2015 explorer shows low battery Features Temporarily Turned off

[widewave]

From yesterday, my 2015 explorer show low battery Features Temporarily Turned off when stop at stop sign.
Is that cause by battery? The battery is about 3.5 years old.
If I just start it and not drive it, No this warning!
I remembered that about two month ago, I use a huge brake on highway because the car ahead of mine stopped.
That's the only abnormal thing I can recall.
Thank you!

Update:
Now it show 'Low Battery Features Temporarily Turned off' after started and drove a while.
But I can still drive it a long way as no issue.

1/13 Update:
This car is 3.7L, another explorer is 3.5L.
I used the multimeter wrong way.
Now I measured the voltage: 12.6V, is that too low? another car battery is 12.4v.
I exchanged my two 2015 Explorer battery, this car is still show 'Low Battery Features Temporarily Turned off', another car is still good for now.
I use a obd scanner, but no code, no frame data.

1/14 update:
I exchanged my two 2015 Explorer battery and positive terminal, this car is still show 'Low Battery Features Temporarily Turned off', another car is still good for now.

1/15 update:
I measured battery voltage and alternator back terminal voltage when running.
This car 11.9V, the other car 14.9V.
Is the alternator bad or some fuse?

What is turning off? The battery can be tested for free at AutoZone

I don't know. Using heater. but not use radio or lights when driving.
The battery can still start the car without issue and I measure the voltage is about 24-26V.

The voltage should be 14.5v while running and around 12.5v when car is turned off.

You may have an electrical issue within the HVAC modules. You can check for bad modules with ForScan.

Either your battery is about to fail or it has a corroded connection.

You also need a new multimeter.

Welcome to the Forum.
From your Owner's Manual;

Looks like you either need a new battery or get the one you have charged up.

I measured my another 2015 ford explorer battery, 26V.
Do you mean OBD scan?

It do have corroded connection but I cleaned it, it still show low battery when stop...

Maybe because my car is PIU?

I sent you a private message a while ago about adding the trim so it appears in the margin. That is useful info to have.
There is a subforum for the PIU.

The connections are really corroded.
I clean them at my best but it may still not enough.

How to check fuse?
How could I drive it a long way if alternator was bad?
Thank you!

@widewave, please see my private message sent some time ago about adding the Required trim level (Base, XLT, Limited, etc.) of the Explorer.

Replace battery. It's probably on its last leg since you said it's 3.5 years old. Be sure to reset the battery monitoring system after replacing the battery.

Did you order an OEM Ford alternator? If not, you may still have issues as many members have had problems with aftermarket ones.

Recommend to not buy a non Motorcraft alternator

2014 Explorer limited here, battery was very low so i hooked up a volt meter to the battery while it was running. determined the alternator wasnt charging at all so i headed down to the parts store (auto zone). Came home with a duralast alternator and put it on the car. Started it up and the...

If you do, buy one from the dealer. There is people having issues with aftermarket ones. Do not get a rebuilt one either if all possible.
