Consumer Description

Due to excessive oil consumption and blow thru to catalytic converter, and burning of oil in the converter clogged up my catalytic converter as seen in pics causing exhaust fumes to enter cabin and engine not run properly. Driver or passenger must open windows to get fresh air. I had to have converter replaced. There is still periodic fumes that enter cabin even with new converter because engine is still consuming excessive oil . This should be addressed to and rectified through KIA corporation. Thanks
