Whenever I drive my TSX over road bumps or the radio is on, a buzzing comes from the door panel. I thought I had isolated it to the upper left panel (same panel where the seatbelt comes from). Acura looked at it 3 times now and has put insulation foam inside, but the buzzing is still there. Moreover, they tell me THEY can't hear it, even though I drove with a tech.

Anyone else experience this problem with a post '04 TSX? If so, what was wrong (loose?) and what was the solution?

 

I have an 08 that has buzzed on the driver's side since new. I couldn't reproduce the sound with dealer's technician since the roads around the dealership were so smooth. I told them to try a repair that's done on TL's. They stuck on a special tape around the door's rubber seals as well as inject silicone grease into them. Noise was still there after.
I've tried spraying the rubber seals with silicone spray, but that doesn't work. Opening the window a bit works, but who wants to drive around with a partially open window all the time.
I recently narrowed it down to not the rubber seals nor the pillar around the seatbelt, but to the actual door panel. I would assume that the fix on the 04s have already been applied to the 08s, so I'm not sure how to fix it yet. One person says to loosen some screw. I'll have a closer look once I pull my door panel off to install a new speaker.

 

Hey Nonyo,
After my fiasco to the Acura dealer (who also claimed they put sealant in the door panel), I took it to Honda. They said it was LOOSE CLIPS that were rattling around in there. They put some sealant around them and I haven't had a problem since.

 

I'm glad you got rid of the annoying buzz. Thanks for posting the solution.

Well I am having an Acura 07' and am happy to possess that car. I was driving in heavy rain when all of sudden it experience a gush and buzzing sound. I found out that water has peeped into the engine and it is making a sound. I really had bad experience since the car didn't start even after 2 hours.
