Check out Costco as well. I found one there but already got the Walmart one, haven't had an issue yet.

This unfortunate issue just happened in my 2021 Niro EV. Luckily the doors were unlocked. I’m wondering what I can do if (when?) this happens again but the doors are locked? I’m guessing if he totally out of luck? Also, wondering if I need to recharge the 12v to full with my external charger, or just enough to start the car. Does someone know how the 12v is normally maintained. I guess I have been assuming it gets topped off regularly from the lithium battery.
 
If this has happened and your vehicle is fairly new, take it to your dealer and ask them. I think the 12V batteries they use are not very good but mine lasted 3 years.
 
You can open the door with the actual key. There is a silver button on the remote by the ring slot. Press that and you can pull out the physical key. There may be a picture in the manual, if that doesn't make sense.
I carry a small lithium jump pack, since it happened to me, once. I've not needed it, since then.
 
new here... I manufacture 12V lithium replacements. no issues with those wanting to spend less up front and stay with a lead battery,
about a 25 lb difference.. if that matters. Be aware, that EV 12v batteries deep cycle several times a day depending on amount of driving,
unlike a starter battery, which seems to be the type replacement being used. see lithiummoto dot com tesla page

What information do you have on your 12v lithium battery replacement?
 
Hi, The info is: the lithium battery will be to your dimensional specifications. And that seems to be 206L x 175W x 190H.
If you need it tweaked any dimension, let me know.
It will have a hold down footer front and back like OEM for clampdown.
SAE terminal posts.
choice of Ah, 30, 45, 60... the 60 may take a bigger case....
dual balancing circuitry included.
blue tooth monitoring optional
voltage state of charge LED optional.
lightweight of course
what else.....?
let me know
thanks

We just had our motor replaced in our 2019 Niro EV. Less than a week later I was sitting in the parking lot in accessories mode and got a message that said 12V battery warning. Please pull over safely or something along those lines. I turned off the car and scolded myself for not having it in utility mode. This morning we were going to go out to lunch as a family in the car said it didn’t recognize a key fob. Then after pushing the start button with the fob as indicated, we got a check regenerative brake system morning. Eventually everything died. We jumpstarted it and my husband is taking it to the dealership. Still under warranty so they should replace the battery for us. Did notice an earlier post where someone mentioned that the motor replacement may have caused the 12V battery to lose its integrity. Wondering if that happened to us or if it was just coincidence and we have reached the three-year mark where it seems these batteries like to die. We’re leaving Friday on a road trip so very grateful this didn’t happen in the middle of the Nevada desert.
 
3 yrs is all u can expect from a lead battery. If car is still in warranty, they may replace it free, but, 12V batteries are like tires.........

Considering it sat on their lot for 7 weeks waiting for a motor and they probably didn’t drive/charge it, they better cover it. Could be why the battery died.
 
They are claiming it was a “history code,” due to the car sitting around for so long. Saying the battery is 100% and the code just needs to be cleared. They’re going to test it again after sitting around for a few more hours.
 
Well, that was a goose-chase. Costco didn't have a compatible battery. Nor did my local Lordco. Ended up going to a local battery shop (Edmonds) and they had a P11-4 size battery that fit and worked in my Niro. Specs were slightly better than the OEM battery.

Cost was $125 CAD.
