Anyone figure out the cargo area rattle?

Mine sounds like it has a loose wire harness connector banging around when I hit a sharp bump. Dealer has not yet diagnosed...

Which side do you have it?

My noise is more of a creaking and to the left.

I've discussed my current progress in resolving this in my thread here: https://mbworld.org/forums/amg-gt-gt...hatchback.html

Mine is also from the left, more of a rapid ticking kind of noise. I'm pretty sure I've done a partial fix so far by wrapping every bit of wire and taping around the leading edge of the plastic hatch liner where it contacts the body but I still get a noise from time to time.

I also have a lovely buzzing noise from inside the centre dash area when I drive over coarse road surfaces.

Ooh, I missed taping the leading edges. Does seem awful creaky when you pull it around.

Away for a few weeks, so job for when I'm back.

It did indeed feel very creaky and as I mentioned the paint had been knocked through in a few places where the plastic nodules made contact. Mine now feels pretty solid... but still the final noise remains!

Something I've noticed that bothers me is that the panel gap between the hatch and the bumper is quite wide. The adjuster/strike plate behind the hatch liner was already at full retraction, I'm not sure if the lock part itself can be adjusted (maybe someone knows?) I've noticed pics of cars show a similar gap but others seem to be quite tight. Makes me wonder if this might have something to do with it all? Maybe the hatch doesn't compress the rubber seal enough?

True, the hatch just thunks down, but always seems to catch pretty easy, so maybe it isn't pulling tight enough.

Gaps look good on my car though.

I've checked the lock and unless I'm going blind it can't be adjusted. The adjustment is in the strike plate which is maxed. It could be slotted I suppose but my gaps are similar to yours Xbox, maybe slightly worse so it is probably the wrong tree.

Mine was the carbon fiber cross bar thing, it was always rattling and squeaking.

Rear Hatch Rattle Was Diagnosed and Fixed

A few months ago I had a rear hatch rattle on my 2016 Edition 1 AMG GT S. It didn't upset me because I knew this was an early production of a brand new design. I'd hear the rattle when closing the hatch (I wish they had a pneumatic valve strut that cushioned the dropping speed/force) and when driving over a serious bump. The dealer's service dept was able to fix the problem and the rattle never recurred. Unfortunately, I don't know exactly what was done to fix it (it's a large dealership).

The dealer also fixed a creaking sound under the car in the area of the engine placement. This too was successfully diagnosed and repaired. The issue was with a crossmember and I had the sense that M-B/AMG was aware of the problem. It was not related to a small recall related to the torque tube, I believe.

I've updated the other thread but to recap on the steps I took to clear my rattles from the rear hatch area:

Adjusted bump stops on hatch (solved the original loud rattling)
Lined the plastic hatch parts where they touch metal/paint with Tessa felt tape.
Wrapped exposed cables in the hatch itself and the fuse box area with fabric wire wrapping tape.
Wrapped and re-seated a pipe which sits inside the metalwork of the hatch. I'm not sure what purpose this serves.
Pressed a few plastic cable trays into their proper positions
Replaced the bump stop paint protection film with 3M helicopter tape
Added Velcro HD felt side pads on top of helicopter tape
Replaced left bump stop with new. (A190 750 00 00)

Very helpful post and thread!
My GTC has one or two very minor rattles coming from the rear hatch area. They are minor, and only noticeable on certain bumps. My AMG service tech is looking at the hatch adjustment now. Hopefully the fix is in one or more of the items you mentioned above.
Is it too much to expect that a $200K car is rattle free? It’s totally awesome otherwise!

It’s a sports car, it should squeak, rattle, groan, and smell every once in a while!

I added an adhesive felt pad (like Felt Tac) where the lift gate spring loaded stops hit the PPF. That took care of the rattles for me. It’s now a bit harder to close the trunk but it’s worth it.

I noticed each spring can be adjusted. Does anyone know what the adjustment does exactly?

Can you clarify: “Wrapped and re-seated a pipe which sits inside the metalwork of the hatch. I'm not sure what purpose this serves.”

I don’t see a metal pipe anywhere. Did you remove the plastic trim of the hatch? Or are you referring to the metal tow bar?

Wrapped hockey tape around hatch striker (U-shaped metal bar that the latch grabs when the hatch is closed) - made a big difference!

I had this and it was actually the hood! Check the hinges on both sides of the hood. Sounds counter-intuitive because the sound is coming from the rear; but sounds travel in this car unlike any other I’ve seen.
With the hood closest push up and down on the corners, at the base of the windshield. Check for play. I had play on one side. Chirping rattle went away when dealer replaced hinge.
