I don't believe this is truly "maintenance" per say. When you see this MFT has gotten itself into a state where it can't function and reboots. You're more than likely looking at a boot screen than anything really having to do with maintenance. Mine has done this at least 5 times.I know a lot of us have seen the "performing scheduled system maintenance" on our MFT's, but I'm wondering if this is actually supposed to happen from time to time. I've had it happen 3 or 4 times since I bought the car 7 weeks ago.
