Have any 40’s lost a bar yet.
Maybe, but we haven't seen it documented yet. Cwerdna saw a Facebook post showing a 40kwh dash display with 3 bars gone, FWIW.
.
Why is the FB report not "documentation" ?

Just because Facebook is such a nest of liars. ;) There was a photo, IIRC, but I don't know how detailed it was, and they can be faked.

If there indeed is one, I like to see the leafspy stats that went with a 1 bar looser, 2 bar looser, etc
See if the leafspy SOH for 2018 means anything.

Anything is possible. Its not like it would be that difficult to torture the pack. People do it all the time. But I have a HUGE presence on FB and its not like I see everything but I don't miss much and I don't remember seeing this. I put some feelers out to people who are also very active in the EV space and its either "didn't see it" or no response so far.

What's your mileage though?

We are only around 1900 miles.
Almost looks like mileage doesnt matter.
My mileage is 2400. I don’t think mileage matters either.
Ok thanks. But our mileage is pretty close too. I'd be curious to see a 2018 with 20k miles.
In 4 days I will have had my '18 Leaf for 1 year. I just got home & the odometer reads 17001 miles & my car's SOH shows 94.33%

Do the SOH changes seem to correspond to a loss in range of the same magnitude?

Maybe. I'm down close to 10% I'd guess, and my GOM shows 130 miles more often than 150 now. I don't take 150 mile drives.
The GOM range number seems to be more affected by your current mi/kwh equation than the actual battery capacity to a certain point.

Case in point, even "missing" roughly 5% capacity I can still get the GOM to show 180 miles of range with a full charge when I'm averaging 4.6m/kwh or greater.

I'm not really surprised. Although the 40kwh GOM does seem to be better.

I dont know if it was this thread or another but I noticed the GoM takes into account whether AC is on or off but doesnt seem to care what speed or temp set point I used. I "guess" that's where the G comes in.

A/C or Heat as well as "Eco" vs std mode. The GOM show 2-7 miles of additional range depending on my SOC when I toggle the Eco button

I haven't used the heater yet, so that will be interesting to see what that does to range. I have the weather package though, which was suppose to be a lot better than without. I tried the seat heater and it felt nice, didn't appear to change the GOM.

The nice thing is, since we only put about 20-30 miles per day I never really need to worry. I've noticed that when I drive I averaged about 4.1 miles / kWh and when my wife did she averaged about 3.75 miles / kWh this summer. (someone might be a lead foot!) But that's still a lot better than my truck or even our outback. Even if she cranks the heat up this winter I have to believe its still a lot better than getting 13 mpg in my truck or 23 in the outback. Our outback was suppose to be 32 highway 24 city but around town it never gets much above about 23. And that is a 4 cyl.


Checked my data this AM and my HX has started to drop. Noticed my average battery temps now in the low to mid 70s instead of mid 100s this summer.

I have the SL so we have the same "HVAC" system. The heat pump seems to be similar in efficiency in either temp direction however winter temps are a much greater temp differential than Sumer temps relative to our skin temp so the power draw is roughly double in winter vs summer although seat & steering wheel heating can mitigate that spending on your clothing choice & tolerance level.

To be honest your consumption for both of you is on the high side so the HVAC consumption will be smaller chunk of total energy consumed but you daily range needs are so small it's immaterial.

For comparison I get 4.8-4.9 in the summer & around 3.7-3.9 in the winter and of course in between in spring & fall. Any chance your tire psi is at 39 cold?
