For the past several months, I have had a problem with a faulty with the gas cap. The alert I receive on the car states that the gas cap is loose, then the engine light goes on. I have had this issue thoroughly checked out by my mechanic and he is stumped as to how to fix this. We have replaced the gas cap several times, he has performed numerous checks to see if there is a leak in the gas tank or fuel lines, all to no avail. He cannot detect a leak. I have spent over $1000 trying to fix this problem. The problem remains unfixed and with the engine light and fault active, this vehicle does not pass state smog.
