I am 98% sure it's the electrical plug to the 3rd brake light. That thing is not tightened down at all, and it's between the two metal panels of the inner and outer body of the hatch, so you can't get to it to tighten it down. That's where my foam idea is coming in.

Hmm looks like I have a decent amount of things to try, mine is the touring/sport so thurs I'm gonna get up early and start one by one trying to isolate my rattle. Where can I get the dynomat stuff or whatever it's called?

To anyone interested, a weird thing happened yesterday morning. As I was taking my car in to get my two rear tires changed, I did the head liner check on the way in. In my case, the headliner wasn't the culprit.

The weird part is that after I replaced my rear tires the buzz was nearly gone! The tires that were on there previously were stock RE050As, but whoever had the car before me sprung for the run-flats. My right rear tire was WAY low, like, 1/32 low. Since the buzz seemed to come from the rear right, I wonder if the harmonic resonance of the tire caused it at certain tire rpms, especially since the run-flats have such stiff sidewalls. My new tires are not run-flats, so softer sidewalls (and holy Moses, what a difference in ride comfort).

My drive home was in a bit of traffic, so I couldn't really give it a full test. I'll keep researching over the next couple days.

Any thoughts? Any similar experiences?

How big of tires did you go in the rear?

Also, I have the same issue as you and even with 275's on the base 18"s- I can still hear vibrations. It is reduced though, like you mentioned.

If you have the time, call GTM Mat and order their sample of material and do your trunk. That might help a ton..

If I decide to buy their midpipe, im definitely going to have to mat my trunk

I have the stock sport package size tires. (275/35/19) They're a different tire though than stock. They're Potenzas, but they're the S04 Pole Positions.

I drove around briefly yesterday on my way to work, and the buzz was still basically gone. It only happened when I really got on it once, which I can probably deal with since I don't do that a whole lot.

However, in another fun turn of events, I drove around BRIEFLY because when I got back in my car after stopping for lunch, STEERING LOCK. I knew I shouldn't have been putting that off like I have... So the Z's at Nissan. Thank god I bought an extended warranty. It's left me stranded twice in 6 months. (Last time was clutch cylinder crapping out.)

I did put some generic matting in the trunk about a year ago when I put in my subwoofer, but I did an admittedly crappy job. It was cold, and I was short on time and patience, so I kinda half-assed it. I should probably go back and do a better job.

Oh, and I see you have plastidip in your signature. What did you use it on? I'm planning to gloss-blackify my wheels because the coating on them is flaking off. (another aggravation) Did you get the results you were looking for?

How hard was it to remove the panels? I want to do this soon..

I went to get gas las friday because the car had about 40 miles til empty. I get back in the car after filling up and my brake wont go down. Push button didnt work. Car wouldnt do anything. STEERING LOCK. Had to have it towed to Nissan which cost $78 and then $100 deductible. I guess it was better then the $1300 they wrote on the invoice.

This might help. I made this video awhile ago before I vinvyl wrapped my roof and redid the headlights a lighter shade of dip

Well la-di-frickin' da for you! Ha. Just kidding. Seriously though, good for you, because it's so agitating. It's one of those things you may never solve if you've got it... Hopefully mine continues to be a relatively dead issue. Do you like 'em so far?

The trunk panels weren't that tough, just tedious, like any other interior stuff. There's a lot more junk in that trunk than I thought there would be. If I remember correctly, which I probably don't, I think there was really three big plastic pieces. One around the back of the hatch (near the latch), and the two sides coming up over the wheel wells. I also found part the previous owner's mic stand in there, buried under the spare. Bet the dude looked for that for quite a while... You just have to go through a bunch of pop rivets. Be careful when you take off the rubber liner around the hatch. Make a mark on it for when you replace it, so you know how to line it up. It's just a big rubber ring, but it kinda forms to the shape of the opening, and can be a B to reinstall if you can't set it up the way it was. Also the metal edge under it is a little sharp.

Now, you're in AZ, so your laws are probably different, but do you get any flack for covering your tail lights like that? I don't know if it'd be a problem here in PA. You can see the brake lights, but what about regular tail lights? Plenty visible?

Hey, Ron just another thing to check, but one of the clamps on my tail pipes was lose and it was causing a rattle. I change it out and that resolved most of my issues.
