Engine And Engine Cooling Problems of Lincoln MKC - part 2

About 3 weeks ago, I was driving, and a red flashing light came on, signalling that my coolant was low. I bought radiator fluid and put it in up to the fill line. I visited my daughter, which is 11/2 hr. Away. I checked the radiator reserve when I arrived at her house. The reserve was empty again. I brought it to a local mechanic shop. They diagnosed that I have coolant intrusion in the engine. They said I would need to pay for a new engine around $8800-$9200. I had purchased a lifetime extended warranty when I purchased the car. The Ford dealership diagnosed my car with the same problem as the local mechanic. They said the repair was not covered by the powertrain warranty do to it being a manufacturing failure. I brought the car home and it has been parked since.

I own a 2018 Lincoln Mkc equipped with the 2. 0l ecoboost engine. The vehicle currently has approximately 72,326 miles. The check-engine light initially illuminated and an obd scan produced code p0303, indicating a misfire in cylinder 3. No other diagnostic codes were reported. Following mechanical evaluation, all four spark plugs and ignition coils were replaced. Approximately 145 miles later, the check-engine light returned with the same p0303 code. The code was cleared to confirm recurrence, and approximately 111 miles later the check-engine light illuminated again. I subsequently took the vehicle to a Ford/Lincoln dealership for further diagnosis. The dealership determined that coolant is leaking into cylinder 3 and advised that the required repair is replacement of the engine/long-block assembly, at an estimated cost of approximately $8,900. I have since learned that Ford issued technical service bulletin 19-2346 addressing certain 2017–2019 Lincoln Mkc vehicles equipped with the 2. 0l ecoboost engine that may exhibit coolant intrusion into the cylinders, an illuminated malfunction indicator lamp, and misfire diagnostic codes including p0303. The prescribed repair under the bulletin may require replacement of the long-block engine assembly. A search of NHTSA's recall database using my VIN does not presently identify my vehicle as subject to a safety recall for this coolant-intrusion condition. I am submitting this complaint so that NHTSA has a record of another 2018 Lincoln Mkc 2. 0l ecoboost experiencing a dealer-confirmed coolant-intrusion failure consistent with Ford's published technical guidance. I am particularly concerned about whether this failure mode has safety implications and whether the population of potentially affected vehicles has been adequately identified. The vehicle had not exhibited significant drivability problems, rough cold starts, or other obvious warning symptoms before the recurring p0303 check-engine indication.

Lincoln Mkc 2017 engine failure due to coolant leak. Bought new Lincoln Mkc 2017. The current mileage is 52, 500. Upon starting, engine would shake for about 10 seconds. The engine light would come on. Engine light would turn off and on for few weeks. The dealership diagnostic indicated code p0301. I was advised full engine replacement. Currently the engine is not starting at all. I have heard it's a design issue with the engine. I have contacted multiple Lincoln dealerships, and each one has its own engine replacement costs. Lincoln concierge declined my request to help in anyway although it seems to be a design issue with the engine.

The contact owns a 2017 Lincoln Mkc. The contact stated upon starting the vehicle, the vehicle idled roughly, and there was white smoke coming out of the exhaust. The contact stated that the vehicle was experiencing excessive coolant consumption, and the low coolant temperature warning light was illuminated. The vehicle was taken to the dealer, where it was diagnosed that the engine had failed and needed to be replaced due to coolant intrusion. The vehicle was then taken to an independent mechanic, where it was determined that the engine replacement was not required, but the head gasket needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure and informed the contact that the VIN was not included in a recall. The failure mileage was approximately 135,000.

Dealer confirmed there is a coolant intrusion in the engine and the engine needs to be replaced due to a known defect.

The contact owns a 2016 Lincoln Mkc. The contact stated that while driving at an undisclosed speed, the check engine warning light illuminated. The vehicle was taken to a dealer, where it was diagnosed that the supercharger-a and the under boost needed to be replaced. The vehicle was repaired; however, the check engine warning light was illuminated again. The manufacturer was not notified of the failure. The failure mileage was approximately 60,000.

