In NYS, do I have the right to a refund for a gently used car repaired twice and purchased 3 weeks ago?

I bought it less than 3 weeks ago and it is now in its second round of repairs. First the gear panel stopped working (it moved in park, didn't accelerate in drive, and wouldn't go uphill) and the dealership took it in and told me an axle popped out and it was "repaired." I was still concerned because I read that it could also be a transmission issue. They took it back to appease me. After a day, they called to tell me they too didn't think it drove as smoothly as it should so they'd like to keep it a bit longer. It had less than 11,500 miles when purchased. The owner of the dealership is refusing a refund and if I understand the NYS lemon law correctly, he has 4 attempts of repair it before he HAS to return my money. But, at this point I do not feel safe driving it as a car with such low mileage should not have so many problems and I would like to not deal with this dealership at all. It was not until I became irate and aggressive that they even began to pay me any mind.
