Solution: This is a very common problem with any Ford Focus that was built between 2012 and 2013 that was fitted with 1.0-litre Ecoboost. The problem is caused by a leaking coolant, and it needs a new 'Degas' hose fitted. You can fairly easily check yourself if the Degas hose has been fitted, and if it isn't, you can get one with us.
“Specifically, the 1.0L EcoBoost engines have manufacturing, workmanship, and/or design defects which lead to a loss of oil pressure and an oil pump failure, causing the oil in the vehicle to slow or stop circulating, increasing engine temperature beyond specifications, and subsequently, causing the engine to seize.”
A design defect allows coolant to leak into the cylinders of the 1.5L, 16L, and 2.0L EcoBoost engine. Low coolant levels can lead to the engine overheating, misfiring, or catching on fire. Early EcoBoost engines were also known to catch on fire, leading to a 2012 recall and "stop driving" order from Ford. The Escape is a hot mess.
3 days ago · Ford has recalled the EcoSport and Focus with a 1.0-liter, three-cylinder EcoBoost engine due to a faulty oil pump that could cause the engine to fail and power brakes not to work.
2018 Focus 1.0L Ecoboost sudden oil pump failure. New to the forum. Trying to get an idea whether the oil pump failure is really common or not. I had 43,000 miles on my Focus when the engine light and oil light came on and the engine lost power and began knocking and idling rough. A Ford technician stated that this is due to the belt shredding.
