Seat Belt Problems of 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.

We were driving north on I-75 and exited at highway m-24. As we turned rt. , the left front tire lost air pressure (lt. Front car tire was recently changed and not sure proper sealant was used when installing new tire) and the car suddenly shot to the left and we went over an embankment into a ditch for approx. 20 feet then shot up and over an expressway entrance ramp into a steel barrier. The seat belts were on both of us and the airbags deployed. We both suffered severe blunt force body trauma and had to be taken by ems to the local hospital. Recovery has been slow as whip lash and back injuries just don't seem to want to heal. On another note, my right ear was damaged by the explosion from the air bag deployment and now I have high shrill ringing 24/7 and can't sleep. I have been to hearing specialists and they say it is tenitius (spelling) but there does not seem to be any solution. Does anyone in government have any solutions? this is driving me crazy.
