We did have a pretty hot summer this year (hit over 110 a couple times) and I wasn’t able park the car in the shade. The highest I ever saw the battery temp was 7 bars and that was about 3 times.
The above didn't help.
Also, the temp bars are crap, with huge overlapping ranges: http://www.electricvehiclewiki.com/Batt ... ture_Gauge
. You can get the real temps from the sensors via Leaf Spy.

Hot Summers and plain old age take a toll.
Probably yes on the first. The previous person may not have cared too much about preserving the life of the battery nor known the proper steps nor monitored pack temps w/Leaf Spy. If they were leasing w/no intent to buy.... there's not much of a reason for many to care.
My 5/2013 built '13 Leaf which was previously serviced in Santa Clara and registered in Saratoga (that's about all I know) that I bought used in July 2015 still has all 12 bars but is creeping towards losing 1. Fortunately, during hot weekdays this past summer, I was able to keep the car in the shade and usually either in a cooler underground parking garage or slightly undergound portion of the parking structure near my current building @ work. From what I can tell from ambient temps and battery temps, it can stay below 80 F there even when it's 95+ F outside at ground level.
My own stats as of last night:
Hx: 82.52% (I've not seen Hx get down to 82.xx% until real recently)
odo: 48,735 miles
QCs: 0 (mine has no CHAdeMO inlet)
L1/L2s: 3172 (yes, this has known quirks and I do use the 80% timer w/midnight to midnight trick)
I'll be surprised if I still haven't lost a capacity bar before May 2018.
