2016-2017 model year 30 kWh bar losers and capacity losses

[SageBrush]

I think this is a scam

It is not.
However, the car will take a couple months to recalibrate the BMS before you will have a good idea of the battery health. If your battery really has degraded into the 70s SOH it will be apparent to LeafSpy (and by capacity bars) by spring.

Jan 1, 2021 update. 285 GID's, SOH=78.52%, Hx=52.10%. 84146 total miles, 39217 miles on new battery, 145 L3 total, 31 on new battery, 1668 l2 total, 794 on new battery. I'm still not driving a lot these days. No real change in the battery this month, It is cool and mostly dry here which is easy on the battery. It is still iffy that the battery will lose 4 bars before the warranty expires. Most likely is that it will lose the second bar shortly and most likely the third before the warranty expires but the fourth won't drop in time. At this point I'm waiting to see what Biden does with domestic EV credits. The ID4 doesn't look like it will work as well a Tesla 3 or Y for me but the $7500 tax incentive is tempting. If I could get something similar on a Tesla, that would tip the scales to the Tesla. No matter how cheaply I could buy a Leaf right now, I don't trust Nissan to stand behind the car nor have they addressed the battery problem. The Aryia will address that issue but it won't be available till late this year or the beginning of next year and I still don't trust Nissan.

There's also calendar life degradation. If your leaf is parked under the sun during the summer, it will still degrade without you adding any more miles, extending your remaining 15k miles of coverage.

It sits in a carport that's mostly shaded. Doesn't help a lot on 100 degree+ days in the summer. As it stands now, I'm down to about a 75 mi range and it's 10 mi to anywhere and 14 mi to the grocery or fast food. I am keeping the battery at full charge most of the time in case i need to run out for something. I'm expecting the battery will last till just past the warranty and hoping that it fails earlier rather than later. I suppose I could try to game the system and let it sit with the A/C running full blast to run the battery down but that's not a sure bet and a PITA to do. If I'm lucky, Biden will push for a EV credit extension of some kind and I'll take advantage of the tax break.

Is there a way to tell if the battery firmware update has been done? ECU version number from LeafSpy perhaps?

I just picked up a 2016 with 42000 miles and 5 bars down. LeafSpy is showing SOH=55.6%, Hx=53.41%. Only 3 QCs but nearly 1800L2s, I am guessing the previous owner left it plugged in at home permanently.

I am thinking I got a good one that will get a new battery easily but am trying to figure out if I will have to jump through the hoop of a firmware upgrade and wait for bars to drop before getting the new battery.

I just called Nissan's National Leaf hot line and was given a case file number before I ever contacted a dealership. They can tell you the history on your battery. I emailed a photo paperwork containing my proof of ownership showing my name and VIN. My Nissan case number stopped dealership blowback in my case. I live in a region with anti Leaf Nissan dealerships.

A range test or charge test would tell the tale about the actual battery capacity. Something to do while you wait to find out if the software update has been applied.

I'm not driving a lot these days, maybe half of what I used to. No real change in the battery this month, It is cool and mostly dry here which is easy on the battery. It is still iffy that the battery will lose 4 bars before the warranty expires. Most likely is that it will lose the second bar shortly and most likely the third before the warranty expires but the fourth won't drop in time. I could look around for a 60KWH battery but I think I would be better off putting that $10K towards a new car instead. If I do get a second replacement battery, that just delays the inevitable. The software and hardware is improving so rapidly that even a 5 year old car is functionally obsolete.
