Car smell like gas .
My car has 122530 miles.
Hey there, thank you for asking a question about your 2005 Saturn Ion. A "strong" odor of fuel is an emergency circumstance. If you park a vehicle with a known gas leak in a tightly closed space, such as a house garage, you literally run the risk of explosion or fire if you are unlucky enough to get a high concentration of vapors. Consequently, if you are detecting a strong odor of gas it does not matter "what" the cause is because it is simply a problem that has to be investigated and repaired as soon as possible. Just to give you some ideas though as to the cause, you could have an EVAP system (vapor) leak, a rusted steel tube in the fuel lines (pressure or return), a loose fitting, a damaged gas tank, a damaged (corroded) fill tube, or a similar problem with any of the many other components that make up the vehicle’s fuel system. Gasoline is extremely flammable - that’s why car engines are so powerful - and gas leaks are among the more urgent items when it comes to car repairs. Forgetting to change your engine oil won’t kill you or cause a fire, but a gas leak unattended to is obviously a different matter. I encourage you to have a certified technician from YourMechanic come to your location to inspect your car’s gas odor and make the necessary repairs.
