2019 Lincoln Mkc with 96k mileage suddenly started running rough around 30mph and I was losing power as I was entering a highway on a ramp. Rpm needle was fluctuating between 2k and 3k. Immediately drove back home and towed it to Lincoln shop. They said its an issue with coolant intrusion into the engine compartment and would have to replace the engine block. Estimated at $11k. Extended warranty company said claim is likely to be denied as these ecoboost 2. 0l engines are notorious for these issues. It is a faulty manufacturing and there is no recall. Costing consumers thousands of dollars and also putting lives of passengers at risk.

My initial reason I took the car to the dealership, was because the vehicle would not want to start or stay running after fuel was put in. I aiso had a check engine light on. After the dealership performed diagnostics on it, they said the purge valve was bad which was the cause of it not starting. The check engine light was on because it was low on coolant. So I scheduled another appointment with wyatt Ford in manistee mi 49660 on Dec 1, 2025. They performed a coolant pressure test and determined that it is losing pressure after shutdown. They cannot find a leak. They removed the spark plugs, but #3 spark plug is "stuck" and they are attempting to remove it. If the spark plug breaks, they will take more of the engine apart to access it and attempt to "tap" out the threads of it. The technician (sherman) told me that the cause of it being stuck could be due to the fact of the coolant leaking into that cylinder. Sherman was able to remove the #3 spark plug and found coolant in that #3 cylinder. They are now saying that the engine does need replaced and it is not safe to drive. The service department (ava) gave me Ford customer service number to call to start a case. I called 800-392-3673 and spoke with alex. She told me she will do some further research and call me back in about two hours. It is now 12:30 pm east coast time. After returning a call from her, she said that there are no programs at this time with Ford to assist with replacing the engine. Only if there is a recall on this is when they would be able to replace it for us.

Engine failure due to known coolant intrusion defect documented under Ford ecoboost TSB guidance. Denied goodwill assistance despite defect being manufacturing-related.

Lincoln 2019 Mkc reserve head gasket problem check engine light on. Took to dealership and confirmed with compression test that it was TSB – 22–2229 had to replace engine with new long block. Lincoln corporate assistance paid some 2835. 10 I paid $4265. 05.

My car misfired, then the heat wouldn't work then started to overheat. The car is 2019 Mkc 2. 0l engine. Only 64k miles on it. I am the original owner. Took it to the dealership and they said the coolant has back up into the engine. I read that this has been a known issue with these engines and was never notified. It is going to cost 10k to replace this engine.

The 2019 Lincoln Mkc model made prior to April 2019 is part of a variety of Ford/Lincoln manufactured models that are known to have a coolant intrusion issue. This causes various issues within the engine system such as head gasket failure, cracked cylinders, and cracked engine block causing the coolant to leak and potential for fire risk. Although check engine light warning will be present, the code is presented as a misfire and the suggested fix is to replace spark plugs and coils. This will be completed, and seem to resolve this issue however, it is temporary and problems continue to persist. The car will loose power while driving and be unable to accelerate or continue to keep consistent speed such as when driving on freeway. Despite having a TSB 22-2133, customers are not made publicly aware of this issue and if they do not fit within warranty timeframe the dealer will not complete recommended service of the issue. Therefore, the customer is not at fault for the unsafe, known manufacturing issue and therefore Ford/Lincoln should make the effort in correcting this prior to serious customer injury/death.

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. I bought the car new in January 2019. The problem appeared with under 57,000 actual miles. The car has always been serviced on time at the dealership. The cost to fix the problem with a new engine is approximately $10,000. I bought the car new so that I would not have problems. It is my only form of transportation. In researching, I have found this is a reoccurring problem on the echo boost four-cylinder engine since 2017. It didn’t matter whether it was low mileage or high mileage the cracks would appear. There had been a recall on later models, but no recall for the 2018. I believe it should be under recall.

