Could it be that the first bar is 20% and the next 3 bars are 5% each? That would give a 4 bar loss at 65% which is close enough to the 66% you would expect for the loss of 4 bars out of 12. Also the 20% loss of capacity is what Nissan expected at 100000 mi. So the car would have all twelve bars up to the end of the warranty period if the battery held up as expected. Then the last 8 bars would be 8% each. Or it could be that first bar is 20% and the next 11 are about 7% each which is more likely to my mind. Who knows how Nissan has programmed them. Time will tell. I'm expecting a replacement battery by next summer at this rate. Have there been any reports of a 3 bar loss yet?
As far as the capacity bars go, I agree that they're nearly useless as indicators but they are incredibly important as far as the warranty goes. That's the point of the discussion here. The warranty is based on the loss of 4 bars and Nissan has not defined what that value actually is. So we get to play a guessing game based on our observations.
Someone has already lost 4 bars on their 2016 30kwh leaf.
