general problems of the 2017 Lincoln MKC - part 1

The contact owns a 2017 Lincoln Mkc. The contact stated that while driving at an undisclosed speed, the vehicle sputtered with a misfire coming from the engine, with the check engine warning light flashing on the instrument panel. The vehicle was taken to the dealer where it was diagnosed with coolant intrusion in cylinder #3, which caused the engine failure. The contact was informed that the engine needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure. The approximate failure mileage was 111,000.

Related to previous recall [xxx] I had the recall repair done. But my car with only 86,744 miles now has coolant in cylinder 3 and it's misfiring so badly the car shouldn't/can't be driven. Dealership says the entire engine needs to be replaced. I have never had a car this low of mileage that an entire engine needed replacement. This is a design flaw in the 2. 0 ecoboost and I now have a probably $20,000 or whatever it may have been worth when it ran. . . Paperweight. It's just sputtering and spitting out loads of smoke as described in original TSB. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

The 2017 Lincoln Mkc requires a full engine replacement due to a serious, well-documented defect: coolant intrusion. This is a major issue that can destroy critical engine components, including the head gasket, cylinders, and even the engine block. Ford/Lincoln is aware of this problem. They issued multiple tsbs (22-2133 and 22-2229, to name a few), yet customers are not informed. Because there is no recall, if the car is out of warranty, dealers refuse to perform the necessary repairs unless the customer pays tens of thousands of dollars for something that is a known manufacturing defect, leaving them vulnerable to catastrophic engine failure and potential accidents, injuries or worse. This is a known manufacturing defect, and consumers should not bear responsibility for the resulting safety hazards. Ford/Lincoln must take immediate action and issue a recall before it leads to serious injuries or fatalities.

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

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

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.

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 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.

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.

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.

I own a 2017 Lincoln Mkc 2. 0l ecoboost that suffered a complete engine failure caused by coolant intrusion into the combustion chambers. The vehicle began to misfire, emit thick white smoke, lose power, and quickly became almost undriveable. Technical service bulletin (TSB) 19-2346 (June 2019), which describes coolant entering cylinders due to a flaw in the cylinder head/block design. This failure is not the result of neglect or normal wear and tear — my vehicle has been maintained according to manufacturer recommendations. Despite this, the engine requires complete replacement at a cost of approximately $9,500. The failure occurred well before what should be the normal service life of an engine, and it matches the same defect pattern reported by many other Lincoln and Ford owners with the 2. 0l ecoboost engine in multiple model years. The coolant intrusion defect creates a serious safety hazard because it can cause sudden, unpredictable loss of engine power while driving. If the defect manifests at highway speeds, the driver may experience immediate power loss, inability to accelerate, or complete engine shutdown — increasing the risk of a collision. Ford/Lincoln have issued internal bulletins to dealers acknowledging this problem but have not initiated a public recall. Many owners have been denied coverage due to warranty expiration, despite this being a manufacturing defect. The result is that numerous vehicles with a dangerous and well-documented engine flaw remain in circulation without corrective action. I believe this defect warrants investigation as it poses both a safety risk to drivers and passengers, and a broader consumer protection concern. Premature catastrophic engine failures on relatively low-mileage vehicles undermine public trust and place owners in severe financial hardship. An NHTSA investigation could compel Ford/Lincoln to issue a recall to address this hazard before more vehicles experience unsafe sudden failure.

Engine light came on. Took it to mechanic. Was told there is a well documented mechanical issue affecting my 2017 , Mkc. My vehicle is experiencing a misfire and cylinder three accompanied by signs of colon intrusion into the engine, as well as transmission slippage. I have heard these are known and widespread issues in 2015 to 2019 Lincoln Mkc models equipped with the 2. 0l eco boost engine. I am aware of several technical service bulletins, including TSB 19-2346 and tbs 22-2229, that detail this defect. Numerous lincon customers have reported identical issues at similar mileage, often requiring full engine or transmission replacement. My trusted mechanic has verified that my vehicle exhibit symptoms consistent with this engine defect.

I was told by my Lincoln dealer that I need to replace the engine on my 2017 Mkc. This is due to coolant intrusion issue that seems to be a very common problem with this model. I'm really disappointed, it's a very costly repair ($10,000 +) I only had 85,000 on the car. I was driving on a highway and the car completely shut down. They said the only repair is an engine replacement and are not willing to assist in the costs. The check engine light came on when the engine seized.

The contact owns a 2017 Lincoln Mkc. The contact stated that upon starting the vehicle, the check engine warning light illuminated. The vehicle was taken to a local dealer where the vehicle was diagnosed, and the contact was informed that the engine was faulty and needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure. The approximate failure mileage was 70,000.

My 2017 Lincoln Mkc has engine coolant leaking in to the #4 cylinder. On start-up the engine runs rough, and the check engine light is on. Lincoln/Ford has a technical service bulletin #22-2229 covering this issue. I believe this is a common problem involving a large number of these engines. Licoln/Ford will not pay for any replacement costs. I have spent $1414. 08 in an attempt to repair this problem. I believe this also causes my car not to be able to pass the ohio e-check.

