Mach e dead in garage, next step

[B177y]

I don't think that's the 12v battery, I think that's the high voltage battery percentage. The reason I'm saying that is because my whole car died just as I pulled into my carport and started to put it into park. Dead as a door nail, luckily I was able to get all of my stuff out of the car and pop the trunk using the manual pull. I just looked online and my battery percentage is 78% just like it was on the high voltage battery at the time of the failure. Same percent as it shows in the app.

It was changed a few months ago to show the HV battery. It did used to erroneously show the LV battery percentage. Ford finally caught up with their error.

Would make sense for them to show both, one could argue that knowing the LV battery percentage is more important information as it can die without warning.

I, and I'm sure many others, agree. It was a very useful error while it lasted.

I've currently got mine on a trickle charger, anyone think that will work?

If not, will I need to get a jumpstart to make it to the dealership for a new battery?

Or am I looking at having to get one and replace it myself?

Thanks in advance

I did not have the dead battery happen to me while I had my MME, but from what others have described in other posts about this problem, replacement is probably the best recommendation. If your MME is a '21 or early '22, the batteries just die. 3 years +/- seems to be the magic time for failure.

A trickle charger may get you going for a bit, but if the battery is internally toast, it will die again rather quickly. If you have a newer MME still under warranty, the LV battery should be covered. Even if you can get started after being on a trickle charger, I wouldn't trust it at all. If you died while pulling in to your garage, it's a pretty good sign that the battery is done since it charges from the HV battery while the car is on. It's similar to when a battery dies in an ICE car, the car will drive until you shut it off because the alternator keeps you going, but you can't start the car after shutting it off and the battery won't hold a charge no matter how long you keep it on a charger.

Thanks, guess I'll be calling the dealership on Monday and see if they have one in stock and the mobile service crew can come out and install a new one. Thanks for your help @B177y

I had a similar experience on June 8 but much more serious. My wife was at Walmart with our two kids and as she got out the car closing her door to head to the back door to get our kids the car somehow died. As you noted, nothing worked to unlock the door. Mind you we live in NC, and the outside temperature was about 95 degrees. I tried to use the ford pass to remotely unlock the doors, roll down the windows, remote start the car but nothing worked. At this time, panic and terror started to set in as my wife starts to see our 1- and 3-year-old screaming in terror. We had no choice but to call the fire department. Ultimately, the fire department had to break the front passenger window to get our kids out. We were told that the inside temp of the car was around 120 degrees, and our kids would have been dead in about 3 more minutes.

At this time, I still have not been told what caused this issue and my car has been in the shop for a month now. I also had the 12v replaced on 4-20 so it basically was brand new. I have a 2022 GTPE that has been in the shop 5 times since Aug 2023 for HVJB/Battery issues. The HVJB has been replaced 3 times already. I tried to request a buyback after my 3rd HVJB was replaced back in May but was denied and I tried again after this car almost killed my kids and was denied again so good luck.

What a wild experience it must have been for you, and great to read you got your children out safely.

You should get this in the media news that such situations can and apparently do occur daily for many owners of a Mach-e.
Ford should / must be forced by the authorities to install a security solution so that such situations will not or cannot occur.

Security is simply not thought into this solution, where we cannot open doors / or the back compartment manually with the associated key, or other access options.

Good thing you weren't on holiday in the woods, where no one else is in the area....There is many situations where it could go completely wrong with this solution Ford has chosen.

A solution could perhaps be that a pull cable was made which is led down to the front access cover where the 2 wires are located which must have 12v to open the front flap.
There would then have to be a Jump starter in the front compartment, to connect the 12v battery afterwards.

Just hope that Ford takes this seriously and finds a sensible solution to the challenge and gets it rolled out as soon as possible
