Hyundai Sonata fuel smell in cabin, particularly when stationary or in neutral on Hyundai Sonata

Some Hyundai Sonata owners report experiencing a fuel smell in the cabin, particularly when the car is stationary or in neutral, which may indicate a potential fuel system issue. This problem can arise from a fuel system leak, potentially located in the fuel tank, fuel lines, or around the fuel injectors. Additionally, a faulty gas cap seal may allow fumes to escape into the cabin. Some owners also notice a persistent burning smell near the engine bay, which could relate to the fuel system or other components. While the gas smell may not always pose an immediate fire hazard, it is essential to address it promptly due to the toxic nature of gasoline fumes, which can lead to health risks like carbon monoxide poisoning. It is advisable for owners to have a qualified technician assess the severity of the issue to identify and resolve the source of the fuel smell.
