Who Should Buy Hyundai vs Kia?
If you want a sedan, lean Hyundai. The Elantra is the best sedan pick from either brand, and 2024 is the year to favor. Skip 2020 and 2022, because sudden engine failure is the big risk. It starts with heavy oil burning and can end in a seized engine with no warning light first. Check oil use before you buy. KIA's K5, Forte, and Optima all rate good, but Hyundai wins the sedan matchup.
If you need space, lean KIA. The Carnival minivan rates excellent, and 2023 is the year to buy. Check the power sliding doors and the liftgate, which owners report closing on hands or dropping partway. Soul, Sportage, and Seltos are solid SUV picks. For electric, be careful with both brands. The Ioniq 5 and EV6 both rate mixed, and both have loss of drive power tied to the ICCU. Avoid the 2022 EV6 and the 2022 and 2023 Ioniq 5. The Ioniq 6 rates good.
The Bottom Line: Hyundai or Kia?
Choose KIA if you are open to either brand, especially for an SUV or a family hauler. The Carnival is the strongest model across both lineups, and 2023 is the year to buy. Choose Hyundai for a sedan, with the Elantra as the pick. Cost should not decide it. KIA saves only about $5 a year, roughly $25 over five years.
