The 2011/2012 Leafs had major problems with battery degradation in hot climates so much so that Nissan was forced to offer a free battery replacement. So I got it replaced for free. The newer battery is lasting better, but still not great. I think Nissan screwed up by sticking to passive battery cooling.
For reference I live in southern Florida so we have hotter than average climate.
