Loud and long beep/screech cabin

A loud beep or screech just happened out of nowhere while I was driving on the highway. It lasted at least 5 minutes. It only stopped because I pulled over and turned off the car. No CEL or messages. It was so loud that my ears are still muffled. Anyone experience this? I’ll upload the video

 

Video. You dont have to watch the whole thing. I just recorded it as much as I can for the dealership

could be speaker feedback? try turning off all peripheral devices (phones, mics, other BT devices etc) and sound to see if it makes a difference? throwing a random guess out there.

 

I heard it while I was listening to the radio and Bluetooth was off. Nothing connected to the car. I tried everything that I could do while driving. Honked the horn, turned my lights (inside/outside) off and on, turned radio off and on, rolled all windows up and down. When nothing worked, I began recording

 

Hybrid ?

 

Do you the camera by the rear view mirror?

 

Sounds like my inverter warning when battery is low on solar system. Is it a hybrid?

 

It isn’t a hybrid and I do have all cameras. It’s a platinum, NA, auto steps, with air suspension
