Warranty transfer/actual start date
 

Hi there. Just purchased a used 2014 Hyundai accent less than a week ago. Now it is making a loud sound when accelerating. It goes quiet once I maintain speed. The dealership I bought it from says it is still under warranty with Hyundai until November 8th this year. Hyundai didn't want to confirm my warranty status over the phone. Anyone know what my rights are and what to expect when I show up at the Hyundai dealership? I don't want to pay if I don't have to.
Thanks!!
