100% charge but only 65 mile range

[evsoulkia]

I took my 2016 ev into the dealer. They did several recall updates and software updates. When I left the dealer I was getting around 100 mile range at 100% charge. Each day that went by the range kept dropping. I'm now back down to 65 mile. I'm back at the dealer. I'm guessing from reading other posts that at 36k and living in ca I'll need a new battery.

This is indeed the most likely scenario.

I wonder whether your battery actually delivers just 65 miles range with 100% battery or that your GOM-range shows 65 miles with 100% batt. ?

My '15 Soul-EV GOM-range initially shows 86 miles with 100% batt. (0.86/%) , but I actually get 70 miles using 57 % batt. (1.22 mi/%).
I think I have a bad GOM or ?

GOM not matching the actual range is just that it needs to learn how you are driving the car.

Actual range (regardless of what the GOM reports) being a lot less than it should is a bad battery. Normally as the battery goes bad and the actual range decreases then the range shown on the GOM reduces. A BMS reset clears all the counters and will cause the GOM to show a normal range for a while until it relearns how bad the battery actually is.