I purchased a 2017 Lincoln Mkc approximately 90 days ago and recently encountered a check engine light notification with the diagnostic code p303, indicating a misfire in cylinder three. After replacing the fuel injector on that cylinder and completing a tune-up, which included the replacement of all spark plugs and ignition coils, I consulted a new mechanic. They informed me of a potential issue related to engine block intrusion, which reportedly affected other 2. 0 l engines from Ford motor company within the 2015-2019 model years. As a result, I have been advised to consider replacing the entire engine. Given that I acquired the vehicle as a used model with only 43,000 miles and is now out of warranty, I am facing an out-of-pocket expense of nearly $8,000.

Symptoms consistent with TSB 19-2346 for 2. 0l ecoboost engines: coolant in cylinders, white exhaust smoke and check engine light is on. I have to keep topping off the coolant weekly, engine light comes and goes with same errors. Went to a general mechanic who got error codes po301-00 and po316-00. Currently scheduled next week to see an engine mechanic. Available for inspection upon request. Has not put us in danger yet but is of major concern due to potential for failure, so we are having it seen to ASAP. We don't have a Ford dealership so nearby to go out there with a failing car just to have them verify that yes that is the issue and yes it will be a very expensive repair we could not afford if we did it with them. Despite very low mileage it is still past warranty date, so any goodwill would have to come after we go through the trouble of bringing our vehicle in and hoping for the best. We called and they couldn't even provide any kind of ballpark likelyhood of goodwill.

The contact owns a 2017 Lincoln Mkc. The contact stated that upon starting the vehicle, the vehicle was shuddering. The contact stated while driving approximately 30-35 mph, the message "engine overheating" was displayed. The vehicle was taken to an independent mechanic, where the contact was informed that the coolant reservoir was empty. The mechanic added coolant to the vehicle and referred the contact to the dealer for assistance. The vehicle was taken to the dealer, where it was diagnosed that there was coolant intrusion in the engine block. The dealer determined that the engine needed to be replaced. The vehicle was not repaired due to the cost. The manufacturer was not notified of the failure. The failure mileage was approximately 89,800.

The contact owns a 2017 Lincoln Mkc. The contact stated that the check engine warning light was illuminated. The vehicle was taken to a dealer who diagnosed that the #2 and #3 spark plugs needed to be replaced. The vehicle was repaired; however, two days after the repair, the check engine warning light illuminated again, and the engine started to overheat. The contact checked to coolant level and discovered there was no coolant in the coolant reservoir. The vehicle was taken to a certified mechanic and was inspected, and it was determined that the failure was best diagnosed by the dealer. The vehicle was towed to the dealer and the contact was informed that the vehicle needed additional diagnosis for coolant intrusion to determine if the engine needed to be replaced. The vehicle was not repaired. The manufacturer was not informed of the failure. The failure mileage was approximately 70,000.

See attached document for complaint.

I took my vehicle to rainbow muffler and brake due to my engine light on. I was told I had an evap leak and it may just be my gas cap. I don’t have a gas cap. They turned the light off and it stayed off for a while. A few months later I took it in and was told to do a smoke test. Smoke test showed I need a purge valve ($214 for part from dealer) and rainbow charged $105 to install. A few weeks later light returns, I take it back to rainbow. I’m told a tune up $$250. A few weeks later light comes back on. I’m told I needed coils $325. A few weeks later light is back on. I immediately called rainbow to be told, Lincoln knows there a defect but they aren’t acknowledging it. I filed a complaint with the bbb and my states attorney general office.

Within 4 months, I’ve spent $12k on transmission replacement (refurb. ) (metallics in the fluid), fuel injectors, etc. The check engine light is still on…now im told that coolant is leaking into my engine, and the engine needs replaced! (coolant intrusion) another $9k for parts and labor! I just paid the car off! ive kept up with repairs and service! ive done everything the dealer has suggested…except replace the engine! I’m still recovering from the cost of the transmission! the 2017 Lincoln Mkc with a 2. 0l ecoboost engine has a known defect where coolant leaks into the engine cylinders, often causing misfires, overheating, or engine failure. This issue, linked to faulty engine block and cylinder head design, typically requires engine replacement ($5,000-$9,500). Ford issued TSB 22-2229 but no recall. A class-action lawsuit is ongoing. Check warranty status; report to NHTSA.

The contact owns a 2017 Lincoln Mkc. The contact stated that while driving at an undisclosed speed on a road trip, the engine coolant temperature warning light illuminated, and the engine overheated. The contact was able to continue driving to the destination. The contact stated that the transmission and rear brakes and rotors had previously been replaced. The vehicle was taken to the dealer, where the engine was replaced. The manufacturer was made aware of the failure and advised the contact to file a complaint with the NHTSA hotline. The failure mileage was approximately 99,800.

Coolant leak intrusion misfire cyl4 and cyl3 smoke vehicle shut down extreme engine shaking and fire check engile lights class action lawsuits manufacturers refusing to help and dealership is refusing to help. Dealership admits vehicle is unrepairable and has held possession for 75 days.

Known issue with the 2. 4l turbo engine and coolant leak resulting in need for engine replacement.

