Question 1

Weak 12V auxiliary battery (24 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

Traction battery capacity loss (24 kWh)

Accepted Answer

Early Leaf batteries without active liquid cooling lose capacity faster, especially in hot weather and with frequent rapid charging. Owners see fewer capacity bars on the dash and a noticeably shorter range.
