I've been driving my amg gt for 3 years and hearing rattling noise. It seems to be coming from cluster area as if things are loosened up. Is this normal experience? Is it fixable?

It’s definitely fixable.
You may also want to check the rear hatch and hood hinges. It can be hard to pinpoint the origin of sounds in the car - probably because the entire car is aluminum and the sounds travel in the small enclosure.

Thanks.

There are a few threads here about how to solve. First step is to isolate where it’s coming from.
On mine, it was the hood hinge on the passenger side. To check, with the hood closed, put your hand on the corner of the hood (where it meets the windshield). Push up and down and check if there is play. There was a bit of play on my passenger side hinge. I would have NEVER guessed the rattle was coming from there - it sounded like it was coming from the hatch area.
There’s a bunch of stuff you can do in the rear too, such as putting hockey tape on the latch (the metal bar that gets grabbed by the lock), and removing the plastic trim pieces.

Sorry for necroing this thread. I have the exact same issue with my 17 GTS since I got it in 2019 but I thought it was normal. I took it to the dealer late 2020 and they said the window regulator cover in the right door was loose/deformed. They replaced the cover, but it didn't solve the rattling. This is the first time I've read a thread describing the exact same rattle as I have: a rattle that sounds like it's coming from the center cluster as if something is loose. Did OP or anybody else figure out the cause of their rattles? I played with the hood hinges and there was no play that I could detect.

My rattle sounded like it was coming from the rear/hatch area. It turns out it was one of the hood hinges. There was a tiny bit (~1mm) of up/down play which was noticeable with the hood closed and latched, if you put your hand on one of the corners of the hood (at the base of the windshield) and “pulled” the corner up/down - there as a tiny bit of play. They replaced that hinge and since then the rattle is gone.

The rear area has a lot of potential for rattles, and I added felt and hockey tape under the plastic trim panels, where they contact either metal or other plastic panels.

But I didn’t have any central console rattles (yet). Sometimes in summer when the transmission/engine are cold, the panel just above the cup holder (where the adjustable traction control knob is on the GTR) rattles a bit, but it goes away when everything warms up.

I have also heard that the COMAND screen can rattle. Try putting some foam or a sponge between the screen and the dash and see if that helps. If it does, then you can think about how to fix it permanently.

I haven't looked into the rear yet but I'll give it a try. The issue with the rattle is that it sounds like it's coming from the center console, but it may very well not be a loose part in that area. I'm in CA so the temperature fluctuation isn't that bad year round. I get the same rattle no matter the season if I'm going over a rough patch of road at normal local speeds, but not always. It's pretty annoying to try to explain to a dealer SA.

edit: I just played with the panel above the cup holder under the center ac vents. The whole panel can tilt back if I apply pressure towards the back of the panel. Is that normal? I had always assumed that it was just as solid as the dash.

Agree that it’s annoying!
Try each main component of the center console to isolate and find the culprit.
1) COMAND screen: wedge a sponge or foam behind it and the dash
2) press down various trim components while you drive

Good luck and let us know what you find.

The panel you're pushing on is pretty normal movement. This panel just clips on with two wedge spring clips. Interestingly, there is a third, center clip that doesn't have a mating part to lock and it makes the center of this panel feel like it can be pushed in, then it gets more solid as you press towards either edge.

The panel comes out quite easily. Just use a plastic interior trim tool, pry one of the long edges first, then pop the other side. Here are two pics, one with the panel in place but popped out. The other with the panel upside down laying on the console. The two circled wedge clips are holding the panel in place in the circled slots. The third clip with the arrow does nothing. Looks like a design ooops....

I doubt this is your rattle, but if you do simply pop it out completely and take a drive. One pretty common rattle that sounds like it is somewhere in the cabin but the sound travels to different places is the interior door pull. It is very easy to isolate. As you're driving and hear the rattle, just put your finger behind the pull and lift very slightly. If the sound goes away...that's it. Could also be the pull on the passenger's side.

Interesting! Thanks.
When you say door pull, you mean the door handle, or the metal part that you pull to open the door from inside?

It's the metal part that you pull to unlatch the door from the inside. It is definitely the "rattle" I hear inside in my car when I'm driving. Simply put your finger behind the metal as if you're going to open the door, but just lift it slightly off its resting place. See if the noise goes away.

I see, thanks. Mine don’t rattle, but good info to have if they ever do!

I tested this on the driver side and nothing changed. I had a friend test this on the passenger side but I wasn't able to replicate the rattle consistently with limited time. He said he hears it from the door handle area and I didn't hear the noise when he was holding it. I also noticed that the handle mechanism feels a bit different on that side, but it's difficult to describe the difference (the driver side feels more tactile while pulling the handle). I'm going to have to test this further. Did you ever get this issue fixed or do you just live with it?

I'm living with it for now, but I only seem to hear it when the weather turns cold. Once it warms up in the summer, everything seems to "tighten up". Since this thread, and just yesterday I was driving surface streets, definitely heard the rattle, lifted the pressure off the driver's side handle and it stopped.

These are usually issues I eventually tackle myself, but another member who has/had the same issue took it in and they replaced the entire handle mechanism under warranty. He claimed it took care of the rattle. It was in a thread about 6/8 months ago.
