Maps has always seemed to run on ICS once installed..
Not sure why... Even if you kill the app it returns ...
It auto-starts every time I boot my phone. I can see it in the recent apps drawer. I swipe it closed and it doesn't return so hopefully it's not running somewhere in the darkest recesses of Android OS killing my battery...
Its the newest update I believe if you go into settings/apps and to maps click on uninstall updates it should stop worked for me.

I have always heard that you need to open it and let it lock in your location and then it will stop running. Seems to work for me ....
