What Owners Say
"The car had an oil consumption problem and the engine had to be replaced."
Anonymous, TX (2018 Kia Optima EX 2.4-L 4 Cyl)""The car is burning oil. There are no leaks on the ground. I have had to add a quart of oil every few thousand miles between oil changes. I have owned many other cars. This is not normal. I insisted the Kia dealer I purchased the car from complete an oil consumption test which they were reluctant to do, though they admitted having to replace some Kia Optima engines due to excessive oil consumption. My car goes in for testing in two days.""
Anonymous A., IL (2018 Kia Optima LX 2.4-L 4 Cyl)""Car uses a lot of oil, 1/2 qt per tank of gas""
Anonymous, CO (2018 Kia Optima LX 2.4-L 4 Cyl)"Car burns oil very quickly. Have to replace the oil about a month or two early"

""Since Kia diagnosed my engine problem and confirmed it was under warranty in November 2024, Kia has mandated that I drive it 1,000 miles for three separate periods before they will tell me if they will honor my 10-year warranty. Carbon deposits in the engine that have hardened around the pistons are the problem, so Kia has told me.""
