Wind Noise Driver side window
My 2020 GLC 300 SUV has wind noise from driver side window along with bothersome interior pressurization when Highway driving 65-75 mph. Wondering if others have this issue and any fix for it.

Lots written about this back in 2016/7. Fix was two fold, acoustic glass to front doors, check your glass labelling or build data print out, second fix partly escapes my failing memory, I think they added something to rubber seal next to outside mirror set up.
Good luck, but go and hunt down the original posts back in 2016.
Check your frame seals are seated properly around internal door frame and seals on your door frame as well. No penguins were harmed in this explanation !!
Hope this helps.

Took my car to dealer last week for test drive and service rep confirmed the noticeable wind noise on highway but could not replicate the pressure issue. Rep called today and told me my car is eligible for acoustic windows which are now on order. Said he had similar problem once before on a 2019 GLC. I will follow up to see if the new windows resolve the excessive noise issue.

Well done.
Dealers here have not done this, they do quote around AU$1000 a side to fit and replace from memory.
So congratulations.

My 2016 had wind noise.
I tolerated it and did nothing about it.
When I ordered my new 2020 I paid a couple of hundred euro extra for acoustic glass in front doors...big improvement but I can't say for certain that it's the acoustic glass or other design changes that have made the improvement.
Crazy that on a €75k ($90k) Mercedes the customer has to pay extra to reduce wind noise!!!

Congrats on getting this on order. I couldn't get it from our dealer.
I have 2018 GLC which came with windshield acoustic glass and not acoustic side windows.
After reading some posts here on how acoustic side windows drastically reducing wind noise I've decided to replace them, bought from dealer total cost was about 400 USD.
Glass is thicker almost twice vs original. i didn't notice huge difference.
Seals could be a problem where the noise is coming from.
