Hi, and welcome.
Not so fast about fixing things, that may not be broken.
While these cars should stay up and level even for weeks and months, it does not take much to lose pressure.
The front drops first since it uses more/higher pressure than the rear.
A system of lines and valves, leveling valves has numerous possibilities of leaking.
All connections have o-rings to seal them that go bad and so on...
Pumping "the car up" every time will lead to excessive compressor wear.
Sending you a PM for more info.
