Removed all the trim and replaced the brake light. Then banged the panel around and it still seemed to rattle.

Gonna pull the front panel off after I pick up some new bulbs for the plate.

Some sound deadening mat will help if you have panels that are rattling. You don’t need a lot, or expensive stuff either.

So the first owner of my Dad’s BRZ (who only owned it for 1 month and ~800 mi) had the dealer install the factory spoiler onto it. When they drilled the holes the shavings fell into the trunk structure and made rattling noises whenever the trunk was opened. We used a magnet to fish most of it out and that magnet now lives under the padding on the trunk to keep the panel magnetized to keep what remains from moving.

Now that I am thinking about it I am really confused that this worked because I am 90% sure the BRZ’s trunk is made of aluminum which isn’t magnetic.

I have a 2009 Accent hatchback and have had to take the interior hatch trim apart twice now to replace license plate bulbs (weirdly you have to do it from the inside 0_o).

I’ve broken the clips on the very fragile left/right trim pieces that go on either side of the glass, so my car doesn’t have any at the moment...

A garage also had to take some of the interior trim off to fix $1300 CAD in damage when I hit some ice and backed into a guardrail at 50kph in January 2015.

Long story short....both rattle now. I’m used to it and it gets better when the temperature warms up in the spring/summer when everything expands just a bit, but I’m of the opinion that if you take it off once and you own a cheap economy car with hard plastic interior trim, it’s not ever going to go back on quite the same as the factory...

The little loop thing that the latch hooks onto is adjustable. I had a rattle in my Murano for YEARS, and after taking the panels off the rear hatch, and riding in that area to identify the rattle location, I figure it out.

Adjust the loop!!!

I’ve adjusted it in and out. The hatch rattles while not latched.

I didn’t break anything taking mine apart. Much to my surprise

This says that if the aluminum is coil shaped a strong magnet can affect it.

That was my plan if I couldn’t figure out where it was coming from.

Tap the different panels and see if you get any buzz at all, of any noise, then try putting pressure on the seams and try again to see if it’s coming from between two panel joints, or just the panel resonance by itself. Or just add a bunch of sound deadening mat and see if it helps. Good luck, I know how frustrating chasing rattles can be. I took the whole back seat, sail panels and parcel shelf off of one of my Caddy’s and covered all surfaces and added foam between mating surfaces. It worked, but what a pain in the ass.
