Engine lost power on highway Engine light came on Towed to dealership and they told us the engine was bad, camshaft is gone and cylinder bad. Truck has 86,000 miles on engine; we do not allow it to be idle, and all maintenance and oil changes were performed. Note: Ford Rep did give us 50% of replacement, not sure how they come out with a engine tell you it's better than out going engine "more durable" and it last 86,000 miles. By giving us 50% they are telling me it will only last 160,000 miles when maintained which is a joke.

Turbo will over boost to 31 psi and the engine will go in to a fail safe mode reducing power to 5 miles an hour without warning. Causing you to have to pull to the side of the road and turn off the engine and restart to clear the fail safe mode. This has happen to me over 12 times. Ford has replaced the turbo twice under warranty. The problem seems fixed for the first 30 - 40 thousand miles. Then the same problem recurs. The biggest headache with this problem is it take weeks and some times months for ford to diagnose. Do to the fact that when this happens no engine light comes on and no fault code is stored. Ford will not warranty the part out until they get a fault code. The only time the truck will throw a fault code is when this problem happens twice on the same day. Most of the time it only happens once a day. I find this problem to be a major safety issue. Do to the fact that it happens without warning and you can't always make it to the side of the road under reduced power. Be it heavy traffic or no shoulder to pull off on. There has been 2 times that I had to stop in the middle of my lane and shut the truck off and restart it before I could regain full power.
