Steering Is Tight problems of the 2009 Dodge Journey

The failure that occurred on Feb 12,2016. Put the life of my child and myself in eminent danger. While traveling 70 mph in the high speed lane, with moderate traffic on the highway, the car sudden shut off. The dashboard went black, the engine stalled and the car became almost impossible to drive. Not one indicator light on the inside or the outside of the vehicle worked, I reached for hazard lights that did not respond, the gas pedal was unresponsive. The steering was slow and hard to use- power steering was not available. Brakes seemed slow to respond. I know for certain had I collided with any item the airbags would absolutely without a doubt not deployed. The car had simply decided to "shut off", I put the car in neutral hoping to continue rolling forward down the highway with traffic. I was able to muscle the car to safety on the side of the road. I placed the car in park , and turned the ignition to the off position. After several minutes of calming myself and my daughter down I restarted the car. It started, however now every light that can illuminate on the dash, the wipers, day time running lights, radio, and door chimes in a 30-40 second repeating pattern. The dashboard indicates that the car is in park, reverse, neutral, and all forms of drive at the same time. The speedometer, rpm gauge, gas gauge , oil pressure and temperature gauge bounce from the minimum to the maximum during the cycle. The car has clearly had a extensive electrical failure- the "main computer" - as I dont know the exact component that has failed is no longer able to determine whats going on. Having this terrifying failure with my daughter in the car caused me to google the problem, im not the only owner this is a reoccurring situation for many owners. Im just so thankful to have walked away unharmed.
