2017 LINCOLN MKC Engine Problems

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.

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.

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

COOLANT LEAKING INTO ENGINE, CAUSING MISFIRES AND ENGINE SERVICE LIGHT ON

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.

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.

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.

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

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.

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 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.

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.

The contact owns a 2017 Lincoln MKC. The contact stated while driving at an undisclosed speed, the check engine warning light and the #4 coil failure indicator warning light illuminated. The vehicle was taken to an independent mechanic and coil #2 was switched with coil #4; however, the failure reoccurred. The independent mechanic reset the codes however, the check engine warning light illuminated. The vehicle was not diagnosed or repaired by an independent mechanic or the dealer. The manufacturer was not made aware of the failure. The failure mileage was approximately 62,000.

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.

August of 2024 I took my vehicle to Island Street Automotive in Stoughton Mass because my engine light kept going off and off. The test showed the cylinder one misfire. They change the spark plugs and cylinder. However, I ended up taking the vehicle back 3 times for the same issue and experienced the same results. By now the check engine light was on all the time. I then realized a week or so later that the coolant was empty. For the next couple of weeks I continued replacing the coolant and had an auto shop look to see where the coolant could be going but they could not figure it out. There wasn't any leaking out of the vehicle. Soon my vehicle would begin shaking at the start up with the engine light blinking and then it would go solid. I decided to take the vehicle to Herb Chambers Lincoln of Norwood where I purchased the vehicle. They never mentioned that there was a bulletin out on this vehicle when I purchased it. It took them 3 days to diagnose. I was told the engine had to be replaced and needed a long block assembly. The charge would have been $8,634.31 plus tax. I called CarShield to put in the claim and they denied it because they found a bulletin out on the engine and stated it was a manufacturers error so they would not honor the claim. I called Lincoln directly and spoke about this issue but they blew me off and said there were no programs to help me pay for the cost of fixing the problem. I reluctantly chose to take the vehicle to North End Motors in Canton. They came up with the same conclusion. The engine was built with an open block and they needed to replace it with a closed block engine because the coolant was leaking into the oil. The charge was $7,494.72 plus tax, less than Herb Chambers. I chose to have the vehicle repaired with much anguish. I was not responsible for the issue with this vehicle but had to pay the astronomical cost. Thank you for reading.

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.

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.

Vacuum pump, 2.3 ecoturbo charger not available for inspection. Dealer in ND replaced vacuum pump twice and car ran worse than when I brought it in so they then decided it was the turbocharger and replaced it. My check engine light and ABS light were on. Could not drive over 55 mph and was on highway when lost power and slowed way down significantly with traffic congested. Had to pull off to side. Thick Smoking from tailpipe they said oil got lnto the catalytic convertor it would eventually wear off and ok to drive. Took to different dealer and they replaced the vacuum pump again (this was the 3rd one)it has 73000 miles on it. I Drove for 20000 without trouble. Now I'm at dealership in TN and they are replacing the entire engine. Without any help from Lincoln and the car has 91000 miles on it

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 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

The coolant intrusion into cylinder #2 . Very well known problem with Ford EcoBoost engines. This car has the 2.0L engine and there hasnt been a recall on it yet. It becomes a safety concern when the problem gets bad enough to allow oil to leak , causing a engine fire. The problem was diagnosed by a Lincoln dealer. No, it was not inspected by the manufacturer but my dealer did communicate the issue to Ford. There were check engine lights because this causes a cylinder misfire as the coolant leaking into the cylinders is burned. We already had the problem repaired by replacing the engine long block assembly which cost $8176.93 .

The contact owns a 2017 Lincoln MKC. The contact stated that while driving, a burning odor was detected as the vehicle lost power. Upon the contact's arrival at home, her fiancé called AAA service.

There is a huge problem with my vehicle it started leaking coolant into the cylinder. The vehicle is using coolant and burning it through the exhaust. This defect in the engine block causes catastrophic failure if occuring during driving on highway can cause accident and fire.

