Strange problem with 2019 infotainment system

[HotChili]

Well, y'all were close (or so it seems). As I was leaving work I did a push/pull on all the cables at the battery and the problem disappeared. I'm going to do a thorough cleaning of the terminals and see what happens. I do agree, though, that at 5 years old the battery is probably coming to the end of its life.

(edit) There's no obvious corrosion but, from experience, I know that means nothing.

Truck cranks normally, no indication of a battery issue (other than above)

The truck not only tracks the batt state of charge , but also the rate of discharge .

The Battery Management System is controlling that, but there are other issues that could cause it besides a bad battery. Short jaunts without sufficient recharge time is one of them. BMS should also shut off the stop/start at this point. Read the manual.

Yeah, your battery is on it's last legs. There is one thing you could try witch might help and that is to reset your BMS chip. It's the little square item on the negative post of your battery. Do the following:
- Turn the truck on, do not start.
- Flash your headlights six times
- Flash your brake lights three times
- Wait for the battery symbol on the dash to blink (about 10-15 seconds).
If it doesn't work the first time try, try again.
In truth, this isn't likely to help, but it's worth a try and MAY give you a few more months, but your battery is just hanging on. If you desire to make it last as long as humanly possible, this would be a good time to purchase a starter pack and put it under the back seat. You don't want to be in the middle of no where and hear only clicking when you attempt to start your truck without a backup.

FYI. I was getting these same messages on my 2019. What I found is that my negative terminal was very loose. Not for sure why but I pulled it off and cleaned it and reinstalled the cable. I then tightened the terminal and the warning message did not reappear. No new battery was needed.

You forgot to mention that after all that, you have to exit the truck via the passenger window, hop around the truck, backward, on your left foot, counter-clockwise, while spelling "jambalaya", backwards, 3 times.
If no positive response, repeat....

If Ford simply put a "bad battery" message on the screen , most people would simply go buy a battery at Wherever auto parts , but if all the crazy stuff comes up on the screen , your gonna take it in to the dealer most likely, sneaky , but kinda smart too ...

@Grumpaw. You forgot standing on one foot, counter clockwise rotating three times on an odd numbered day, but even numbered month ... and on Leap Year, which is fortunatley here.

Then the message would say, "contact your Ford dealer for battery replacement".

Once you know it's the battery ,no need to bring the dealer in on it , but crazy non relevant messages will strike fear in the uninformed...

Is your truck stock?

If so, has your auto stop/start been acting up or not working at all?

This was my first sign that my battery was failing.

if you don’t want to get stuck somewhere get a new battery. It’s 5 years old…

So if a new battery is required. You need to go to the dealer to reset the computer and scan the battery ?
