I’ve just experienced a similar problem which can be found in both Forza Motorsport 6 and Forza Horizon 3 concerning the Thrustmaster TX Racing Wheel. After playing around for probably 5-10 minutes suddenly the wheel starts to react strangely when rear wheel traction is lost by violently turning the wheel itself to the left. This occurs with ANY rear wheel traction loss, whether at speed or a standstill. This makes driving at all-especially precisely-impossible. I did notice this problem was non-existent on PC in the past two games, but I haven’t had the opportunity to test it with this game yet. This problem was a total annoyance in the past two games and has gone on long enough. It needs to be corrected before it gets overlooked again!
