What Owners Say
"Engine used excessive oil and after a series of tests, dealer replaced the engine"
Anonymous, IL (2017 Kia Optima SXL 2.0-L 4 Cyl turbo)"Excessive use of oil"
Anonymous, OH (2017 Kia Optima EX 2.4-L 4 Cyl)"for more than a year I noticed having to add oil between oil changes. Usually at least 1-2 quarts between service intervals. It took another year of painstaking visits to the dealership service department to document the oil usage. Finally it was approved for engine replacement. I was given a rental car and there was no cost to me. I did have to give up about 20 hours of my time over a year to get this done. Service advisor told me there are many Optimas that had same issue. I wonder how many people go to the effort of dealing with hassle of getting through all the documentation hoops!"

"I have misfiring cylinders for 4 years with this car. KIA refuses to do anything about it (including replacing the engine) and has advised me to buy higher octane fuel and fuel injectors."