Engine seizes while driving and chokes due to engine misfire. First occurence was at 34kmiles in 9/2023 and when brought for emissions check mechanic said needed new spark plugs/coil so had them replaced for $800. 3-4months later after only 1k miles check engine light goes on again and car hums/rattles like it will stall. My brother runs diagnosis and same issue and that’s when I started to do research and found that Lincoln Mkc 2019 have known engine issues. As it was under warranty until Dec 2024, I brought to steven’s Ford in milford CT and raised this engine issue and specifically asked for full repair to ensure issue is fixed. 18 months later on 11/12/2025, while driving car the engine starts to hum and rattle feel like it will seize and check engine light goes on again. Same issue from when I had repair under warranty but Lincoln dealer claims it’s a parts issue and not an engine issue. These vehicles are dangerous and can cause accident due to engine just stopping. Dealership and Lincoln refuse to provide any support.

The contact owns a 2019 Lincoln Mkc. The contact stated that while driving at an undisclosed speed, the temperature gauge started to indicate that the engine was overheating, prompting the contact to discontinue driving the vehicle. The check engine warning light was illuminated. The vehicle was taken to an independent mechanic, who determined that there was a misfire in cylinders #2 and #3. The contact was informed that the spark plugs needed to be replaced. The vehicle was repaired, but the failure reoccurred. The vehicle was not repaired. After investigating the failure, the contact related the failure to the customer satisfaction program: 21n12. The manufacturer was notified of the failure, a case was opened, and the contact was referred to the NHTSA hotline for assistance. The failure mileage was 58,555.

Head gasket leaked coolant into the engine and now the engine is not working and needs replaced.

Coolant intrusion in engine.

Total engine failure due to coolant leak into the 2. 3l Ford motor. This is a known issue with the Ford motors and it is not covered. This eventual coolant leak makes the owner have to buy and replace the engine with one that has similar issues and costs $8300+. This is unacceptable and Ford needs to cover and address. Never had an engine do this to me before and it’s horrible. Please hold Ford accountable. Navy ad and with the shit down, this will be an expense I can not cover with 3 children, one in college. Was planning on keeping this car till the filter falls off… not anymore I guess.

My Lincoln Mkc 2017 is having a recurring problem with a misfire in the 3rd cylinder due to a hood gasket, a crack in the coolant, and leaking on the sparks and coils. I have had my mechanic work on and look at it, and it is a manufacturing defect. When I called, there was no recall listed for my vehicle except the backup camera. However, when you look at kelly blue book, it says there is more than one engine recall and issue, which is exactly what is happening to my Lincoln. The engine block heater may crack and develop a coolant leak, causing it to short circuit when the block heater is plugged in.

Car had engine light come on, was told from dealer need completely new engine despite only 70k miles. Is a known issue, please protect us consumers.

The contact owns a 2017 Lincoln Mkc. The contact stated that upon starting the vehicle, the check engine warning light illuminated on the instrument panel, followed by a coolant temperature message. The vehicle was taken to a dealer, where it was diagnosed with a hairline crack in the engine. The hairline fracture led to coolant intrusion inside cylinder #2, and the vehicle was diagnosed with engine failure. Upon investigation, the contact discovered technical service bulletins 19-2346 and 22-22229, which the contact linked to the failure. The contact called another dealer about the failure and was informed that there were no recalls on the vehicle related to the failure. The vehicle was not repaired. The manufacturer was notified of the failure but offered no assistance. The failure mileage was 98,690.

The vehicle was taken to the dealer where it was diagnosed with engine failure. The contact was informed that the failure was due to coolant intrusion into the engine. The contact was informed that the engine needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure but provided no assistance. In addition, the contact referenced NHTSA campaign number: 25v685000 (equipment); however, the VIN was not included in the recall. The failure mileage was approximately 42,000.

The engine light came on. It was inspected and there is a coolant intrusion. Apparently, this was a known issue for this engine. There is an existing technical service bulletin (TSB) 22-2229 and a Ford customer satisfaction program (csp) 21n12 related to this issue the program indicates up to 7 years or 84k miles, which I believe this falls under (my mileage is 42k) providing a one-time repair program providing a no-cost short block replacement.  Ford is not cooperating.

