Nissan Leaf Battery Can't Take Arizona Heat, Dealerships Knocking $5,000 Off Price

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.

Back in the early 90s' we took our EC-130Hs up to Eielson AFB to teach our crews and maintenance guys how to keep the birds flying under extreme cold weather conditions. At the time it was well below -30F with the windchill.
Always remember seeing a maintenance guy stationed there striking this black rod about 3" round and a couple off feet long on the pavement. Little chips would break off and he'd gather them up in an old coffee can. Then he places it over on the exhaust manifold of a Aircraft start cart. We asked him what he was doing and was floored when he replied; "Thawing out some axle grease!"
Later on they even demonstrated how a heavy piece of steel became brittle from the cold. Guy struck it with a mallet and the thing fractured almost like glass.
I know this isn't quite on the tread subject but just wanted to add to your post that there are a lot of other factors to keep machinery running in the extreme environments. But even down here in the lower 48 weather can get down below -50F in places like Yellowstone.
