Air Bag Light On problems of the 2010 Jaguar XF

When I purchased the vehicle from van Buick/GMC in scottsdale, arizona they assured that they repaired the vehicle, its recalls, and windshield. Upon leaving the dealership, a couple of weeks later, the service engine light comes on and the codes I received from autozone reflect airbag and fuel delivery system errors. Although the airbag light is not on inside of the cabin, the dashboard is starting to lift on the passenger side where the airbag is. Also the rear seat child seat anchors do not exist. They are not present in the vehicle and I have 2 small children I transport daily. Almost daily, the engine will stall or lag and I can hear whining coming from the rear passenger back seat where the fuel pump is. I'm afraid that the smell of gasoline and that sound means I have a faulty fuel pump. It stalls when running and when sitting idle. It's worse at an idle. It stalls or stutters daily. I'm afraid these 3 things which I've seen on recall lists related to this type of car were severely overlooked and are a danger to myself and my children.
