The 2012 Nissan Leaf

Nissan Leaf owners in hot climates experiencing battery problems

2012 has been one of the hottest years in American history and while that is only a minor concern to most owners of newer vehicles – Nissan Leaf electric vehicle owners in US areas with extremely high temperatures are reporting vastly reduced battery mileage.

The original report came from a CBS affiliate in Phoenix Arizona who spoke with two proud Nissan Leaf owners who went from loving their electric car to being very frustrated with it. The cause? The vehicle has had a massive reduction in the battery capacity when driving in very high temperatures. Nissan claims that the vehicle can go around 100 miles on a full charge and one of the owners interviewed by CBS5 in Phoenix stated that during his first year of Leaf ownership, he was easily able to make his daily 90 mile commute on a single charge. However, that same owner claims that during this, his second summer with the Leaf, his battery range has plummeted to a very disappointing 44 miles – and he isn’t the only owner dealing with this problem. Nissan has allegedly received 5 complaints of similar battery power loss during this hot summer in Arizona alone. You can watch the full video segment from CBS5 below.

A quick tour of internet enthusiast sites like shows that Arizona owners are not the only ones dealing with this problem as Nissan Leaf drivers in Texas and California are also reporting substantial losses in battery capacity during their second year of ownership. Nissan has asked that owners with these problems take their vehicle to the nearest dealership for evaluation and that owners should be certain that the dealership service department contacts the regional Nissan representative to report the problem.

That means the next Leaf version will have a very active temperature management system. Ah, the caveats of first version and early-adopter life.
HA, what a pisser. poor quality foreign cars, what a joke. I hope this nasty assed company goes UNDER, BIG TIME
Bummer. I was just about to buy a Leaf so I could drive to the coffee shop and sit not talking to anyone tapping on my MacBook and sipping a soy chai. Now what am I gonna do?
buy a volt!!!!! Duh
buy a volt!!!!! Duh
Buy a preius!
I graduated from a renowned battery prpgram, and I can tell you it is expected for the Nissan battery to lose capacity rather fast, especially in hot environment, even the Chevy Volt will lose capacity over the years, though slower, I will not buy Leaf, nor Volt, fearing the degradation of the battery. In the case of chevy Volt, people has a tendency to make the battery fully charged whenever possible, expect your battery to lose capacity sunstantially after 3-6 years.
If that is your considered opinion, what would you suggest as the most ideal charging scenario for the Volt? Deep cycling? or exercising the full range of the battery? Do you suggest allowing the battery to maintain its own thermal state and decreasing the range in hot weather over allowing the system to use current from the plug in to maintain battery cooling.Please offer your opinion more specifically.
