Rough idle at start up persisted as I got onto the road and caused near complete loss of drivability as "check engine" light appeared for the first time. Had towed to mechanic who replaced coils and plugs. One month later, check engine light appeared again. Brought back to mechanic who looked it over and said it was fine. Two weeks later, third apperance of check engine light. This time, I took to Lincoln dealership who ran appropriate diagnostics and confirmed one week later this is the coolant intrusion defect that will require a long-block engine replacement for $12,500. Car has 55,000 miles.

The ABS brake module caused the brakes to lock up causing major damage to the right front brake assembly. Car was towed to the Ford/Lincoln dealer. Dealer said additional brakes also were locked up. The car had to be put on dollies so it could moved to a service bay. No warning lights came on. If this had happened at a higher speed it would have caused loss of control. The ABS module has since been replaced and reprogrammed.

I own a 2018 Lincoln MKC equipped with the 2.0L EcoBoost engine. The vehicle currently has approximately 72,326 miles. The check-engine light initially illuminated and an OBD scan produced code P0303, indicating a misfire in Cylinder 3. No other diagnostic codes were reported. Following mechanical evaluation, all four spark plugs and ignition coils were replaced. Approximately 145 miles later, the check-engine light returned with the same P0303 code. The code was cleared to confirm recurrence, and approximately 111 miles later the check-engine light illuminated again. I subsequently took the vehicle to a Ford/Lincoln dealership for further diagnosis. The dealership determined that coolant is leaking into Cylinder 3 and advised that the required repair is replacement of the engine/long-block assembly, at an estimated cost of approximately $8,900. I have since learned that Ford issued Technical Service Bulletin 19-2346 addressing certain 2017–2019 Lincoln MKC vehicles equipped with the 2.0L EcoBoost engine that may exhibit coolant intrusion into the cylinders, an illuminated malfunction indicator lamp, and misfire diagnostic codes including P0303. The prescribed repair under the bulletin may require replacement of the long-block engine assembly. A search of NHTSA's recall database using my VIN does not presently identify my vehicle as subject to a safety recall for this coolant-intrusion condition. I am submitting this complaint so that NHTSA has a record of another 2018 Lincoln MKC 2.0L EcoBoost experiencing a dealer-confirmed coolant-intrusion failure consistent with Ford's published technical guidance. I am particularly concerned about whether this failure mode has safety implications and whether the population of potentially affected vehicles has been adequately identified. The vehicle had not exhibited significant drivability problems, rough cold starts, or other obvious warning symptoms before the recurring P0303 check-engine indication.

This article supersedes TSB 24-2165 to update the TSB Service Procedure. Some vehicles listed in the Model statement above may exhibit various SYNC performance related concerns including but not limited to:  Display operation concerns  Navigation inoperative  Voice recognition concerns  Phone connection issues  Dropped phone connections  Applink related performance  Travel Link not present or showing incorrect traffic  Slow system response NOTE: Ford has found some of the APIMs replaced and returned for inspection contained an outdated software level and the APIM did not require replacement. The customer concern may have been resolved by updating the APIM with latest level of software. The SYNC 3 universal thumb drive will be able to update the APIM software without the use of a scan tool and does not require the process to be monitored. Ford will be monitoring APIM replacements to confirm TSB directed software updates have been performed.
