Not normal. You have an air leak.

I ain't got one and this reinforces the reason that I do not want one . I believe in the KISS system . Manual always works .
If you ain't got it then you do not have to pay some one to get it fixed !
This is not what you wanted to hear !

Do you have a single or double channel? With my double channel setup if something made the truck lean it would let air out of one side and put air in the other to keep the pressure constant. Anything that changes the weight on the rear end resulted in a pressure adjustment, quite often the opposite of what I really wanted. Putting a load on the back compresses the air bags, raising the pressure, and the system releases air to maintain the set pressure when I really need air added to get back to the desired height. I am not saying that this is the problem. It does sound like you have a leak but these are things to consider as well.

Not normal. I have the automatic system and it never has to come on to maintain pressure (talk about simple, I haven't touched it in years).
You have a leak someplace.

You should be able to see the leak by spraying Windex on it. I would then eject the connection and cut the line square and sharp with a fresh razor blade. Then reinstall.
