Reliability, common problems and owner reviews for the Kia Sorento 2.4 GDI / petrol (Theta). Check this before you buy used.
The 2.4 petrol is the simpler, cheaper-to-buy alternative but thirsty in a heavy SUV and rare in Europe (most buyers wanted the diesel). The naturally-aspirated 2.4 here is generally dependable; note that the broader Theta II GDI family was subject to a high-profile bearing-failure recall on certain turbo/US-market engines, so on a GDI version it's worth checking the engine isn't an affected unit and has a clean history. Otherwise watch DI intake carbon and the usual coil/cooling items.
