2018 Lincoln MKC Engine Problems

“I have the 2.0L EcoBoost I-4 (assembled December 2017, engine block part number HV 206 AA) in my 2018 Lincoln MKC Black Label. The head gasket failed at 37,000 miles in May 2023, according to my Ford/Lincoln dealer. It started as intermittent misfiring/running rough with the check engine light illuminated. My scanner detected the code P0301 cylinder one misfire. My coolant reservoir tank level also gradually decreased, with no visible leakage. …”

“Kirk Brothers ford supposedlly put a new engine in my vehicle. I've had issues with it ever since they supposedly put the engine in. I had another mechanic just look at it on 14AUG25 and he informed me that the engine was shot.”

This time, it failed in July 2024 after less than 5,000 miles. Like the first engine failure, the check engine light illuminated, but this time, the code I saw was P0300 random cylinder misfire. Like last time, the dealer performed a cooling system pressurization test, and the engine failed the test. …”

“1st Engine Failure Dec 2021 due to coolant intrusion and the long block engine needed to be replaced. After the repair I came to look at it & I found, Bolts were missing—including from the undercarriage, battery mount, & power steering reservoir, splash guard, inner wheel well shield. Tools (10mm Snap-on socket & unidentified loose bolts) were left inside the engine bay. The coolant hose came loose, which your team tried to charge $4,000 to fix, despite it being clearly related to poor installation of the engine. …”
