Over the past several days, when I first press the "start" button in my car, I'm receiving the following message on the touch screen. "System Off due to battery conservation mode" There are also many alert chimes. No other messages appear, and nothing on the left screen. The vehicle is fully charged. I also receive this message when I press the "stop" button. It appears that I no longer have accessory mode. If I just press the "start" button, without foot on the break, I receive a battery conservation message on the left screen, not MFT screen. Additional Info: I just received an email from the car stating that my "12 volt battery is low". It appears there might be something amiss with the charging system and my 12-volt battery isn't getting charged at the end of the cycle, or my 12-volt battery is dying. It's a "new" 12-volt battery, as the dealer replaced it on the day I took delivery of the vehicle (October 2013). Anyone else experience this problem? Steve
