Out of curiosity, how many gids were you at in each of these states? I could care less about the % SoC Leaf Spy says.
It sounds like the behavior may have changed between gen 1 and 2. Gen 1 w/nav would most definitely give warnings on the dash and on the nav system (w/voice) at the same time when you hit LBW then VLBW. Those w/no nav (S trim) would only hear a beep and never voice. Also, on gen 1, IIRC, the GOM goes from flashing some value to --- miles at VLBW.
On 24 kWh Leafs, LBW sounds at about 49 gids and VLBW at 24 gids. The values are different for higher capacity Leafs.
I also have gone from 6% on the dash display to ---%. I never considered that as 0%. To me, it was it's somewhere below 6% but "all bets are off, so I'm not going to show you anything".
The video at https://www.edmunds.com/nissan/leaf/201 ... r-end.html
at 1:15 has them hitting LBW. This is before Leaf had a % SoC display. That didn't arrive until model year '15.
