Sway Bar problems of the 2013 Chrysler 200

From almost the beginning of owning this car it has made a noise in the left front driver's side. The steering wheel feels lose, like it could come apart. I had brake issues also. The dealer was able to find the brake noise, but not the noise in the left front driver's side. They say there is nothing they can detect. Yet, my car continues to make this noise. Now, I'm not a mechanic, but my car should not be making a noise if everything is alright. Checked on youtube and many people with Chrysler 200's, 2013's are having the same problem. They say their mechanics either cannot find the problem, or it's 1. Steering column 2. Outer tie rod end or sway bar end links 3. Ball joints 4. Bushings can be worn on control arms of sway bar or 4. Tie rod. My dealer cannot find any of that wrong with my car, yet, I believe it is one of these problems. My car was purchased at moore, Chrysler, Jeep, Subaru, at 8700 w. Bell, road in glendale, arizona. I am a single lady, living on social security disability. My dad bought this car for me. I cannot afford to have all these problems fixed if the warranty runs out, and the dealer lets it. I need them to take responsibility and fix my car.
