Check your manual for required maintenance, I doubt it's anymore than an oil and filter change with a few visual checks of things and maybe a tire rotation too. Your manual has all the info in it. If you use your dealer don't let them BS you into any service that isn't required by Hyundai's maintenance schedule.
0.....I paid for my scheduled maintenance upfront and get it all done including 60000 service. ( oil changes every 3000 miles because of Florida heat and stop and go traffic ) I also extended the warranty to 100000 miles on all of the electronics including the radio head unit, steering wheel buttons and proximity key, a replacement proximity key is unbelievably expensive!
