I know there are a few of these around, but I think this is the best method in terms of materials and longevity.

Total cost of materials used is probably about $0.50 lol.

Essentially, this (or something similar) is what you want to buy: http://www.homedepot.com/p/Project-...x-2-ft-R-5-Insulation-Sheathing-PP1/203553730

I tried this with a few different materials, but a lot of foams will compress over time and the rattle will just come back. If the material is too rigid it'll either transmit the vibrations to the entire deck, or just fall out. This stuff is dense enough to not deform, but still foam-y enough to absorb vibrations and stay put once in.

Materials needed:
- Knife
- Electrical Tape
- Foam Insulation Board

Cut out a wedge from the foam; dimensions are shown in picture. I trust the American friends can use Google to convert:

Wrap the whole thing in electrical tape. This is so you don't get purple shit all over your trunk when you wedge it in, and also it looks far better in black than purple lol. It's important to have the tape in the orientation shown below so it doesn't pull/rip when you wedge it in:

Wedge the wedge in the space between trunk chassis and 3rd brake light:

Here it is, not yet fully in. Play some loud obnoxious music at volumes you wouldn't normally listen to. Keep pushing the wedge in until there's no more. At final position mine is about 75% inside:

Nice. There are so many different fixes users have found on their own yet Honda still hasn't issued an official one.

I just wanted to say thank you for this! I just finished doing this, and turned up the volume, no more rattling, just like how I want it.

Yup - I think the density of the foam is key here; softer foams will deform/compress and become inefficient over time; this stuff won't, and will hold up.

Jam it in further? I park outside in heat everyday when I work and I haven't noticed any change.

Built this little wedge a week ago just as you showed and jammed it in. Worked like a charm!

Can hardly wait to try this. Rattle not heard much from front seat but horrible when sitting in back seat.

Oh my goodness... THANK YOU @inv4zn!!! I bought the foam from the home depot link you provided, cut it to the 70x70x30x10 dimensions, covered it in electrical tape, shoved it up in my 3rd brakelight and VOILA! it works beautifully! The rattle is COMPLETELY gone! Turned the volume up to 30 on Drake's 'Best I Ever Had' (shoutout to your homeland @inv4zn) and the sound system almost made me cry it was so beautiful. Thank you again @inv4zn, let's pray this fix lasts a while! Picture below of the wedge shoved up in there - it truly is the 3rd brakelight making a majority of the rattling.
