Question 1

Weak 12V auxiliary battery (40 kWh)

Accepted Answer

On electric and hybrid vehicles the 12V auxiliary battery powers the start-up electronics; when it weakens, the car may not go into Ready mode, show random warnings or refuse to charge. It is more common with infrequent use and after 4-6 years.

Question 2

Slow rapid charging when the battery is hot (40 kWh)

Accepted Answer

Without active battery cooling, the Leaf reduces rapid charging speed as the battery heats up, so a second or third rapid charge on a long journey can be much slower ('rapidgate'). Software updates eased the problem but did not remove it.
