Was told by my mechanic that the top of my fuel tank has a plastic lid that has cracked. the car is leaking raw gas. he said this is approximately the 5th car he has seen with this problem this year. it is extremely dangerous and the car could ignite if a stray spark (tossed cigarettes butt, etc) was near my car. the odor is extremely strong and 'headache inducing' if exposed for any period of time. the gas actually leaks out of the tank from the top when the car is on. the fumes are flammable but no actual gas puddle can be seen because the liquid gas evaporates in the heat.
