I was driving home from work on December 24th 2025 and my 2018 lincoln mkc 2.3l shut off on me while I was in motion. There were several cars that had to swerve and not hit me. The car would not start but I was able to put the vehicle in neutral and roll to the shoulder of the road. I was very scared and angry because this vehicle only has 54,646 miles currently, give or take 50 miles. I had to get the towed to my home. This needs to be resolved and Fird/Lincoln needs to faithfully fix this dangerous defect, i could have died. Please please do something because I do not want anyone else to deal with this.

The check engine light came on and it would run rough when started. It was determined the number four cylinder head was cracked, allowing antifreeze to leak into the engine block.

There had been a recall on later models, but no recall for the 2018. I believe it should be under recall.

Coolant is leaking into the cylinders and could cause the engine to seize while driving. The issue was identified at a Ford dealership and is a known issue on this engine and has been admitted by Ford/Lincoln as a problem. The only warning was a check engine light which appeared after the problem existed and only fix is to replace the engine. Ford/Lincoln did not make any attempts to notify owners in advance of this issue so it could be checked. There are still many of these engines on the road which could seize at any time and cause tragic results.

I have a 2018 Lincoln MKC with the well known coolant intrusion complete engine failure. I need a new long block at a cost of 9500 dollars. I had no warning light or check engine light to warn me about this issue prior to taking it to Ford dealer in Buellton to ask why coolant was emptying so fast. I had previously taken it to Lincoln dealer while under warranty and was told no issues. Even though they had a specific service bulletin stating the problems I was having. I feel my safety was at risk because I drive alone into sketchy areas for my job and my car could have just stopped and I would be an elderly woman alone with a broken down car waiting for a tow. It also could have possibly caught on fire I’m told. Lincoln Concierge was no help. Said it was VIN specific and not enough vehicles affected to warrant a recall. Mechanic at Ford says 3 to 4 vehicles a month are being repaired at his shop and they are a rural dealership. I think we are all being fleeced. We spent 40000 plus for a luxury reliable vehicle. We still have car payments. Can’t use as trade in. Can’t afford to buy another car. I can’t do my job. The stress alone may be dangerous for my health. Pending lawsuit won’t begin until June of 2026. This is so wrong
