My son and I both have 2018 Optima's. I am considering swapping cars with him. Mine has low mileage and his high mileage. He travels and needs a reliable vehicle and I dive my Optima less than 1k yearly. I have another car for my daily drive. Planning to change title and insurance to his name for liability reasons. Not sure how the dealer will handle the warranty should the car need repair. Since the car is still in my family, how would the dealership know the car title was changed? Do they access Department of vehicles records or depend on self reporting when a car changes title?
