My wife, 78 years old, is petite. She weighs 75 lbs, height 4'10." The front passenger seat sensors don't register her as sitting in the seat with the result that the passenger air bag is not engaged (the dashboard light indicates the air bag is OFF). My vehicle, 2021 Acura RDX, passenger seat has 2 seat sensors while the MDX model has 4 seat sensors that would register her weight and the air bag system would be engaged. We have not had an accident. The MDX seat is not compatible with the RDX. Acura says that nothing can be done to rectify the problem. I consider this problem a safety defect.
