NHTSA Complaint #11454790 — 2018 LINCOLN MKC

Misfire cylinder2 coolant found in combustion chamber requiring longblock engine replacement. Through investigation found that this is a widespread factory defect that Ford is well aware of. A diagnostic check was not performed on this issue during any routine service visit even though a technical service bulletin had been distributed to dealerships in 2019. The dealership and Ford customer service personnel all confirm there was nothing an owner could have done to prevent this result. An engine light came on at 77,000 miles, just 7,000 miles outside of the warranty.
