2008 GX470 - air suspension settles overnight or after a few hours

[bhendron]

This started happening over the winter. No other issues really, but the there is a few minutes when I first get in and start it that the suspension is bumpy until the bags reinflate.

Since they appear to be sagging at an even rate (both sides), I'm thinking its not leaking from the bags? What might be the mostly likely problem?


Thank you.

You have a leak for sure. May be a crack at the seam in a bag or at a junction.

Thank you.

I also have a 2008 GX470 with KDSS. After parking and exiting the vehicle, I regularly hear an audible hiss (as if the airbags are deflating) and can see the rear settle slightly. I assumed this is normal. Is it, or do I have a leak?

Both of mine have done that. I think it's normal.

Mine does the same thing. I assume it it normal.
