2017 AUDI A4 Seat Belts Problems

I have been experiencing something that might be related to safety recall 74E3, but i am not sure. I've been driving with my seatbelt on with no one at the passenger seat. But the seatbelt sign keeps showing up with the beeping sound, and the sign says Safety System Malfunction with front airbags off.... I called the Audi Fletcher Jones dealership in Irvine, California, the service team told me that they don't have the part to help fix this recall and there is nothing they can do. They also would not tell me when this recall can be fixed. I called a few other dealership in Orange County, California, seems none of the dealership has the parts to fix this. I have not yet encountered an accident, but felt risky driving the car now.

I RECENTLY PURCHASED MY AUDI A4 AND IMMEDIATELY HAVE HAD ELECTRICAL ISSUES. JUST RECENTLY THE BACK WINDOW WILL RANDOMLY ROLL DOWN AND LAST NIGHT WHEN I STARTED MY CAR THE SAFETY SYSTEM LIGHT AND MESSAGE CAME ON. IT STATED SEE OWNERS MANUAL. I BEGAN TO DRIVE AND THE LIGHT TURNED OFF. AS I DROVE IT BEGAN TO BLINK ON AND OFF THEN FINALLY STAYING ON AND MAKING IT DISTRACTING TO DRIVE.
