On December 28, 2023, the "Fasten Seat Belt" sign (rear passenger side seat) and sensor in my BMW x6 starting buzzing even though no one is seating on that seat. I subsequently brought my car to the dealership and the service consultant did an ocular inspection of my seat belt and looked inside the buckle with a flashlight because the seat belt will not lock in place. I was subsequently told that the metal that is supposed to hold the seat belt in the buckle is missing or stuck. Because at that time my car has 59,000 miles, I was told that the warranty has now expired (50,000) and that I have to pay for the diagnoses and fixing of the car seat. Now, the "Fasten Seat belt: sensor for the rear middle seat is also lighted and making the "buzzing sound" even though no one is seating in the middle seat. I believe that my seat belts have become defective and given that I purchased my car around May 10, 2020 - I should not have to pay for fixing seat belt problems for a new car given the safety need for these belts. I would like NTSB to compel BMW to fix my seatbelts.
