where it comes out of the pillar behind your head. Upon turning and looking while driving(yikes), I'm beginning to think that it's NOT the strap. Almost like it's something inside the interior panels slapping around. The passenger side doesn't make this sound and the design of the car is the same on both sides so I'm lost. Thanks......
