I've owned 8 Explorers through the years and have NO problem with Fords quality. None of my Explorers required anything more than oil, lube, tires and brakes. My newest Explorer is my cherry red ST. I'm not having any problems with Sync, maybe because I haven't upgraded, and no problems mechanically. My old Explorers were passed down to my daughters and they all reached 200K miles without more than what I've already stated. I have faith in ford.
