Same issue. I honestly have a list of 15 things that I’ve tried that haven’t worked. Just took it to the service center and they spent 4 hours of “goodwill” time trying to identify the source and failed.
did they not find anything? when my car was sound deadened while still stripped, it was fairly rattle free in the back. but noticed after re-installing my rear trunk lid cover, some rattling re-appeared when going over bumps. i broke some clips while removing the cover and am using some generics that may be slightly too short. when i hit the cover it definitely bumps the trunk lid and isn't flush. give your cover a few taps, and see if it's secure.
No, they didn't find anything. I sound deadened the trunk lid cover and I hear the same amount of noise whether my rear seats are up or folded down so I do not think the source of noise is coming from the trunk. This is why I still think it may be something related to the rear deck.
No because I wasn’t able to fully remove it on my first attempt. However, I’ve driven without the rear seats, side bolsters, trunk lid cover, c pillar and the entire trunk trim so by process of elimination I think it has to be the rear deck if the rattle/buzz is coming from inside the cabin like it sounds like it is.
Good strategy! My passenger side dash and/or door speaker rattles like the dickens on my one mile ride out of my neighborhood on what I call purposely rough asphalt streets. Then, on regular concrete or asphalt, it does not rattle. My wife says to ignore it, but it bugs the crap out of me. What did you do to your speaker to get rid of the rattle?
Same here. What did you do to resolve the rattle? I thought maybe spraying expandable foam in there would help, but my wife wouldn't let me.
