Defective by design. Still using essentially the same battery pack they designed in 2008 for the 2010 LEAF -- no cooling system whatsoever, emergency resistive heater that keeps it from freezing but doesn't otherwise warm it, obsolete CHAdeMO charging port -- just with more capacity. They had their first class action lawsuit about unacceptable levels of battery degradation in new LEAFs in 2012, yet didn't change the design, just the warranty. The larger packs are now having high defect rates for cell-level failures. They are only able to sell a few hundred of them a month in North America for good reason.
