I have the same thing happening on my 2020 AT4. I brought it in to the dealership today and they recalibrated the sensors via an update and said it will take 4-6 hours of drive time to start working again. Strange thing is that when I was test driving it, I noticed a rapid flash when a car would go by.I didn’t think it was an issue. I bought the truck and left the dealership and shortly after I stopped to get food. When I restarted the truck the error came on “Side detection temporarily unavailable” it hasn’t worked since and still isn’t working after the recalibration. I’m not going to hold my breath but will update if it starts working.