To NHTSA: I am filing this complaint about a dangerous stall/overheat defect in my 2019 Lincoln Mkc, VIN [xxx], currently at 79,820 miles. This vehicle was built 2018-10, before Ford's engine redesign, and it is now undrivable due to coolant intrusion into the engine, a known and documented defect covered under Ford TSB 22-2229 for the 2. 0l ecoboost engine. What happened: the car overheated on me at church's chicken. I came out with coolant to top it off, and cautiously drove it to dr underhood repair shop. They ran the codes and quoted a full engine replacement, but couldn't source an engine, so they sent me to the dealership. I paid them and limped the car across town to randall Ford. Randall Ford confirmed the failure matched the TSB. I paid them too, and the car overheated again within 500 feet of leaving their lot. I had to park it at a strip mall and have it towed to our warehouse, where it sits undriveable today. Randall Ford's diagnosis (repair order xxx, dated xxx) is coolant leaking into the engine, requiring a new engine, quoted at $16,735. 60. The codes pulled were p0217, p0303, p0316, p0420, and p06e9 - overheat, misfire, misfire, catalyst efficiency, and turbocharger coolant/fluid, all consistent with the coolant intrusion pattern described in TSB 22-2229. I confirmed rough running, and the car overheating with no visible external leak, which matches the pattern in Ford's own bulletin. I am aware Ford issued csp 21n12 to extend coverage for coolant intrusion on the 1. 5l ecoboost engine, but no equivalent program or recall exists for the 2. 0l ecoboost engine in my Lincoln Mkc, despite the same defect and the same TSB language applying. There has been no recall issued for this problem on my vehicle at all, even though Ford is well aware of the defect. I also want to note that this is not an isolated issue with this vehicle - I have separately experienced the documented purge-valve/fuel-system defect on this same car, which suggest information redacted pursuant to the freedom of information act (fo.

Engine failure TSB 19-2346, a known/common issue with this engine. The car only has 73,790 miles on it. The car started shaking when started, engine light on, empty coolant reservoir and off then parking brake came on randomly several times , and the brakes locked up twice, which resulted in going over a curb. Discontinued driving the vehicle after that incident obviously due to safety. Ford service center gave a $13,000 repair estimate. The vehicle is still at Ford and available for inspection.

I took my vehicle to the local Ford dealership for service due to a check engine light being on. They pulled the spark plug and found the cylinder full of coolant and found TSB-22-2229. I called Lincoln and was told they wouldn’t assist me because I fell outside their time and mileage limits. This issue should have been a recall due to their defective engine design. Engine replacement is very costly and the company should take responsibility for this flaw.

Issue description: the vehicle developed a check engine light and was diagnosed with a p0302 cylinder #2 misfire. The condition persisted after basic troubleshooting, and the vehicle was taken out of service to prevent further damage. The vehicle was subsequently brought to an authorized Lincoln dealership for diagnostic evaluation. The dealership confirmed that the vehicle requires a full engine replacement due to internal engine failure. The estimated cost of repair is approximately $9,500–$10,000. This failure occurred at approximately 64,000 miles, which is significantly earlier than expected for a major engine failure. Safety concern: the engine misfire and internal failure can lead to loss of power while driving, creating a potential safety hazard, particularly at highway speeds or during acceleration. Additional information: manufacturer technical service bulletins describe coolant intrusion issues in 2. 0l ecoboost engines that can lead to misfires and engine damage. The symptoms experienced in this vehicle are consistent with those described conditions. The manufacturer was contacted for assistance but declined to provide support. Summary: premature engine failure at low mileage requiring full engine replacement, with symptoms consistent with documented issues affecting this engine type. This condition presents a potential safety concern due to possible loss of power while driving.

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 check engine light came on and car started to over heat when taken into shop was told need to replace entire engine this is a known issue in these make / model cars with these engines and it is not being addressed.

The contact owns a 2019 Lincoln Mkc. The contact stated that the engine experienced rough idling after starting with the check engine warning light illuminated. The vehicle was taken to an independent mechanic, who replaced the spark plugs and coil pack; however, the failure recurred with the vehicle shuddering while driving. The vehicle was taken to the dealer, who determined that the engine needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 58,000.

Purchased a 2019 Lincoln Mkc from Mazda and stokes on ashley phosphate in north charleston, south carolina. I was told that the vehicle had recalls and they identify the recalls about the battery and the rear camera when I asked was there anything else wrong with the vehicle, they said no when I drove the vehicle home after a few days the engine light came on. After doing some diagnostics at the dealership, it will discovered that there was a misfire in the engine. They did a complementary repair. It took a couple of days when I received the vehicle. I took it home and after about a week, the engine light came back on for the same problem after further diagnostic come to find out that if this problem persist is because of coolant intrusion come to find out that this is common among engines that are 2. 0 l eco boost engine engines in the 2019 Lincoln Mkc. I am making a complaint because I found out also that I will not get reimburse my money. Neither will they take the vehicle back. I called the Lincoln dealership and they will not do a goodwill repair so I purchased a car about three weeks ago with them, knowing this problem and did not disclose it to me or told me about it cause this is common knowledge for this vehicle and they sold it to me and now I have payments on a broke vehicle, which I can’t afford $11,000 new engine or a long block.

