Ford Ecoboost 2.0 L engine, ~95,000 miles. The check engine light came on while on a cross country drive and the diagnostic code was a cylinder 2 misfire. The vehicle would chug and sputter when started up and had trailing white smoke from the exhaust. The garage reset the code and replaced the spark plugs. 2 weeks later the engine started chugging again on start up, with white smoke and a smell of burning coolant. We took it to our mechanic locally who found coolant leaking into the cylinder. He reset the code and recommended we take it to the dealer. When I got the vehicle back, I checked the coolant to find that it was excessively low, presumably from it leaking into the cylinder for an unknown amount of time. We researched online and found that the occasion of coolant leaking into the #2 cylinder is a common problem with an incredibly large range of affected vehicles, and that the solution is to replace the engine. When I spoke to the dealership and described the problem, they confirmed that the only solution was an engine replacement and that it was routine for them. They quoted me $11,000 for the repair.
