Disappearing Brake Fluid

2007 g5 2.2l, owned for 3 years, brake fluid seems to go from full to brake warning light activation of low fluid every ~12 months, checked everything, lines, wheel cylinders, new calipers, and no sign of external leaks anywhere, any1 else have this issue.
i think maybe master cylinder, but where would fluid be hiding, i did loosen it to see if fluid behind it but a quick check revealed nothing, pia to remove totally.
brakes seem to work fine although a little mushy by my standards but mechanic doesnt think so.
mechanic could also not find anything
