H2 with only 1,300 miles and now the Air suspension is again having problems... First time, it was a connector on the compresser... Now it looks like the bladder on the driver-side has a leak... each morning the truck is tilted 4-6" down on the left side... Kind'a funny looking from the back side...

Just want to know if others have experienced the same problems... and how the dealership dealt with it... is this a common problem on the H2 Air suspension...

I have heard story's about people loosing their airbags off-roading and, the mechanic told me that springs are better for the wild.

Front Locker, Stealth winch, 37" Super Swampers SSR,low center of gravity = Ultimate H2

My business neighbor experienced the same thing. His is 10 months old has less then 500 miles on it and the only off roading would be the gravel lot to the back storage buliding.

Did a search and could not find what I was looking for, but this has come up before. You are not experiencing an isolated incident, unfortunately.

Hmmm very interesting. I am taking my 04' in tomrw for this exact reason. The tech's advising that they havent herd of this problem before! Im having a problem believing that one!
Ill let you know how things work out. by the way, mine does not have the optional air susp. adjusment.

Well, the story just gets better... The truck went into the shop for 4 days... the rep stated they worked 9 hours on it and came to the conclusion that it was as simple as recalibrating the air suspension, as it looks like the previous dealership did not recalibrate after installing a new compressor...

Fine, I'm go with that... I get the truck back after 4 days... only to have to start leaning again the day after I get it back...

Same side, etc... but now the air pump just keeps on recycling and doesn't stop...

I call up Hummer CS, and explain that I now have to take it into the shop for the third time, and explain I will pull the lemon law if it is not fixed this time...

I hit the dealership this morning... drop off the truck... just got word from them... it's fixed, it was a module now.. Gotta love the hit and miss mechanics...

I'll pick up the truck tomorrow... and let's see if it's fixed...

Now the dealership is saying it's a torsion bar adjustment. I'm leaning roughly 1.5" in the left rear... Will the adjustment actual take this out.

GM quick fix #95:
Try letting the air out of the passenger side rear tire until the vehicle is level

Yes we have also problems. The Display shows "Service Air Suspension" and after that the h2 drops down on the rear axle, the air compressor gets no voltage and we think it is aproblem to the air control module because all the valves except.the one controls the airstream also not powered by an voltage.

Overseas Germany Alex,

Good news... They replace the ACM on mine and the SAS error went away. Yet, it was still leaning to one side.. Then the next trip to the dealership and the adjusted the torsion bar... and that did it.. The truck hasn't had a problem since.

visualghummer,
wish you a nice time with your truck. I have ordered also the ACM but need a little time to come overseas. Mine is still in the workshop. Thanks for the information about the torsion baradjustment i will throw a look also about that.

Alex,

Please advise me on the outcome after the new ACM is installed.

One thing I noticed, it seems that the compressor runs a lot... I can hear it a stop lights, etc.... Not like the Ford Expedition that I had that had Air Susp. in it... That Compressor pumped it up and it stayed that way for days... I wouldn't hear the compressor...

It's not that way in the Hummer, I hear that compressor working all the time... Same on yours?

regards,
Jim

One of the most complained about problems at my local dealer is a "noise coming from the back of the truck". I kid you not. These folks either forgot they had or did not know about the air suspension.

As I understand, the air will kick on anytime the truck feels it is not level and release when it is. Thus you hear it often.

The quick fix, and I need to mention this on another thread, is to get a louder exhaust .
