2023 Infiniti Q50

I am reporting a potential safety defect involving my leased 2023 Infiniti Q50, VIN [XXX]. In 2024, I brought the vehicle to the dealership because the passenger seatbelt warning activated even when the passenger seat was unoccupied. I was told the condition was caused by objects triggering the passenger seat sensor, and no further repair was performed. On XXX, I returned to the dealership for a routine oil change and again reported that the seatbelt warning problem was continuing. I was initially informed that a component in the passenger seat required replacement and that the defect affected the passenger-side airbag system. I was later informed by the dealership that the defect affects both airbags, not only the passenger-side airbag. The dealership advised that the required replacement part must come from Japan. As of XXX, the part has not arrived, the repair has not been completed, and the vehicle remains awaiting the necessary part. My concern is that the airbags may have been inoperative or compromised for an extended period after I first reported the related warning issue in 2024. My wife and daughter drove and rode in this vehicle believing its safety systems were functioning properly. Had the vehicle been involved in a collision, they could have faced a substantially increased risk of serious injury. I am submitting this complaint so NHTSA can investigate whether this is an isolated defect, a dealer diagnostic failure, or part of a broader safety problem affecting other 2023 Infiniti Q50 vehicles.
