In the spirit of making things up.
Is "falling apart" a bit of an exaggeration? Maybe. Hardly made up or hyperbolic though. From Nissan's own mouth:
"Recent Nissan battery life data suggests that the battery itself may last some 10-12 years beyond the life of the car. The company sees the LEAF's reasonable life at about 10 years. Managing director of Renault-Nissan Energy Services Francisco Carranza reveals that the batteries in those cars seem to have a 22-year life span."

Nissan LEAF Batteries To Outlast Car By 10-12 Years
Some would argue otherwise, but this is fantastic news.

It is a Nissan after all, so falling apart is certainly a possibility.
