why do I smell gas fumes in my car ?

Hi, this is Bo, an auto expert on RepairPal's Car Genius team! If you’re smelling gas fumes inside your 2013 Hyundai Sonata, that’s definitely a safety issue. A gas smell can indicate a fuel system leak—either in the fuel tank, fuel lines, or around the fuel injectors. It could also be an issue with the fuel pressure regulator or a faulty gas cap seal that’s allowing fumes to escape into the cabin. The fact that it’s also difficult to start suggests a possible fuel delivery problem, which could be related to a clogged fuel filter or a failing fuel pump. Given the potential danger of fuel leaks, I’d recommend getting this checked out sooner rather than later to avoid any fire risks.
