2001 Ford Focus steering problems

Ford focus sped up for no reason and then veered to left crossing left lane and went into ditch which had a culvert and the car then bounced into a cornfield. Airbags deployed for both driver and passenger. Driver had broken ribs and other bruises. Passenger had chest injuries from which he died couple hours later. The inspecting officer said witnesses insisted they did not see brake lights, and if there was anything wrong with the car the driver would have hit the brakes.

While in curve driving 50 MPH steering locked up, not sure if car cut off but I was unable to straighten out wheel resulting in accident where I hit telephone crushing pelvis, and breaking my left arm.. I spent 37 days in hospital and now have plates and screws in my pelvis and arm. It has been a month since the accident and I am now in a wheel chair for 2 months healing time before I can start therapy to begin walking, and doctors say I will have to have a hip replacement in the next 2 to 5 years.
