NHTSA Complaint #11576951 — 2016 KIA SEDONA

2016 Kia Sedona 3.3L V6 Engine overheating due to head gasket failure and coolant leakage, which subsequently caused noxious fumes to enter the cabin of the car which is a health risk especially for people who suffer from asthma, chronic diseases, or other high-risk populations such as pregnant women or children. While travelling with my family of five (including three children), we noticed an intermittent smell inside the cabin of the car while the air-conditioning was turned on, which days later we realized were engine coolant fumes. There was no warning light or indication of head gasket failure with coolant leakage. We were all exposed to these engine fumes inside the cabin, which contain ethylene glycol, that likely caused two children to feel nauseous and an adult with diagnosed asthma felt headaches and shortness of breath. According to the CDC, breathing ethylene glycol vapors may irritate eyes and lungs (source: [XXX] ). Kia acknowledges that a coolant smell may be experienced in the 2016-2017 Kia Sorento’s vehicles equipped with the 3.3L V6 engine [XXX], which is the same engine that is equipped in the 2016 Kia Sedona. We confirmed the 2016 Kia Sedona experienced a head gasket failure from an authorized Kia dealership and repair shop.
