Howdy folks. Just wanted to share my story with our 2015 limited with ecoboost. About a month ago I noticed that the truck seemed down on power. I had just crossed 50,000 miles (I am the original owner) and it just felt under powered. About a week later I get an engine code (I believe P209). I had the code read and it came back as under boost. I took it to my dealer as im still under factory powertrain warranty. The finding were something to the tune of one of my turbos had rusted and wasnt spinning fast enough. They stated it was a known issue and the new turbo addressed the issue. They had my truck for two weeks to replace the one turbo. I personally spoke with the tech to ensure the other turbo wasnt suffering from the same issue. He said the other turbo was fine and he installed some type of screen that Ford does now to address the rust issue. All was well with the world, so I thought... Exactly one week later I could swear it felt under powered again. The next day sure enough I get a check engine light AGAIN... Had the code read and it is the exact same code as before. I dropped the truck off this morning back to Ford. I have a feeling the second turbo failed just like the first. We had planned on keeping this truck until just before it hit 100k but now I am nervous as hell. Has anyone had turbo issues? Considering this was the first year for ecoboost on the expedition I have a feeling we bought the begining of the learning curve.
