2024 BMW I7 Steering Problems

This is the 4th time I am having issues with this car. Major safety issues. Yesterday during during on the 405 freeway. It suddenly started to rain, the wiper malfunction while in traffic and pouring rain. A week before this incident, the steering of the car kept moving suddenly out of my line. This time my son was in the car. These dealerships do not really care to even look at it, they drive the car for 2 miles and return it with a no problem found issue. Enough is Enough. The last time it was taking to the dealership after the automatic brakes would engage suddenly, they advise me that car was taken to a mechanic which is ridiculous. I am not in communication with BMW head quarters and they keep telling me to wait for a decision. This is not a waiting decision.
