Yeah I noticed this on my new MY14 about a month ago even after a couple 250/300km runs, message up start/stop unavailable.
Took it to shop but of course it wouldn't do then, it was fully charged and start/stop worked perfectly.
Then last week noticed it again plus it won't even play the radio with ignition off, get a battery low message up, so off to dealer again when I get a chance.
