Hey all, my TSX is a month old and I was praying that rattles would not occur. Well, one day I was driving with the stereo off and started to hear rattles when I went over bumps in the passenger side. I started to listen carefully where the rattle noise was coming from and you know where it turns out to be? The seat belt buckle hitting the piller. So i just moved the buckle back into it's proper position and no more rattles.

One thing that does bug me is that whenever someone uses the seat belt, the buckle always faces the piller.

 

My wife, god knows why , likes to unclip the sunvisor when she uses it. It took me several minutes to locate that rattle the first time (the visor tab rattling against its clip).

 

 

Yes, whenever someone rides shotgun I notice that....dang shitty design.

Consider yourself lucky that that is your only rattle.
