Fuel leak after filling car up.
Vehicle had approximately 50,000 miles when engine service light came on. Took vehicle to dealer who noticed gasoline leaking on the ground under the gas tank. Gas tank was removed and dealer found that the o-ring sealing the fuel pump to the gas tank had slipped allowing gas to leak out when the tank was full. The service rep said I was very lucky that nothing had ignited the leaking fuel.
