degradation, isolation, battery percentage suddenly drops then recover. etc. in brazil they said nissan cant change the whole battery pack, only repair using parts. the total costa of the repair will cost about 60k dollars. they said they cant fixit at this price, probabbly they will buy it...
I have a 2019/2020 black leaf tekna 40kwh. I bought it on december 2020. After 121.000km I had some battery issues.
I take some photos of the open battery pack.
