Tl* the contact owns a 2016 hyundai elantra. The contact stated that there was an internal exhaust leak and a strong fuel odor was present in the cabin and trunk of the vehicle. The contact became ill and nauseous due to the failure. Medical attention was not received. The vehicle was not diagnosed or repaired. The manufacturer was notified, closed the case, and did not provide an explanation for the odor. The failure mileage was not available.

Car has begun to malfunction after only three years of ownership. There were no warning signs of a faulty engine or overheating. In december of 2020 I took the car to get an oil change, it is now january 2021 and I have had to add oil to my car due to an overconsumption of oil. After taking it to hyundai I am now being told that the car might need to have the piston rings replaced which would require an engine rebuild or a whole new engine. The car malfunctions on the road as well as when it is idling.
