NHTSA complaint #11328203, filed 2020-06, 200,000 miles“A spring in the driver's seat belt buckle failed, causing the airbag light on the instrument panel to illuminate and deactivate the air bag system in the event of a front impact requiring air bag deployment. The seat belt and buckle was required to be replaced. The air bag light illuminated every time the driver fastens the seat belt. The airbag light stays on and would not go off when the driver fastens the seat belt. The dealer traced this to a faulty seat belt latch. …”

NHTSA complaint #11119394, filed 2018-08, 107,000 miles“While waiting for red the light to change, the vehicle suddenly accelerated. The driver could not maintain control, the vehicle jumped the curb and crashed into a ditch. There was no diagnostic test performed on the vehicle. The air bag did not deploy, the electronic fuel shut off and did not engage and the seat belts did not tighten.

Ford claimed that fault is the driver's fault due to their foot being on both pedals at the same time.”
