Anyone else hearing a frequent air movement from the air adaptive suspension while driving under 45mph? The vehicle sounds like it's adjusting the suspension more frequently than I would expect.

Unless the air system behaves differently than my old one it shouldn’t do that regularly. Do you hear the compressor running a lot too?

sometimes, i hear what sounds like a balloon losing air in the back seat, and an occasional pssshhhhhhh when first starting to drive and mph is under 45. I'll have them check it when i go for an oil change. I've got almost 4k miles on it already because of the many NY<>PA round trips since I bought it. I won't be doing those any longer so I'll take it to service in the next 2 weeks.

Good idea. On my 07 the shocks air down occasionally but not so I can hear it, especially not while driving. You might also look on the GM or NTSB website for others with this issue.
