My Mach-E's been flashing 12V battery warnings lately, so I took a look under the hood and, to my dismay, the voltage is hanging on by a thread at just 12.15V. That’s definitely not a healthy sign, is it? The car’s only two years old and hasn’t had any major battery drama or power hiccups, so it’s kinda odd that the 12V battery might be crapping out already. I’m really crossing my fingers this gets covered under warranty! Anyone else run into this problem? Feels way too soon for this kind of hassle!
 
Did you try checking the voltage reading using the OBD? The car's HV battery should charge the 12V battery even when the vehicle is parked. If this is not happening, it could be a problem with the 12V battery, considering the DC-to-DC converter is functioning properly.

Yep, 12.15V is definitely on the low side for the 12V battery. With EVs, the 12V can sometimes drain faster because it’s constantly running smaller systems even when the car’s “off.” It sounds like warranty should cover this since it’s still early. Keep an eye on it, and if you notice the voltage dropping lower, definitely push for a replacement! Then check it again when you get a replacement! 🤔
