I logged an identical issue with Support today. I bought the game and all DLCs yesterday, and get constant "Steering Misbehavior" alerts when using an XBOX controller. I got a response from the Support team that the most recent update of the game introduced this bug. They also suggested I re-install and delete some files as an interim fix. The interim fix did not work, so I'm waiting for this to be patched.
thanks so we will wait..
