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?

2019 G63-when it’s here
No worries, as soon as the windshield cracks, that will relieve the excessive pressure buildup!

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 itís 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?

Correct - those "rear gills" are the pressure/release vents.. carry over from last gen
