Restraints Lamp Indicator

[BroncoLA1]

2023 Black Diamond nonSAS with 6800 miles. While driving, the dash suddenly went black and rebooted (matter of seconds) with all the settings reset and then I had the Restraints Lamp Indicator warning, Tire Pressure Monitor System warning and the Antilock Brake System warning all come at once on my Ford app only. The dash does not display the warning symbols for these—it was solely through messages in my Ford app.

I restarted my car and drove it around for ~10 min and still no warning symbols on the dash. However, whenever I unbuckle my seatbelt while driving, the red seatbelt warning does not come on the dash nor does the car make beeping noises that the seatbelt is not buckled. But the dash does show when the seatbelt gets buckled. So it looks like the seatbelt sensor works but the seatbelt unbuckled warning doesn't? My tires also have plenty of air so it may be a sensor issue on the tire pressure warning?

Has anyone experienced something like this before? Is it just an electrical issue or perhaps these sensors failed to properly turn back on when the dash rebooted while I was driving? Hoping it’s not a big issue. The dealer says they're backed up so will take time to fix so hoping I can get some guidance here. Thanks in advance.

Try this:
General Reset for Wierdness
Unplug the negative battery terminal for about 5 minutes
Reconnect the negative terminal
This reboots all the modules and computers in the Bronco
Use a trickle charger rated for AGM batteries:
Connect (+) to the (+) battery terminal
Connect (-) to either chassis ground or the side tab on the (-) battery terminal
DO NOT connect directly to the (-) battery post
The BMS system must see the charger and going directly to the (-) battery post will bypass it.
Let the battery trickle charge over night. Low battery voltage, or just the BMS thinking there is low battery voltage, can cause a lot of odd things to occur and this corrects for that possibility.
