This was probably the reason. As a test I turned it off and it is now 100%.
But I could have sworn that it was on with my old Leaf and that it was always 100%.
I had thought that if it is plugged in it would just draw power through the cable instead of the battery to do climate control.
Also I...
I just bought a new 2015 Leaf and it stops charging at 98%
The charging lights on the car have stopped flashing at that point too.
I had a 2014 Leaf for 2 years and it always made it to 100%
Is this a problem?
I am quite disturbed by it.
