... Nissan didn't consider battery degradation to be a problem, just cell failure. It seems this 30kwh issue and the earlier hot climate issues on Gen1 cars really took them by surprise.
Nissan still does not consider drop of SOH to be an issue. Nissan NZ recently issued an official report on a particular Leaf with allegedly dropped SOH and have not found that particular car battery to have any issues.
Would be interesting to know what is Nissan NZ' criteria/threshold to consider any claims for this combination: 24/30kWh & ODO & Manufacture Date & SOH.
