Owner of a 2022 Mach-E Premium here. I have had zero issues with the car and I absolutely love owning and driving it. I have a question about future servicing and am seeking input:

Reading other posts and watching YouTube videos about eventual 12v battery replacement, I was wondering if for those who had to replace theirs if there was a warning indicator other than just waking up to a dead battery one day. This would normally not be a worry for me as battery replacement is straight forward with easy access on my older F-150. But with the Mach-E the battery is behind the frunk and is pretty much buried behind secure plastic panels. I know it is doable but would like to know in advance when it is time so I am not struggling trying to get a jump start with those frunk panels and the hidden battery while out on the road. What started this thought was seeing this photo posted by a Tesla owner. Thanks in advance!

Yes in theory, but don't count on them:

Remember that batteries can just die with no warning. And preventive replacement is recommended, i.e. after 3-5 years depending on your climate.

From what I have read, unless you have something additional to the car that is monitoring the LVB, you just one day get a dead battery. If you have an OBD-2 dongle you can monitor, and there are volt meters that can be plugged into the cigarette lighter socket so you can monitor. ??

That is exactly what happened to me...in the middle of nowhere on a mountain pass with no cell service. Ford roadside was less than helpful to put it politely. My 12V just died and bricked the car.
