Capacity warranty is long over, and the 8yr/100k battery warranty covers only "defects". I asked if the battery has to fail completely before it would be covered, and she said it's possible that there could be a defect that is covered without a complete failure.
So, I think the best thing to do is have the dealer do a battery test, and I'll also price out the telematics upgrade (she said there's typically a copay fee of $199 or $299 to cover labor).
In the meantime, if anyone is interested in buying this car from me, let me know.
If your car has a 2G TCU, I personally would just disconnect it. Can be done with 15mins of your time or a free dealer visit. You can confirm it's done because you should have a leafspy DTC code showing the TCU comm error. Because it is a security related TSB, there is no charge for the disconnect.
If you have a 3G TCU upgrade already, you should be able to find a friendly dealer that will charge way less than $199 to upgrade the firmware to fix the battery drain issue. Many dealers do it for free--it takes like 5 minutes and honestly, it should be covered by Nissan anyway. If you must pay, I would push Nissan to fix that under their warranty--they sold a defective device and now want people to pay labor to fix the defect.
The only reason you should pay $199-299 is if you really want the EV connect app and you don't have the upgraded TCU. In that case, you're paying someone for the new TCU box and labor to install it. If you're considering selling the car, I wouldn't go this route...
The VLCI test will likely succeed. I can give you steps to determine if you have any out of balance cells, but again, you probably won't. I'm not aware of anyone having that test fail, even for a few people here with obvious cell failures. Having your battery fail outright would actually be the best scenario of all, but again, it's super unlikely. The 24kWh batteries are not known to randomly fail.
