The KIA optima is pretty on the outside, but the quality will leave you stranded on the side of the road. I had a brake warning light issue since I bought the car and KIA tried 7 times to fix it. They finally replaced the entire front wiring harness. Two weeks later the car won't start sometimes (it may or may not start). KIA has been unable to repair the problem ( 2 and 1/2 weeks of diagnosing). They are giving me my broken car back to drive until they get an expert flown in (time unknown) to look at the car. They are also trying to blame the problem on an auto accident that was sheet metal only damage and to the trunk. Avoiding their warranty claims (In My Opinion). Run Away from this car.
Heated seats, navigation system, engine and transmission response (when the car actually runs).
KIA should honor the warranty given with the car,
engineer better/more reliable products and
improve their customer service representation given to their customers.
