12VBattery Drain Error Message

[SFT-NY]

I have an 2023 Premium ER delivered on 12/31/22 (built mid-Nov 2022). Earlier this year I got an error message for 12V battery drain. Dealer had car for a week and could not replicate. Also said battery was being charged and holding charge.

On July 13, got a software update. On July 14, got 12V drain error message. On July 15, got another software update and the error message went away.
On July 31, the 12V drain error message reappeared. Stayed on until I got into dealer a week later. Again dealer could not replicate, dealer said battery was charging and battery was holding charge.

I have not change/added anything in the car and nothing is plugged in. Dealer referred to Ford as engineering case.

There was SSM about light switch issues. Dealer said they looked into that as well. That part was supposed to released mid Nov 2022 (which is when my car was built). Was there a revised switch released, since my car was built around the time the new one was Supposed to be released?

Has anyone had similar issues with the 12V battery drain errors appearing and found a solution.

There was SSM 50869 about light switch issues but have not heard that a new part has been released by Ford. Dealer said they looked into that as well. That part was supposed to released mid Nov 2022 (which is when my car was built)

Your dealer should look harder (though it may not apply if your car was built after August).

Check my topic for ideas what might be causing the battery drain:

Thread 'How to Recondition/Service Your 12V Battery'

They have the headlight switches in stock now, you can get one.

I had the battery drain warnings around February this year. No accessories were plugged in. After two or three times, I brought the vehicle in for service for this issue plus a problem with my APIM that was preventing Connected Navigation from receiving any data.

They corrected both issues by updating several modules and reprogramming the APIM.

Good luck!
