Recall R24B2: Battery State of Charge

[fuse]

Back to the recall, it's for 2018 to 2020 Leafs. Apparently 2021 and later years aren't affected? That's weird... Did the charging algorithm actually change on the 2021 models?

2018-2020 of a particular battery type or model, or all of them?

2018-2020 of a particular battery type or model, or all of them?

Seems to vary... it's not clear why.

My VIN shows the recall.

 

[Chad E. Mo]

The Car Guide reports it will be a software patch.

Unfortunately not. From what I've read for this recall, Nissan will only apply a software patch.

I have a 2018 SV and when I plug in my VIN it tells me there is no recall. I wonder if that a fluke cause it did not show the backup camera either and I got the wiring harness replaced as a part of that recall.

Me too; my 2018 SV does not show up in the recall when I plug my VIN in.

The recall notice in post #44 clearly shows that it only applies to model years 2019 2020. Did you not take the time to read it?

I did read it; I just plugged my number in anyway because it took 2 seconds. But I keep seeing people post about 2018 being included in it, so I wanted to confirm it for people here who didn't read the recall.

 

[Jerther]

Guilty as well... I posted the canadian recall details but I still thought 2018 was included for some reason.

2018 is an odd year for the LEAF...

New recall issued. I personally haven’t had issues with my battery, but I’ve been seeing others on this forum with battery health issues. Not sure if this will help or if this is another problem?

BATTERY SOC​

Effective Date: September 19th, 2024
NHTSA ID: TBD
NISSAN ID: R24B2

Summary
Affected vehicles may experience excessive lithium deposits within battery cells, increasing the electrical resistance and potentially causing a fluctuation in the state of charge. While an affected vehicle is Level 3 quick charging, the increased electrical resistance could result in rapid heating of the battery.

Risk
While an affected vehicle is Level 3 quick charging, the increased electrical resistance could result in rapid heating of the battery. If quick charging continues, a battery fire may occur increasing the risk of injury. Customers are instructed not to use Level 3 quick charging via the CHAdeMO connector until the remedy is completed
Remedy
Nissan is currently developing a remedy plan that is expected to be available November 2024.

Does anyone know if this is relevant to ZE1 Leafs from Dec17 onwards built in japan?
Or the UK built versions?
Thank you

Finally NHTSA/Safercar.gov has it. This only helps for US market Leafs since NHTSA is a US only body.

https://www.nhtsa.gov/vehicle/2020/NISSAN/LEAF/5%2520HB/FWD#recalls points to 2019 and 2020.
"September 19, 2024 NHTSA Campaign Number: 24V700000
Fire Risk from Quick Charging Battery

A quick charging battery that overheats increases the risk of a fire.

NHTSA Campaign Number: 24V700000
Manufacturer Nissan North America, Inc.

No not yet: it seems it either has no tip priority? If my 2019 Leaf Tekna has danger to catch fire while fast charging, than I would wanna know it today rather then tomorrow.

But then again with previous recalls they did the same, and dealerships don't take the potential danger seriously at all.

 

[barnesjohn00]

My guess is that'll be their solution, to throttle the QC making it slower than it already is...but we'll see.

I guess the question is if it's certain batches or a manufacturing process, and to what level is assembled in each location.

It looks like potentially at least some part of the battery is made in each respective plant, weather this is the cells themselves or just assembled into the finished packs. But there's a chance UK ones aren't affected.

this doesn't surprise me.
I recently did my first long distance trip since acquiring a ZE1 e+. Previously 99% of my charging was at home using a 15A and more recently 32A charger. A few test charges on various DC fast chargers just to ensure I knew how to use.

I use the 'car scanner' app and obd bluetooth dongle to monitor battery temp. (it similar to the more popular leafspy, car-scanner connects to a wide range of vehicles). When charging at fast chargers during my trip, I saw battery temp rise rapidly from 28-32 deg C to 40 deg C. The fast chargers I used were feeding at approx 50kw. I stopped fast DC charging after 15-25 minutes when battery temp reached 41 deg C.

I expect the Chademo communication protocol will have option for the car to tell the DC fast charger to reduce charge rates. If not exactly specified in the Chademo protocol, then via a protocol negotiated between the EV and charger. Reading various previous discussions on the CCS to Chademo adapters, it seems EV manufacturers and DC fast chargers have implemented the Chademo charging prototocol inconsistently, requiring some adaptation for the adapters as they deploy in the wild. (customers report collecting log files, sending back to the adapter manufacturers for debugging and software upgrades on the adapters)

I am disappointed. During my trip I had reason to call the EV charger operators for assistance, while they could start and stop charging sessions remotely, adjusting rate of charge was not remotely controllable nor controllable via app or locally on the machine. To my risk management mindset, this seems an obvious user requirement. Every EV can be expected to perform sub new specifications as the vehicle ages. Any public charging system should expect to encounter vehicles requiring reduced charge rates. Hopefully the market will improve on this part of the service.

I can see a sound argument to include 'occupation time' and 'rate of charge' in fees at fast chargers. (some already do) Maybe the market (in particular impatient EV drivers) is too immature to adopt this. IMHO a section of the market will resist being forced into the latest model and will want to use older, lower spec'd, underperforming EV's due to cost factors. any public charging policy which fails to include this user demographic will ostracise a large user base.

Here is the actual Nissan notice sent to affected owners. 24V-700

I feel this is related to the issue that I am experiencing. After the vehicle heats up the reported SOC fluctuates wildly. I've seen many reports of the same from other Leaf owners online. We took the car to our local Nissan dealer and they said they couldn't do anything because there was no error code. Out of the blue last week they called us and asked us to bring it in and they determined there was a "bad cell" and said that Nissan had agreed to replace it.
Guessing that there were enough reports of this issue and they were finally able to diagnose it. The recent fires were likely tangential.

I'm experiencing the same, but it started after the dealer performed a recall reprogramming the vcu.

 

[user546379]

For folks that are having rapid drop-offs on the battery percentage gauge, and are affected by this recall, what is your take on the fix being a software update? How does that fix lithium ion deposits in certain cells increasing electrical resistance? Anybody worried that Nissan is just going to reprogram the battery controller to reduce our capacity for the sake of having a more smooth drop off in the GOM?

Has there been any updates, news or speculation about this recall? My 2019 SL plus is affected, which states don't fast charge the car. I rarely fast charge, but do the occasional 200-300 mile road trip that requires it, for now I'll borrow or rent a car. My past QC charging experiences had the battery heating, not to red, but to an uncomfortable level after a single charge.

Nissan is under significant financial strain, and I wonder how and when they're going to deal with this.

You can always look under https://www.nhtsa.gov/vehicle/2019/NISSAN/LEAF%2520PLUS/5%2520HB/FWD#recalls under associated docs for 24V700000. I only see 4 associated docs right now

One of them is https://static.nhtsa.gov/odi/rcl/2024/RCMN-24V700-8664.pdf which says:
"Nissan is currently developing a remedy plan that includes software to prevent progression to thermal incidents. The remedy is expected to be available November 2024. Once the remedy is available, owners will receive an invitation to repair letter instructing them to bring their vehicle to an authorized Nissan dealer to have the remedy work completed at no cost to the owner."

November 2024 is repeated several times. At least for GM recalls, it seemed like the could be a lag of a few days between when we hear news vs. see a doc added.
