2014 Chrysler 200 seat belts problems

Tl* the contact owned a 2014 chrysler 200. While driving in the rain, the speed was unknown because the speedometer failed. The contact rear ended the preceding vehicle that had stalled and there were no warning indicators illuminated. The air bags failed to deploy. A police report was filed. The contact sustained a fractured right hip, bruising, lack of motion in the right wrist, a fractured left pelvis, bruising to the left knee, and severe bruising to the chest from hitting the windshield.

First I have noticed my car delays and jerks when putting it into gear. This happens mostly in the winter. More recently my car tried to accelerate a couple times while my foot was on the brake. I took it into the dealership to have it repaired and they stated because they could not make the car do the same thing, they could not fix the problem. Second the recall on the air bags and seat belts was first published almost a year ago. This is my only vehicle and I have two children that are placed in that vehicle.
