2012 Ford Fiesta brakes problems

I was driving approximatly 45 MPH on st rt 28 in milford ohio and my door was locked and the door ajar light failed to indicate any failure in securing the door apropiatly, well as I began braking to reduce speed my door flew open and I reached out to shut it as I was applieing pressure to the brake and they completely failed causing me to rear end the vehicle in my front, upoun impact the air bag on the drive t side only failed to deploy therfore causing a sustantially greater amount and longer lasting injuys.

Today, 1/19/2016 is my 6th visit to ford dealer service since 2014 august. My car has been towed in to service location with condition of transmission shudders excessively. I was not able to drive the car with a in-operating transmission. It is very sad, I do not feel safe to drive the vehicle no more than 15 miles if I can. Transmission and clutch has been fixed for 3 times. Every time I have talked to ford customer rep.
