If you have seen lower back several times but the car raised by itself before, then you have to replace air spring. I replaced those with Arnott air spring. If you had this problem for the first time, your air spring will be fine. If you have 4 corners air spring and the front one blows air in and out, your pump is okay. Then I will first replace air suspension relay which costs $30. And you will have to check air hose connection. Finally you could try to replace air pump.
