Multiple faults suddenly pop out

I bought it as an used one at 43,000 miles.
Opened frunk to disconnect the fuse box for resetting the system, but it didn't help.
But yes, I saw that battery is original one.

Much past 38 months on the 12V battery is playing Russian Roulette. There are a lot of 2021s that are failing their 12V batteries now. Their mode of failure appears very similar to the symptoms you are illustrating. ??

no. that is not the 12v battery.

Disagree. The most common reason for multiple unrelated failures to be reported on the screen is poor network communicated by insufficient voltage due to a failing 12V battery. ??

While there might be multiple possibilities, eliminating the potential of a low voltage issue just makes logical sense.

So easy to do too.

Hello All! It was 2 to -4 degrees two nights ago in Columbus Ohio. Started my car the next morning and received a bunch of error messages like the ones mentioned. No awd, front camera assist, rear camera, driving modes, etc. somehow the car fully turned on and I drove to work. Went out at lunch to test it and the car wouldn’t turn on so I had to have it towed to the dealer. The dealer said it was a software issue and spent about three hours updating everything.
I have not found the multiple software issue/updates as the fix anywhere on here so. I wanted to post my experience. Hope this helps someone!
