    2013 Leaf - Dead 12-Volt Battery every 2 Weeks

    Totally agree. Mine has saved me from being stuck. But I keep mine inside the car because I can't get my trunk open when the 12v battery is dead. I find it hard to believe that after four years and over 200 posts about this problem Nissan has failed to find a cause or a fix. To my own surprise...

    12v battery dies repeatedly

    Update on this situation: From January 5 until May 27, the Leaf ran as it always had--no dead 12v at any time. On May 27 in the afternoon, it's suddenly dead again. This time I had a battery pack that I used to jump it, but I would prefer not to do that too often. The only common denominator I...

    NissanConnect EV / Telematics Hardware Update, for the post-2G world

    A similar experience: After a couple of hours of work on this (and two interrupted Chat sessions with Nissan), I was told that my TCU Phone Number setting—that was showing four asterisks—should have about 13 numbers in it and that I will need to go back to the dealership and ask them to reset...

    12v battery dies repeatedly

    They were able to give me the draw, but they didn't find anything unusual. They ran diagnostics for two days and nights--on the charger and off. The car started for them every time. I'm at a loss at this point. I've ordered a portable battery jump starter and will try to continue diagnosing it...

    12v battery dies repeatedly

    The dealer ran diagnostics overnight and found nothing drawing on the battery, and the car started fine this morning. Could this be simply a problem of leaving the car plugged into the charger all night, even after the charge is complete? I tend to do that in winter so I can run the heat in the...

    12v battery dies repeatedly

    On Friday I had it jumped and then drove it there. Today we put it on a carrier and transported it there. I do leave it plugged in all night every night, but I've done that for three years without a problem. The dealership tells me the battery was still dead when the car arrived there so they're...

    12v battery dies repeatedly

    I will have to see if I can capture what might be draining it. I've had the car for three years and have not changed any routine that I know of. No new equipment in the garage or on the car; no. Ew Bluetooth devices in the house. This is a sudden and new development. The dealership is running...

    12v battery dies repeatedly

    CORRECTION: Wednesday work was not the 3G radio one (that's a week or so from now) it was the airbag recall part and software update.

    12v battery dies repeatedly

    I had the 3G radio upgrade done on Wednesday; the 12v problem began Friday morning. Is there a possible connection. The battery was (supposedly) fully charged when installed. No Bluetooth device active (I turn the Bluetooth off on my phone when I'm not in the car). It did run a charge cycle...

    12v battery dies repeatedly

    Four days ago I found my 2013 SL Leaf totally unresponsive. No lights (though the dome light came on once), nothing, and of course it wouldn't start. The dealer tested the 12v battery and found that it was not particularly low, but I replaced it anyway and the car worked fine for two days...
