Massey- Yardley Chrysler - Jeep - Plymouth sold me a lemon Plantation Florida

I bought a used 2006 Chrysler 300 from Massey-Yardley in Plantation, Florida on 11/26/2006 with 23,461 miles on it. At the time of purchase I had the balance of the factory warrenty which was 36,000 miles. While under the warrenty I had the transmission repaired twice. I have always took my car to get oil changes on time and have taken very good care of it. I pay close to $400 a month for this car. This is the first nice car I have had my whole life. Last week the engine started to make a noise so I took it to the service department and they informed me that I need liptors, 6 rocker arms, 2 pistons, 4 shafts, an injector service, and a tune up because my platinium spark plugs are foiled. When I purchased the vechile they told me that I would not need a tune up until the car had 100,000 miles on it. One week prior to my car making noise I took it in for an oil change and everything was fine. My car currently has 41,000 miles. They want $1385 plus tax to fix it. Yesterday I had to walk my kids home from school in the rain. I am outraged by this. There is no way I can afford to pay to get this car fixed, that's why I pay so much a month so I wouldn't have this problem. I believe that they knowingly sold me a lemon. When I called the corporate office and spoke with a manager over there, they declined any assistance in getting my car repaired. I don't know what to do from here..
