: the contact stated the odor of gasoline was noticed around the vehicle. It was driven to the dealer, who determined the fuel line on the engine rubbed together with the transmission cable causing a hole in one of the hoses, which needed to be replaced. The transmission cable rubbed a hole in the fuel line , which caused gas to leak onto the engine. Updated 01/10/07.
The fuel gauge system indicator always read full tank even when the tank was empty. Dealer notified.
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.
