Man I'm glad you've had good luck with yours, and I honestly felt like I was an exception until my dad's timing chain buzzed at about 10k, and then my grandma's 3.5 Expedition did the same thing at about 40k. Maybe we are just cursed, because I know lots of people love them!Man, sounds like a bad egg. May be more than just yours, but I drive the Sh*t out of mine and hasn't had much of a problem at all. 2015 XLT 3.5 ecoboost fx4 bought with 29K miles. I have it up to 150K and it has not had any major issues. Just my experience.
