Studies have shown that most major breakdowns occur after the warrantyperiod expires, and that in most cases, the repairs cost "about the same" anyway.
The intent of this warranty is to provide consumers with confidence that despite this normal battery capacity loss, they will be assured of a minimum level of capacity throughout the warrantyperiod.
For LEAF vehicles whose batteries have fallen below nine bars during this period, Nissan will repair or replace the battery under warranty with a new or remanufactured battery to restore capacity at or above a minimum of nine bars.
