On 9/14/24 I purchased a 2024 XLT 3.5L EcoBoost from Ira Ford in Saco Maine. On 11/1/2024 I was on a road trip to New Hampshire and got a flashing wrench light followed by flashing check engine light with black smoke bellowing out of the exhaust. I pulled over and had the vehicle towed to the closest Ford Dealership, Ford of Claremont. The dealership stated that there was a Turbocharger/supercharger 'A' UnderBoost Condition as well as misfires on cylinder 4. There is a technical service bulletin for the turbo and the dealership did the repair as outlined by Ford in the TSB.

I got the truck back on 11/15, attempted to drive it back to Maine on 11/16 and I had the same loss of power and blinking check engine lights. I had it towed to the dealership I bought the truck and they said there were codes for misfires on cylinders 1, 4, 5, 6. They're now saying that the issue is a result of contaminated gas. They said they pulled a fuel sample from the tank, put it in a glass and it separated and had 'a lot of water and an oily substance' along with gas.

I feel as though something here doesn't add up. I always have gotten gas at the same Irving location for several years with no issues. I have not seen any news articles or reports online of anyone else experiencing issues with contaminated gas from the same location.

Any help or suggestions anyone can offer would be appreciated.

 

This is one of those situations where a few things might have happened..

If,,,,,,the company that delivers the fuel to the station brought some water with the load, you weren't the only one with problems.
Sometimes ,,,,if you ask if they had a water problem they might tell you and maybe not because now they will be expected to pay the bill.
Does your vehicle stay in a nice warm garage when home? Then the tank warms up nicely and you take it out into the cold and it cools and possibly pulls in moisture.
Anyway, now you are aware of these possibilities, it never hurts to put in a bottle of dry gas , with only ISOPROPYL alcohol to help pass the water through and not have it get captured in the fuel filter and freeze when the temp goes below freezing. 20 degrees below zero is routine for up in Maine, yes/no ?
This may be all old hat to you, but maybe just a reminder.
