Hummer H2 Problem Report

Hummer H2 Rear-end lowers after being parked

(9 reports)
After my H2 is parked awhile (mostly overnight), I will find the rear end has "dropped" approximately 6" as compared to the height of the front end. The rear end will regain its height once the engine is turned on. This happens intermittently. -
I get a "service air suspension" message, the compressor runs either constantly or not at all when the message is displayed. This doesn't happen all of the time, just randomly. Sometimes it completely drops the rear air suspension and sometimes it's just fine.... Drives me crazy! -
I was the second owner of my 2003 Hummer H2 and the air started leaking from the rear compressor or tank about one month after buying the vehicle, I have tolerated it until now ( about one year now ) because now I have to stop and restart it just to get 25 miles now! Any ideas what I should do next like a conversion to shocks and springs or repair/replace the expensive part ? -
