Updated to 2018.18.3 now have 12v battery problem

[rcsting]

I just updated to 2018.18.3 today and immediately after the update I received the “ 12v battery needs service” message on screen.

I called the Service Center and they checked my Model 3 remotely and said if the error doesn’t go away I will need a battery in a few weeks which will be replaced by a Ranger. I’m concerned that I might get stranded.

Wondering if anyone else has has this error message.

Thanks

Yes. Many people that have dashcams have seen that. Do you have anything connected to any of the charging/USB ports?

@rcsting,

Agreed....that was my first thought/question as well. Do you have a dashcam hardwired or connected to the 12v battery? Some who wired cams this way have trashed their 12v battery needing a replacement. Barring that if not maybe just a bug with the update? Please let us know what tesla says. Have them check your car remotely.
