Unfortunately, he didn't provide any other info.

I average 4.2mi/kwh. Happy to get a picture of that at some point. This is my second Leaf, after I had a 2011 SL. I drive it very conservatively, always in B ECO, and when coasting I shift into N and let it roll along as much as possible before applying power again. I have my tires at 42psi as seen in my screenshots.
I will try and get screenshots at LBW and VLBW and post here. I don't know what the dealership is going to say today, but I'm sure I'll get it back while Nissan decides what to do. I'll update as I know more.
DaveinOlyWA said:sounds like you are doing everything right. what is your average daily mileage? Sometimes if its too low that will depress stats but not to the point of losing bars. Right after I got mine, I went 2 weeks with very little driving with half the days at under 10 miles, charging it just a few hours every few days or so and it dropped to 98% SOH and 81.17 ahr. Due primarily to my wanting to see where the numbers would go and also a slow time at work
But when things picked up, this included several fast charges (about half the days it was 2 charges a day) and stats went back to new 100% SOH, 82.34 ahr.
I used to live in Marina so pretty familiar with the climate you have and I have to think most of the damage was done before you got the car. Another reason why I won't get a LEAF without plugging in LEAF Spy first and always select a car no more than 2 months off the factory floor. On my 2016 S 30, I got it on Veteran's Day. For the uninformed, my version started on the factory floor in Oct.

My Leaf SV was one of the first builds too and my battery isn't doing so well either, down to 92% SOH 26kwh 72ah with 13k miles
I think Nissan made a tweak to the batteries which explains why nobody outside of the first released 30kwh Leafs are reporting degradation issues.
armelwani said:Got my car back. No surprises here, they say the battery is JUST FINE!!! Completely within spec, they say. They won't replace it until 4 bars are lost or it throws a code. Just... incredible. I am absolutely dumbfounded. I will be continuing to document my battery readings here for everyone to follow the degradation, and I will be calling the EV hotline DAILY until they're so sick of me that they replace my battery.
I think that there's a buffer hidden in the software for the BMS that limits the GIDs value to a max of 363. Therefore GIDs don't start to drop until the battery drops below 78AH. That gives Nissan about 6-8 months before there's any indication of loss of capacity unless you check the AH and SOH values. If you have a late build 2016 or a 2017 with an 80+AH battery, you might not see anything wrong for up to a year. Nissan obviously knew there was a problem because they have switched to LG Cells for the 2018's. They spent a lot of money to build a new battery plant in Smyrna TN which they have effectively abandoned if they are buying LG cells now. You don't do something like that unless there's a big problem that you can't fix.rcm4453 said:I wonder why this would even happen after they seemed to have gotten the chemistry right starting with post April 2013 builds?!?
One would think the 30kwh batteries would pick up where the 24kwh lizard packs left off, not go back to the crappy 2011/2012 chemistry!
I don't think 2017s were affected as much, seems to be batteries built end of 2015 that are degrading faster then normal.

My commute alone is 20 miles round trip, but I work in IT and travel to client sites pretty regularly. It's not unusual for me to have a 100 mile day and do a couple charges in the same day. I seldom have a less than 30 mile day, so usually charging every other day from about 30% up to full.
I always list as being in Monterey because it's easier for people to identify where that is, mostly because of the Aquarium, but I actually live in Marina. Where/when did you live when you were here? For a little added perspective of my driving habits, my HQ is in Ryan Ranch and most of my clients are in Salinas, so I'm back and forth on HWY 68 very regularly.
johnlocke said:Just passed 25,000 miles, after 15 1/2 months, I'm at 306 GID's fully charged, 67.03AH, SOH = 84%, Hx = 77.77%. 39 QC and 461 L2 charges, Cell balance is 9mv at full charge. It's looking like I'm still losing 4-5 GIDs/mo even during the winter. I'm expecting the summer to be worse and that I'll be down to 260-270 GIDs by August. That's essentially a 24KWH battery after 20 months. I'm Sure that Nissan will say that's within spec. I expect to have to replace the battery in the next 12-15 months at about the 45,000 mi mark.
Build date is 10/15. Delivery Date was 12/15/15. Lot time was probably less than 2 weeks. I wasn't planning on buying that day since I was looking for an SV with cloth seats but ended up with a loaded SL anyway.DaveinOlyWA said:johnlocke said:Just passed 25,000 miles, after 15 1/2 months, I'm at 306 GID's fully charged, 67.03AH, SOH = 84%, Hx = 77.77%. 39 QC and 461 L2 charges, Cell balance is 9mv at full charge.
