The usual reason this happens t me is because of clicking the door handle just a tiny bit before hitting the power button. I never had it cause a dead battery, though.
Interesting. I sometimes open the door and then power down. Perhaps that's not such a good idea? Although that's exactly what I did last night (was listening to the tail end of a piece of music) and I didn't see this issue occur.

It was one of the updates that added a very annoying chime if you opened the door when the car was still on.

Happened to me after one week. My hypothesis is that CARWINGS communication is draining the 12V battery because it happened at the night after I enabled CARWINGS, and where I leave the car cellular reception is terrible for all providers and usually drains mobile phones batteries within hours even without using them. I've disabled CARWINGS and will monitor.

Carwings basically uses SMS functionality and the lack of coverage will not appreciably affect its power draw. It only transmits when it has something to say, unlike regular cell service. Thus, I seriously doubt Carwings is your problem.

I will try and explain better; just registering with cellular towers here is draining cellular phones batteries, even without sending or receiving anything. I was trying to solve the same problem for my phone only to realize that weak signal from several towers is causing the phone to "jump" from tower to tower and draining batteries while *attempting* to register. As for the leaf, so far so good, there is no drain on the battery. I will monitor for few days and then re-enable CARWINGS to recreate the problem.

I have the same issue, although the L2 says it's charged to 100%, the 12v is dead. I bought my car late March and it's been in the shop for 1 month now. The dealer couldn't figured out the problem so they called the engineering department in Smyrna, TN. They said they will change the OBC, supposed to arrive last Thu, well, now they say it is back ordered and there is no ETA, they gave me a 2010 Sentra in the meantime, but I can't wait forever.
I am an engineer, I know what the problem is and why the battery will die again. There are three simple solutions to this problem:
1) Replace all the lights including headlights to LED.
2) Add the solar panel.
3) Use a deep cycle battery, it will be better if they replace it with 2 6V 4D batteries. This will be the cheapest solution.

You may be an engineer, but none of those are "solutions" to the problem. The first two would have negligible effect. The third might well mask the problem, but it wouldn't solve it.

I hope that, like EVNOW, he just has a bizarre sense of humor... :roll:

Those are not solutions at all.
If my "new" 2013 car were in the shop for a month, I think I'd be demanding a new car!
(and at least a "Z" car loaner, not some 2 year old POS Sentra.

I've had my car for over year.
I've abused the 12VDC system, left the lights on, left the door open all night, hooked up an 8 amp inverter and run it for 12 hours, and left town for 3 weeks on a whim just to name a few.
What I have NEVER done, is discover a dead leaf.. Ever.

You need a New "new" car dude.
Lemon law them.

Carwings will use more power along with the car itself if its plugged in, has timers enabled, etc. Also, a poor cellular signal will kill a battery faster than any other draw. Any device with cellular access must poll the network on a regular basis. it cannot just lie dormant.

despite my battery hovering in the 12.2-12.4 volt range, i have never had battery issues but have never set a timer of any kind on the car. i think that has been my savior
