I have had the self leveling suspension leveling the car when the family gets out and the car is off. Mine does not sound like an air leak but sounds like the compressor is kicking on.

What is really fun is changing my winter and summer sets. The self leveling suspension starts going nuts when I jack the car up. By the time I am done, the car looks like it is on stilts.
