After driving for decades, I've found that the smell of gasoline in the cabin is usually caused by a fuel system leak, such as a loose fuel tank cap, aging and cracked fuel lines, or slight leakage at the fuel injectors. Another common cause is an issue with the charcoal canister system. The charcoal canister is supposed to absorb gasoline vapors, but if it becomes clogged or fails, those odors can drift into the cabin. When the air conditioning is set to external circulation, it may also draw in external odors through the intake. This is very dangerous because a strong gasoline smell can pose a fire risk, so if you notice it, you should stop immediately and inspect the vehicle—don't continue driving. It's advisable to regularly check the fuel lines and seals during maintenance to prevent small leaks from turning into major problems. Safety comes first when driving, and regular maintenance can save a lot of hassle.
