It is common for the system to do its thing each time you start the engine, but they do cause a real lot of headaches for people. The system will run also to raise the back end in response to how ever many dead bodies you have in there. When it starts to run repeatedly, one of the air springs or plastic hose going to it has a leak. Those can be fixed but it can take a while to find some leaks.
When the pump fails, and it will, you'll be in for a shock at the cost of repair, assuming the parts are still available. Most people elect to remove the system and install regular coil springs.
