Since I work out of my house with a couple of road trips a year I will probably put on 6,000-7,500 miles a year on a 2015 3.8. How does Hyundai treat maintenance related to miles vs time. On my Avalon, the Toyota dealer always said by time. I found a good independent mechanic he would check the appearance of fluids, etc. and said unless the time period was extremely long he would go by miles (he also saved me money). What do Hyundai dealers do?
