Rattles, Rattles Everywhere - Rear Deck Fix?

Don’t get me wrong. I like my ’09 Accord sedan (4 cyl), but the rattles are driving me nuts. I’ve gone through the board posts and done the following:
1 – Rear Shelf Rattles When Vehicle Is on Rough Roads (Service Bulletin 08-083)
2 – Added a plastic tie to secure the wiring harness to the trunk light
3 – Adjusted passenger and rear headrests
4 – Put cloth/rubber shims between the rear shelf (3rd brake light) and rear window
Most of the rattles are gone, but what is still there is a rattle/buzz that comes up when playing the radio. It doesn’t have to be loud, but the bass seems to elicit a buzzing/rattle sound.

The cloth/rubber shims got 60% of this, but the rattles makes the car feel cheap. I called Honda corporate, and they’re researching.

In the meantime, I if I press down on the rear shelf (by speakers and 3rd brake light), the noise goes away. I figure it’s just like Service Bulletin 08-074, but Honda Corporate tells me that’s for 2008 Coupes.

Anyone with an 09 sedan have a fix? How about a Service Bulletin for this (08-074 for 09 sedans)?

Thanks,

Rear deck rattle

I used a thin foam cut out in the shape of the light housing. No more rattle against the glass! Hope this helps

Same here! I put 2 pieces of computer packaging foam between the 3rd brake light but it is a temporary solution.

I discovered a new buzz/rattle today...it's coming from my seatbelt (where it meets the pillar). The only other buzz/rattle I have is in the passenger door on certain music frequencies. It's rather annoying.

Half A$$ Fix

Here's my fix so far... Ghetto.

Rubber feet/stoppers, cut in half length-wise and jammed in 3 places:

1 - between 3rd brake light and window
2 - onsides of rear deck and window

There has to be a more elegant fix. I still get some buzzing from the bass during certain songs. It sounds like it's the deck pieces (upper and inside/lower) rattling against each other.

Honda Corp was very nice and said they'll investigate and see if there's a fix besides the Service Bulletin 08-083 or 08-074 which is for coupes.

What have you guys done to completely eradicate the pesky rattle/buzz?

I know we are pm'ing about this..

but I think your rattles are beyond just the third brake light one... honestly, next step, remove that shelf. everything prone to rattles unveils itself (and theirs a whole heck of a lot if any of the little plastic fasteners of tolerances when the deck was made/installed were not adhered to....it is a Honda, not a VW Phaeton.

Things you can do w/ rear deck out..

1) wrap underside w/ a thin layer of damplifier/sound deadening type stuff..there are spray sound deadening options, but w/ both applications, you want to make sure fastener points and areas that need to be exposed to allow the deck to go back in, stay exposed. some people

2) ace hardware sells black adhesive backed felt ... I used this on exposed metal tips, in between panels that seemed they could in the least bit be prone to contacting each other and along the edges of all the plastic contained in the rear deck.. I honestly think a couple of rolls of this tape should be given to any new owner.

Here's some on amazon..

Amazon Amazon



I only had to do the above steps on my '08 ( that was built in August 07)... my '10 had buffering and felt tape applied in the rear deck...not as much as I would have laid down had I gone to town, but the amount that should have been applied to all 8th gens to begin with (guessing so many service department check in's related to rear deck rattling finally became a nuisance to dealership owners, honda took notice? i dunno)

Some people have utilized that expanding foam stuff meant as a insulator for around the home (spray into crack, seams, etc...expands and dries hard)...I always like to be in control of where stuff is applied, so I personally wouldn't go this route..not saying it doesnt work and actually might be a quicker (and could also prevent the need to remove rear deck if sprayed in certain spaces).

Argh... I am really hoping not to have to remove the rear shelf myself--it looks a little complicated.

Honda Corp called today, and a guy spoke with me about the problems. The only thing they have on record is a service bulletin that has you put felt inbetween a clip (above / inside the trunk where the light is). I told him the stealer did this for me already, and the other day I noticed that the piece of felt fell off!

He couldn't really help beyond that. The other fix for the brake light rattling applies to 08 coupes, and not my 09 sedan.

So tomorrow, I will go to an independent guy who's worked on my Hondas for a long time. Not sure what he can do, but we'll see.

Last resort, I guess I can try to remove it. Keep your fingers crossed.

BTW, do you guys have any remaining rattle/buzz after putting those shims along the rear deck/window? It helps me get rid of say 75% of the noise, but it still bothers me that I get this plastic rattle/buzz when certain bass notes hit.

Thanks again!

Mine is 2011 and that rattling noise just get louder and more often.
I heard someone in this forum talk about a technical service bulletin TSB, and i was thinkin to talk the dealer to talk to them about it.
Has anyone try to bring their car to the dealer to fix this little but frk annoying problem?

They can't fix it completely. I took the car in to get it fixed under that TSB, the noise decreased and happens less often but it is still there. My suggestion is to go get the TSB done to reduce the noise and then follow one of the solutions proposed on the website to get rid of the noise completely ( I haven't followed any of the solutions yet so I can't tell you how well they work)

Turning the bass down should solve the problem.
