I have a 2019 RAV4 hybrid.
For the last 4 months or so, when I start the car, I don’t know what the AC will be set on: AC on? Fan on? Automatic? Temperature?
Today, the display behind the steering wheel is showing the Lane Assist indicator in the center of the little screen. I keep it on “mph”. Unexpected changes in this display have happened a few times over the 2 years I’ve owned the car.
The “easy” answer is, of course, that I inadvertently bumped some control button, which changed the setting without me being aware. Still…
The car seems to RANDOMLY change settings.
From an operational standpoint, it’s not a big deal. Resetting the AC to what I want, or getting the display to show mph is easy enough.
But, it does make me question the status of the electronics.

Might check with Toy and see if there are any “firmware” updates for your car. Also, see if there are any “notices”, or whatever Toy calls them, that tell of issues with your RAV4.

I agree with PoodleLover that you should check on a firmware update. I think it is also a good idea to get the dealer to log that a problem may exist now while your vehicle is still under warranty. That way if the computer fails at some later time you have a record showing the problem started while still in the warranty period. It could save you a lot of money in the future.

Hi PL and PF 
Thanks or the comments.
I’ve got a maintenance coming up (40K miles), and will ask about firmware updates.
Being that this is intermittent, I suspect that there will be no resolution.
again, thanks.

A new '23 RAV4 Hybrid Limited came to us this fall, only 1250 miles so far, but the buttonology is rather overwhelming…
We’ve read the mauals, watched various videos, but there is so much information, on top of daily living, a lot vanishes when you need it…
The other night, left SIL’s place to head home, it’s trying to connect via CarPlay to my iPhone… "Loading’… And then the windshield fogs up, inside! Where;s the defroster… Not easy for my old eyes to make out the icons in the dark, but eventually found a couple that cleared it up… Today, DW headed out to a print shop, never made it out of town before the windshield fogged up again… Over the phone, we got it going, but in the end she came home, and I drove her where we ended to go…
The other day, trying to open the rear hatch, it got confused, maybe because we both had our fobs or that it was unlocked or locked, but it was a bit irritating…
We want, need to lane assist, better mileage, so we will sort it out, but it’s a huge jump in tech from all our other vehicles…
OK, back the the manual…
