4-6 years checks out. Our original 2013 LEAF 12 volt aux battery failed
at about the six year point, so we got the max of that range. We also
still have 12 bars on the main pack at about 65k miles.

Why is Lawrence replacing his 12V aux battery?
If I remember correctly, he traded in his old gen Leaf
for a newer (2017?) 30kWh Leaf. That would only make his
12V aux batt 3 years old, which should last from 4 to 6
years.
The OEM 12v Aux battery that comes with Leaf's are a common early
failure point. I had to replace mine at 4 years when it started to
corrode and had blue & white crystals escaping....

It does not surprise me that one has failed at the 3 year mark.
I went with an AGM replacement battery and am hoping it will last 4-6
years.
