Engine failure - limp mode - this is a known problem with the Ford F-150 ecoboost that Ford and NHTSA have yet to address/ issue a recall. I have owned this truck for less than a month and it has twice now gone into �limp mode�. Merging lanes on the highway and the engine failed, a complete loss of power and ability to accelerate. I was able to avoid a terrible accident and get to the side of the highway. After reading hundreds of complaints online from other f150 owners I was able to see that the dealerships and Ford know about this issue, but have yet to address it. I checked the spark plugs and they were from the factory, yet gapped incorrectly as others have stated. The throttle body also will have to be replaced. This is horrible practice by Ford and NHTSA should address the thousands of complaints on the issue. This is going to kill someone eventually. I will be getting rid of this truck immediately and getting a reliable truck like I had previously.
