Strange problem with 2019 infotainment system

[HotChili]

For the last week or so when I turn the truck on I get the under dash (buzzer) chime instead of the chime through the infotainment audio. Turn the key off and back on, everything is normal. Sometimes the screen displays "System Off to save battery. Please turn ignition off or start engine." before I even put the key in. The truck is a 2019, completely stock XLT. Ideas?

You need a new battery.

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

Even if it's cranking normally now, it eventually won't. Battery is dying.

Yes this is the early indication of a battery going. If it's the original it is time.

I wonder why all the weird symptoms, can't it just prompt a "check battery" message? It would be a lot less hassle.

Aliens on Jupiter's moon, Europa.....sending subliminal message to you, via the info system, that your battery is going kuput....

That would be too easy, and show that someone at Ford programing, has a bit of common sense.
Unfortunately, common sense is not allowed at Ford, nor is any type of independent thought...

Probably because the battery is run at the jagged edge of dead by the BMS system so it would always say check battery.

I have a little $5 buck outdoor temp thermometer that has a battery level icon to tell me that the AAA battery is going bad....you'd think that someone at Ford could develop a "Battery Going Bad" icon for a $40,000 dollar (plus) vehicle !!!!

Well, that would add .025 per vehicle - can't have that!!!!!

There's more but these should be enough to get you started (no pun intended)

Agree completely! They should still shut things down to preserve battery power, but provide a message/prompt regarding battery replacement. God knows, they have a lot of other, less critical, messages flashing at us!

I had the same issue.

I had the same issue, With my 2019 XL. Replaced the battery. And have seen it pop up every once in a while. Last time was about 6 months ago.

So, I see all the posts of bad battery predictions on here but my 2019 is still going strong and I have repaired friends' batteries with this device too. I was really doubtful when I bought this but it has made a believer out of me.
