Short answer - no.HI my max kappa value is currently is showing 13. my I3 is a 2015 model. Do you think BMW will honor the warranty just based on the kappa value alone. So far on a good day, the max mileage on a full battery is 55 miles.
The battery kappa is a 'guess' using an algorithm that calculates the kappa based on conditions at that time. It changes.
Is yours a REx or a BEV? Makes a difference. REx stated mileage is 71, BEV 83. Using 55 as your mileage you are at 76% if REx and 67% if BEV, but the only way BMW will entertain a warranty replacement claim, is if they fully test the battery, which entails draining the HV pack to zero, then measuring the charge it takes to take it up to 100%.
Is your mileage consistently low? Mileage changes according to driving style and temp. On days when the temp is 100+ F (so the AC is working hard full-time), and I drive a little aggressively, my range - 2015 REx - can be as low as 55. Below 80 F, and drive a little more sedately, and my range will be 70+.
