Air Suspension Question while towing

[brucemac]

2022 Suburban LTZ 6.2 38K Miles

Was towing home this past weekend with a travel trailer. Was pretty hot out, around 90* F.

We were little over halfway home on a 4.5 hour trip, flat ground, decent roads and the wife and I heard what sounded like a pop, similar to a tire blowing out, maybe not quite as loud, but you get the idea. We pulled over, got out and inspected everything. Everything seemed fine. It wasn't until we pulled back out on the road that I thought about the air suspension.

We got home just fine, no change in ride or towing characteristics. No messages on DIC/cluster. I've put some weight in the back, air compressor sounds normal, changing ride height doesn't bring up any messages and air bags seem to be filling and emptying fine. It does ask me to change to 4L on the highest setting, but I believe this is normal.

Is it possible the system let out a burst of air due to heat/temperature during the drive and this is what we heard?

Anything else I should be checking for? We're getting ready to head out on another trip next week. Thanks in advance for any insight or guidance.

If your suspension system is still working correctly, I very much doubt that the sound that you heard was related to the air component of the suspension.
