The lizard battery(late 2013 to 2016 24kWh) is pretty good. If the 30kWh battery was similar, few would be complaining.

The problem with the 30kWh battery is different than the problems with early 24kWh batteries. Batteries, regeneration, charging and balancing are all fairly complex. The fact that simply driving more seems to improve lifetime suggests to me that a firmware change could make a large difference in battery life.

Not if the OEM can prove that Nissan's other electronics is shortening the life of the batteries.
