2024 G 63
I paid $500 for a 1966 Volkswagen when I was 16 (my first car). It had a crack where the fender and floorboard meet, so a lot of water would rush in when I drove through puddles. The water puddled up in the back seat, so I drilled a hole in the floorboard 
I should have applied for a job at Mercedes. LOL

My 2020 G63 also has a creaking/squeaky noise - not from the air vents, but from the front driver's window and seal. I also tested the AC today in the garage and within 30 seconds of cranking up the A/C to 7, my ears kept popping. When I opened the driver's door, it almost flung open into my garage wall - it "popped" open a few inches more than usual when I open the driver's door. Incredibly uncomfortable feeling, even when the A/C is on in Park! Checked online and there is a service bulletin to solve it. See attached Mercedes service bulletin with the dealer's solution. Don't know if it has to do with my window creaking, so I may have them just fix that first.

My 2019 G63 had the whistling sound and they replaced it withe D pillar vents per teh bulletin and the sound is now gone. I also had a misaligned brush guard so that the right front parking sensor would go off at stop lights. They initially did a re-flash of the software and it got worse. Finally they saw that the right brush guard stuck out 5mm more than the left and re-adjusted it and now its fixed.

Pressure Issue
My 19 G550 has the pressure issue, it is terrible. I cannot be in the car without the window open or in recirc mode. If you open the door without these things on it shoots out at full speed. Your head hurts in it. Mercedes tells me its a problems others ha e but there is no solution now or for months to come.
Did anything come of this? I have a similar issue.

2019 Mercedes G63 Interior Cabin Pressure issue
Has anyone been able to have this addressed and actually fixed? I've been driving mine around for 3 years with the sunroof cracked. Live in Destin Florida so I have to keep a/c on high most of the year. Cabin pressure is so bad it hurts your ears and doors pop open. My local dealer can't seem to figure out a fix. Love the car but would really like to get this resolved. Any help would be greatly appreciated.
