Assist problems of the 2022 BMW X5

My lane keep assist shuts off every time I drive the vehicle. I reported this in February and was told it was just due to the weather (snow). I brought the vehicle back in a few weeks later to the same dealership and was told there’s something in the steering wheel that needs replaced and they needed to order it. They never called me back to tell me the part was in and did not reply to my inquiries. I took the car to a different dealership in August and again asked them to fix the lane assist. They again told me there was something called an agitator in the steering wheel and would need to see if they had any in stock or would order. After almost 3 weeks of being in the shop when I picked it up the assist shut off again 5 minutes down the road. I reported to BMW north America and did nothing about it. The gm from the original dealership emailed me to ask if I was satisfied with their service and reported the issues, no response. Nobody seems to be willing or able to fix this safety feature I have paid extra money to have.
