Summary Verdict
The 2018 Kia Sorento generally presents a reliable profile, particularly with its V6 engine and 8-speed automatic transmission, which show fewer reported technical concerns. The 2.4L naturally aspirated engine has seen some reports of oil consumption and knocking, while the 2.0L turbo can experience issues with the turbocharger itself. Transmission problems, though not widespread, can manifest as rough shifting in the 6-speed automatic. Electrical gremlins, such as infotainment glitches and battery drain, are also noted but typically manageable. Overall, the Sorento is a competent family SUV, but potential buyers should be aware of the specific engine and transmission variants and their associated reliability trends.