Check engine light came on. The engine has coolant intrusion and the engine would have to be replaced, quoted me $17,240. 83 I called 888-214-2155 Lincoln client relationship center and I was told there was nothing they can do to help me. After doing some research, this has been a known problem by Lincoln and they have not put out any recalls. They also have a class action lawsuit against them.

I got out of work and went to start my car. At first it did not want to start, and it acted like the alarm system had an issue. I locked my car, then unlocked it with the key fob, and when it started, it ran rough and was smoking out of the exhaust. I turned it off and quickly checked the fluids. I noticed the antifreeze was low, and since I always carry fluids in the car, I filled up the reservoir and then tried to restart my car. It did the same thing, not wanting to start until I locked and unlocked with the key fob. I drove home, but the check engine light was on the entire time. The following morning, I started my car and it was blowing white smoke out of the exhaust. I turned it off and contacted a local auto repair shop. It had to be towed to the shop so as to not cause damage. The auto shop said it was the head gaskets and since there was a known problem with the coolant leaking, I would have to get a whole new (used) engine. The total would be over $8000. I called another repair shop to see if they would be willing to replace the head gaskets, and after they agreed, I had it towed to their shop. After diagnostics, (no negligence on my part) this shop also refused to just replace the gasket citing an ongoing class action lawsuit due to a known head failure, and the repair with a new engine would be over $9000. I had purchased an extended warranty (power train) when I purchased this vehicle, and it included seals and gaskets. . . So I thought I was covered for this problem. The warranty company refused to cover it since it was a head problem. I still have 2 years of payments left on this vehicle.

The contact owns a 2017 Lincoln Mkc. The contact stated that while driving at an undisclosed speed, the vehicle jerked. No warning lights were illuminated. The vehicle was taken to a transmission specialty shop and was diagnosed with torque converter failure, which caused transmission failure. The torque converter was replaced. The contact stated that on a separate occasion, days after the vehicle was repaired, the check engine warning light illuminated. The contact pulled into a gas station and turned off the vehicle. The vehicle was towed to the dealer, where it was diagnosed with coolant intrusion into the engine, which caused the cylinder head to crack, causing engine failure. The contact was informed that the engine needed to be replaced. The vehicle remained at the dealer unrepaired. The manufacturer was not contacted. The failure mileage was approximately 112,000.

After a repair/service visit at a national auto repair chain, my 2017 Lincoln Mkc developed ongoing severe drivability and safety issues. The check engine light began flashing (active misfire), and the vehicle was unsafe for highway travel due to risk of loss of power/engine damage. Independent shop documentation reports cylinder #4 misfire (p0304) and additional engine timing-related code(s), low oil condition, and notes indicating internal engine damage and that the engine may require replacement. The vehicle also had a vacuum/brake booster line issue that affected brake assist until corrected. The problem has been confirmed by independent service centers and the vehicle is available for inspection. There was a near crash, but no fire, injury, or police report occurred.

A few months ago, the engine light came on. Multiple diagnostics confirmed a vapor leak. We were told if we didn’t fix it, it would affect nothing. Now, if we put gas in, the car struggles to start or won’t start. This happens all the time since April 2025. We looked at recalls and there were 2 with the fuel system that were apparently done. We feel that they may have been improperly repaired? the dealer service said this problem happens all the time with Lincolns. We’re afraid to put gas in the tank. We don’t know what will happen next? car stopping at lights? too much vapor coming out now? repair is all over the place price wise wherever we check…but we don’t want to be stuck at a gas station or have someone light a cigarette near the car with gas vapor leaking out!.

I am writing regarding my 2018 Lincoln Mkc, VIN # [xxx] which is experiencing clear symptoms of coolant intrusion into the cylinders. These include low coolant levels, white exhaust smoke, engine misfires, and a rough-running condition. According to **technical service bulletin 19?2346** (NHTSA id 10169807, dated December 20, 2019), this issue is a known defect affecting Mkc models with the 2. 0l ecoboost engine and recommends replacement of the long?block assembly to correct the problem. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

Coolant leak, no warning overheating car turned off,needs new engine,coolant leak into cylinder ,only 62000 miles on the car.

