Re: 2016-2017 model year 30 kWh bar losers and capacity losses

Any thoughts of why SOH bars would drop from 8/12 to 6/12 in less than 2 weeks?

A BMS "re-learning" the actual capacity after a reset would do that. Did you have thee BMS "update" from Nissan? That involves a BMS reset. You might get 3 or 4 bars back immediately, but you will then likely lose at least one or two over the next few weeks and months. You could lose all of the ones originally missing.

Nissan Leaf customer service said BMS was reflashed about a year ago. It has been at dealership for two weeks. When they started checking it it was at 8 bars and are concerned there is something else besides the bad battery since it just dropped 2 more bars since they got it into the shop.. They got a new Leaf system recently and my leaf is the first one connected to it. Since they are only 75 miles from the factory they are going to get a factory rep to the shop next week to check out charger, inverter and motor. I told them to use my Leaf so they can get trained on the new diagnostic system. With all of the flooding I am driving the Forester anyway.

FYI: I lost my second bar today. 2017 Leaf. Has just under 15k miles on her. I live in Phoenix area, but she gets parked in a garage overnight and I have covered parking at work. Ive never quickcharged (Chademo) her. I live close to work, so typically I charge 1x-2x per week. In the summertime, I also try to charge only at night if possible.

You're not doing anything wrong. Nissan's quality control and basic pack design are the culprits. The good-ish news is that you will likely get a new pack in a few years. If you are still in your hot locale then, I suggest you sell the car.

Feb update. 316 GID's 68.96 AH, SOH=86.76%, Hx=66.33%, 75049 total mi. 30120 mi on new battery. 20 DCFC and 579 l2 charges on the new battery. The battery is continuing to slowly degrade. In the cooler weather, I still lost a GID last month. I'm down about 13% from new. 20 months in, the old battery was down 21%, so the new battery is doing better. The difference is notable and I expect to hit the 100K warranty limit well before the new battery would qualify for replacement. I still expect to be down about 25% at 100K. I expect that as the weather warms up deterioration will accelerate again. I'm looking forward to Tesla's battery day announcements and the reveal of the ID4 at the Chicago Auto Show. Fenix power is still a no-show at this point.

My OEM 30 kWh lost at the rate of 1% per month over 38 months after being sold new so I think your last battery is holding up much better than my first on. I still have not heard from the dealership other than they did not want to do the swap and thought doing a buy back might be better for Nissan. They finally told me they had never replaced a Leaf battery but had done a few BMS updates.

Thankfully the National Leaf Rep thinks Nissan standing behind their written battery warranty is what should happen so we will see what happens but they have only had my Leaf since 30 Dec 2019. At least last week the National Rep called me and did state they are using the 40 kWh batteries to replace failed 30 kWh batteries so I am wanting them to get moving because I left it expecting a 30. Maybe them dragging their feet was a good thing after all.

The new battery is better than the first one and fact is behaving just about as well as I expected the original to. At the current rate, I expect the new battery to last about 75,000-80,000 miles which is what I was expecting from the original battery. I fully expected the battery to fail under warranty at 70,000-90,000 miles. A replacement battery would get me out to 150,000 miles and I could write off the car at that point. If a new battery was cheap enough, I might replace the battery again or more likely buy a new and improved model. A used Model 3 might also be a possibility. Unfortunately, my first battery crapped out at 45K and the current battery will outlast the remainder of the warranty. If the battery had matched Nissan's goals, I would have had 80% capacity at 100K and could have driven it to 150K easily. Silly me for believing Nissan.

Good luck on the 40 KWH battery. I expect that it will actually go 100,000 miles. Between the larger size and improved manufacturing, it ought to be more much more durable.
