This is happening with my 22 hybrid highlander!! However mine doesn’t stay on the glitch like that, mine will randomly completely shut down and then turn back on. Sometimes it won’t turn on and I need to hold down the power button to sort of soft reset it. I have taken it in 4 times now. Once for an update, then for replacement part (I forget what the part was called) and then for an update on that. The last time was supposed to be the last time, and they did a hard reset of the entire system, deleting my phone and everything, but less than 20 minutes on the road, with no Bluetooth device connected mind you, it glitched AGAIN. They have no answers for me, and it’s happening more often. It’s actually very unsafe bc I can’t rely on the navigation or Bluetooth for phone calls and I drive a lot, being a single working mother of three! Did you find any resolution and if so, what was it? I am ready to sell this car, after only a year of owning it bc it’s been happening since about 8 weeks after I purchased it, with only 5 miles! I’m so frustrated with Toyota - maybe it’s only the service department I have been going to, but I am hoping to find some answers here soon! Thank you!

Mine (2022 hybrid) started doing exactly what you describe a couple days ago. I have an appointment scheduled for this week, but after reading your post, I'm not confident that they will resolve the issue.

I wanted to provide an update. After replacing the touch screen, and the "radio", the issue has not been resolved. The dealership said they will have to contact another department within Toyota to try and find a fix. Very frustrating.
