Kia Sorento Engine Problems: Which Years Are Affected and Which Are Safe
By Caropsy · July 1, 2026 · 5 min read
The Kia Sorento is a well-liked midsize SUV with a strong overall value proposition. But like its Hyundai siblings, certain years of the Sorento were caught up in the Theta II engine recall — the same issue that made the Hyundai Sonata and Santa Fe potentially dangerous on certain years.

Best years to buy used
2020–2024 (4th gen, new engine)The 4th generation Sorento introduced new engine families (2.5L turbocharged four-cylinder, 2.5L Smartstream, hybrid) that are not affected by the Theta II recall. These are the safe years to buy.
2019 (3rd gen, pre-recall engines)The 2019 3rd gen also generally avoided the worst of the recall exposure. Verify the specific VIN through NHTSA before buying.
Years to think twice about
2015–2018 (3rd gen, 2.4L Theta II)These years with the 2.4L Theta II GDI engine are within the recall window. Metal debris contamination from manufacturing can restrict oil flow and cause engine seizure or fire. Run every VIN from these years through NHTSA before considering a purchase.
2011–2014 (2nd gen, some Theta II exposure)Some 2nd gen Sorentos with the 2.4L engine fall into the extended warranty window. Verify the specific VIN.

Common problems to know
Theta II engine recall (2011–2018, verify): The headline issue. Check NHTSA.gov with the specific VIN before buying.
Transmission smoothness (early 3rd gen): Some owners reported shift hesitation on the 2016–2018 transmission. Less severe than the engine issue but worth noting.
Infotainment: Older UVO system is dated but functional — more of a comfort issue than reliability.
Bottom line
Buy a 2020 or newer Sorento and the engine recall isn't a concern. Any 2015–2018 Sorento needs a VIN check and documented recall completion before you consider it.
