I took my EV6 GT-Line into the dealership in June for the ICCU recall update, and everything seemed fine until today. My car wouldn’t start after a quick stop at a restaurant about 25 minutes from home. Roadside assistance came by and jumpstarted it, and I was able to drive home without any issues.
I’ve scheduled an appointment with my dealership to replace the battery, but they mentioned their EV technician is no longer there, so they can’t verify if the software update was installed correctly.
My question is, will replacing the 12V battery solve this issue going forward? Should I also book another appointment at a different dealership to check if the software update was properly installed? Any advice would be appreciated, thanks!
You definitely need a new battery. I’d recommend getting an AGM one. Not sure if it’s worth going through the dealership, but since it’s a lease, they might cover it.

Yep, dealership is covering the battery since it’s a lease, so no cost to me.

Glad to hear it’s covered! I’ll be rooting for you.
In my experience, getting a replacement 12V can be tricky even if you have evidence it’s going bad. The dealership has to run a load test and send the results to corporate for a warranty replacement. It involves connecting the battery to a charger for a few hours and then running a digital load test. If you have a good service advisor, they might run the test a few times until it fails so they can replace it.
After going through this process a couple of times and wasting hours on dealership visits, I ended up just replacing mine with an AGM H5 battery. AGM batteries are great for EVs since they handle deeper discharges better, and the physical design prevents long-term damage like sulphate buildup on the plates.
Edit: I know it’s a lease, but sometimes the peace of mind from an AGM battery is worth it.

Thanks for the insight! Hopefully, it goes smoothly tomorrow, but if not, I might consider replacing it myself.
