This morning I went to drive my 2003 H2 and noticed that the right rear of the vehicle was almost sitting on my 37" tire. It also looks like the left side is a bit lower. I know I have air suspension but do not know what causes this problem.

I also know I have seen this issue on the form before but I did a search ("air suspension") and got very little back to help me with this issue - any direction or corrections for this problem before I head to the dealer. Thanks