Lincoln/Ford knowingly designed an engine where the head gasket is unable to properly seal and overtime causes intrusion of coolant into the cyclinder causing overheating. This results in the need to replace the ENTIRE engine block. They are aware of the issue and continued to build these engines with the KNOWN safety issue from 2017 - 2020 on not only Lincolns but Fords. The dealerships are aware of the issues, the corporate companies are aware of the safety issues and still there is no recall on these. They wont even help pay for the new engine. My car only has 43,000 miles on it! I should not be replacing an engine already for this known safety issue. This should be recalled immediately. I was driving my young children 3 and 1 around when the coolant overheated and it could have or ceised as I am driving or caught on fire. Someone should not have to die in order for a recall to happen. Lincoln/Ford need to make this right before someone dies. They knew of this issue when they designed it and continued to make them until 2020.

Started with a rough start in the morning. Check engine went on and took to Advanced Auto to have code checks: P0302 1/3 Stored Cylinder 2 Misfire Detected DTC Severity 2 of 3. Repair immediately if drivability issues are present. Threat to essential. I immediately went to our Ford Dealer who has been maintaining our vehicle. First thing they did was open the hood and told me to keep an eye open for the antifreeze level. He then told me that they have problems from 2017-2019 with these 2.0L Ecoboost engines - Coolant, white exhaust smoke and/or Illuminated MIL. He stated that they do not fix this engine, and provided me a 13 page report and wrote and estimate for $6,500 + tax to have the engine replaced. I have 60,000 miles on my 2017 Lincoln MKC. I drive 14 miles to work and back 3 times a week. I baby this car. This engine should not need to be replaced after 60,000. I bought the car in 2020. On December 19, 2019, Ford has technical service bulletin #19-2346 and it appears that do not disclose this to avoid fixing under their 6 year or 70,000 mile warranty. This is really unacceptable on Ford's part. Shame on Ford for not creating a recall for this engine failure. We customers should not have to pay for a newly designed engine after Ford knew that this engine was a failure. I am demanding Ford to look into this engine problem. This is unacceptable!!! I am requesting for Ford to pay for my newly redesigned engine. Bill Ford has a statement on Ford Motor Company's website: We see no conflict between business goals and social and environmental needs. I believe the distinction between a good company and a great one is this: A good company delivers excellent products and services. A great one delivers excellent products and services and strives to make the world a better place.

I purchased 2017 Lincoln MKC new almost immediately had electrical issues with it that has stayed throughout the vehicles life. At about 55,000 miles my car started acting up like it was misfiring. I took it to Lincoln and twice they said they couldn’t feel anything. I left the car over night because it mainly happened in morning starting up and going a certain speed. Lincoln called me and said it was something with transmission and they would fix it. The problem did not get better. At approximately 70,000 miles my engine light came on and I took it to be read. It read cylinder 1 misfire. I changed out my plugs and coils and had light reset. Light came back on at 71,000 engine over heating. I added/filled engine coolant. Light came on off and it was chalked up to an electrical issue they couldn’t find. I have had to refill my coolant several times as it drains quick in sumner heat and I have had to change my plugs and coils again. My car was recently at a Lincoln and they noted my spark plug and coils on the floor. They asked me about the radiator fluid and I explained what has been happening to my car since 55,000 miles. I was told that Lincoln is well aware that this is a problem with the MKC with radiator fluid leaking causing it to leak into out plugs, cause misfire and eventually seize the engine but there has not been a recall, leaving buyers stuck. My issue is that I went to dealership with these problems but was ignored and told it was something else. Lincoln purposly blamed the issue on something else so my warranty would be done and they wouldn’t have to cover the cost. They knew about this issue and purposely pushed it off so they would not be responsible.

Car was misfiring, so I took the car to the dealership. There is coolant leaking into the engine cylinders and there is white exhaust smoke. They tell me that this is a known manufacturer defect. There is even a Technical Service Bulletin by ford recognizing the defect. TSB-19-2346. The repair requires the engine block to be replaced. Cost is over 6K.

Coolant leaks into the engine cause the engine to eventually breakdown and a whole new engine is needed.

Engine light came on.Noticed some hesitation. Took to the dealer. Was diagnosed as coolant intrusion into engine. Engine could have failed on the highway or exploded. After investigating & seeing other incidents like this on-line, I noticed there were fires & breakdowns that did occur. I called Ford/Lincoln to report. They are aware of issue, but would not cover the repair even though they have been aware of the issue for years. Bought my certified 2017 Lincoln MKC in 2020 with 25k miles with extended warranty; Currently has 68k miles. I had extended warranty thru Feb 2024, and was not aware it had expired. If my warranty was still current & had less than 70k miles, it would have been covered. I believe there should have been a recall on this type of engine. I believe that FORD/LINCOLN is responsible for the repair.

