I bought this MKC Black Label with the 2.0L EcoBoost I-4 in December 2021 with just over 30,000 miles. Beginning around April 29, 2023, I noticed the engine started running rough, and the check engine light illuminated. I had a code reader, and it was the #1 cylinder misfiring.
Before this happened, since I purchased the car, the coolant reservoir tank level had gradually decreased without any physical sign of leakage. The engine was burning coolant. It took a few weeks to get it to the shop, and they diagnosed it as coolant entering the #1 cylinder and burning, as I thought. About a week after the diagnostic, a brand new 2.0L engine was installed, with an updated block design (third gen) designed to prevent the coolant intrusion problem the second-gen 2.0Ls had. This coolant intrusion problem affects specific years of Ford's 1.5L, 1.6L, 2.0L, and 2.3L EcoBoost I-4s.
Had this happened out of warranty, I would have been hit with a $8,000+ bill.
If you have a second-gen 2.0 or other variants of the engine, such as the 2.3, watch out. It's only a matter of time before your engine fails. My car's original one lasted just 37,000 miles and it was babied. If you're looking at a Ford/Lincoln vehicle with this engine with the defective block design, buy at your own risk and get an extended warranty.
For additional information there's a blog named Vroom Fume that discusses this issue more in-depth, it's definitely worth reading.
