Is a Used 2018 Kia Sorento Reliable?
The 2018 Kia Sorento is a roomy, well-featured three-row SUV at an appealing used price. But like its Hyundai sibling, it carries engine recall concerns that require verification before you buy.
2018 Kia Sorento Overview
The third-generation Sorento (2016–2020) offers three engine options: the 2.4L GDI naturally aspirated (185 hp), the 2.0T turbocharged four-cylinder (240 hp), and the 3.3L V6 (290 hp). It's available in two-row (5-passenger) and three-row (7-passenger) configurations. FWD and AWD are both offered. Used prices range $15,000–$26,000 depending on configuration and mileage.
Common Problems to Watch
- Theta II engine seizure (2.4L and 2.0T):Both four-cylinder engines share Kia/Hyundai's known GDI engine manufacturing defect — metal debris in the connecting rod bearings can cause oil starvation and sudden engine failure. Recall campaigns apply to many 2018 Sorentos. Check the NHTSA VIN database before buying.
- KSDS software update: Kia's Knock Sensor Detection System update monitors for engine knock and triggers a warning before catastrophic failure. Verify this software update has been applied at a Kia dealer.
- 6-speed automatic (2.4L) hesitation: Some owners report sluggish response from the 6-speed automatic in the 2.4L model. Usually calibration-related.
- Infotainment screen delamination: Early units reported screen delamination or yellowing at the edges. Inspect the screen carefully.
- Third-row access: The third-row seat is small and difficult to access — not a reliability issue, but manage expectations if you need true seven-passenger utility.
What to Inspect
Start with the NHTSA VIN recall lookup. Confirm both the engine recall and the KSDS software update are completed. Listen for any engine knock or ticking on cold start with the 2.4L or 2.0T engines. Check oil condition and level. The 3.3L V6 is not affected by the Theta II recall and is a safer choice if it fits your budget. Pull a Carfax and get a pre-purchase inspection from a Kia dealer or independent Korean car specialist.
Reliability Verdict
The 2018 Sorento's 3.3L V6 configuration is a solid buy — it avoids the Theta II engine problem and offers strong performance. Four-cylinder models are riskier and require confirmed recall completion. Budget for slightly above-average maintenance compared to Japanese competitors.