My engine kept misfiring upon starting and not accelerating while I was driving it. A coolant leak into the cylinder caused the engine to malfunction. I had to replace the entire engine block which cost over $7,000.00. The Ford repairman & service center told me that Ford had issued a service bulletin regarding this issue but then refused to pay for the engine damage. I only have 70K miles on the Lincoln.

2.0 Ecobooster engine. Coolant started leaking into engine right after an oil change at dealership. Now I need a new engine. I have researched that this is a known engine problem for Ford. We need a recall. I cannot afford a $9,000 repair for something Ford knew about.

My 2017 Lincoln mkc 2.0 . My mechanic confirmed it has a coolant leak going into the engine. There is a known defect with the 2.0 engine.Which is requiring me to have to purchase a brand new engine with only 33,000 miles warranty expired 2023. The code that was present at the time was p0301. This is a safety concern this vehicle will leave u stranded and in worst case scenario dead because of engine failure. Lincoln should recall the engines on these vehicles!

In the ecoboost 2.0 models, The engine block has a failure point which Ford is aware of and coolant leaks into combustion chambers and causes misfires, constant loss of coolant, and possible total engine failure. The 1.5L engines were recalled for same exact issue. So far, Ford is unwilling to do anything about this potentially disastrous issue that affects thousands of ford/lincoln owners. Repair costs are over $9,000.

Coolant leakage into #4 cylinder due to the malfunction of the engine blocks gasket. Yes, the vehicle is available for inspection. I live in the country so if there is a breakdown the possibility of me being stranded on the highway or on some back road would be terrible. Yes, I had a mechanic look it over and confirm, Engine over heated on Saturday, daughter and son came to bring antifreeze and water. Had no idea where the coolant had gone, looked for a leak and found none. 2 days later the engine light came on, had mechanic come out and put code reader on it. The #4 cylinder we replaced spark plugs, 2 days later the engine light came on, mechanic replaced the # 4 coil. Nothing is working.

The contact owns a 2017 Lincoln MKC. The contact stated that while driving at an undisclosed speed, the check engine warning light illuminated. The vehicle was taken to an independent mechanic, who determined there was a misfire in cylinder #3, resulting in damages to the engine. The contact was informed that the engine needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure but referred the contact to the NHTSA Hotline for assistance. The failure mileage was 71,000.

Blown head gasket

A couple weeks after recall of battery monitor sensor and an oil change was done (NHTSA CAMPAIGN ID: 23V378000) at a Lincoln dealership, cylinder 1 had a misfire and check engine light came and has stayed on. The vehicle has 61,000 miles and I am now told, by the dealership, it has coolant intrusion. Again the vehicle was taken to the same Lincoln dealership that did the original work. Research seems to show the 2017 Lincoln MKC has a known issue. Ford has technical service bulletin # 19-2346 released 19 December 2019 and it appears that do not disclose this to avoid fixing under their 6 year or 70,000 mile warranty. They redesigned the 2.0L ecoboost engine in 2020. Our engine could fail and put our 3 year old son at risk of injury.

Through testing at Fiesta Ford in Indio, CA, it was determined that my 2017 Lincoln MKc had a blown engine which needed to be replaced. Fiesta Ford determined that there was coolant intrusion on cylinder #1. Fiesta Ford then removed and replaced the engine long block assembly and coolant.

Intermittent P0302 CEL codes fired for Cylinder 2 misfire, over last month. Replaced plugs and coil, Code cleared. Same CEL indicator and code fired again. Symptoms are Rough start up, coolant needing replenishment, took into dealer, coolant intrusion into cylinder 2 requiring engine replacement. This is obviously not an isolated incident with this 2.3L Ecoboost engine, what was know by Ford to flawed during the 2017-2020 period. Two months after purchase of my 2017 MKC, had to have the short block replaced, under warranty, but the head was already warped and they replaced the head gasket on a warped block knowing it was only a matter of time that it started leaking. Now out of the range of that warranty and with looming $8k expense, not happy.

