And the rear doors might require a second pull for the door to open - not a big deal if people are already panic-pulling on the lever trying to get out, I think.
I do not think there is any emergency release mechanism on anything but the driver's door. When my door control module failed, my rear passenger door was completely stuck. It would not open from the inside or out. The dealership told me they had to break the door panel to release the latch before they could even open the door. A few more details here: https://www.macheforum.com/site/threads/rear-door-button-issue.31485/#post-736733

Or even better would be automakers getting over their obsession with constantly adding unnecessary tech to replace perfectly functioning mechanical systems. Morons, the lot of them.
I like it, as long as there is a manual component to overcome a system failure — which there is.

Not for the rear doors, apparently. Also, there is no mechanical release on the outside, either. Overall, the push-button, electronic release, etc. is a step backwards in design.

" Yeah, if only one could climb up into the front seats of the vehicle to escape. If only... " If you weren't being sarcastic then disregard. But not everyone can climb over the front seats in an emergency.
You referenced 'infants in car seats'. They aren't climbing/opening/escaping anything by themselves, so I'm not sure what the point of your post was in regards to mine.

This is way too difficult. You posted a snarky comment about a line in the article, "... but occupants may also end up stuck in the back seat." You said, "Yeah, if only one could climb up into the front seats of the vehicle to escape. If only..." I was making a snarky, rhetorical comment that not every one can climb over the front seats (e.g. babies in car seats) as you seem to have indicated. If you don't understand that, let it go. We've wasted too much time on this already. :confused:

I get that, but that is easy to work. Yes, it’s an oversight, and it’s areas like this where we need safety regulations in place to prevent 100% reliance on systems that can fail just because of a dead battery. That being said, I still like them. Sounds like an easy fix, if the safety boards step up and mandate the rear doors be able to mechanically opened.

Yes, a door control module failure is similar to a door latch failure - you're stuck. But that doesn't mean there isn't an emergency release mechanism - it just means that that emergency release mechanism doesn't work in all situations. @JonesyDoe's post confirms that the door unlock/open mechanisms work when the 12V battery is disconnected.

I will say that I had de-energized the vehicle for about 2 hours and was still able to open all 4 doors from the outside, but never tried the liftgate. I wonder if it's a capacitor or if they have a coin-battery? I know that BMW used to have a CR2032 in the E-Call module so that it worked when the vehicle died. Time to do some digging ?

So I can't really find an answer... The only thing I can think is that the Restraint Control Module communicates with each of the Door Latch Control Modules. In the RCM they utilize something called the Extended Power Module. The EPM is meant to keep power to the airbag system when the ignition is off but the vehicle is traveling more than 4mph. It looks like this is actually on a couple of Fords, such as the Maverick, but I don't know if it communicates with the door latch. I mean, if it powers the RCM and the RCM communicates with the door latch, then... I guess?
