I was driving and a strong fuel odor was experienced. When I stopped the car and looked under the undercarriage there was a puddle of fuel. There is a fuel leak coming from the bottom plastic underneath the gas tank. It may be the fuel filter as the same year and model had a recall but apparently my vehicle was not covered.
