2015 Jeep Compass engine problems

I was proceeding through a green light. A car coming from my left ran their red light at full speed (approx. 30 MPH) and crashed into my car. My entire front end was damaged. It was pushed in at least 10-12" according to the responding fire department & emt's my airbag should have absolutely gone off and it did not. I was transported to the hospital for neck pain. Luckily nothing is broken but I have severe neck, back, and head pain almost a full week later. I am starting physical therapy next week.

I have taken this vehicle to be looked at at the jeep dealership it was purchased from and at a local body shop. Both places claim there is nothing wrong with it, but every time we drive it on the highway and try to pick up speed, it stalls. There have been a few times when I am trying to pass someone and I begin to accelerate and my jeep will not increase speed and stalls as well. I have to put my foot all the way down on the gas pedal to get it semi moving.
