I drive a 2016 Leaf with the 30kwh traction battery. It has become obvious
the battery is degrading rapidly, and that I may end up dealing with Nissan
to get a replacement under warranty. I have seen conflicting information
on the web saying that owners should contact Nissan even before the battery
drops to 8 bars. It's not clear to me why that is necessary, so I thought
I should ask questions here.
The condition of the car is: I bought the car in Sep 2019 at 29K miles. The
battery had 12 bars. By 35K miles, the battery had dropped to 10 bars.
Applying the software "fix" for the 30kwh battery restored the bars for a
short time, then they disappeared again. By 44K miles (March 2022), I noticed
the battery was down to 9 bars. It seems likely the battery will drop to 8
bars within the next year, at which point I will have to deal with Nissan.
I am aware of the article in insideevs.com which documents that the 30kwh
battery degrades three times faster than the 24kwh batteries. It is also
clear that the software "fix" is a smokescreen; these 2016-2017 30kwh
AESC packs just have poor battery chemistry. (I don't believe passive cooling
is the main problem. I don't live in a real hot climate, and the battery
temp gauge has never gone above 3 bars from the bottom, while I have owned
the car.)

If you have dealt with Nissan on this issue, I would like to know:
1) If there is any point in contacting Nissan before the battery drops to 8 bars.
2) If you had Nissan do warranty work on your 30kwh battery, did they attempt to
replace cells in your 30kwh battery, or did they install a replacement battery
pack of 30kwh or 40kwh?
3) If Nissan did not replace the 30kwh battery with the (more reliable) 40kwh
pack, did they offer you a 40kwh pack for an additional charge? Just for grins,
I had a Nissan dealer run a load/capacity test on the 30kwh battery. The dealer
declared the battery was below spec, and that a 40kwh replacement before
dropping to 8 bars, would cost $13500.
4) I was provided a statement by Nissan at the time I bought the vehicle,
stating that the warranty on this used vehicle was 7 years/100,000 miles
from date of sale, and that warranty expires on Oct 1, 2023. Has anyone
had problems with Nissan refusing to honor warranty on a used vehicle?
