Hiss noise when parked
Hi all,
I tried to search but could not find this exact issue. I drive to the store and back home, when I get out I hear a hissing noise. I get in the car today and start it up to see if it hisses while running, the front left side rises a little so I turned it off and this time it did not hiss. Drove to the store and came back home no hiss this time either. Is this suppose to do this? Or do you think there is something wrong with the airmatic?

Does the car try to level while it is parked and locked? there is a recurring hiss/chirp from the front passenger side, continuously repeating. I am afraid it will run down the battery.
