Tanks are aluminum. It’s warranty, so taking it to dealer. Hope the tech is motivated…
lol, ya good luck. "maybe" they have a method to externally pump it up to higher pressure to help detect a leak.
I would expect to be put at the end of the line on this one....especially being warranty

It did leak down afte 3 days this weekend, so I may ask them to just keep it a few days and watch it. They are providing a loaner, so we will see. I documented the issue w/ photos as well...dealers around here are pretty decent, will see.

that should make is easier to find, they could come back with "that's normal" or some crap, even though we all know it's not. good luck

You might also look to see if GM put out any TSB’s on this issue.
Pretty up to speed on most of the TSB's, there was one early in production for very cold climates...but my vehicle was built after the engineering change to resolve it. And, it is not a cold weather thing...has been plenty warm here...at least until today.

Not a good sign for a 2 year old vehicle. This makes me very wary of the air suspension (on any non-commercial application). We went to test drive a few 2024 Suburban gas variants (5.3L and 6.2L). I noticed the 2024 Suburban Z71 with Air Ride suspension's rear was lower than the front by about 2" when it was parked before the test drive. It did return to normal height at some point during the test drive.

I bought the air due to my frequent towing…and for that it’s great.
