I’ve had tons of 12V batteries fail too. Just in the past decade, almost every car has needed a new one within a few years. The worst was a Ram diesel that killed two sets of batteries in five years. So honestly, I wasn’t too surprised when my EV6’s battery needed a swap.
Seems like a weird design flaw to have a car with a massive battery that can’t run because a little one died. I get that 12V is needed for peripherals, but there’s got to be a better solution.
Just a reminder that this forum can be an echo chamber. The 12V might seem like a big issue here, but most people probably won’t have any problems.
With all the tech in cars today, you’d think they’d have some monitoring to warn us of a potential 12V failure! Kind of mind-blowing.
Anyone tried a LiFePO4 battery? It seems like a good fit for an EV with capacity monitoring.
I’ve owned over 10 cars, most of them new, and I’ve only had a battery issue once, with a 6-year-old one. Replacing it so often isn’t normal.

Maybe it’s just my luck, then. I currently have four ICE cars and have replaced six batteries across them since 2020. I finally bought a 12V charger and tester because I was tired of running to AutoZone every few months to check if they were still under warranty.
Jumper cables are basically standard equipment, though.
I think the ICCU issue is different from the standard 12V failure. But having a dead battery is like ordering from that one sketchy restaurant – most of the time it’s fine, but it will get you eventually.
Just my two cents.
