Hyundai Tucson fuel smell in cabin, stalling issue, and poor fuel economy possibly related to loose oxygen sensor on Hyundai Tucson

Some Hyundai Tucson owners report experiencing a fuel smell in the cabin, which may be due to gasoline leaks, fuel pump issues, faulty piston rings, or problems with the fuel injectors. This issue requires prompt attention, as gasoline fumes can be toxic and pose a risk of carbon monoxide poisoning. Additionally, some owners report stalling issues attributed to worn timing belts, bad fuel systems, transmission problems, or engine knocking, highlighting the need for a proper diagnosis by a mechanic. Furthermore, poor fuel economy, often accompanied by a strong petrol smell, may result from high fuel consumption, injector issues, or fuel leaks, with excessive fuel usage potentially contributing to the gas smell in the cabin. While a loose oxygen sensor may affect fuel efficiency and emissions, it is unlikely to directly cause these symptoms. A comprehensive inspection by a qualified mechanic is recommended to accurately diagnose and resolve these concerns, ensuring the safety and performance of the Hyundai Tucson.
