Incident

Jun 28, 2026

My 2016 Lincoln MKC with a 2.0L EcoBoost engine experienced coolant intrusion into cylinder 3, leading to engine misfire and check engine light to turn on. The dealership confirmed the issue for $176.55 and recommended a full long block engine replacement, estimated at over $11,000. This failure occurred at 98,000 miles. Two weeks before this, the check engine light illuminated and we took it to a repair shop where we paid $628 to repair the purge valve and fuel pressure sensor, while it was most likely this coolant intrusion both times! Ford and Lincoln (including concierge) have refused any assistance in this matter. The local dealership has also said that they cannot help us with any of the cost. I've found this to be a very well documented problem/engine design failure, Including HTSA ID Number: 10162062 Manufacturer Communication Number: TSB 19-2172 entitled Components: ENGINE AND ENGINE COOLING The TSB acknowledges a design-related coolant leak into the engine cylinders that can cause white smoke, misfire, rough running, and warning lights. Ford’s recommended repair is to replace the long block assembly. In addition, this appears to be the exact issue described in Ford TSB 19-2346, which covers 2017–2019 model year vehicles with the 2.0L EcoBoost engine, including the Lincoln MKC and MKZ. I believe this is a widespread design defect and request NHTSA’s investigation to ensure proper manufacturer accountability. I am so thankful that this car does not belong to one of my daughters as it poses a severe safety hazard on the road and it is going to be a huge financial setback that we may not recover from.

At 85,000 miles I was experiencing a grinding noise coming from my front end when making sharp turns to left or right. Took car to my mechanic immediately for diagnosis. They found the motor mounts and rear differential is binding and close to failure. My mechanic contacted FOMOCO to see about a replacement for the rear differential and was told that there were not any available due to a REDESIGN of the product. He was asked to check back in two weeks! Two weeks w/o my transportation! I replaced the motor mounts, (85Kmi?) After researching on line, several ford & lincoln sites the problems I am experiencing are not unique or infrequent on Lincolns and ford Edges. It would seem to me that these problems are frequent enough to have the manufacturer ininitiate a recall on these products! My mechanic also works on our Sherriff department vehicles and their Ford Edge units are experiencing same problems. I would hope these problems will initiate an investigation into this matter!

While driving a short distance to work, my 2016 MKC check engine light came on. The previous week I noticed that the engine hesitated slightly when it first started, but it drove normally. However, when the light came on, my husband took the vehicle to the dealership where we bought it in Dec 2019. We were shocked when we were told this was a very common problem with this type of engine, a 2.0 eco boost, and that the engine would have to be replaced due to coolant intrusion, at the cost of $9300! The vehicle only has 57,000 miles on it and has always been maintained at Prater Ford Lincoln in Calhoun GA. After some research I've found this to be a very well documented problem/engine design failure. Ford and Lincoln have refused any assistance in this matter. The local dealership where we purchased it has told us they won't provide any assistance either. The vehicle is currently in the shop, and the engine is being replaced. It was supposed to be completed 5 days ago. Why hasn't there been a recall? Even though there were no deaths or injuries in my case as well as the others on this site, the financial burden is immense! Since this is such a well-documented problem, there should be a recall on the affected engines, or at the very least some assistance should be provided by Ford and/or Lincoln to the unfortunate owners of these vehicles. Thank you.

I purchased a 2016 Lincoln MKC 2.0 with 96k miles on it 2 months ago, and we just discovered a coolant leak into the first cylinder, causing a cracked head gasket. The engine needs to be replaced, and will cost $15k. Many other drivers have experienced this problem and reported it, and Ford has done nothing to correct the main issue. This problem is causing overheating of the engine, and could potentially cause injury if not fixed.

We purchased the vehicle about a year and a half ago and about three months after we purchased it. The check engine light went on. We’ve had the vehicle into the dealership several times we’ve had the problem fixed supposedly twice we put in over $1000 in fixing it and now the check engine light came on again And the car stopped running saying it’s overheating. Took it to the dealership and now they say the car needs a whole new engine because they antifreeze is leaking leaked into the engine so they’re quoting us a $12,000 repair. This is a common problem in later models but obviously in the 2016 it’s also a problem.

While driving at various speeds, the vehicle hesitated upon depression of the accelerator pedal, with the check engine warning light illuminated. In addition, the contact stated that the engine was consuming an excessive amount of coolant, and there were no signs of a coolant leak. The vehicle was taken to an independent mechanic where the turbos, spark plugs, and fuel injectors were replaced; however, the failure persisted after the repair. The contact then scheduled an appointment with a local dealer for a diagnostic test. The vehicle was not repaired. The manufacturer was notified of the failure but offered no assistance.

Purchased 2016 Lincoln MKC from a Ford dealer in October with approximately 133k miles. Was a trade-in from August. The beginning of January on a very cold day while warming the MKC, the air stayed cold. Drove to work and back. That night added antifreeze as it was low. Next day on the way to work, shortly after leaving home the MKC started losing power and shaking. Couldn't pinpoint where the shake was coming from. A friend's husband is a master tech at the Ford dealership where I purchased it. I described the issues to him. He looked under hood. The antifreeze that was filled up the day before was completely empty. He could tell what the issue was. I called the dealership. Was initially told it would cost $10k-$12k to replace engine. Talked to several managers at the dealership. Called Lincoln Concierge. There was no recall for my vin. The design of my long block with the 2.0 Ecoboost was the same design as the vehicles recalled in 2017-2019. After a second call to Lincoln concierge, was told the vin specifics are based on the plants where the vehicles are made. I did get the MKC to the Ford dealership to do an official diagnosis and it was confirmed that there was coolant intrusion. This has been very disheartening. I'm not understanding why, if the engine is the same design flaw, there is no recall or assistance.

My 2016 Lincoln MKC has a recall. Recall was mailed to me and I called closest Lincoln dealership to begin process. Dealership stated part was on back order and I would get a call when it comes in. I called a few weeks later and still no luck. I attempted calling several times with no luck. Fast forward 2-3 months after calling, I’m driving with my son and out of nowhere the car begins to stall while driving and fumes start coming out from air vents. It was an awful and strong smell. As I pulled over the check engine and battery light came on. I had vehicle towed to dealership which they return with a catalytic converter code. I paid to get replaced and get a call that car is good to go, but recall part is still not available. Picked up my vehicle and didn’t make it more than .5 miles I realized my car is stalling and will not go past 40mph. Take it back, employees look dumbfounded and ask me to leave car and they will get back to me. I get a call a week later stating I need a pigtail connector and all will be fixed. They change it out, I go pick up my car and still same condition. Leave dealership and wait on another call stating it is a whole electrical wire harness which needs to be changed. I am Told last week that it would be $1900 to repair! I still do not have my car back and feel as if it is a guessing game at my expense!

A gasket failed which allowed coolant to leak into the engine. Due to lack of coolant, two of the cylinder heads cracked and warping of the engine block occurred. No coolant in the engine could result in a engine seizure or fire which poses an extreme risk to one's safety. The check engine light came almost immediately before the cylinders started to misfire. 11/25/2023. The vehicle and components have been inspected by the dealers service department and the warranty inspector. The car needs a full engine replacement which only half is covered under the warranty. I am out of pocket the other half. See link regarding a current lawsuit the describes EXACTLY what happened to my vehicle: [XXX] .
