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.
