Early 12V Battery Failure in Ariya

[bbybee49]

Has anyone had to swap out the 12V battery in their Ariya super early, like within a year or so?
Just curious if this is a common thing or if there’s something else messing with the battery’s life.

My 2023 Premier's 12V battery crapped out after just a year! Can you believe it? Had to get it towed to the dealer, what a total pain!
Turns out, I'm not the only one with this issue….seems like a common problem, tsk tsk.

Mine was at 4 months. My ARIYA Premiere was an early one, bought 1/2023.

I’ve heard of a few Ariya owners dealing with early 12V battery replacements. EVs rely on the 12V battery for a lot of their systems, and if it’s not getting enough charge from the main battery, it can wear out faster. It could be an issue with the charging system not keeping the 12V topped up properly. If your car has been parked for long stretches, that might contribute to it too. One thing that’s helped some owners is using a trickle charger occasionally, especially if the car isn’t driven regularly.

This might not be specific to the Ariya. It seems like 12v batteries just aren’t as durable as they used to be, or maybe today’s cars drain them faster. Our other car needed a new 12v battery within two years.

Mine only lasted a year before it broke. Not sure if it's the battery or if most EVs have similar issues.

I had my 12V battery die way too early, and Nissan actually replaced it under warranty, so if you haven’t checked yet, it’s worth asking. Apparently, some of these early batteries aren’t holding charge well, especially in extreme hot or cold climates. Also, if your car is frequently showing the “12V battery low” warning on the dash, it might not just be the battery but a charging system issue. A cheap 12V battery monitor can help track voltage drops before it fully dies.
