I was travelling along the road when 3 cars suddenly hit the brakes really hard. I was able to hit my brakes fast, but I did not feel any pressure on the pedal and I was unable to avoid hitting the car in front of me. I also had a problem with the start system. I was randomly unable to start the car (about 3 times.) I would have to wait 10 minutes or longer for the car to be able to start again. I also noticed that the front bumper frame of my car was split in half (as if I had hit a post or something big.) I also noticed that there was writting on the front bumper frame (no foam padding in between,) and the following written on the front (DNR. 01/09/2017 and a time 10:20.) I don't know what's going on with my vehicle. It's frustrating and I've had to take it to the dealership a few time 3 hours away.
