I have now had to take my new Z4 in for the second time for the same problem. My airbag light and seatbelt light will come on even though I have the seatbelt on. Last time they replaced the upper belt assembly. Not sure what they are going to find this time but I suspect the same thing will be replaced. Anyone else having this problem? If it happens 4 times I will have to use the North Carolina Lemon Law to get a new car or a refund.
