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…

My engine failed. At the time I did not know this. I was driving to work, and although I knew I was not out of gas according to the gas gauge, I thought maybe something was wrong with the gauge when my Lincoln began to putter like when you are running out of gas. I was approaching a stop light in the left turn lane when the car died. Which could have caused a multi car pileup considering the intersection in my town I was at. I got the car to start again but it smelt terrible and started smoking from the exhaust. A white smoke. I was not far from work at all so I made it there and had a mobile mechanic come to look at it. Upon inspecting it, he found oil build up in my spark plugs. When he…
