Consumer Reviews for the Kia Optima
Read recent reviews for the Kia Optima
Keeping up with Honda and Toyota
Viper122, 03/12/2018
2018 Kia Optima SX Turbo 4dr Sedan (2.0L 4cyl Turbo 6A)
Update 3/2022: One issue that has come up is the car is now going through one (1) quart of oil every 1,000 miles. It’s within tolerance for Kia. I believe this is a turbo issue but there’s a process to go through with Kia before they start addressing it and I’m not willing to spend the time on that. It’s making me re-think a Genesis/Stinger purchase. It’s a hit-or-miss issue. Otherwise, … Car has been flawless for the 4 years I have owned, including all the tech (car is fully loaded). Updated review 3/12/2021. I purchased this car new in February 2018. It has been virtually problem free. I had a recall done, so have the unlimited engine warranty. The only issues I've had are: 1. A/C went out on a long road trip. Stopped to eat. Came back on when we started up again and have never had the issue again. 2. Part of the underbody cover (the felt piece) got caught on something and ripped off. Let alot of noise in. $120 part; dealer installed for free. No other issues. Car has been fantastic, looks fantastic and the interior still smells new with that Napa leather. I have an SXL in Sangria color with the Ivory Napa leather. Classy, great looking car.
