Creaking from chassis flex...
I'm relatively new to the boards and only recently purchased my 2013 550 and introduced myself on here.
So far been loving the GL but I need to take it in for the following:-
- Front headlights are fogging up from the top (where the DRLs are) - I believe they need to be replaced under warrantee.. Hope im just unlucky and that it won't happen again.
- Driver seat lumbar and massage function completely inop.. Could be a loose connection or something - nothing to get riled up about since these things happen.
- THIS IS WHATS BOTHERING AND ID LIKE TO ASK ABOUT... Has anyone taking the apparent common creaking issue up with dealership, it's a clear body flex issue which seems to be coming from the doors.. It's getting on my nerves and id really like a solution.. I know for fact many are facing this problem but I've done a search with no info.. I believe some commented about having weather strips replaced with no improvement?
Your thoughts please because I really wanna get this eliminated or minimized at the least.. If dealer is no help I may start getting creative with black padded tape on the inner door edges.. I just don't want to interfere with soft close system or induce air leaks...
Help please
On my introduction thread, two members told me it was normal and they both felt/heard the creak which seems to be coming from the door edges.. It seems to indeed be a valid structural rigidity issue typical of a heavy unibody structure. I just feel that there must be a way of solving the issue or minimizing the creaks at the least.
I also recall reading somewhere on the thread that another member had it looked at and I believe the offer changed the weather strips which didn't solve the issue.

Seems the lube, alignment, gasket replacement option is an involving process. Sounds like a recipe for accelerating rattles down the road.. In thinking of just experimenting on my own with felt tape on the door surround over the window.. I'm just worried it will effect the soft close system or develop air leaks...
It won't kill me if I just live with them but id be a lot happier if they're taken care of that's all..
I'll take it up with Mercedes on Saturday to see what they'd propose and report back with the outcome.. If they suggest sending it to the collision center, I may just overlook the fix and live with it

i should add that i can only hear this if i have the radio down or off. when i drive alone usually the music is at a medium volume and i can't hear anything from the car itself.
i agree it's annoying and shouldn't be present in a 90k car, but i guess i don't really notice it that often and it is also several times less noticeable than it was in my X164 so i think it's an "improvement"
but you're right - they should really lube and/or seal it up better for the $$$ it costs.p.s. sometimes i hear some popping noises from the seat back and i think that has to do with the massage bags/rollers. this is far less frequent but there is something "in there" that didn't exist when i had normal seats in the X164, so some noise is to be expected.
keep in mind these observations are when i'm really listening for them. when you have two talking/laughing/screaming kids in the back, everything else usually just gets drowned out
the creaking- yea i started the thread- my creaking seems to have stopped all by itself- not sure what it was- i could just be thats its soo cold- from the contraction maybe its just gone- lets see what happens once it warms up-- at this point, if it warms up any time soon.
I actually just got my first service done and told them about the rattles. I was fortunate enough to replicate every squeak, creak and rattle i've been getting in a short test drive with the service advisor.
3 main things (i'd recommend you guys to check out):-
- Door Creak (related to chassis flex)
- Passenger Headrest rattling against the rear DVD monitor (for those of you who have the option).
- Center Console!!! This is by far the worst, it seems to be made from cheap plastics, it squeaks, rattles, and squeaks all at once even when you're driving on the highway!!
- Wiring loom behind the Audio controls.
All four issues have been confirmed by the service tech. As 'fabbrisd1' suggested, the service tech advised the vehicle to be sent to the body shop for door alignment. The rest of the issues were looked at in the service dept.
Got the GL back, it feels more solid, the centre console is at least a 70% improvement and the doors don't creak as much. The rattle in the dash went away for the first day and then came back again. Passenger headrest rattle has completely been eliminated.
I'm still not quite satisfied. I drove a friend's 2013 Toyota LandCruiser yesterday and realised i almost forgot how solid those trucks are compared to the GL. Not acceptable IMO.
I really love the GL and am enjoying quite a bit but have seriously started considering trading it in on a Porsche Cayenne Turbo, or a Land Cruiser before it drastically drops in resale. I'm genuinely bothered by the rattles!

I also have a current model Porsche 911 -- its cabin rattles, vibrates, creaks and vibrates like a 200,000 mile Chevy. Just atrocious. I've had the Cayenne and it was a solidly built car, just like the Benz, but the materials quality was lacking. The Cayenne is more the size of the ML and a more enjoyable car to drive energetically than the ML, but never with the distance covering comfort and composure of the GL.

My 911 doesn't rattle at all, but the GL definitely is quieter!
Our GL does creak when the vehicle is substantially flexed but doesn't bother us too much.
YMMV:- I am surprised you say your 911 rattles, Porsches are generally very solid and utilise high quality materials in their builds.
My only problem with the Cayenne is that i'm not too fond of it's styling.
This is my other half
i find that more noticeable and annoying than the door/chassis flex creak.
i am due for my annual service in a few weeks and will be bringing these up to them, but i agree w/ blittle that i would like to avoid any real "body work". new door seals or lubricant or whatever would be fine, but i would prefer to keep it out of the body shop.
My 991 Turbo Cab is also quite creaky. MUCH more than my 991 4S Cab. I'm noticing a lot more cowl shake than 4S too.

I really wanted the 63, but NE winters require a more flexible 4matic. Also, the 550 has the insulated glass-same as 63.
Our 14' E350 cab is a dream. No noises and a wonderful ride. No issues at all.
Our 13' GL has way too much body flex to be "quiet". There are creaks with the door seals etc.. Its tough to have a quiet large vehicle. Think of how small the interior of a regular sedan is with a separate trunk. As for the GL, I thought torsional stiffness is always - always improved on a redesign? The X164 GL we had felt torsionally stiffer if only by a bit. Perhaps the Pano roof in the newer GL doesn't help...? Also the windows are double pane on the 450.
