Failures below spec are eligible for warranty replacement.
Replacements are with the so-called "Lizard" battery pack, which is
reported to be more tolerant of hotter climates.
I know from personal experience that Nissan has been less than honorable
in dealing with battery warranty issues. Their instrumentation
obfuscates the true situation. IMHO, that is by design. "Bars" have
almost no meaning. The car owner has no idea what true battery capacity
is other than by observing declining range. Nissan uses this dearth of
owner accessible information to deny capacity loss.
Even if honored, the warranty is nearly useless. It specifies at least
30% capacity loss (as determined by Nissan). By the time a Leaf is 30%
down in capacity, it has lost almost all of it's utility. And it seems
likely that Nissan is forcing owners to suffer to 40% or 50% loss before
warranty replacement.
My Leaf went from about 95 miles of range down to about 65 miles. With
65 miles of range, Nissan declared my battery to be "fine" and refused
to replace. For the first year, my Leaf served about 90% of my needs.
With 65 miles of range, it was less than 50%. I went from being able to
drive the Leaf about 15k miles per year to way less than 10k miles.
With such crappy range, the car was not worth keeping.
I bought the Leaf with the expectation that the battery would serve for
at least five years and, when it was time for replacement, cheaper and
bigger batteries would be available. I found it to have a two year
battery with no warranty protection.
I was extremely happy with my Leaf. For the first year. I'm at two
years on the Tesla and still extremely happy. The Tesla has gone 50k
miles in two years and has lost about 5% of capacity. Tesla
instrumentation is honest and clear, much in contrast to the Leaf's.
