I just bought a 2016 leaf. Supposedly it gets 86 miles to a full charge in the city and 124 on the highway. After having it for two days and charging it twice I notice that the maximum miles on a full charge is 73 miles. I’m wondering if there is a problem with my battery. Is it in accurately showing how many miles I have? Is it a matter of battery degradation over three years? Or is it something else? Do I have a lemon? Prompt answers would be most helpful as I may be able to return it if there is a problem
