I can say with our 13 S it is a bummer, we have had it happen three times in the last three month and it is totally random. These most recent onn was while out running errands, third stop at a store, came out and it was dead, once at work and once when we woke up it was dead and hadn't charged the traction battery becasue the 12v had died. I do at least once a week, usually twice, charge the 12 battery and even replaced it last summer again with the same larger 51R that has 1.5 times more capacity than the 35N. It is the randomness of it that totally drives me nuts.
You should measure the stand-by current draw on the battery, 3+ minutes after locking the vehicle. It should be about 50-60ma (.050 - .060 amps).
Your TCM ECU (telecommunications) may be randomly powering-on
