I have a 2008 H2 and for the last year, i have had an issue with the shocks deflating. I have troubleshot to the point, i know it is not a leak. Something is just telling the shocks to release air.
Example. I get in the vehicle, turn the key and wait for it to fill. I also have the button to fill an additional 2 inches so i hit that. Drive to my destination. Come out after 8 hours and it is still fine. Drive home (not hitting the button to add 2 more inches of air) park, and the next morning it is deflated. Now if i would have hit the 2 inch button before leaving, it would have stayed filled all night.

Any Ideas because there is nobody to fix it locally and nothing on Youtube.

 

Very easy, the system is garbage, get rid of it, go with coil springs, problem gone...

 

Put up security cameras, it's probably Tom Brady.
