Ford motor CO. Produced 2009 & 2010 Mercury Mariner vehicles' fuel system leaks gas when attempting to top off the gas tank. All Ford vehicles produced over the past two years may be affected. Ford will not fix the problem and tells the customer to not top off the gas tank although nothing is included in the owner's manual about this nor are dealerships admitting any knowledge about the problem nor has Ford sent any service bulletins to affected dealerships. All of the above has been confirmed on at least two occasions by my servicing Ford dealership.
