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

Mon Mar 12, 2018 10:57 pm

Update to http://www.mynissanleaf.com/viewtopic.p ... 01#p519601

Seems like not many updates have been happening to http://www.electricvehiclewiki.com/Real ... 3.75.25.29 for 2016 Leafs.

Here are links to the 30 kWh 4 bar losers I'm aware of, so far. Please chime if I'm missing any 30 kWh 4+ bar losers, made mistakes, double-counted someone, etc. I've included their initials or MNL user name to help avoid confusion or duplication. I may go back and eventually add approximate mileages when the loss was reported but will round to the nearest 100 miles or so. But, IMHO, it doesn't seem that relevant except in cases of extremely high mileage.

Seems like these '16 30 kWh packs are dropping like flies in warmer and hot climates. Still wonder if there are bad batch(es), a bad range in terms of production date(s) or if it's inherent to these packs or model year '16 packs.

Let me know if deleting out the newlines/blank lines between each entry makes this list look too crowded.

It would make sense to also solicit reports from those who have lost zero bars and have more than 90% or so SOH, in an effort to determine what if any climatic and other conditions these batteries find tolerable.

Perhaps, but they all start out with all bars and over 90% SOH.

Questions: What age or mileage threshold should we be asking about? Should we wait until they're say 1.5 or 2 years old, starting from build month? Or, should it be that they've passed thru 1.5 to 2 summers since built?

DaveinOlyWA had excellent stats on his 2016 S 30 before it was wrecked, but he was in the mild PNW AND it was an S 30, making it relatively new vs. all most 2016 SV and SL. I first heard about the "S 30" from https://www.greencarreports.com/news/11 ... gher-price which is dated Oct 11, 2016.

From http://daveinolywa.blogspot.com/2018/01 ... e-all.html, he said

I think that because of the calendar issue, it would make sense to start with Just 2016 30kwh Leafs, and ask for LeafSpy and other stats, like location, build date, and charging habits, from cars with 95% (93% ?) or better SOH. Later on it would make more sense to ask for 2017 cars with 95% or better SOH as well. We want to figure out if there are whole regions of the US and Canada where they don't degrade fast, or if it's more a case of an occasional car "getting lucky" by not getting hot enough for long enough to degrade fast. That kind of info might also support or finally refute entirely the "bad batch" hypothesis.

We'd have to rely on people posting here. There will be a natural bias towards bar losers, because people with zero issues don't seek out this site as often as those with problems. Auction info was critical in discovering the Canary pack problem with the 2013 Leaf; maybe it could help with this as well, when more 2016 cars get auctioned.

The difference is that the 2016 cars have a much better degradation warranty, so even if they are degrading faster, fewer are likely to get auctioned, at least not prior to battery replacement.

I think the people leasing the car will, after experiencing prolonged degradation and range loss, followed by the installation of the very same crappy battery, will turn it in without a second thought. They will then get another brand of EV - or a PHEV.

Or those of us with long memories regarding our 24kWh packs... Mine is about to drop it's 4th bar in about a month, and the warranty expired 3 months ago, with 42,000 miles. If Nissan decides to pay for half or more of the replacement pack, I will replace the pack, upgrade my TCU, and continue with it for a few years, and not write Nissan off as a brand. However, if they tell me to pound sand, I will limp along with my Leaf until I get my Model 3 at the end of this year, then sell the Leaf for a pittance.
Pulled the trigger on going EV on 10/2016 with a 2012 Leaf SL, traded it in and now I'm a very happy Tesla Model 3 owner. Reservations for Tesla Model Y and Cyber Truck.

I have a long memory and I remember signing a document at the time I purchased my LEAF specifically stating that the car had no warranty against gradual capacity loss. IMO, the fact that Nissan later added such a warranty to address a product deficiency in that arena should not be held against them, particularly since they even extended the warranty past its written provisions for some customers.
