2013 Hyundai Elantra drivetrain & axles problems

On july 18, 2014, my 2013 hyundai elantra ran into a subway restaurant at 12150 s. Cicero, alsip, il. I was going into the subway parking lot, my goal was to park, but my car did not stop when I put on my brakes. My car kept going; it drove over the sidewalk, through the scrubs, and hit the building head on. Hitting the building is what stopped my vehicle, my air bag did not deploy.

Car starts but won't stay on, new battery installed, still doesn't turn on, in garage and is being towed to dealership. Windowshied fog constantly, and all f a sudden after 10 minutes and only way to defog---open windows., happens every am as driving to work on freeway or home at nights. The car is well maintained. Gas mileage is not 33 miles per gallon. Disappointed. Also sun roof doesn't close, was fixed, and still doesn't close all the way without me doing fancy maneuver with switch.
