2017 LINCOLN MKC Engine Problems

At approximately 64,000 miles my engine light came on and I took it to a shop. Cylinder 2 was misfiring so we changed the spark plugs and coils. At 67,000 miles light came on again with same issue and while having my oil changed they noted it was unusually dirty. I changed out plugs and coils again. At 72,000 miles light came on again and I took it to a different shop and learned I had a crack engine block, a problem with these vehicles with ECO boost. I was told I needed a new engine and the only thing I could do was add sealant to buy time. I took it to Lincoln to trade and they refused because of the issue and told me to reset the light and sell to Carmax. I couldn’t do that, it was wrong. I sold it for $1,000 to Nissan because I...

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.

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 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...

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...

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...

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...

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

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.

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 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.

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...

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...

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...

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...

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.

The manufacturer was notified of the failure, but no assistance was provided. The failure mileage was approximately 107,000.

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....

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...

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...

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.
