Can I sue a dealership/manufacturer for selling me a 2016 with paint was altered on for almost $50,000 and they did not tell me when I purchased it?

I am currently living in Florida. I was living in Philadelphia when I purchased this car from New Jersey in April 2017. In July I noticed that the car was changing colors. I called the dealership where I purchased the car from to let them know the paint was coming off and there is another color under the white color. They blew me off continuously. So I called GMC and they opened a case and gave me a case number. Once we were able to speak with each other she told me she had to call the dealer. When she contacted me back after speaking with the dealer, she told me they were closing my case. She said the dealership told her they told me the car had been painted over and I was okay with that. I told her they never said that to me and it was not in any of the paperwork. I told her they sold it to me as a white Cadillac. She told me she had to go with what they said because they work together.
