Someone or something controlling my controller input somehow

I am aware people are going to think i am crazy or lying, but i play forza horizon 3 and 4 and motorsport 7. Well, i became pretty good at horizon 3. After becoming rather well at it i started having trouble with my controller input. It was doing things
i was not making it do. For example. If i go into a turn easily it will go hard or not at all. Also it turns left and right over and over to make me lose control. I know what most of you are going to say. Buy a new controller. Well, i did. I use to have a
logitech g29 when i played on a pc. Sold pc and wheel because i could not get these problems to stop. After several months i began to miss playing. So i bought an xbox one s. Only for the first 30-45 min i had the best gameplay i have ever had. The controller
did exactly as i commanded it to do and i was having fun. Then it started again. The input that i was not making happen. So i bought new controller. Nothing changed. I have come to the conclusion that someone out there has figured out how to utilize the co
pilot function remotely. I feel like someone out there is co piloting and making my gameplay a living hell. I have basicslly given up on xbox. I have tried support and no one wants to belive me. Can someone help me stop this?
