- 2021 Mustang Mach-E AWD ER
Glad the baby is ok, but I fully sympathize. Worst, I think the issue may not be with the battery(12V or otherwise) as much as software/sensors.here in Quebec we have been experiencing a wave of polar cold for a few days. We reached temperatures of less than 30 Celsius. Several Mustang Mach-E owners have had issues with the 12v battery. One of the people who had this problem was put in a situation that would have serious consequences as she described in her post on the FB site « propriétaires Mustang Mach-E Quebec ».
''A really worrying situation happened to me with my MME premium AWD this morning: I had 115km of autonomy and after a few stops during my shopping my car did not start and I heard a noise in the speakers . I called roadside assistance and there was a 1:30-2:30 wait so someone came to pick me up because I was with my 10 month old baby in the car. After 20 minutes when I got out of the car the door closed behind me and the doors wouldn't open anymore and my baby was stuck in the car for another 30 minutes while the police and the the tug arrives. The tug wasn't able to open the door as it's all electric and there is no emergency way to open the doors if the battery is dead...had to have my dealer move on place and he opens the hood with an intrumejt and dismantles plastic parts to access the battery so that the doors open and I can get my baby out. Words fail me to tell you how my mom's heart suffered during this episode and that I really don't want it to happen again…. After reflection I want to know if this happened to another of you? And here are my solutions and I especially want to hear yours. My car is at the dealership for diagnostics. I would like to be able to have confidence in my vehicle and I will need them to be very convincing for me to agree to take it back…
- change of battery for a more powerful one?
- added smart charger?
- display the level of the 12 volt battery and an alert if it drops below a critical threshold
- Make a reminder for doors that do not have an emergency opening system
Thanks for helping me think through all this….’’
I hope Ford will fix this problem once and for all….
Ps Sorry for m’y english
I have a 2-week old Mach-E in Montreal and last night and today. AFter removing car from charger in the driveway fully charged:
Sitting in driveway i pressed the accessory start button in the driveway. I did this to start the climate controls to warm cabin - but while accessory mode said it was on neither heat, nor steering heat or seat heat would activate. the car has also shown me the dreaded "Pull over now" and low battery icons! I did not believe it since the car was freshly off charger.
At that point I powered off and pressed brake pedal and start together. Same error state. I powered off.
I opened the door, closed the door, and pressed brake and start button again. Normal state, batteries, heat and operations restored. This has happened this way two times now at -20C.
My takeaway is the car is reacting to reading differences in an unpredicted way somewhere in the software. And i think there are other situations in cold weather that are doing the same way, and may have impacted the original post writer's experience.
For what it is worth. Other insights are appreciated.
