What You Should Do
Check the gas cap first—ensure it is tight and not damaged.
If the smell persists, inspect under the hood for visible fuel leaks, especially around the fuel rail and injectors.
Look for wet spots or strong odor near the rear of the vehicle (fuel tank area).
Do not drive the vehicle if a leak is suspected; have it towed to a qualified mechanic for pressure testing and EVAP system diagnosis.
