KIA Sportage — What to know
The Sportage is a practical crossover with improving reliability over generations. The third-generation Sportage (QL, 2015–2021) with the 2.4L GDI Theta II engine was subject to engine failure recalls due to metal debris from manufacturing. Verify any recall status on older examples before purchase.
Specifically for engine replacement on this model:
Third-gen Sportages with the 2.4L Theta II GDI engine (2016–2018) were part of an NHTSA investigation and Hyundai-Kia recall due to engine bearing failure from manufacturing debris. Symptoms: knocking noise, loss of oil pressure, engine seizure. If any recall was not completed, it should be the first priority. Fourth-gen (NQ5, 2022+) Sportage uses a completely different engine family with no known bearing issues.