Car acted like it was overheating. It broke down on the road and did not turn back on. Due to it being broke down on the road the vehicle was towed and now I have an outstanding fee to get it out of impound.

I don’t have the eco boost engine so they told me my car is NOT in the TSB even though I was just told that I need a new engine due to coolant intrusion. I have a ford engine with a defect that caused the problem!! Only MKC’s with eco boost are included. How many people with these ford engines are affected but not included??

-Coolant intrusion into cylinder heads, causing engine issues and overheating -Requires full long block engine replacement -Known issue by manufacturer, TSB 22-2229, no support to fix outside of warrant -Confirmed by manufacturer, dealer, independent servicer -No warnings prior to issue

Recently, my 2017 Lincoln MKC has exhibited concerning symptoms that warrant further investigation. Upon starting the engine, I have noticed a slight but noticeable tremor. Though this subsides once the vehicle is in motion, a persistent roughness persists during gear changes, accompanied by the emission of white exhaust from the tailpipe. The situation escalated further with the illumination of the "Check Engine" light. Consequently, I sought professional diagnosis from a certified mechanic. Unfortunately, the diagnosis revealed a significant issue: a broken head gasket leaking into the engine. Remedying this requires a complete engine rebuild. Disturbingly, the mechanic indicated that this problem is not entirely uncommon in Lincolns, and even a full rebuild may not guarantee a permanent solution. I have come across information regarding a class action lawsuit entitled "Reed et al v. Ford Motor Company 2:2021cv00417," which I intend to contact to report my experience and contribute to their investigation. Additionally, I have contacted the original dealership where I purchased the vehicle and am actively exploring all available options to address this concern.

The head gasket leaked resulting in having to put in an entirely new engine. The dealer suggested that this was a known issue and that the gasket breaks in the corner. After the replacement, I was told that the manufacturer improved the gasket and I should not see this issue happen again. When the gasket blew, there was an immediate loss of power going down the expressway.

TSB 19-2346 ... Engine gives no warning until to late ... Then multiple warnings and alarms happen all at once ... says the car is overheating but before you have time to react (Like pulling over) the alarms clear ... engine light is only warning on ... This could cause the motor to seize or stop running loosing power steering and control ... This has been known since 2019 when TSB-19-2346 was announced which means they knew sooner ... Ford told me there is no known problem with this motor but TSB says other wise ... There is no fix to problem .. Motor replacement is it ... I purchased this car from ford Dealer 09/19/20 with 25000 miles ... I never got any notice on the car and the problems it was having ... now they want me to pay out of pocket for new motor $7000 ... we still owe $20000 on the car and its down ...

Coolant leaking into the cylinder. Had it serviced at 69.4K miles with a radiator flush and 3,000 miles later the warranty has expired and we have coolant in the cylinder. The fix is an engine replacement, $11K. There is a technical bulletin out so they this is a common problem, however they seem to let the issue go without notification in hopes the warranty's expire.

When I started my car is was idling low and engine light came on

I purchased my vehicle from Randy Wise Hyundai formly Randy wise Lincoln Auto Mall here in Flint MI on 4350 Lennon Rd 48507 on June 8 2020 is the date i purchased it i only had it for 8 months i am still paying a car note and car insurance on it i am spending countless of money on it i have to pay 7245.00 on a brand new engine as i speak luckily Lincoln Motor co in Dearborn MI is going half i just want to know if i can get refunded my money and the dealership knew of this problem and still was selling these types of vehicle even the service manager informed me that this is common for these types of vehicles to have these issues why still sell them to the consumers this has caused me a lot of hardship , Darrell Chisolm Jr.

WHILE DRIVING THE VEHICLE WILL SUDDENLY ACCELERATE UNEXPECTEDLY AND ON MORE THAN ONE OCCASIONS I ALMOST CRASHED INTO THE VEHICLE IN FRONT OF ME. TOOK THE CAR TO MY MECHANIC AND HE STATED THAT THIS IS A KNOW PROBLEM WITH THIS ENGINE AND LINCOLN IS REPLACING THE ENGINE BUT I CHECKED WITH LINCOLN THEY SAID THERE ARE NO SAFETY RECALLS.... **

