Ivan2408 wrote:Purchased used 2013 Leaf S in Dec 2015. It has been 100% trouble free until just recently with no prior warning my car wouldn't start. Every single light on dashboard was illuminated. Would not engage on any gear as other posts have described. It wasn't until a few days later when I check on it again that it displayed "T/M System Malfuction". I was dreading having to pay to get it towed all the way to dealer (about 40 miles).

After Googling, I found these posts here. Sure enough I pooped the hood and the battery's terminals were REALLY corroded. So I replaced the battery with new one and after installing it I'm back in business with no problems at all. Saved a ton of money by looking in this forum vs towing and paying diagnostics, parts and labor at dealer. Thanks!!!

My 13 didn't have any grease on the terminals but my 16 has some blue grease on them.
Nissan probably started doing this after the above problems had been reported.

Battery terminals can be covered with sticky spray grease so they corrode less.
This is what is done on many cars that have battery exposed to the elements.

In a pinch you can use white petroleum jelly. Just keep in mind it will rot rubber/plastic terminal covers.

I had the T/M error message this past week (Nov 2017). Had left the car for a bit over a week between drives as I was away on vacation. It's a 2013 so the starter battery was near the end of its life span (4-5 years). I used a plug-in battery charger to charge the starter battery for a few hours, and the problem cleared up enough to start it. Drove it immediately to an AutoZone and they replaced the battery for me and the problem is all cleared up.

There is no "calendar lifespan" for lead acid batteries.
Many last for more than a decade. In cars, in UPS devices, submarines, forklifts.
It all depends on conditions.

I have a 2014 LEAF purchased August 2016. This last winter the battery died, so I replaced it myself. 3 weeks ago the replacement battery died, so I got the dealership to replace it. I learnt whilst it was in their hands that the error codes need to be deleted so I insisted they did so before I accepted the vehicle back.

Guess what?

This morning I switched on the car and the T/M malfunction warning came up. I could hear the Lithium Ion switchgear kicking in and out and have tried restarting. The displays flash and show tons of warning errors and I can't engage a drive gear.

Surely this can't be just another dead 12 V battery?

I keep a 12V lithium "starter" battery in my 2012 Leaf trunk for the eventual day that the original battery dies. Most recently, I was quite worried that after a 6 day trip (leaving the Leaf on a L2 charger the whole time) that I would need to use it, but it "started" fine. I do have LeafSpy Pro and leave the dongle in place, however it is LE Bluetooth -so seems to be no problem. I'm not sure if it was wifi or (none LE) bluetooth, that the battery might have drained. It seems (at least on my 2012) that the 12 volt system is not designed to handle any long term, significant drain. I do periodically slow charge the battery for a couple of days.

Bottom line to me is that the original battery was quite high quality, but the charging system is a bummer!

Update: The dealership have replaced the "Electronic steering lock" and I'm £850 lighter in the wallet. Anyone had a similar outcome?
