my 2006 sut air ride deflates every 4 to 5 days.i use the inflater button it lifts to the max and stays there.look cool but im 65

 

Find the leak! Spray soap/water solution, same when checking tires for air loss. I also use to check natural gas pipe line fittings.

 

It will not stay at the max height either. As soon as you hit 40mph it drops back to the standard ride height. But yeah, quite obviously there is a leak somewhere. Could jest be the bags are worn out and need replacing.
