Unfortunately, many Optima and Sorento owners find that Kia’s dealerships are unable to timely fix their vehicles and their engines prematurely fail. 

Kia owners commonly complain of vehicle stalls and strange noises, before their engines completely fall apart.  For instance, one owner of a 2017 Kia Sorento described the issue as follows: “I leased a 2017 KIA Sorento EX V6 AWD on Feb. 23, 2017. Within two weeks, and less than 500 miles, there was a buzzing sound on start up that lasted for 5 minutes or so. The dealer I took it to took two days to diagnose the problem. The oil pump failed and the engine was full of metal pieces. The fix, replace the engine. This is the fourth KIA I have owned and it may be the last. I have contacted KIA customer support and they were not much help.”

Besides the issues discusses above, the Kia Optima has faced some serious engine reliability issues. Several of the complaints against the Optima mention excessive oil consumption, strange smoke from the tailpipe, and sudden stops. A user of the Optima 2016 model stated, “I was driving my car 2016 Kia Optima from Alpharetta to Decatur to attend church. I pulled into the parking lot of the church and parked. A few seconds after I parked, I began seeing lots of smoke coming from the right passenger side of the car. The police men who were in the parking lot directing traffic asked me to get out of the car quickly and began attempting to quench the fire with a fire extinguisher.” Another complaint against the same 2016 model was placed by another user, “My daughters 2016 Kia Optima is shutting off while driving. Sometimes it restarts after shutting down. Sometimes she has to hurry and put in neutral and restart as cars behind me don’t know the car has shut off. She feels very unsafe and is afraid someone is going to run into her. Took it to Kia dealer and they ran codes but nothing came up”. These issues can be extremely dangerous if not looked into at the right time.
