The problem is likely Nissan's air cooling system used for the Leaf's battery

The Nissan Leaf is a top player in the electric vehicle (EV) industry, but one major issue that sometimes plagues these vehicles is the battery -- and the Leaf's battey seems to be taking a lot of heat.

Leaf owners in Arizona have recently complained that their EVs are losing significant capacity in the desert's hot heat. In fact, Arizona Leaf drivers Scott Yarosh and Mason Convey have both testified to this claim.

"When I first purchased the vehicle, I could drive to and from work on a single charge, approximately 90 miles round trip," said Yarosh. "[Now] I can drive approximately 44 miles on this without having to stop and charge."

Both owners said they've lost about 30 percent of their battery capacity since purchasing their vehicles. Even when their batteries are fully charged, two to three of the 12 lights on their battery capacity gauge are out.

Both owners are very meticulous about how they care for their Leafs. There is absolutely no sign of abuse, as both were able to produce dealership service records with high marks.

"We want to learn more about what's going on, but it's something we've just been made aware of, and we don't have any conclusions yet," said Perry.

The problem is likely Nissan's air cooling system used for the Leaf's battery. Tesla CEO Elon Musk even predicted that Nissan's cooling system would fail the Leaf at some point back in August of 2010.

Musk said that Nissan's Leaf employed a cheaper air cooling system that would make its battery temperatures jump "all over the place," where cold temperatures would degrade the battery while hot temperatures would shut it down. Tesla, on the other hand, uses a high-end liquid heating/cooling thermal management solution.

But for those who are still avid Leaf fans, there's great news if you live in California or Washington. Dealerships in these two states are cutting about $5,000 off the price tag for a new 2012 Nissan Leaf. The MSRP is usually $37,250, but with the $7,500 federal tax credit, the $2,500 California clean-vehicle purchase rebate, and now the additional $5,000 off, the price for a brand-new 2012 Leaf is only about $23,000.

I don't see the point to spend millions on a technology that needs subsidies just to survive.
If you are not able - as Company - to survive on "open air", just forget it.
Prices of electric cars in Europe, are a lot higher, and business does not ramp-up.
As a matter of fact, Renault had to stop one of his production plant shifts due to lack of demand for the brand new (microcar?) TWIZZY.
In my country, people prefer to spend 12K Euro on a good 1.4 or 1.6 liter compact diesel than on a still complicated and expensive hybrid or EV.
You can get a really good mileage out of those cars and - of course - a unlimited range to travel.
They are reasonable clean and easier to maintain.
Just a question .... Why petrol cars instead of Diesel ?

Diesel cars are more expensive, smelly, and not as responsive.

Have you ever seenod driven a new EUROPEAN diesel car ?? It seems not.
They have more torque at low RPM, so far more responsive.
Smells and fumes are a thing of the past. With new particle filters and catalizators they are "almost" as clean as a petrol counterpart.
Have you ever stand at the back of an accelerating petrol car ?? They emmit a "rotten eggs" smell worse than any new diesel.
Regarding more expensive. Perhaps against a petrol yes; but far more responsive and less cunsumption.
I was comparing diesel price against Hybrid/EV prices. They are far far cheaper, and almost same mileage as a hybrid, providing you have a careful drive.
