Signs of a Faulty Gas Cap

Most gas caps are made out of plastic. When opening and closing the gas cap hundreds of times, this plastic can eventually break down and begin to decompose and crack. If your gas cap cracks or breaks, it can affect the way that the gas cap seals your gas tank.

Smells Like Fuel

Another issue that would hint of a faulty gas cap would be if there was a fuel smell coming from the vehicle. For reasons similar to the above, after a cap has failed there may be fuel vapors escaping from the cap that are then released into the air. If your car smells like gas it could be a serious issue that needs to be immediately addressed.
