Do remember that this is the BMS's (Battery Management System) estimate, and the BMS isn't very accurate at estimating capacity. It can be off by 10%, and maybe more. Why do I say that?
My current estimate is that I have about a 10% loss, with 38000 miles on my 2014. I base my estimate on recharging power, range at known speed on a round trip with little wind, and so on. At times the BMS has agreed. However, my driving/charging varies a lot. So I get to see some more interesting estimates from the BMS than perhaps most people do.
My Ahr has been as low as 57.8. My SOH has been as low as 88% My Hx has been as low as 87.35%
My BMS showed zero loss on 11/20/2017. Ahr= 65.64, SOH= 100% HX= 100.59%
BMS yesterday showed this(11/29/2017). Ahr = 61.60, SOH= 94%, Hx= 94.91%
Gee, 6% loss in 9 days. Should I panic?
