Nissan Leaf Owners Report Loss of Battery Capacity
All the affected cars were from Arizona, and experienced ‘the loss’ after the Leaf had been driven for between 21,812 km (13,633 miles) and 27,200 km (17,000 miles). The owners filed complaints with Nissan, and the manufacturer’s official response was “We’re aware of a few isolated cases where a very small number of consumers are reporting a one bar loss. (We’re talking less than 5 units versus the 12,000 on the road in the U.S.).”
Despite the fact that ‘the loss’ is to be expected, it cannot really be predicted as it is not a linear process, and according to Nissan, batteries encounter higher loss early on in their operational lives, with the curve flattening afterward in a more linear fashion. “Our internal results indicate that the battery will have 80 precent of its capacity under normal use after 5 years, and 70 percent after 10 years,” according to Nissan officials.

So there must be specific conditions that make the Arizona Leafs loose capacity.
Also wait for Tesla customers to have similar complain later.
but the big problem with the Tesla is the cost of their large battery pack - probably around $45,000, although current prices of their 3.1ah 18650 Panasonics indicate over $12 apiece - the car uses around 7700 of these , for a retail over the counter cost
of more than $90,000. Tesla must pay about half that amount, which is probably near the cost of manufacturing. They still are completely impractical, in an economic sense- that car will cost almost 50 cents per mile to operate. Tesla also lied thru their teeth about recharge times - they are twice as long as they were claiming a year ago - now they won't even state how long a full recharge takes (apparently Tesla has never done a full recharge using their supercharger. yeah,right).
thermal management system cannot keep their batteries at the low temperatures where capacity losses are least significant. And as to fast recharging, MIT researchers months ago reported that speed of recharge had no effect on the health of the li ion batteries they tested. Nissan's warnings about fast recharging I simply don't believe. Isn't it grand that companies who seem to know very little about batteries are out there building electric cars?
