I am getting new tires tomorrow since the OEM's are down to the markers. That is not many miles for Michelin tires in my view but I know the leaf is heavy.
Lots of folks have gone through the original tires in a short time. The Leaf is a heavy car but the original Ecopia tires wear quickly. The replacement tires will probably out-perform the OEM tires if they are a good brand.

I think the person who had leased the 2016 Leaf for 3 years only used the OEM L1 perhaps based on the 740 recharges averaged out to occur every 30 miles of driving. At first it only reported a range of 72 miles when fully charged. The with deep recharges on the L2 charger it reported as high as 95 miles but that would drop by about 3-4 miles for every actual mile driven. Now a 100% charge shows a range of like 72-84 miles but seems to be without any real meaning. Not sure how it popped to 95 that one time.

You are GOM'd.

Read the kWh from LeafSpy in relation to SoC.

Even the aftermarket version of the OEM Ecopia tires will outperform them. They are pretty well liked - especially compared with the de-rated OEM version.

If your problem was bad cells, you wouldn't be showing a loss of capacity bars - just a huge drop in range as you drive. (Not just the usual self-corrections of the inaccurate range estimator.) You do need to have the software patch applied to get a new battery, but that doesn't usually restore more than one or two bars, IIRC, and your range seems to indicate a genuinely degraded battery.
I expect you are correct. Actually all my cells seem to be in tack voltage wise. This morning they averaged 4.085 volts each and that is a new development. I guess I will try to find a dealer that can service the Leaf. Nashville may be my best bet since I live 3 miles into KY from Paris TN.

My first objective was to learn about my battery and Leaf Spy Pro before turning the car over to Nissan techs to do the software patch. If the battery is failing I need to get started on the paper work after I lose another bar and get the software update ASAP. I can use another 30-40 miles of range. :)

My battery management software has not been updated as far as I know and still is very flaky. Range at 100% SOC normally is around 70-72 miles. This morning at 100% charge the reported best guess range was 95 miles. In the first 10.5 driving miles today the range estimator had dropped from 95 to 65 miles. Yesterday the meters was more more linear. This happened a couple weeks ago with the same drop like a rock actual results. Does anyone know the variables the computer is using to get these wild swings of the GOM?

Now I know turtle mode reduces power to motor in a major way. I kept driving after I hit 7 GID's up and down the steep hill to my house. At WOT up the hill on the last run it was like the car had died but it went back to pulling when the speed dropped to about 30 MPH and the Leaf Spy Pro reported 5 GID's at that time.

Total range at a reported 72 mile range and the 95 mile range estimate was 60 actual miles with the same electrical load for comfort in winter driving. While it is recharging now yesterday I used 20.5 kwh of at 240 volts drawing 26 kw max to get back to 100% SOC reading.

SOH starts out at 64.5% when SOC is at 100% and GID's report being at about 65% at the same time.

While there was no regen in reverse I saw greater Regen values in D than in B mode. In B mode I never saw more than 30 kv even braking hard. At about the same speed and braking pressure I did see 40 kv o Regen in D mode however. Those values from Leaf Spy Pro surprised me. B mode does give a more single pedal driving feel and I try to drive without using the service brakes as much as possible like in the straight shift days.

I want to next try some DC charging at Walmart. Some have reported gaining a bar after using the DC charging port option. Since a 60 mile actual range works OK for our needs at this time I am very happy with this 2016 Leaf SL. If range does not change I plan to go for the software update that is go give back the full 107 miles expected range if the battery is actually healthy.

I found this video helpful in that he used about 22 kWh to add a range of 91 miles.

If a range test shows a degraded battery then the BMS update will likely add a little range (by using more of the available charge at the "bottom" of the pack) but I don't think it will restore anything like full range. The update doesn't do anything Magic to the pack - it just re-calibrates the BMS and tells it to estimate capacity a bit more optimistically. So I'd expect a nine bar Leaf to go to 12, then drop back to maybe ten bars. The good news in that case would be an eventual warranty battery replacement.

https://www.facebook.com/groups/nissan. ... 682389451/ (private Leaf group, unfortunately) is a 4 bar loser on a '16 SL. He mentions it's his 2nd 4 bar loss. 1st time, he got the BMS firmware update which "fixed" things, temporarily.

He says "the GIDs at full charge are 223 it is pretty stable and varies by less than 5 GIDs." and "SOH was 62.61% at the time of the 4th drop". He's in the Phoenix metro area.

If these 30 kWh batteries are this bad (in general) in Phoenix, those folks might receive 2+ replacements within their capacity warranty.

I guess this is #2 I know of. Will restart a list later tonight/this weekend.

Did he mention if it went back to 12 bars with the update, or to fewer than that?

No, not in that post, but luckily FB search worked and I found his previous post at https://www.facebook.com/groups/nissan. ... 865412111/ from June 25, 2018. He hit 4 bars back then, received the firmware update which turned his 4 bar loser into a 1 bar loser before it became eventually became a 4 bar loser again, probably today/this week.