THE ENGINE LIGHT CAME ON AND THEN THE VEHICLE STARTED TO LOSE POWER

I STARTED THE VEHICLE, THE SYNC SYSTEM WENT THROUGH A RESTART, KILLING THE ENGINE AND TURNING OFF THE DASHBOARD PANELS. IT HAD HAPPENED BEFORE ON A LEVEL SURFACE, BUT THIS TIME I WAS ON A 10-15% GRADE. I STOPPED AGAIN, TURNED THE VEHICLE OFF AND RETURNED ABOUT 15 MINUTES LATER. I WAS ON A SLIGHT HILL, WITH THE ELEVATION LOWER IN FRONT OF THE VEHICLE. I STARTED THE CAR AND STEPPED COMPLETELY OUT WITHIN 10-15 SECONDS. I STEPPED OUTSIDE THE VEHICLE, WHICH HAD BEEN RUNNING FOR 10-15 SECONDS. THE HATCH WAS OPEN AND TWO FRIENDS BEHIND COULD CLEARLY SEE THROUGH THE VEHICLE, TO KNOW THAT I DIDN'T TOUCH THE PUSH BUTTON TRANSMISSION. THE VEHICLE STARTED ROLLING DOWN THE HILL. I JUMPED IN, BUT THE BRAKES DIDN'T WORK AND THE INSTRUMENT PANEL WAS DARK. IT STOPPED ROLLING WHEN IT COLLIDED AGAINST A PARKED TRUCK APPROXIMATELY 50 FEET IN FRONT. THE ENGINE WAS OFF WHEN IT STOPPED. I THINK THE RECYCLE OF THE SYNC SYSTEM CAUSED AN INTERMITTENT MALFUNCTION OF THE ELECTRICAL SYSTEM, CAUSING THE BRAKES, STEERING AND PUSHBUTTON TRANSMISSION TO BECOME NON-OPERABLE. THIS RESULTED IN DAMAGE OF $8568 TO MY MKC AND OF $1512 TO THE PARKED TRUCK. SINCE THIS IS AN INTERMITTENT INCIDENT, IT CAN'T BE REPLICATED AT A DEALER EVEN IF IT HAPPENED, IT WOULD BE ON A LEVEL SURFACE AND WOULD NOT ROLL. I HAVE DRIVEN THE VEHICLE FOR AN ADDITIONAL 7 MONTHS AND 8,819 MILES. THE CURRENT MILEAGE IS 27,474. DURING THAT TIME, THE VEHICLE HAS STARTED AND THEN GONE THROUGH AN ELECTRICAL RECYCLE WHICH CAUSED THE ENGINE TO TURN OFF AT LEAST 5 TIMES. TWO OF THOSE TIMES WERE ON A FLAT SURFACE. I RAN OVER A COONCRETE CURB A MONTH AGO. TONIGHT IT HAPPENED IN MY DRIVEWAY & RAN UP ONTO MY FRONT PORCH, WHICH HAS A STEP UP OF ABOUT 6 INCHES. I CALLED LINCOLN CONCIERGE TO REPORT THE 2ND INCIDENT. THEY TOLD ME THAT THEY COULD DO NOTHING UNTIL THE PROBLEM WAS RECREATED IN A GARAGE - OR IT KILLS OR INJURES SOMEONE.

FIRST NOTICED THE PROBLEM WHEN I HAD NO HEAT BLOWING FROM MY HEATER, (CAR WAS NOT OVERHEATING OR ANYTHING), I CHECKED MY ANTIFREEZE AND IT WAS LOW SO I ADDED IT AND I HAD HEAT IN MY CAR AGAIN. FOUR DAYS LATER, I HAD THE SAME THING HAPPEN, NO ANTIFREEZE (AND AGAIN NOTHING SHOWING MY CAR OVERHEATING), ADDED ANTIFREEZE AND HAD HEAT AGAIN. PARKED MY CAR ON A CEMENT DRIVEWAY AND OBSERVED NO ANTIFREEZE LEAKING, BUT THERE WAS A VERY STRONG AND HORRIBLE SMELL OF ANTIFREEZE BURNING COMING FROM MY EXHAUST ALSO, THINK WHITE SMOKE COMING FROM THE EXHAUST. CAR IS NOW WAITING AT THE FORD DEALER TO FIND OUT WHAT IS WRONG. CAR ONLY HAS 49,852 MILES ON IT.
