NHTSA Complaint #11522454 — 2017 LINCOLN MKZ

I have a 2017 Lincoln MKZ with the 2.0T Ecoboost engine and have approximately 74,000 miles on the car. I have been receiving a check engine light which indicates a Missfire on Cylinder 2 when scanned. Additionally I have noticed low coolant levels in the reservoir. I have had a loss of heat in the winter which lead to the initial discovery of low coolant. No indicator light came on when the coolant was low. I replaced the spark plugs in all 4 cylinders which has not solved the issue. Additionally, I still experience coolant loss. I took the car to the Ford Dealership which informed me I have coolant leaking into Cylinder 2 which will require a new engine. Had the coolant not dropped as low as it did in the winter, I would not have noticed the loss of heat and therefore checked the coolant level as there were no other indicators of low coolant level. This could have caused significant overheating issues and even complete engine failure.
