Dead this morning

General

Got a 2024 EV6 GTL AWD with about 1400 miles on it, and it was completely dead this morning. Couldn’t even unlock the doors. The EV battery was at around 60% last night.

Could this be the 12v battery? I thought they fixed that with the ICCU for the 2024 models. Roadside service is on the way, and they’ll probably just jump it. If it starts up, should I push for them to take it to the dealer anyway?

Just grab yourself a jumper pack, no need for roadside assistance.

Will the 12v battery charge fully once the car is running? And if I take it to the dealer, will they actually ‘fix’ anything or just jump it and send me home?

If the ICCU is working fine, then yes, it’ll charge the 12v. If the ICCU is the issue, you’ll need the jumper pack to keep it alive long enough to drive it to the dealer.

Only the dealer can diagnose ICCU issues, right? It’s weird—jumped it, started easily, and no warnings about the 12v battery.

Do you keep your jumper in the car? How often do you charge it?

I store mine in the frunk and have a reminder to recharge it every six months (or after using it).

I keep mine plugged into the USB-C port, so it’s always charged. Haven’t needed it for the EV6 yet, though.

Can anyone share a link for one of these jumper packs? Thanks in advance!

This brand is a bit pricier but is known for being safe (no sparks, can’t connect it backward, etc.). Mechanics and roadside services use it. https://www.amazon.com/dp/B015TKPT1A

I have this model. Works great, and it’s on sale right now for $109 for Prime members, which is a good deal.

Wtf, a brand new car’s 12v battery shouldn’t be dying like that.

Depends on how you use it. If you leave it on in accessory mode, it’ll drain the 12v just like in a gas car.

@Imani
There shouldn’t even be an accessory mode. It’s either on or in utility mode. Accessory mode just kills the 12v battery.

You need accessory mode to power the car without engaging the high-power systems.

@Imani
But when is accessory mode really useful?

Mine did the same thing 8 months ago. They said it got stuck in an update. It happened again this week. The first time, my car was in the shop for 22 days. This time, they still have it. They’ll tell you to get a battery and jump it, but that’s not a long-term solution. I’m starting the buyback process and calling it a lemon. Love the car, but I don’t feel safe anymore.

That’s why I leased mine. I heard they fixed it for the 2025 refresh, so I’m waiting to see before committing to buying.
