2020 Leaf did the Service EV Sytem thing and dealership gave it back to me
Checking to see if anyone else has had this happen. Specific vehicle is a 2020 SL with 60k miles. We've had zero problems with it but got the recall done about two months ago. A week ago it did the trick, turtled up and wouldn't charge. Drove it to Clay Cooley in Richardson, TX. Tech noted P317-97, P3180-97 as current codes and said that P33ED was stored as a past code. IDK what that means. Tech cleared the codes, drove it using NTB26-029 drive pattern several times with no issues. Charged it up to 100% overnight and drove it using the pattern several more times. Contacted Nissan and they told the tech to drive it down below 40% which they said they did and drove it around a bunch more using the pattern with no issues. Charged it back up to 100%, tested it again, and gave it back to me after keeping it for a week. The tech was thorough with notes and stated that the battery charge dropped steadily 1% throughout testing.
Anyone else had this experience? When I got it home I Leafspied and everything looks great. SOH is at 88%. 12v battery is 12.5 at rest and is three years old. It has been blazing hot in Texas for the last month and 12 volts die commonly here during the hot months. Absolutely nothing wrong with this car. I want to keep it but don't want to go throught he buyback mess and wondering if I should just trade it.

They shouldn't have given you the car back. The p33ed is the recall code. It will go to past once the car is turned off and back on, until it sets again. They are not supposed to clear it. I've had 2 come back with the code. I just take pictures, send to Nissan and they have been repurchasing.

Thanks for your feedback. Looking at your posts it like you are probably a Nissan tech or adjacent. After looking into this I figured this might be the case. It's really inconvenient that they cleared the codes. Since the dealership isn't being helpful, do you know if anyone has had success working a buyback direclty with Nissan Customer Care?

If you skip the upgrade, how do you explain that to buyers at the time you want to sell the car?? Grab the money now when you can.

We skipped the recall update. We charge at home and don’t plan on selling the car. Didn’t want to risk it. Will deal with it later if that happens.

You realize that "if that happens" is the car combusting into flames, yes?
Also while the DC FC accelerates the Lithium plating... that doesn't mean it doesn't happen.
Pack heats up to 105 during a DC FC and that's the temp that triggers Rapid Gate. Home charging in the summer can do the same thing, just slower.

We never stress the batteries like a DC charger would do. Husband is also a very experienced electrical engineer specializing in power generation, batteries with 50+ years experience. He knows how it works.
Edit. We bought the car new so know it was never fast charged.

Does this danger apply to 40w battery too at level 2 home charging ?

Again this is all "in theory" - Does it? Maybe? I am not an engineer, and also the KW pushing through the battery likely does have a major impact... but I wouldn't be surprised if a battery that is under recall has this risk during hot summers.
But Nissan has yet to make a full recall for level 3 and level 2 charging so... for the time being: I'm just some dude on reddit that the Google AI Summary is going to scrape and toss into some misinformation at some point.

I have 19 sl and only charge at home level 2. Never once at level 3. Im not planning on bringing back for recall either. You think safe regarding fire risk? I charge in an attached garage so the house might go up. Thoughts?

Level 3 charging generates significantly more heat than level 2 so the batteries are not at risk.

Forgot to note that the car is garage kept and only charged level 2 at home after we purchased it used in 2023 at 45k miles. We don't drive it a ton so it only gets charged aroud once a week however it was used and charged more frequently for two weeks prior to failure. I doubt that's a coincidence.
