2015 S, no bars lost.

Car was exported to Finland, has been here for 2 years. I'm expecting it to last a long time. It's so cold here :(

Adding your location to your signature is helpful. ;)

This guy in the mild climate PNW has hit 125K miles on his '15 Leaf and still has all 12 capacity bars: https://www.facebook.com/groups/seattle ... 259555264/.

Is your local climate humid, or more dry? Dies it cool off much at night in Summer?

Monterey Bay should be a very mild climate.

I didn't mean temperature extremes. I mean average and common humidity levels and nighttime temps. I speculate that the car wasn't cooling off enough because of moist air retaining heat and keeping overnight lows above the point where rapid pack cooling starts - below 68-70F. This would be worsened by a non-cooled garage...

...Nope. Temps in August fall into the low fifties. Interesting. High SOC, maybe?

I suspect sustained high SoC. Yes.

That is the key. But even if owner lives on the bay, the temperature averages just 10 miles inland can be quite extreme. Low mileage and "higher" temps and high SOC is the likely culprit.

If we look at super long range LEAFs, the big key is higher than normal usage which implies charging to full and immediately running that charge down. The 125,000 mile LEAFer admits to only charging to full just as he is ready to leave, charging to 80% or less as much as possible.

I also think that fuller cycling of the pack regularly helps the BMS maintain accuracy. My 2018 has lost enough that I am projected to get a new pack well before 100,000 miles but I am driving a lot less so cycling is shallow and I have huge doubts my BMS is reporting accurate information.
