Air escapes from the air bags. There are no punctures. Could it be a sensor?

    If air is escaping from the airbags then you have a leak somewhere. I had one that wouldn't leak unless the suspension was in a certain position allowing a small leak in the airbag to be exposed. It is possible that it is a sensor, but most likely that's not the case. I would double check all the lines and the airbags again for leaks.

    When I shut the car off I can hear air escaping from the bags. This does not occur every time. We don't drive the car every day. Sometimes the bags will stay inflated until the next time we use it and shut it off. That is why I suspect a sensor problem. I don't know where the sensor is or if it is a big deal to fix. Please advise.

    its your air bag that is bad just replace the bag for the side that keep deflating, my 2003 h2 hummer does the same thing, the bags are curved on the bottom so the air leaks sometimes because its rubber so it has slits, i would raise my suspension it takes awhile you might a have to drive regular as the light blinks but raising it makes the airbag extends thus going pass normal ride height and the bags stop leaking, but this is temporary so just replace it thanks

    i'm pretty sure it's the sensors....my 2003 h2 has had to been replaced 2 times already...both sides...went around a corner, lost some air from bags...parked it, morning all air was gone...it sits so low that the sensors can't pick it up...i jacked up just the body, then they kicked in

    For my suspension air bags (springs) I went to www.affordablestruts.com they were great. I hope I could help.
