They have constantly tried to stay on top of the issue. I know when I got my turbos replaced with the newer/revised turbos the dealer said that mine will be the last one they do for a little bit because they were working on another revision to the latest part at the time.I'm familiar with the issue with you're talking about. Did my research on the ecoboost while deciding on the Bronco. My understanding, it was isolated specifically to that 3.5L and Ford corrected the issue in later model years. Sucks you got stuck with it, but it seems every time someone wants to prove the ecoboost has reliability issues they point to the early 3.5L which is a small population of the overall # of ecoboosts out there.
