Don't bother calling customer care because they'll tell you to go to the dealer. When you go to the dealer tell them that you want to register the car on the myhyundai site with your information, they'll have to open some backdoor program to do it but it can only be done there.I recently bought a used 2015 sonata sport too from an auction. I tried to register the car on the website but it seems the vin is already registered to the previous owner. What do i do in this case.
If you email them, it's much quicker. They'll need you to scan/email a copy of the purchase order, your license, registration.I just bought My hyundai from a used dealership andI tried to register my car but it says my Vin isn't valid. Try to contact customer care but the hold rate is long.
