Who Should Buy Kia vs Lexus?
If you want the lowest chance of trouble, lean to Lexus. Target the RX, and favor the 2022 model year, which has no recalls. Watch for an instrument cluster that dims or goes blank on that year. The ES, IS, TX, GX and UX also rank excellent. Be more careful with the NX. Pick 2021, and check 2024 closely, since it draws far more complaints than any other year.
Lean to KIA if you need a minivan. The Carnival ranks excellent, and the 2023 model year has far fewer complaints than 2022. Test the power sliding doors and the liftgate before you buy. The Niro and Sedona also rank excellent. Skip the 2022 EV6, which is tied to sudden loss of drive power from a failed charge control unit. The 2024 EV6 is the better pick, but newer years have had little time to show problems.
The Bottom Line: Kia or Lexus?
Reliability should be your first priority, and that points to Lexus. The RX is the strongest single model across both lineups, and the 2022 year is the one to favor. Repair costs also run lower on the Lexus side, though the data gives no Lexus dollar figure, so the five-year gap cannot be priced. If you pick KIA, choose a 2023 Carnival and inspect the doors and liftgate closely.
