Warranty on a replacement 40kwh battery??

[Deleted member 41051]

Hi, all! Purchased a used 2016 Nissan Leaf yesterday. 105,000 miles on the car, original battery was replaced at 35,000 miles in September 2020 with a 40kwh battery. State of health looked good, so we purchased the car (without testing it on the highway) and immediately ran into a host of problems. Mv on LeafSpy shot up at highway speeds, turtle mode turned on, etc.

Called the Nissan dealer and turns out 2 owners ago (94,000 miles), they took it to a Nissan dealership and were recommended a battery replacement. They decided to decline and sell the car instead.

So this brings me to today – I'm wondering what the best next steps are. Unfortunately, I'm stuck with the car now, but was able to get some money back from the seller which softens the blow. I'm really hoping I could bring it into Nissan and get the battery replaced under warranty (within the 8 years and 100,000 miles of the replacement battery), but haven't seen much information out there about the warranty on a battery replacement.

Any advice on how to proceed? Mainly am wondering the best method to go about a warranty claim to increase the odds of this battery getting replaced. It's ridiculous that it's only 4 years old, has only 9 quick charges, and is having this terrible module/cell imbalancing.

Thanks so much, all!

Update: just booked a service appointment. Called into Consumer Affairs and they directed me to start a warranty claim at our local dealership. So far there haven't been any red flags saying this definitely won't be under warranty. Hoping for the best!

Good luck.
Not sure why previous owner declined free battery replacement at 94k miles. Warranty on replacement battery that was covered free under warranty is the remainder of the original warranty, so it would have been a free replacement again then. Did they sell it back to Nissan? That is the only reason other than convenience of replacing the car immediately selling at a loss.
My 2016 warranty expired at end of August, so replacement battery is also no longer covered.
For calendar, it depends when your 2016 model first went into service/sold new. You might be expired now or in a few months at most.
Hopefully you are lucky and they accept the 94k miles check as within 100k miles, else you are past the mileage limit now. If the previous owner sold it back to Nissan in lieu of replacement, then you may be out of luck and Nissan likely sold it used As Is with the degraded battery. Though with the behavior you describe, that is a lemon of a used car. Not sure the laws around that.
Was your purchase As Is? Or do you get any guarantee or extended warranty from the seller?
I would consider suing the seller for misrepresenting a non-functional car if they won't take it back for a full refund. If Nissan had bought it back and resold it, you'd have a hard time proving Nissan knew it had this particular issue at the time and not just a degraded battery performance.
Hope it works out for you.
