Software Update - 12v SoC

[Greylake]

Hi folks, I'm wondering if there is someone in the group who could look up my VIN and see what my SoC was when I attempted to update this morning (07/14/25)? 3FMTK4SX3MME02439

I read the sticky and watched some videos about the software updates so what I did was:
1. I long-charged overnight, from 12am-4am. At 4:30am I attempted to update, but it failed saying "battery too low".
2. So then, I let my car run for just over 2 hours in the garage (idling, lights off, etc). But tried again, and same message

I went ahead and ordered an OBD2 dongle so I can use CarScanner in the future.

Thank you in advance!

I think there's a thread for that in this sub, but in the past I've been helped by @Mach-Lee

Good luck. I now use an OBD and Car Scanner to do it.

Thank you! Yes I got an OBD2 dongle coming in the mail, I'll see if I can find that sub also

The reason the OTA is failing is due to BMS data quality. Check out this post and look for the section that talks about BMS data quality:

Having the exact same issue. SOC of 12V is over 75% but get same message regarding the update. However, my battery is 3 1/2 years old. Having it checked at dealer. Live in Vt, don’t want to go into next winter with current battery.

Ah let me know how that goes! I'm on the original battery too

3 1/2 years on 2021 battery. Have almost 30,000 miles, think I will wait till when the recall is ready to be installed at dealer and get it all done at the same time.

75% sometimes isn’t enough especially if your battery is aged, get it above 85% and try again.
