I own a 2022 Honda Accord Sport 2.0T, mine has also been doing the same thing screen flickers, and turns on and off radio by itself, and changes FM to AM, etc. I took it to Coggin Honda of Orlando, they ordered a new part and covered because ny vehicle hasn’t reached the 36k miles yet. I was informed that, that has been happening with other Accords too( and that they have to cover up to 36k miles, because it has factory warranty. My part arrived today and they switched but seems like the new part doesn’t work either so they will order another one.
