Air Bag Not Deploy problems of the 2012 Ford Fusion Hybrid

Above car shows light indicating that passenger seat airbag is turned off when my wife is seating in seat. This occurs approximately one out of five times. The light does not go off. Being a hazard to my wife I had crater lake Ford, medford, or check it out. They did the factory tests for calibration and found no problems. They said my wife does not weigh enough. Her weight is approximately 98 pounds. They further said it is a "safety factor for the airbag not to deploy in an accident since there would be more harm from the airbag than otherwise". A ridiculous statement since the airbags are protection against hitting windshields or other hard objects in the car. Would you please help me resolve this issue with Ford. Note- a complaint was filed with Ford factory on 7/29/15. No resolution from that complaint.

The contact owns a 2012 Ford Fusion Hybrid. The contact stated that while driving approximately 35 mph, the power steering seized without warning while steering through a curve. As a result, the vehicle crashed into the side of a tree and went down into the canal. The air bags did not deploy. A police report was filed and no injuries were sustained. The vehicle was towed to a salvage yard. The manufacturer was not notified. The approximate failure mileage was 47,000.
