Since the middle of 2023 I have noticed a gas fume smell both inside and outside of my 2015 Mazda Mazda3 after I fill my gas tank to full. This smell persists up until I use about a half tank of gas or slightly less. I do not top my gas tank off and stop filling when the automatic gas pump stops. There are no visible leaks on or around the gas tank or below the vehicle, and there are no noticeable cracks around the gas tank, valves, lines, etc. Additionally, there are no warning lights present on my dashboard or any codes.
