2015 BMW 335I Forward Collision Avoidance Warnings Problems

My car randomly stiffens steering in a turn which made me nearly hit a parked car and lit up a warning light stating “Drive Moderately”. The car recently also began to have symptoms of clunking and grinding when turning the wheel at low speeds. While this issue has recently arrises, my forward collision warning, blind spot detection, and lane departure warning safety features turned off completely i'm assuming as a result of the issue. The car also clunks and makes the same noise when turning the wheel side to side if the car is completely shut off as well. I’ve been referenced to SIB 01 26 18 and contacted both a BMW Service Center & BMW NA. Both tell me my car suffers from no symptoms, issues, and/or recalls; I tried to argue the fact that it clearly states that the page was more of a reference for models instead...