The contact owns a 2017 Lincoln Mkc. The contact received notification of NHTSA campaign number: 23v378000 (engine) and 25v572000 (back over prevention). However, the parts to do the recall repair were not yet available. The contact stated that while the vehicle started, the interior lights and lights on the instrument panel failed to function as intended. No warning lights were illuminated. The vehicle was taken to an independent mechanic who determined that the failure was due to an electrical system failure. The vehicle was repaired. The contact stated that the failure persisted. The vehicle was taken back to the independent mechanic; however, the independent mechanic referred the contact to the local dealer. The vehicle was not repaired. The contact stated that on a separate occasion, the rearview camera displayed a distorted image while the vehicle was in reverse(r). The contact stated that the failure obstructed the driver's visibility, which prevented the driver from safely operating the vehicle. The vehicle was not diagnosed or repaired by an independent mechanic or dealer. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was not made aware of the issue. The failure mileage was approximately 80,000.

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.

The engine light periodically came on. The coolant was low, but no evidence of a leak. We took the car into be evaluated and to was identified as error code p0304 for cylinder #4. The only way to repair is a new engine. The car has 71000 miles on it. During our research it was identified that this is a known issue to Ford, but this has not been acknowledged as a defect/recall. It was recommended to immediately repair as the engine can stop or the car can lose power /control while driving. The car is no longer under warranty. There are tons of reports of this issue, and 130 reported on this site. This is a danger to those driving or if something would happen on a highway, this could cause an accident at high speeds to the other cars trying to avoid a stopped car. Dealers recommend calling to complain to Ford to attempt to get resolution. And there is a class action lawsuit.

Coolant intrusion into the cylinder causing overheating. New engine block required. Car has been regularly maintained. Failure occured with no warning.

The contact owns a 2016 Lincoln Mkc. The contact stated that while starting the vehicle, the vehicle was shaking, and the check engine warning light was intermittently illuminated. The contact stated that her brother had replaced the spark plugs and ignition coils. The vehicle was taken to the dealer, who determined that there was coolant intrusion into the engine. The contact was informed that the spark plugs and coils needed to be replaced with oem parts, and the turbocharger, purge valve, vacuum line, long block, and fuel pressure sensor needed to be replaced. The contact stated that her nephew replaced the spark plugs and ignition coils with oem parts, and aamco replaced the fuel pressure sensor; however, the failure recurred. The vehicle was not repaired. The manufacturer was made aware of the failure and advised the contact to report the failure to the NHTSA hotline. The failure mileage was approximately 158,000.

The vehicle has now been at the dealership for almost two weeks. I drove the car in under its own power and was shocked to learn that it needs a new engine (long block) due to a known issue described in a technical service bulletin (TSB) 19-2346 after doing my own research, I discovered that this is a widespread problem with the Ford 2. 0l engine, and the dealership confirmed this by stating they’ve replaced hundreds due to this defect. I then contacted Ford directly, but was told by customer service that the vehicle is out of warranty, and nothing could be done. The Ford case number is [xxx]. Let me be clear: this is not normal wear and tear. A major engine failure at only 63,000 miles is completely unacceptable — especially in a certified pre-owned (cpo) vehicle, which I was sold as reliable transportation. I now realize that Ford and its dealers have been knowingly selling vehicles with a manufacturing defect, without taking responsibility when those vehicles inevitably fail. This is a documented defect in the engine block, as acknowledged by Ford in the TSB. Yet there is no recall. Why? this issue poses a serious safety risk, not to mention a massive financial burden for consumers who trusted Ford’s certification and quality standards. It is deeply concerning that Ford has chosen to avoid accountability, leaving owners like myself to pay for expensive repairs stemming from your own design flaw.

There’s a cracked block/head gasket causing coolant to leak into the cylinders and now my engine needs to be replaced.

Engin light came on, was diagenosed as coolent leaking in spark plug , or bad head gasket.

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.
