Radio/tape Cd Player problems of the 2007 Chevrolet Malibu

2007 chevy Malibu electrical hell my car was completely fine aside from the power steering recall that was fixed on it. Then about 4 months later my car cranks but doesn't start! I was driving it 20 mins prior and then this happens. The radio,the lights, the horn and the dinging with the door open, all still worked. Unsuccessfully trying to start it I left it alone to get towed. 5 days later I received my car back saying it started just fine they can't detect what's wrong with it, because they couldn't read the code it gave out, and to keep notes of weird things to bring it back in. In doing so my car was fine for a month and a half, they're were no issues. The next time my car did the crank and no start I noticed the security icon lighting up, as well as the fact that I left my radio and air on. It's late at night, I'm alone and my car is failing me, after trying for 15 minutes I got my car to start. The third time is the worst time, by this point it's about 2 weeks after the 2nd incident. Same scenario, just drove it 20 mins prior and it was fine, then another crank no start for hours. Even tried to leave my key in to ignition. After hours I got it to start and making it home the car slowed down and came to a complete halt in the middle of an extremely busy street, putting on my brake lights I avoided getting rear ended. I took the key out and restarted the car and it started somehow. After getting it home I haven't driven it since and a number of more issues started happening. My locks have now started to make an obnoxious buzzing noise when getting unlocked, the service air bag notification will light-up on the dash and disappear quickly, all icons light up on dashboard , security icon flashes, check engine light is on, car will not start on crank, radio fades out and comes back on, horn is a faint noise. Reading similar complaints this is an outrage.

I was driving my car and the power steering lock up it was hard for me to turn and a display appear on my radio power steering so I took the car to the dealer and they diagnoised it stating that the power steering motor had went out and something about the steering column the shaft was bad this was in 2010. Again I was driving my car this is in 2014 the same thing happen I take the car to the same dealer and they diagnois it this time as a torque sensors but I new something was wrong they did not want the codes to be the same as before so they used another code which is the torque sensors. So I take the car to another chevy dealer and they diagnois the car and said the power steering motor is bad and the steering column is bad just like in 2010 and I no that this dealer is right because the car done the same thing as it did in 2014 as it did in 2010 the first dealer was trying to cover up that it was the same thing so they used different codes. I talk to gm and they agree with the first dealer and said there is nothing they can do I also wrote a letter to mary barra but I don't think she got it only the sec. I think its sad that they no that there's problem with these cars the 2007 Malibu and wont do anything about it.
