Back Doors Won't Open from Inside

[Timelessblur]

I have a question. This may be answered in somewhere in the manual but I'm here now so...

Child lock engaged. Car is for whatever reason completlely electricly dead. Can I get the back doors open?

My guess is nope. if the battery is completely dead and you turn on the safety lock before hand then it will not work and will be stuck in whatever state it was in before hand.

I believe it does the part electronically of disconnecting the level from the release much like how the manual buttons on other cars work.

I personally love the button and being able to turn on and off the child locks on the fly. Another plus is when my kid gets older and she can start opening the door when I get to my destinations I can turn them off so she can open the door and get out herself and then on the trip home load up and turn them back on for the drive home.

If the car is completely dead, the back doors won't open regardless of whether or not the child lock was set.

Yes. Pull the release handle a little and its electronic only pull it the rest of the way and that engages the mechanical release.

I believe that manual release only exists on the front doors.

I recall reading somewhere that in the event of a accident that all doors are unlocked. Can't remember where though. Can anybody confirm this?

The issue isn't that the doors are locked; it's that the mechanism to open the latch is electronic. The service manual shows mechanical releases on all doors, but I've seen reports that only the front doors made it to production.

Not certain, but that doesn't seem to pass NTSB approvals. Something gets lost with the Government. Nah, never happens. Just ask them.

I guess the only real well to tell would be to disconnect the 12V battery and try to open one of the back doors.

As I understand it, it happens when the airbags are triggered.

What happens? The doors fly open? That wouldn't be good either.

I can't count how many car crashes I was on that we had a hard time opening doors. Often the occupant is unable to unlock them. So, we break a back window to gain entry, then reach in and unlock. Can't do that with the MME. Hydraulic tools take considerable time to set up and get results. And distance from behind the "B" post to the front door handle is more than a first responder in turn-out gear could possibly reach. So, if it is not unlocked, the occupant is going to wear some glass. Not a ideal situation. Also immediate spinal stabilization is one of the first things done from the rear seat. As well as providing flying glass protection before front window access. All this of course is dependent on the first responder's initial assessment.

The back doors unlock with two pulls on the interior handle if the child lock is not on.

Has anyone else noticed the yellow light that goes on when the child lock is active?
I use the child lock to piss off the wife when she's riding in the back seat, no open windows and she's trapped! ?

Yes. Pull the release handle a little and its electronic only pull it the rest of the way and that engages the mechanical release.

To me, this is the superior solution. In a panic, it’s the same motion regardless of which device opens the door. In the Tesla, the different physical actions have led to issues during an emergency and are a problem especially for people unfamiliar with the car (in an Uber accident, for example).

With the Mach-E, you’re just pulling the same handle either way. Maybe you have to do it a little harder/farther, but in a panic, you’re yanking on that thing anyway.

My FE would allow for back doors to open by the exterior button with the 12V battery disconnected for some hours. Never tried it overnight. We had discussions back then about the possibility of a supercapacitor on one or more locks, never got resolved.

I guess somebody will need to leave the 12V battery disconnected for a while to really test it. Or try all the external buttons enough times to drain the supercapacitors and then try all the doors from the inside.

Not it

12V disconnected overnight, crawl in through an open window next day? I think I would want the frunk pull cord backup too, once I could not get the frunk bumper open to work with the 12V LVB disconnected. I guess the front door should open from the inside, no matter what? Then frunk is not an issue (to reconnect the 12V LVB). Damn, there is an Accord hybrid in my garage for now, keep forgetting Louiebluey is gone
