I don't have any actual numbers, sorry. I just remember being warned to be careful about cars from hot climates (like southern europe, and some US locations) a few years ago when I was looking for a used Leaf. Demands for EVs were very high in Norway, and resellers had to import (and still do) used EVs from other countries. I found a life expectation chart for 3 US cities at [0]. It's well know that high temperatures (while in use and while in storage) degrade li-ion batteries[1]. However, electric cars have thermal management systems to try to protect the batteries from this effect (extreme heat and cold). Tesla have active water cooling, while Nissan Leaf use a simpler air cooling. They also use different battery chemistries that handle temperatures differently. If you have a look quick look at this talk[2] you'll hear that Nissan is using a chemistry that experience higher degradation under high temperatures than for example Tesla's choice.
