Starter Solenoid problems of the 2006 Chevrolet Malibu

I have been complaining about these problems for years to my dealership and haven't received the proper help to get these problems taken care of. I have been having problems dealing with sudden loss of electric power steering. My car steering wheel will lock up as soon as I turn the car on or even in the middle of driving on the highway. This is a hazard and life threatening. I brought my car to the dealership, but they informed me that my car did not have a power steering problem. But my car was notifying me on the screen that it was my power steering and the wheel locks up as well as continues to shake. It is still currently happening and getting worse. My steering shaft makes a lot of noise and I can feel it in the steering wheel when I drive. My break lights as well as head light bulbs are always going out and keep having to buy new ones. I know they will g out sometimes, but how often mines goes out is not normal. The airbag icon on my dashboard as well as the reading on my screen shows that something is wrong with my airbag. I'm afraid that one day it will just explode in my face. I also have electrical problems with my windows and lights in my car. The windows get stuck and only one light in my car works (one of the overhead lights). I had my transmission checked out and they informed me there was no problem (but they told me that about me power steering) and I end up paying to get my solenoids replaced, but I was not reimbursed when I brought it in for the transmission recall. Like I've said, I have been trying to get assistance from the Chevrolet dealership for years with these problems, but they keep telling me I don't have any problems. I really feel my life is in danger with all the problems I am having with this car and I do not feel I am getting the necessary help I need. Can someone just please assist me and help get these problems taken care of.
