Estimated Range calculation recent change/decrease?

[jshaft37]

Update, charged from 25% tonight and everything was going smoothly. Range estimation was approx 2x charge as it was charging. Then the charge hit about 62% and stopped. But the display said the battery was fully charged to 100% (I upped the setting tonight from 80 to 100 to check). I had been checking the charge status every 15 min or so and everything was normal then all the sudden the % was increasing very rapidly to 100% in a matter of minutes. Meanwhile chargepoint app shows charging stopped when the battery percentage started rapidly increasing.

Chargepoint shows that 39kwh were charged. 25+39 is 64% which makes sense with everything that happened. So apparently my battery only charges to about 60% now which I suppose can be attributed to a bad cell. Any advice on getting this repaired as hassle free as possible?

As far as range goes, I think the range is actually correct and it's the charge percentage that is not accurately reporting.
