Car consumes a lot of oil. Approximately 5 quarts per week-faulty engine parts allowing oil to seep into the combustion chamber. The oil is then ignited along with the fuel, creating blue-tinted exhaust smoke. It is burning out spark plugs which is then wearing them out and almost caused car accident when car started sputtering and would not barely go once pressing gas. Has been inspected by KIA dealership. Was told engine needs to be replaced-warranty expired and nothing can be done. Car only 2 years old when this problem started and they will not replace.
