Is there any warranty support for a 2013 leaf with 72k and 7 bars. I heard somewhere that if battery drops below 8 bars Nissan would restore it to a minimum of 9 or replace.
The only remaining warranty on a 2013 Leaf is the battery defect warranty. This applies to bad cells only, not to capacity loss. The defective cell(s) have to be bad enough to trigger error codes.
