Really most air suspensions are trouble free for the first 4yrs or so.
Yes, it was only on there rear, but it was more than just auto leveling. The Denali my brother had had the auto leveling.
The Hummer when ordered with the air suspension had the full air bags in the rear instead of coils. It had a built-In compressor in the rear for inflating stuff and I could manually control my ride height via a push button giving it an extra 2" while negotiating a rock or something.
It worked great for the first 5 years, but then I had sensors go, the compressor went, and finally an airbag. Every time I fixed it, something else went in 6 months. Finally I took it to a spring shop and had coils put in where the air bags were. Then it was solid till I sold it when I ordered my Jeep.
