it says absolutely nothing about cold weather. the thing that stirred me up is that it goes into the mode even though it started...

The performance of all batteries drops drastically at low temperatures; however, the elevated internal resistance will cause some warming effect because of efficiency loss during use. At –20°C (–4°F) most batteries are at about 50 percent performance level.

I don't imagine most people are surprised that cranking your engine over in low temps causes the battery to struggle.

This would, obviously, trigger a low battery warning sensor.

Was -42 here overnight, -25 now (at 1:55pm) and just started mine with FordPass. Nothing about deep sleep mode, but interestingly enough for the first time I get a "Warning: Vehicle failed to start" on the app. Yet I look outside and it is running. Refreshing the app brings the vehicle controls backup and not showing the vehicle running, time left etc., even though I see it plainly running.

Methinks they have some bugs to iron out with this app..

Ha us too.....my wife's Edge hasn't run in two days lol but that thing has always had a bit of a weak battery.

As an EET graduate, I understand this. However, those that don't, are those that programmed this. Take for example... your vehicle's computer usually won't store a code unless the condition has been met for a predetermined amount of times/cycles/duration. So why wasn't that kind of thought put into the programming for the "Deep Sleep Mode" condition setting parameters? It seems to trigger it the second it senses a voltage drop below their predetermined threshold, instead of waiting to see for a predetermined amount of time to eliminate what should be false triggers (such as this).

I see the message you get now on the Ford Pass app is more detailed than it was when it first happened to me.

Twice in the last two days it came back with a message that the vehicle did not start, when in fact, it did. I'll attribute it to the extreme cold, but will see what happens as it's warming up after today.

Sounds like there are programming bugs on the vehicle end that need to be ironed out, rather than telling us that this is "normal behavior".

My 2018 has thrown 2 codes in the last 2 weeks, CEL just came on again. Perhaps it's related, perhaps not..
