Business ProfileforJohn L Smith Used Cars

I went to this dealership and purchased a 2015 ****** ****** in June of this year. approx. 3 1/2 to 4 months after purchasing this car it started to jerk as I was driving, like it was struggling to accelerate. I contacted the dealership and I was told to bring it in. I went on a test drive with the same gentleman that I purchased the car from and he was able to feel and see what I had explained to him over the phone. He then proceeded to tell me that it felt as though it was a misfire and I needed a spark plug. The dealership kept my car for approx. 4-5 days and when they called me and told me it was done, I was told that only issue was me needing a oil change and brake fluid. My car continues to do the same thing and now is struggling to start and cuts off completely while i am driving. My warranty for the vehicle is now up and I use my vehicle for work. If i put it in the shop I cant make any money to pay the car payments and I cant make the money to pay for whatever needs fixed. I am very upset that I'm having these issues with this car after only having it for approx. 4 months. I know my car will not do this because i need a oil change and brake fluid. I've taken it to a mechanic and he feels as though i need new spark plugs, a cam shaft sensor, and a crank sensor. I also spoke with a different mechanic and he said it may be my fuel pump. He said to try to fuel injector fluid and see if it helps. I should not be having this issue at all. I have a family member that purchased a car from them and her car has not been out of commission for over 1 year. I still gave this dealership the benefit of the doubt. And i also feel like that person that sold me my car isn't very considerate or helping. I'm very frustrated and i just want my car fixed.
