Where do I start?

[brtobler]

I started our 2019 max limited yesterday morning and the climate control had no juice (the screen above still works). Before checking fuses I tried unplugging the battery and reattaching after 15 minutes. After doing that, we got a blind sensor fault, cross traffic sensor fault, tire pressure fault, and airbag light on the dash. On top of that, the passenger window doesn’t roll down, the key fob doesn’t work to lock/unlock (it still unlocks when you touch the handle), and the knobs for the media have no juice. So ya, where do I start? (I’ve attached pictures)

Possibly bad battery? I would start by measuring the battery voltage with a multimeter with the key on.

With a "weak" 12v battery, the Auto Engine Shut-Off "Feature" is disabled... in your picture the "A" with the slash through it, just above your odometer is the disabled feature logo.

I had to replace my 2019's 12v battery a year ago... and then I learned that I did not like the engine stopping and restarting so much that I bought the "disabling jumper and installed it to keep the engine running... ( I got my replacement battery at Costco... most bang for the buck.)

hopefully, you find the root cause. I second the check your 12V battery voltage as @wakeboarder suggests!

I also would have battery checked.

You asked for advice and should have at least acknowledged the helpful information that was posted - and perhaps let the forum know what you resolved.
