You can go here and see if there are any updates for your VIN.

I checked the website, there is no update for 2023. I called the dealer, they said that since the problem is resolved diagnosis will not find anything. Rather they would charge 80-200$ even though i am under warranty.

Suggest me what I should do....

 

There shouldn't be a connection between the function of the traction control system and the multimedia screen, so that in itself is odd unless it's a coincidence somehow.

The only thing that you can update firmware on is the multimedia system, and Toyota doesn't issue updates for that very often. Toyota separates all of its computerized functions in different physical modules. The dealer has to update anything other than the multimedia system, again assuming that Toyota issued some kind of update for that particular module.

 

Thanks for this information. I just updated my multimedia firmware via USB, even though when I ran the OTA firmware update it says it's up to date, then when I put the USB in it says there is an update.

 

Entune 3.0 (prior to model year 2023) over-the-air updates only update the "Apps" on the system (which isn't much).
You must do the USB update to truly upgrade the firmware and get bug fixes for the system.

Not sure if Toyota Audio Multimedia (TAM) on the 2023's will have full OTA updates or not.

 

I had similar issues yesterday because of ice build up on front/grill camera. Apparently unable to properly assess environment.

 

That update fixed two pet peeves I had with the entertainment unit. First in CarPlay Google Maps navigation mode it wouldn’t show what Sirius CM station I was tuned to, that now works.
Then if I am parked and using my phone while plugged into CarPlay and there was some type of video in a tweet or Facebook post it would switch the audio source to the iPhone. It still does that, but now when I navigate away from the video file the entertainment unit puts audio source back to Sirius.

 

hey i also have the 2023 xse i was wondering if we could connect and share somethings about our cars i am in vancouver and it rains alot and when i park i get rain water under my hood on the plastic bottom cover i was wondering if this is normal it has been stressing me for sometime and that if your does something similer u notice , also in my car the wind noise is loud sometimes and it comes alot of it from the rear wheel wells
