30k miles on my EV6 and I finally got the 12-volt battery warning, followed by the car not starting. I was able to jump it, and it’s been working fine since, but I know I’ll need to replace it soon.
The dealer told me the battery only has a 2-year warranty. Is that right? I’m seeing conflicting info online. It’s a 2022 model.
Is it worth pushing back on this with the dealer, or should I just buy a better battery myself and deal with the cost?
I wouldn’t bother with the dealership. They’ll just replace it with another mediocre Kia battery that might fail again soon.
Just get an AGM battery and be done with it. You can find one at Costco or Walmart for under $200—both made by Johnson Controls (or whatever they’re called now). I went even cheaper and bought one from Weize (it’s made in China).
Since I put in the AGM battery, I’ve had zero problems. The original Kia battery was only 6 months old, and even just walking near the car with the keys would make the mirrors unfold, causing the orange light to come on, meaning it was charging the 12v due to low voltage. Now I barely ever see that light anymore.

Wait, is that what the orange light means? I have a 2024 EV6 that I got in May, and I see that orange light on all night. I thought it was part of the security system… guess not!

That was my plan too until the dealer replaced the battery without even asking. After six days of my car sitting there, I got a text saying it was done. When I picked it up, they acted like they’d done me a huge favor. I just took the car and left.
Kia service is such a nightmare… I’ll avoid going back as much as I can.
Yep, it’s only a 2-year warranty. I bought my EV6 in January 2022, and my 12v battery failed after 26 months. I used a jump starter, and it worked fine for about a month before failing again. After the second time, I replaced the 12v battery myself. That was in June 2024, and I haven’t had any issues since.