Bought this 2017 Lincoln Mkc with 75k miles on 2/21/25. Four days later while driving to work an engine light came on. Continuing on to work the car started running poorly while crossing a rail road track. Seemed like it was gonna quit running right there on the track. Then it started running like it did before except now there is a wrench starting blinking on my instrument panel. Had the engine code checked at o’riley’s and was informed it was number 3 cylinder misfiring as they recommend a new spark plug and coil. While they checked the code I called the dealer where I purchased the vehicle and I have an appointment scheduled for 10 am tomorrow. I’m sure they will install a new plug and coil and send me on my way knowing my warranty will be ending in a few more hundred miles . I’ve researched the issue and know the motor needs changed and it should be Ford to recall them. I’m handicap now and won’t be able to afford to fix it or buy another vehicle. This isn’t right and does needs to step up to the plate and accept responsibility for their mistake.

Torque converter failure that has plagued other Ford vehicles of this era having the 2 liter 4 cylinder engines. Please see attached letters to and from Ford and all work orders.

The engine in my 2017 Lincoln Mkc (2. 0l ecoboost) has a documented manufacturing defect where the cylinder block design allows coolant to leak into the combustion chambers. This has caused persistent, unexplained coolant loss and rough engine performance on cold starts since February 2025, matching the diagnostic criteria in Ford TSB 19-2346. The defective engine assembly is available for inspection. This condition creates a significant safety hazard, including sudden power loss (limp mode) in traffic and a risk of engine fire from cracked cylinder heads. While Ford provided a service program (21n12) for 1. 5l engines, they have failed to issue a safety recall for the 2. 0l variant despite identical failure modes. This vehicle is part of the class in the consolidated litigation miller, et al. V. Ford motor company (case no. 2:20-cv-01796). I am filing this to assist NHTSA in determining the necessity of a mandatory safety recall.

Check engine light on and after scan, code p0302 results. Engine feels sluggish. "coolant level low" displayed on dash, also temperature level rose to high so stopped driving it. Engine temperature elevated may catch fire car. Problem is coolant entering cylinder. Confirmed by two independent mechanics, and today by Lincoln mechanic. Vehicle is at Lincoln service center. Check engine light appeared on dash a few days before the temperature elevation and coolant loss. Got code p0302 a few days before the coolant loss and temperature rise.

The contact owns a 2017 Lincoln Mkc. The contact stated that the check engine warning light was illuminated. The vehicle was taken to o’reilly auto parts and was diagnosed with a misfire in cylinder #2. The vehicle was then taken to the dealer, where it was diagnosed with a misfire in cylinder #3. The dealer replaced the ignition coils and the spark plugs; however, the failure persisted. The vehicle was taken to an independent mechanic; however, no cause for the failure was found. Additionally, the contact stated that the vehicle was experiencing excessive coolant consumption, and the contact noticed an abnormal odor coming from the vehicle. The vehicle was not repaired. The manufacturer was notified of the failure and informed the contact that assistance would not be provided because the vehicle was not covered under warranty. The failure mileage was approximately 190,500.

The engine failure in my 2017 Lincoln Mkc was caused by coolant intrusion, a known design flaw affecting thousands of 2015-2019 models. This serious issue presents a severe safety risk to drivers and passengers. Symptoms engine light illumination shakiness and sputtering at startup misfire on cylinder #3 rapid coolant loss intermittent engine light warnings battery-like symptoms (vehicle not starting, clicking sounds) violent shaking during 1 startup diagnosis and repair attempts replaced component for cylinder #3 misfire installed new spark plugs refilled coolant reservoir battery checked and jumped final diagnosis: engine replacement required due to coolant intrusion issue confirmed as a known design flaw in Lincoln Mkc safety risks the coolant intrusion problem poses significant safety risks: potential for sudden engine failure while driving, especially at high speeds risk of losing control of the vehicle due to engine seizure danger to occupants and other road users in case of unexpected breakdown confirmation and inspection the issue was reproduced and confirmed by both monro auto and the Lincoln dealership. The vehicle was inspected by the Lincoln dealership, which determined the need for a complete engine replacement the warranty company approved the engine replacement, acknowledging the severity of the problem warning signs intermittent check engine light illumination occasional shaking and sputtering at startup rapid coolant loss without visible leaks intermittent starting issues resembling battery problems one episode of violent shaking at startup all of these symptoms appeared sporadically manufacturer responsibility despite being aware of this design flaw and even developing a new engine to address the issue, Lincoln has not issued a recall. This lack of action raises serious concerns about the manufacturer's commitment to customer safety. The problem is widespread, as evidenced by numerous reports on Lincoln Mkc forums, indicating a systemic iss.

I have a recurring coolant intrusion problem. Available for inspection. Risk of engine seizing up and running hot. The problem has been identified by a licensed mechanic. The vehicle component has not been inspected by manufactured however this is a known issue by Ford. Check engine light, misfire of cylinder #4 (p0304) and coolant inside cylinder.

Engine design flaw in the gaskets. Coolant leaking into the cylinders causing misfire. Had to replace the engine. $8000.
