How often do you get your car serviced? I am averaging about 600 miles per month since I bought the car in August. I spoke with an independent service company today the suggested getting the car serviced every 5,000 miles instead of 7,500 as Hyundai recommends. I always brought my Prius in every 5,000 miles for 15 years, but I never used synthetic oil like the Ioniq has in it. I would appreciate your thoughts.
