You guys crack me up Turbo this Turbo that SCARY! How many hundreds of thousands of miles do Turbo Diesel trucks run? Most consider them super reliable. Gas turbos have been around a long long time. I would suspect something like a high pressure fuel pump or timing chain guides being plastic would wear out long before any turbo issues would cause a failure. Any DI N/A vehicle would have the same issues. Keep them cool, maintain the cooling system regular oil changes and they last a long, long time. My 3.5 Ecoboost in my King Ranch is a fantastic engine, nothing really Eco about it though. Fantastic power and smooth and can be.
I also have a 2007 Sequoia with a 4.7 with 239k on it with 2 timing belt and water pump replacements. All at a cost as well. Nothing is maintenance free, nothing. Buy what you like. Don't be scared of the Ford turbo, they didn't just put it in there and not test the heck out of it.
