Hi all. I bought a brand-new 09 Mercury Mariner in May. Since then, it has died on me twice while idling. The first time, I thought it was just a fluke. The second time, yesterday, I took it to the dealership. Now they are telling me that the fuel tank vapor canister has raw fuel in it and that the only way this could have happened is by topping off the gas when fueling, which I never do and have never done. They are refusing to honor the warranty and telling me that I have to pay $400 to fix the problem. The vehicle has less than 10,000 miles on it and they won't pay for the fix. I'm flabbergasted. Anyone else have the same problem or have any ideas on what I can do? Any help would be much appreciated.
