I bought my Kia Optima new in 2002, and the problems have never ended. Immediately after purchase the brakes needed to replaced. They have squeaked ever since, even after many brake jobs. The rocker arm in the drivers side power window broke four times. I finally stopped getting it fixed and that window, along with the passenger side front and rear window, which also broke, are now permanently shut. The fuses in the dashboard keep blowing out. The power antenna no longer works. The cable that connects from my gas tank door to a button on the drivers side door, which when depressed, will make the gas tank door pop open, broke within six months of my buying the car. It has been replaced three times. Now, when it gets hot out, the gas tank door won't open. I have to open my trunk and pull a release cord in there to get the gas tank door to open. There is a filter in the gas tank fuel nozzle area that tends to disintegrate. When that happens I cannot put gas into the tank. It has been replaced five times. I don't like that it did not have remote locking/unlocking feature or at least a generic alarm system, as this was considered their luxury version of the car back in 2002. I did like how it looked very stylish.

The Kia Optima LX is a good car. Since I bought it in 2015 it has not given me any problems at all. It is a great car for gas mileage. Also, it is a 4 cylinder car but I feel that runs faster than that. It's built to be very comfortable, very spacious! When my family travels long hours in our Optima we don't feel squished or limited in space, which is nice. I love the Bluetooth and Sirius option that the car has as well. Many people might thing that the Optima LX is not a luxury car but for me the model and the things that it has inside makes it luxury for the price.
