Yes, just replaced ours 1-2 months ago.

Batteries are expensive. Nissan should be motivated to fix the problem to avoid more battery replacements.

They've got the solution to that, just tell people the replacements are back ordered indefinitely.
Has anyone had a 30kwh pack replaced recently? I'm wondering if they are out of production and they used up all the inventory they allocated for warranty replacements.

There is a rumour they have now run out of 30kWh packs and are working on a solution which involves 40kWh modules derated to 30kWh by updated BMS. Nissan will not want to continue with same chemistry if another replacement needed in two years. If anyone gets a new replacement it would be very interesting to see a screen shot of the main LeafSpy screen at full charge and the BMS part number (need LeafSpy Pro).

A derated 40KWH battery would suit me just fine particularly if they limit the battery to the middle 75% of its range. I still think that Nissan has picked the wrong chemistry and It is too sensitive to high temps. There doesn't seem to be a problem with these batteries in Europe or Japan so it may be localized to the southern U.S. It just may be cheaper to replace failed batteries then fix the problem. If I do get another Leaf, it will be a lease not a purchase. More likely, I'll buy or lease another brand instead. I've bought Nissans for almost 30 years but the response to the battery problem has left a bad taste in my mouth.

Nissan finished replacing our 30 kWh battery on 3/21/2018. On LeafSpy Pro that day the main screen:

AHr= 82.34
SOH= 103.60%
Hx= 97.45%
Odo= 18,729 mi
QC= 31
L1/L2= 660
SOC = 93.6%

Would post the screen shot here, but don't have the account upgrade to do it. Where does one find the BMS part number?

Thanks for the post. The battery controller part number should be visible if you have LeafSpy Pro, turn on Service Menu in settings (appears as 5th screen), then "Read ECU versions" and you will hopefully have a "HV BATTERY" line. On a 2016 24kWh ex Japan I see 4NL2A (part is actually 293A0-4NL2A) which is different to the 30kWh (starts 2015/12 with 4NN4A and updated to 4NN6A in Sept 2016 for Japan) and it will be interesting to see if any further updates. Another useful item on same line is the battery serial number - for the example I have it was JT11639000xxx which I understand means JT1 = assembled in Japan, 16 = 2016, 3 = March, 9 = day, plus serial. The manufacture date of your new pack would be interesting.

If iPlug's pack was replaced on 3/21 it had to have been ordered well before then. My imagination is running wild with possibilities here, but pretty much ruling out the possibility of getting 40kwh of capacity in a 2016. Even if it did it would likely degrade in the heat.

Thanks. Looks like assembled in Smyrna in August 2017 so older stock (now 9 months old). The cell volts at 100% charge is also of interest although as seems an original pack probably sitting about 4.12V.
If anyone else getting a replacement could check this it would be appreciated.

I am curious what your stats were when you dropped 4th bar.

It should be back in this thread, probably around the month of March.
