The adaptive cruise control keeps faulting randomly and triggering the seatbelt warning ??. Also when the adaptive cruise control fails the cruise control disengaes altogether. This is very dangerous when driving. I have taken this car to the dealership 4 times within 2 months for this problem and no one can fix it.
