NHTSA Complaint #11453090 — 2017 INFINITI QX80

The passenger air bag system is apparently designed to disarm when a "small adult or child" sits in the passenger seat. This means each time my wife sits in the passenger seat (she is approx. 120lbs,) the passenger air bag light illuminates and the air bag is disarmed. This then renders one of the key safety features inoperable, and she and I feel very unsafe in the car. However, my research tells me that it is designed to be that way. How can that be legal or permissible? This design is deeply flawed and should be addressed immediately. She should not be endangered purely due to her being the weight she is. Not all Americans are over weight. No other car I own or have owned ever did that, only this Infiniti, and apparently all other Infiniti's.
