While driving my 2017 Lincoln MKZ 3.0L in March 2023, I experienced a loss of power and then engine stalled, fortunately I was at a stop and was able to re-start the vehicle and limp home, (which was nearby). If this loss of power and then stall would have happened while I was moving in traffic the failure could have lead to a catastrophic outcome including loss of life. It was determined via OBDII analysis conducted by the Lincoln Service department that DTC P0302 was triggered. Upon further inspection by the service department it was revealed that the issue was related to TSB 19-2243, which reads "2.7L/3.0L - Oil Consumption With DTC P0524 And/Or P06DD, Rough Idle, Misfire And/Or White Or Blue Exhaust Smoke - Built On 1-Apr-2016 And Through 1-Jan-2017". Unfortunately, my vehicle was built during this known defect time frame. And the remedy required new cylinder head. The new cylinder head and subsequent parts and labor cost me $3,126.58. This was extremely unfair as my only because my vehicle did not fall within the warranty period or mileage. The vehicle was over 6 years old with 36,934 miles. This very serious failure mode could have resulted in a loss of life if experienced while driving on a highway or any other situation in which the vehicle was mobile and experienced a sudden loss of power in traffic. Further disappointing is that I would estimate that there were many vehicles that experienced the defect noted in the TSB but these were not reported publicly because they were "lucky enough" to fail during the warranty period. My costs should be reimbursed by Lincoln given this was a known defect during the build time frame. And at minimum there should be a safety recall for the vehicles built during the time period noted in the TSB. I will personally never purchase another Lincoln not to mention a Ford, of which I currently have 3 Ford/Lincoln.

In September 2022, I began noticing issues with my 2017 Lincoln MKZ. Despite notifying Lincoln and the dealer, they delayed inspection due to their policy that a check engine light was not a sufficient reason for an early inspection without an appointment. It was only inspected in November. I also was told both by the dealer and Lincoln corporate customer service that I couldn't take my car to other dealers to get it inspected. In November 2022, it was finally inspected, but they were unable to diagnose the issue. By July 2023, the issues escalated - my car was now diagnosed as requiring a new engine due to coolant leakage into the engine. I was shocked and horrified at this outcome, given that I had only driven the car for 25k miles since its purchase in 2020. Over a third of submitted complaints to nhtsa regarding this vehicle model are related to engine failure due to coolant leakage. TSB reports and existing class action lawsuits indicate that the issue is a known design flaw in the engine affecting both Lincoln MKZ and certain Ford Fusion models. Technical Service Bulletin (TSB) 22-2134, indicates that the problem may present "with or without an illuminated malfunction indicator lamp (MIL)". A complete engine replacement is their proposed solution. Despite the urgent need for corrective action, Lincoln's response has been neither prompt nor transparent. They seem to be avoiding responsibility rather than addressing this critical defect, as evident in their decision to discontinue the MKZ and the Ford Fusion in 2020 a year after acknowledging these issues. This is a case of warranty and insurance fraud, not to mention a critical failure in maintaining public safety. I urge NHTSA to thoroughly investigate this defect affecting numerous vehicles and compel Lincoln to rectify it. For the past two weeks, I've requested multiple times my vehicle records from Lincoln but received none, leaving my car hostage in the shop. Please consider this plea for action.

Engine light would come on & off. Took my care in to be inspected - they determine i need a new motor -due to defect in motor design leaking antifreeze into cylinders. Not cover by warranty because i was 2 months out of the 6yr. period with only 47,000 miles on it. They will do nothing for me except charge for a new motor. My understanding is this 4 cylinder w/turbo motor in Ford/Lincoln has a known design flaw that they hope no one finds out about.

This vehicle already has a TSB reported, TSB 22-2229. There is a known defect in the manufacturing of the engine design. The design is failing and allowing coolant to run into the engine cylinders. This puts drivers at risk, not knowing when the engine may completely fail while driving it. The engine heats up quickly when the coolant is drained into the engine (default design), instead of around the turbo engine. There is no coolant left in the reservoir, thus possibly causing an engine fire. I've had a diagnostic check on the vehicle at Blue Springs, Mo Ford. They report that the engine will need to be replaced. The service engine light comes on, but the code read doesn't come up as the engine. It is a spark plug/coil pack needed for replacement. This has been done. I've had the engine overheating warning come up. I've had to add antifreeze to the reservoir several times. These warning lamps and messages have been coming up for the past 2 weeks. The car starts off rough, with some misfires in the idle. I have had it not start at first and I will have to try again several times.

I have a 2017 Lincoln MKZ with the 2.0T Ecoboost engine and have approximately 74,000 miles on the car. I have been receiving a check engine light which indicates a Missfire on Cylinder 2 when scanned. Additionally I have noticed low coolant levels in the reservoir. I have had a loss of heat in the winter which lead to the initial discovery of low coolant. No indicator light came on when the coolant was low. I replaced the spark plugs in all 4 cylinders which has not solved the issue. Additionally, I still experience coolant loss. I took the car to the Ford Dealership which informed me I have coolant leaking into Cylinder 2 which will require a new engine. Had the coolant not dropped as low as it did in the winter, I would not have noticed the loss of heat and therefore checked the coolant level as there were no other indicators of low coolant level. This could have caused significant overheating issues and even complete engine failure.

- Monticello, MN, USA

Vehicle starting and running rough upon start up. Coil #2 now showing bad 4th time within the past 6-8 months, the #2 plug twice on the last month. Now coil #3 and plug for the 2nd time. Feels like an Oxygen sensors going bad, although no codes showing up for that, causes the check engine light to come on and continually run rough like a misfire.

