low voltage warning

[Mach-Evo]

Has anyone had an alert for their 12v battery being low and a potential power drain? I have nothing installed on my car that is aftermarket. Used Carscanner to check and my battery is at 98 percent and 13.3 volts. I do have a weird rattle that has developed in the front center speaker too at around the same time

Yes, many have had that warning.

Yes! Got my '23 in Feb when I traded in my '21. Since I got it, I have periodically had a warning, 4-5 different times. In talking to dealership they told me to get rid of 3rd party apps, or accessories, which I have none. And eventually it stops, but this morning I go out to leave for work and unplug it from the charger and it won't start. I get a warning "stop safely" and the battery light and car w/exclamation point are red. It's in accessory mode but I can't put it in gear. So, it's stuck in my garage and I've reached out to dealership again and haven't heard back about what the heck I'm supposed to do with it.

Can you open the Frunk?


And then after reconnecting, put a good AGM charger on it and see if a full charge can get the car back to happy status?

I would just install a new battery.

Hi there! I can look into your Mach-E's speaker/error message concern on my end. To get started, could you please send a private message over with the name/location of your local Ford dealer and your Mach-E's VIN?

Not sure how to send you a private message. Been on this forum for 3 years, reading and learning but never posted before or sent private message.

I had it, just charge the 12 volt with a 15 amp minimum charger and it will straighten out after a few OTA updates. The 12v needs at the least 70% soc to get OTA updates. Don’t waste your money or time on a new battery. I still have the original battery in my lightning and it did the same thing, same with my 21 Mach e.

I had a similar issue - pulled the LVB cable and let it sit for 30 min; three weeks later it has not come back, but still no idea what the root cause might be.

I had such an event about 3 months ago on my at that time 9 month old 2023 MME. Local Dealer (who seems pretty good) kept the car for a few days and diagnosed a faulty BCM (body control module.) I suppose this allows the system to communicate with both the HVB and the 12V. They replaced that and at least so far, no problems.
