I owned a 2018 SXT for 6 years. I'm in sales and in that time put 156,000 miles on it. Reliability was very good and I had very few issues. I also maintained this car well. I spent a lot of time in the car for my job and was always happy with the choice I made. It was comfortable, quick, got good mileage and was a solid performer. On the highway I got around 32 mpg and in the city around 27 mpg so I was happy with these numbers. One of the very few issues I had was with the sunroof. Just before I got rid of it, it started infrequently not closing. There was no rhyme or reason to when it did it. I was told either the motor was going bad, or it needed to be removed and the track cleaned. Either way it would have been around $600. That came at the end at around 150,000 miles. All in all, I was very pleased with the car, and it was very reliable.

I bought Kia optima at 42K miles and the engine has been burning oil from day one. Now it has 92K miles and I have been putting a bout a gallon of oil every month. I contacted Ki dealer and Kia corporate with no help. Do not buy 2018 Kia optima or similar years with GDI engine. Google is full of GDI issue stories

I love my Kia but had issues with the floor mat not locking and it resulted in the floor mat sliding over the gas pedal and flooring it resulting in it to hit the vehicle in front of me deploying the air bags and I was injured.
