Steering Rack And Pinion problems of the 2015 Dodge Dart

I bought a 2015 Dodge Dart sxt with 32996 miles on it. Got the car on 4-4-2017. I had it not even a month and it's been one thing after another with it. First it dont shift properly it gets to a high rpm then it shoot you forward at a fast speed. Then a very bad knocking in the front end when you turn the wheel from left to right while parked. The dealership looked at it 3 times and couldn't diagnose it but did tell me it needs two up dates that would fix the shifting issue,then said I needed a new right shift axel and I asked them to check the right hub cause the other shop told me the hub was bad. Well they were right on that. So Dodge fixed those things for me. Then said my knocking was from the axel. Two days later its still knocking I had another shop diagnose the knocking to it was the (rack and pinion). I took it back to Dodge and told them and they argued and said no that's not it. Two days later they ordered a rack and pinion. Now the car has been stalling out on me,the shifting problem is back again. One the high way going 75 mph there is a terrible noise coming from tire area along with a vibration that I feel on my feet coming from under the car. Going around highway corners the back end feels like it's slides. All this with in 1 month of owning this car. This car is not and never will be safe for my kids and I,no matter how many times they try to fix it. I got invoices and everything document and I will be getting a lawyer for having to pay 15000 for a lemon when I told the dealership I wanted something else cause there is to many things wrong with it when it's only two years old. I was told no its to late I got all the messages saves on messenger from the sales men at the dealership. What do they expect me to do after the warranties up and it still has issues I can't afford that. I bought a new car so I didn't need to put money into it. This car is a lemon@iwillproveit.
