Hi guys, I am new to this forum. I bought a 2013 white TSX last April. Right now, I am noticing a slight rattle sound on the passenger side of the car if I am driving on a bumpy road. I don't know how common this is, but if you guys have experienced the rattling noise on the passenger side, do you know where the sound is originating from and how I can fix this? Thanks.

 

I thought I had rattles in the passenger side but it turned out to be that top piece with the dome lights and sunglasses holder. I took it apart and added foam on all sides, that fixed the issue.

 

I have a 2012 TSX and when I got over bumps I hear a rattle/squeak from the passenger side too. I think its coming from the seat or the door I can't figure it out.

 

Possible causes
1) Passenger side grab handle
2) Headliner
3) Moonroof rubber seal (against roof chassis)
4) glove box or shelf inside the glove box
5) Windshield trim on A-pillar, from *outside*...

 

Also might be the headrest. Mine rattled. I switched it w passenger side. Sunglass holder rattle is most common i believe.
And cup holder...everything makes noise in those unfortunately.

 

I hear the same rattles on the passenger side of my '09, too. Particularly during cold weather on rougher roads. It *seems* to be coming from either the door or glovebox area but I'll check the sunglasses holder that many mentioned as I hadn't considered that before.

 

I have the exact 2013 acura tsx white in april as well

I heard that kind of noise but it was actually the SEAT BELT!!
It was twisted to the door panel so whenever it goes to bumpy roads, it shakes against the side and makes that noise.

 

I get the sunglasses holder rattle. Trying to ignore it.

 

Easiest way to diagnose sunglass holder rattle is to open it and leave open when you hear it. If it stops, its the closing hinge mechanism thats source of rattle up there

 

I have a 2011 and it came from the passenger seat also. Took the seat out and made sure everything was tight under the sear and put foam insulation where the plastic pieces on the foot if the seats are and bolted it back down. Worked for me.!!

 

oh, let me try that also... but no noises from me now..

 

I think mine is coming from the seat too. Is the seat easy to take off and put back on?

 

I was just about to post the same thing, drove me nuts for a while until I figured it out.

 

I experienced the same thing not too long ago... and I only recently picked up my BWP in December!

 

Not hard to remove and put back at all, bolts and a electrical connector. That's it.
