Steering Rack And Pinion problems of the 2011 Chrysler 200

My steering wheel became hard to turn. It was like driving manually. I took my Chrysler 200 to pep boys and they replaced the power steering pump. The steering was fine for a day then it went back to being hard to turn. I took it back to pep boys and they replaced the pump again. It lasted for three days and it went back to being hard to turn. I again retuned to pep boys and they then said that my rack in pinion had to be replaced. I could not afford to get the work done. I was told by Chrysler, that my warranty had expired and I would have to pay out of pocket. My car was not yet 2 years old. This was ridiculous. No one wants to take responsibility for the front end. I was told by a pep boys mechanic that they had worked on over 100 cars (Chrysler 200's) through enterprise rental and they had so many cars with the steering issue that they stopped working on them and just do the tune ups. If Chrysler knows about this then they should have repaired it. My car is still in this position. I have not been able to get repairs due to lack of funds. I still do not feel that I should have to pay for something that is wrong with a new car. Now I am having an issue with my turn signal. When I turn on my left turn signal, the dashboard lights dim. When I turn the right turn signal on, the dome lights come on. I, again repeat, this is a new car and I should not have to deal with these occurrences. I have had to change the battery in its second year, and replace the alternator. I look forward to hearing from someone. Thank you.

On July 18, 2012 I bought a Chrysler dealer this car, left over from 2011. I bought it as a new car. On highway trip I started noticing vibration in the car guide, and soon began to feel a noise as if something had loose near or connected to the front wheels of the car. After two visits to the dealer where I bought the vehicle report that has damaged the rack and pinion and I should wait two weeks for repair because they have no parts available in stock. I do not know if it is safe to drive the car in these conditions because it did not inform me.
