Radio/tape Cd Player problems of the 2013 Chevrolet Silverado

We have many problems with our truck. I dont remember all the dates so I am starting with the most recent and will work back. On 7/17/14 I was driving down the highway when the steering wheel of my truck locked up on me and the truck would no longer accelerate. I could no longer steer. Had I not been trying to make a lane change when it happened, I would have been ran over by 2 semis who then had to scramble to avoid hitting me. One took the turn lane while the other almost ran a car off the road to get around me. Everything else on the truck was still working, lights, ac, radio, windows, everything, just not steering. One time I turned on my truck and could not switch through the gears so that I could drive and the dash had no information on it (no compass, temp reading, mileage). It would move through the gears but it wouldn't drive. I had to turn my truck on and off 3 times before I could drive. Our driver side window no longer auto rolls down, our bumper is falling apart and we have never been in an accident, the drivers door leaks when it rains, and our door locks will occasionally not disengage so when we go to shut the door it just bounces of the latch. This has caused one of our doors to come off the hinges and almost fall off our truck. We have had all 4 door locks replaced and they are still doing it.
