Until we have real world data over a year or so, we have no idea how the firmware change really affects battery life. This is especially true since Nissan hasn't released any details over what the problem was or how it was fixed. Just "trust us, we took care of it" from Nissan. Even this much had to be reverse engineered by the guys in New Zealand and they only did it because Nissan won't support the Leaf there.
There is no real data that I've seen to suggest that 30 kWh batteries are really failing faster than expected. There is dynamo tests, range tests and recharge tests showing that at some the tested batteries are doing OK.. 2 years into their life.
Remember that the test of time... requires time.
Do read the articles behind the picture. Do read the text behind the caption. Do notice that they tested cars, getting real world data, not just "trusted Nissan". Do notice that Nissan will now provide this firmware update in New Zealand, which sounds like at least limited support for the Leaf.
I expect rather than just telling me you don't trust Nissan, someone might find some more actual data based on physical measurements. Not BMS estimates. Not FUD from Tesla fanboys.
Is that too much to ask?
