The dealer replaced my 12v battery and did the recall reprogram while I waited.

I had a dead accessory battery this evening, ad the T/M error as well. Charging the battery for 1/2 hour got rid of the error. Now I have to worry about the damned accessory battery's health. Ironically, I have it hardwired for a maintainer, but haven't used it a lot this Winter. I think the 12 volt throw blanket, plus the seat heater and wheel heater, all running together, caused the little battery to run a deficit. I told myself that the long L-1 charges, plus my 35 minute commute, should keep the battery charged. Well, probably in Summer...

Has anyone investigated how much battery is needed to "jump" these cars? I have several 12 volt UPS batteries that are used, and read 12.89 volts charged. They were originally 10AH. Would one of these suffice with a little lead with alligator clips, or do I need to keep carrying a larger battery, and cables?

I used a 10 year old, 7 ah ups battery, to jump start my LEAF.

Heh, that answers that question! I was a little concerned about resistance from the near-dead accessory battery, but I guess that isn't an issue. Thanks. I'll be using a UPS battery and a little alligator clip/wire/tab connector setup I cobbled up in 5 minutes last night. But I think I'll still carry jumper cables...

All new Leafs should come with a hardwired battery tender plug, and a complimentary battery maintainer. Maybe someday I'll be able to get mine to a dealer again when it gets into it's "rampant vampire drain" mode, which generally occurs monthly. I sure wish the dealer I took it to in Edmonds, WA wouldn't have blown their chance to diagnose the problem. May have shed some light on an (apparent) widespread problem. Meanwhile, my Leaf lives on a battery tender at all times when not being driven. It simply cannot be trusted to take care of itself.

You should be able to skip the tender while it's plugged in and actually charging.

I completely forgot to post any update after I took the car to the dealership. They tested the car ( or that what they said) and found nothing wrong with it; since many have mentioned that the 12V battery was the culprit, mine runs fine since March 2011 when I took delivery of the car.
I just hope this is not going to happen to anyone again in the middle of the road; I hope Nissan figures this issue out and provide a fix.

My concern is that 12 volt battery was damaged and will now do it again, when I don't have time for it. Lead-acid batteries don't like being run that low (although it looks like the car shuts the non-memory drains off at some point,leaving the battery just very low, not dead) and tend to get damaged by it. And I know if I take it to a local dealer they will find nothing wrong...

I got this message today. But noticed it after slipping on icy snowy road.

THIRD TOTAL SHUTDOWN

Posted: Sat Mar 29, 2014 9:01 am
by leafhopeful
Took delivery of a 2013 "S" model in October 2013. Yesterday, had my third T/M Malfunction resulting in total shutdown of vehicle. Third tow to dealer. First time, replaced entire motor assembly. Second time, Leaf Engineer flew in from Smyrna, TN to supervise inverter replacement. Have no idea what to expect now. Clearly a serious design flaw. Total shutdown is very disconcerting especially as first two happened on Interstate and yesterday's happened in the intersection of two, six-lane state roads. Police have had to shutdown traffic and manually push car to safety all three times.

Will get to see up close and personal Nissan's customer service. In Florida, this series of incidents triggers the "Lemon Law" provision. Hopefully Nissan will take the long view and do the right thing without forcing me to file paperwork with State of Florida.

Anyone here had anything similar to this on 2013 "S" model?
