Used 2016 SL Battery Check and Warranty Help

Hello,

I just bought a 2016 SL from Carvana today. It has 44k miles, 10 bars, and Leafspy shows the SoH is 68.21%. This is much lower capacity than I expected so I'm leaning towards returning it.

However, if this car qualifies for the battery warranty free replacement, I would keep it.

From what I've researched, they will provide a free replacement if it gets to 9 bars under 100k miles or 8 years.

Could anyone please offer any guidance on how to estimate when the 3rd bar will go away and if the car will qualify for the battery warranty?

Nissan will insist that the BMS "update" be applied to the car. I expect one bar to return after that - for a while, anyway. If you need near full range, don't try to play "battery warranty roulette."

At an SOH of 68%, you should have lost the third bar already. The fourth bar should drop at around 64%. It really depends on how much you paid for it and rather the range is currently sufficient for your needs or not. If the range is marginal, I'd return it.

IMO, a 2016 with a 68% SOH has had an abused life... If you have bought it from Carvana, then you probably paid market value for it... Which would be $12-14,000 for it?

For that kind of money, you can buy any car.... In great condition. Why accept to have a damaged car, and have to do the leg work and inconvenience of seeking a solution to the problem car???

You may be able to get a new battery, but at what cost? And maybe not? Use the carvana warranty against them in this case... Unless you like playing a gamble.

PS - Are you sure you read the SOH as 68%? Or was it the SOC, which is the level of charge?

Your reading is correct and unless you live a cold weather climate, eventually triggering the warranty seems like a given unless the software update works, in which case you are good to go.

So the only question is whether you can tolerate the range as it approaches warranty.

Unless they changed it, the warranty trigger is 8 bars, not 9.

Good catch. Agreed

Based on the replies, it seems like it's risky to play the warranty game.

I woke up this morning to it charged 97% with the GoM reading 97 miles. SoH is still 68%. Drove 7ish miles to work mixed freeway and local streets with it reading 91 miles. While, it easily meets my daily commute needs, I'd rather trade it in for one with a better SoH.

Thank you all for the replies!

Depends on your climate. if seasonal with some warm summer months you’ll get a new battery. The battery degradation warranty is 8 yrs 100000 miles

Something does not make sense here.. If he charged to 97% (GOM - 97 miles), then drove 7 miles and the GOM still shows 91 miles of range, then this battery is still very strong.

If the GOM is showing a full battery 100% with 100 miles of range, the battery CANNOT be at a SOH of only 68%. With that low state of health, the GOM would be showing... Like 50-60 miles of range?? At a full charge??

My car's SOH is 92%, and when I full charge, my GOM is still showing 100 miles of range, like it has for years.
