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 have a 2018 Lincoln Mkc with approximately 58,000 miles, always taken care of and maintained, in excellent condition. Almost immediately after my extended warranty ran out the check engine light came on and it started to start and idle rough. Took it to a Lincoln dealer, they replaced coil assembly # 4 and the 4 spark plugs, told me if it continues there might be coolant intrusion to the engine and the engine would need to be replaced. Check engine light came on 2 days later again, back to the dealership where they told me there was coolant intrusion and the engine will need to replaced. $8020. 00 estimate, Lincoln/Ford is aware of this defect in this engine, they should recall this engine and replace it.

Check engine light came on at approx 54,000 miles with code of cylinder 2 misfire diagnosed as spark plugs and ignition coils need replaced. All spark plugs and ignition coils replaced may 11. June 23 check engine light on again with cylinder 2 misfire. Was told spark plugs and ignition coils need replaced again. July 9 spark plugs and ignitiion coils replaced. July 10 check engine light came on cylinder 2 misfire. July 11 car was diagnosed as needing engine replacement due to coolant intrusion causing rust in engine.

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.

My 2019 Lincoln Mkc with a 2. 0l ecoboost engine experienced coolant intrusion into cylinder 2, leading to engine misfire, check engine light, and severe vibration. The dealership confirmed the issue and recommended a full long block engine replacement, estimated at over $11,000. This failure occurred at only 48,000 miles. This appears to be the exact issue described in Ford TSB 19-2346, which covers 2017–2019 model year vehicles with the 2. 0l ecoboost engine, including the Lincoln Mkc and mkz. The TSB acknowledges a design-related coolant leak into the engine cylinders that can cause white smoke, misfire, rough running, and warning lights. Ford’s recommended repair is to replace the long block assembly. I believe this is a widespread design defect and request NHTSA’s investigation to ensure proper manufacturer accountability.

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.

Only 69,000 miles and have engine failure. Car shut down on the highway and put me and my child in a very dangerous situation. Dealership diagnosed it as coolant intrusion into the engine. Seems to be a widely known problem with the Mkc. The engine now must be replaced and the cost is more than the car is worth.

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.

Loosing coolant resulting in coolant leaking into the engine. White smoke coming from exhaust m. Repair garage states only fix is to replace with revised engine causing over $10,000 in repair costs.

Was uninformed about previous recalls to this same make and model that took place prior to me getting this vehicle. Was told by Ford dealership recently once I took the vehicle for diagnostic for engine light being on that coolant has been leaking into the engine and would require a brand new engine. This has been a manufacture issue that Ford has been made aware of years ago and has done absolutely nothing about.

I purchased a 2016 Lincoln Mkc 2. 0 with 96k miles on it 2 months ago, and we just discovered a coolant leak into the first cylinder, causing a cracked head gasket. The engine needs to be replaced, and will cost $15k. Many other drivers have experienced this problem and reported it, and Ford has done nothing to correct the main issue. This problem is causing overheating of the engine, and could potentially cause injury if not fixed.

The engine light has appeared approximately in April 2025. The inspection advised that the engine code indicated a misfire in cylinder 4. The engine rough idles when started. The coolant loss is extensive due to an engine issue and must be constantly filled. Vwe were told by, ipaul's repair shop, that upon calling Ford, that there was a Lincoln technical service bulletin the 2 liter eco boost engine. It was re coolant intrusion into the cylinders. Service bulletin # 19-2346. We have also replaced the spark plugs and coils. The engine light still came on with the same issue. It did not solve the problem of a defective engine.

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

Coolant is being blown out of the cars tailpipe. Opon cranking . There's a lot of white smoke. Lately every three days I have to add antifreeze to the coolant reservoir. Car was inside of my yard and parked.

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.

I started my car with no prior warning light or malfunction alerts on my dashboard or Lincoln phone app. Upon shifting into drive, the vehicle began shaking severely, accompanied by a loud rattling noise for the first time. I had the car towed to a Lincoln dealership, where they evaluated the issue (see attached file for their conclusion). Seeking a second opinion, I had it towed again to an independent service center, where they determined that a cracked electrical plug caused a transmission fluid leak. The defect put our safety at risk, as I was unknowingly driving with transmission fluid levels below the minimum and blackened oil. As a result the transmission had to be replaced.
