    2018/2019 Leaf SL - Bad battery cell - "Service EV System Unable to restart after power off"

    I had the same message this morning on my 2018 Leaf. Roadside assistance finagled with it a bit in an effort to get it in the flatbed. Then, couldn’t get it into Neutral anymore. He ended up pulling it while in park—apparently he trying to slip some plastic skids under the front wheels...

    2013 Leaf - Dead 12-Volt Battery every 2 Weeks

    Another status update (a/k/a "vent"): My 2013 3G-TCU-upgraded LEAF SL has failed to start under its own power each morning for the past week+, each time, needing to be jump started (because of the TCU-induced 12V battery drain). The third "executive" level person I was passed to asked me to...

    Of course, I was hoping for a solution other than "just disabling the 3G/TCU." By analogy, if the using the heater caused the drive motor to stop, driving only during the summer (or wearing really warm clothes) is not the workaround I'd hope for from Nissan.

    2013 Leaf - Dead 12-Volt Battery every 2 Weeks

    I have a 2013 LEAF with the 3G TCU upgrade and am also experiencing the frequent 12V battery drain. Has anyone heard of a successful resolution? E.g. replacing the TCU again and lucking onto a 3G unit that works? Or Nissan resolving the issue in some fashion (short of just disabling the...
