Carrier/rack problems of the 2018 BMW X3

The vehicle is equipped with blue tooth, thus it is supposed to be hand-free to handle smartphone call or text while driving. This blue tooth worked properly for previous years models, and even 2018 same model but with the option being slightly different than mine, such as, the one equipped with wireless phone charger. For my vehicle, it does not notify while blue tooth connected when new text comes. I complained to BMW north America. They admitted that it was a firmware bug, but did not commit to update firmware to fix the the bug. This bug could side track the driver if he tries to check the message while driving since he knows the text message notification in the vehicle is not working.
