I realize there are quite a few threads on this topic. I couldn't find a definitive answer on this so hopefully someone knows what's going on.
Recently, I've noticed that only the passenger side rear suspension gets pretty low when parked. This does not seem to happen on the driver's side and you can see a clear leaning condition when viewing the vehicle from the rear. This deflation does not happen immediately, but more like the next morning or two mornings later after the vehicle has not been used. When we do use the GX, the ride height feels normal and the suspension adjusts heights normally. I can hear the motor inflating without issue and see the height rise gradually.
Does anyone know if this is just wear on the bag itself? Or some combination of things? This is a 2005 GX470 that does not go offroad ever: regular city driving only. Hardly ever tows anything.

Likely a leaking air bag, consider it a warning sign and get it fixed before it won't hold air at all.

99 times out of 100, odd behavior with the rear air suspension is due to leaking airbags. The airbags just get old and cracks form in the rubber causing the leaks. It seems this is more related to age than the type of use.
Quality aftermarket sets can be found on ebay or Rockauto. If you have a shop swap them out for you, make sure they're familiar with toyota/lexus air suspensions (I went to one not familiar and they broke an air line fitting). Or there's many options to switch to a conventional coil spring setup.
