NHTSA Complaint #11706002 — 2015 KIA FORTE

The vehicle began experiencing persistent engine misfires and rough running. Fuel contamination was found in the engine oil, and the spark plugs were fouled with oil and fuel. The catalytic converter has become clogged and failed multiple times due to excess fuel and oil entering the exhaust system. The Kia dealership documented these conditions but refused to perform recall-related engine repairs. Kia Consumer Affairs stated the vehicle does not meet warranty extension guidelines and would not repair the engine. Due to fuel in the oil, misfires, overheating exhaust components, and repeated catalytic converter failure, the vehicle is unsafe to drive and presents a potential fire risk.