Coolant intrusion into the engine at 20000miles. Complete engine failure. Lincoln dealership diagnosed that a long-block engine replacement is required. Serious safety hazard due to potential sudden stalling while driving.

My 2019 Lincoln Mkc has the widespread coolant intrusion engine defect acknowledged by Ford. This is a premature internal engine failure due to design.

Ford's 2. 0l ecoboost engine has seen recalls and technical service bulletins (tsbs) primarily for coolant intrusion leading to engine failure, affecting models like the 2017-2019 Mkc with issues stemming from a block design flaw and faulty head gaskets that allow coolant into cylinders, causing overheating, corrosion, and potential engine fires. This vehicle is confirmed to have coolant intrusion in the cylinders, resulting in premature engine failure.

The contact owns a 2019 Lincoln Mkc. The contact stated that the messages "service advancetrac", "hill start assist not available", "system off - to save battery please turn off ignition or start engine" were displayed. The vehicle was taken to the dealer, where it was diagnosed, and determined that the battery and the battery monitor sensor had failed and needed to be replaced. The parts were ordered to repair the vehicle. The vehicle was not yet repaired. The contact related the failure to NHTSA campaign number: 23v378000 (engine); however, the VIN was not included. The manufacturer was not notified of the failure. The failure mileage was approximately 98,000.

Vehicle overheated, due to collant entering #1 cylinder. This coolant intrusion is apparently a well documented issue, from an acknowledged engine defect. (TSB 19-2346, TSB 22-2133) Ford dealership recommended an $11,000 + tax engine replacement, with no relief, as car is past its warranty. The vehicle has 58540 miles. Lincoln customer service also declined any goodwill repair. Independent service dealer (craig’s auto repair service 281-469-5949) first diagnosed the issue, recommended taking the vehicle to Ford dealership (tomball Ford).

Engine warning light went on. Replaced spark plugs and coil to cylinder # 2. Then, traction control light indicated system off. Technician advised the need for dealership software upgrade to abs. Dealership advised that engine block allowing coolant intrusion into #2 cylinder. Needs a new engine. And need for a new abs module, also defective.

I have a coolant leak and the dealership states that it's located in the engine.

Vehicle unresponsive after sitting idol at traffic light. When trying to accelerate, no power. Vehicle was still running, but unable to accelerate. Finally able to accelerate after rpms up to nearly 3000 rpms, and slow to respond and accelerate. Engine warning code on dashboard soon after. Error code is p0751, shift solenoid a performance stuck or off. Similar issue when under warranty in 2022 with 22,000 miles.

For the last 17,000 miles, the engine light has been on. We got it checked out and there is coolant and cylinder three we change the cylinder thought it was a misfire, but the problem keeps occurring and we found out information that those engines are bad.

The head gasket has failed, leading to coolant intrusion into the number 2 cylinder. Several misfires occurred due to this. This is a known issue due to the design of the lower block, which uses a channel, thus causing a very small surface area for the head gasket between the channel and the cylinder, which accelerates wear. Spent $3,000 to fix this well-known design issue. Car at ~100k miles.

My 2019 Lincoln Mkc with only 52,200 miles experienced unrepairable engine damage due to an internal coolant intrusion condition that directly matches Ford TSB 22-2229. On or around Jan 1st or 2nd, a check engine warning light came on as I was driving home at night. I did not drive my car any further except to the dealership for service on 1/5/2026. The engine failure was diagnosed by the dealership on 1/6/2026. This engine failure occurred well below a reasonable engine life expectancy, and is caused by a documented design defect. The manufacturer’s refusal/delay in recalling these engines with a known design defect places drivers at risk of being stranded at any time of day or night, and drivers risk becoming a road hazard to themselves and others when experiencing complete engine failure.

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.

I was driving home from work on December 24th 2025 and my 2018 Lincoln Mkc 2. 3l shut off on me while I was in motion. There were several cars that had to swerve and not hit me. The car would not start but I was able to put the vehicle in neutral and roll to the shoulder of the road. I was very scared and angry because this vehicle only has 54,646 miles currently, give or take 50 miles. I had to get the towed to my home. This needs to be resolved and fird/Lincoln needs to faithfully fix this dangerous defect, I could have died. Please please do something because I do not want anyone else to deal with this.

I have coolant intrusion in cylinder #2 91000 miles this should be a recall it's a problem that's well documented there's a recall for the back up camera hope the camera can see through the white smoke!.

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

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

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

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

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