2018 S Class exterior noise intrusion!
I’m experiencing significantly increased exterior sounds penetrating my 2018 S560 passenger compartment. I never heard tire whine from passing vehicles and the other driving sounds that I’d actually forgotten about. Dealer claims car is “within specifications “ subtly suggesting that I’m imagining it. I did back to back drives in both cars and there is very clearly more road noises penetrating the cabin in the 2018 over my really quiet 2015.
Anyone else hearing this increase in noise? Anyone had success resolving a problem with MB USA on an issue like this?
I’m contacting an acoustic engineer to quantify the situation.
What a disappointment on an otherwise wonderful sedan.

I was surprised they agreed. Made no difference. There is something different between the two vehicles. Dealer claims that the door seals are not adjustable...I keep pressing the window up buttons - that's what it sounds like...a window is not fully closed.




One suggestion would be to drive around and have a friend use a sound meter (just search for sound meter or decibel meter on amazon) to try to isolate where the noise is coming from, then you could point the dealer in that direction

Perhaps that will get MB’s QA attention.








I found occasionally that lowering the window a touch (like a eight of an inch or so) can actually create a better window seal. I was told that was due to the window motor stop was off and the glass was pressing too much onto the rubber seal, deforming it a bit.
Btw, all S550 wheels are cat aluminum, not forged...
Good luck!

i was told by the dealer that there is no door adjustment possible due to the robotic assembly system.
Does MB still have regional tech service engineers who get involved when issues like this can’t get resolved at the dealer level?

Thanks for the correction on the wheels, Wolf. So to confirm, there is adjustment possible of the door fitment; the seals could be replaced. This makes sense.

This is typical for issues with noises; most of the techs work on C or E class sedans/SUV's so to them a louder S-Class sounds just fine. No frame of reference. I once has a super charger issue on our SL55. Multiple techs drove it and said the car was fine because to them even a diminished engine was faster than anything else they had driven. Then an AMG tech saw it and recognized the issue in less than 2 minutes.
The wind noise is typically only on the front door/s. Try to drive another S-Class from their lot for at least 15-20 minutes for different road surfaces for reference. Then bring your car in and tell them to adjust the doors and swap seals, otherwise you are not interested to keep the car.
