Known problems on the 2017 Kia Sorento
Theta II 2.0T / 2.4L GDI engine $4,000–$7,000 to fix
If equipped with the 2.4L or 2.0T Theta II GDI (most were), this generation has a documented rod-bearing failure — knocking, then seizure or fire. Covered by huge recalls, a class-action settlement, and a knock-sensor software update (KSDS); a lifetime warranty applies to many, but only for the original-owner chain in some cases.
Check for: Cold-start knock/rattle that fades as it warms, oil consumption, a check-engine light for the knock sensor. Confirm the KSDS software recall was performed and ask whether the engine was ever replaced.
