As is the case in other electric cars, the Mustang Mach-E keeps its 12-volt lead-acid battery topped up by essentially sipping power from the much larger lithium-ion battery pack. Based on owners’ accounts across multiple forum threads, including one who spoke to The Verge, the problem is this stops happening whenever the Mustang Mach-E is plugged in to charge up the larger battery pack.
That is especially an issue for owners in areas with cold weather, as Ford encourages them to leave their Mustang Mach-Es plugged in so the SUVs can use power from the grid to warm up before driving.FORD SAYS A “SMALL NUMBER” OF VEHICLES ARE AFFECTEDThe 12-volt battery powers many of the Mustang Mach-E’s systems (since the larger battery pack is high-voltage), and so when it dies, the electric SUV cannot be started...
It is possible to jump the 12-volt battery, just as you would jump-start an internal combustion car. But it’s not nearly as straightforward, especially because the battery is located behind the Mustang Mach-E’s front trunk, and the hood’s electronic latch is powered by the low-voltage battery.

Shouldn’t have been a surprise. Fairly common knowledge that battery performance declines in cold weather. I have a friend who loves his Tesla but one day this last winter he charged it up and took a long drive including a mountain pass. Battery charge levels start dropping rapidly and he found himself driving up the hill so slowly that the car actually started slipping backwards every couple of feet.
I am confused why an electric vehicle needs a 12 volt battery to start.
What???
nice
pair
of
shoes
More Indian H1B scumbag quality, I assume
She needs a better dye job and a different pair of shoes.
That is one UUUUUGGLLYYYYY sumbitch!
Now that pic at post #4...that is styling and profiling. Smooth baby.
Apparently it’s just there to make the design fail. /jk
All of the computer and lighting systems work off the 12 volt battery.
Why I don’t know. Probably more stable voltage
I’ve been told by a Ford tech there is a panel in the bumper that has connections to charge the 12 volt battery
No key or voltage needed
Does it affect the sound system that mimics a real car?
Oh, the travails of having an overgrown golf kart in the name of being politically correct..
But, but, they could come with RACING STRIPES!!
That made them uber-fast, no?
Did once. Out of North Little Rock heading to LRAFB, 102 mph in second gear.
Why is a brand new cars 12v battery losing it’s charge simply by being parked while the main lithium ion battery is being charged? What systems could be running cold or no cold that requires the 12v battery when the car is parked and OFF.
Probably pesky people who know about it are using parked Mach-E’s to charge their phones.
