2019 G550 - interior cabin pressure too high...
Anyone else experiencing excessive cabin pressure with the a/c on and the recirculate function off? Seems like the pressure venting is inoperative and it hurts your ears?

Not sure if this is related or just normal. But I have noticed when I have used the air conditioning and then park and turn the car off, when I open the door it seems to pop open rather easily. Almost like built up pressure being released. Thought it was normal until I read this post.

The cabin/doors are water tight now - notice the new seals - yes, at highway speeds with aircon running fan-higher you can build "higher than last fen" air pressure - "original" carrie over upper relief vents upper rear quarter don't hack it as good as they should..

Unsure if it’s related, but I noticed when our 2019 G63 was running with doors closed (parked in our driveway) that there was air being blown out of two vertical black vents/slats at the top, rear corners of the truck (essentially at the end of the rear side glass). Perhaps this is part of an exhaust system to balance an overpressure to help keep it completely sealed?

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.

Of course the air rushes in when you open the door, pushing the door open (especially when done quickly) creates a negative pressure gradient as the door is opening until enough air rushes in to equalize it just like closing the door quickly creates a positive pressure gradient until the air escapes from the vents. The bottom line is you can measure this with a barometer and seek appropriate help based on the result. I have 5000 miles on my 2019 G63 ED1 and no pressure issues whatsoever although the door seals are tight so when they are slammed shut or opened quickly I can feel the pressure gradient momentarily.

Dealer told me that Mercedes has many people with the issue and several that have called service at that dealership over it. I don't think its teeny tiny. Service manager at my dealership told me he wouldn't accept it in his car but mercedes solution was to drive with the window open until they come up with a fix in 4-6 months.

Our 2019 G63 does NOT do that, not even close. That’s not a system wide issue — there’s definitely something wrong with yours. Hope they can get it corrected.
We can tell it’s air tight and ears sometimes pop at first if you open a window, but it’s not like that.
