https://www.facebook.com/groups/nissan.leaf.owners.group/permalink/1744888885581945/ has dashboard pics of a '12 Leaf imported to Colombo, Sri Lanka from Japan which at 176K km shows it's down to 3 (!) capacity bars, So, it's a 9 bar (!) loser. I think this is a record for me, so far. I don't recall hearing of any that are worse than this, yet.
If https://en.wikipedia.org/wiki/Colombo#Climate is accurate, that is a pretty unkind climate to Leaf batteries.
I assume the car spent more time in Sri Lanka than Japan.