I purchased this 2017 Lincoln MKZ 2.0L used on 11/26/22 with 72,400 miles. 2/4/23 I started having a misfire on cylinder 2. Past experience with another Ecoboost vehicle I thought was most likely a failing coil pack. I purchased an OEM coil pack and replaced coil pack 2. The car ran fine for several weeks and I thought my issue was fixed. 3/18/23 I left the house and typically before I get to town I-??d have heat in the cabin, that wasn-??t the case. I looked at all gauges and everything is normal no lights & engine temp is fine. Pull over and looked at the coolant reservoir-?? bone dry! I look for external leaks, but there are none. Filled the reservoir and I now have heat again. I got it home and looked all over for a leak again, but nothing. Figured well since I had a misfire and I-??m approaching 80,000 miles maybe I should do the spark plugs. Cylinder 1 came out fine, and cylinder's 2,3,4 all seemed to be seized to the point I didn-??t feel comfortable using more force and risking them breaking. Checked the oil and the oil looks fine. The engine runs rough upon the first start of the day, and white smoke is released from the exhaust while this is happening. Decided to take it to a local Ford garage and have them do the 3 remaining plugs as well as an oil change as I thought maybe it was a spark plug issue. I explained my experience with the vehicle and the service tech stated they won't touch them because this is a known issue. Most likely I would need a new engine. Apparently, with this gen of the Ecoboost 2.0, there is coolant leaking into the cylinders due to a manufacturer design flaw that Ford knows about. This coolant will cause the cylinder head to crack and fill with coolant. Ultimately the engine will self-destruct. My local Ford garage told me to reference TSB 22-2229. If you research this online you will find many complaints as well as fears of continuing to drive the vehicle as this could cause an accident when the engine completely dies.

The contact owns a 2017 Lincoln MKZ. The contact stated while driving approximately 35 MPH, and at other various speeds, the check engine warning light remained constantly illuminated. The contact had taken the vehicle to a dealer where it was diagnosed that the vehicle had been leaking coolant into the engine block. The mechanic determined that the engine needed to be replaced. The vehicle had not been repaired. The manufacturer had been informed of the failure. The failure mileage was approximately 50,000.

I was driving and started smelling toxic fumes come inside my car, steering wheel started jerking. I didn-??t think much of it until my 2 year old daughter in the backseat was looking as if she was about to pass out. Her eyes started rolling and her words were slur, more slur than normal. I immediately pulled over and saw the fumes were coming from my tail pipe. It was a huge cloud of smoke. It was my car that was the problem. I had to leave my car on the side of the road and get someone to take us home. It wasn-??t safe to drive in the condition it was in. The next day I got it towed to the mechanic and he said my car lacked coolant and the engine needs to be replaced. I looked online and saw that this was an ongoing problem for the make and model of my vehicle and Ford is aware of it. The mechanic quoted my thousands of dollars to get it repaired. Ford won-??t help. This incident could-??ve killed my daughter and me. PLEASE HELP MAKE MY CAR A RECALL ON THE ENGINE! I have no transportation.

My engine is overheating, causing my steering wheel to jerk while on the highway. Took to dealership and they said loss of coolant and could potentially cause a fire if not treated. Looked online and saw that Ford is aware of the problem but will not correct it. The dealership is asking me to pay $8,000 to fix it for Ford initially putting in a faulty engine. I had to stop my car because smoke was coming out the tailpipe. The car isn-??t safe to drive.

In April 2022 my steering wheel started jerking and I felt my car starting to drive unusual. By the end of April my check engine light was on so I went and got it checked out. Code P0217, P0302, P0316 showed up. I thought this must be a mistake so I took it to the dealership for another look and they told me that this is a common problem with my vehicle and I got the short end of the stick with this vehicle. THE LONG BLOCK NEEDS REPLACING FOR COOLANT INTRUSION INTO CYLINDER 2. I need a brand new engine. The supervisor in the service department said there-??s a technical service bulletin that reads that, TSB#22-2133, Issue: Some 2015-2018 Edge and 2017-2019 Fusion/MKZ/Escape/MKC vehicles equipped with a 2.0L EcoBoost engine may exhibit a low coolant level, white exhaust smoke and/or a runs rough condition with or without an illuminated malfunction indicator lamp (MIL). Diagnostic trouble codes (DTCs) may include P0300, P0301-P0304, P0316, P0217, P1285 and/or P1299 stored in powertrain control module (PCM). This may be due to coolant intrusion into the cylinder. To correct the condition, follow the Service Procedure steps to replace the long block engine assembly. Action: Follow the Service Procedure steps to correct the condition on vehicles that meet all of the following criteria: -??

I own a Lincoln mkz reserve it started running rough and i was informed it had a misfire code and the recommendation was to change the coils and spark plugs, after that was done it still wasn't fixed after multiple items on vehicle changed it stopped running altogether and i was told the engine lost compression and that this is common flaw on 2017-2019 Lincoln engines and that ford even has a service bulletin and my sole remedy was to buy a new engine this isn't right someone could be inured if vehicle dies in traffic on top of the fraud by ford they are selling vehicle that intentionally blow there engine after the warranty period, i have send hundred of other poor soul that this has happened to online. the us government needs to take action to stop this fraud

I took car in to get oil change found coolant leaking. Car has 32000 miles. I went to ford store and they said coolant is leaking out side of engine and cylinders no 3 and 4 have coolant inside Ford replaced engine. 2.0 Eco bost Engine

- Niles, MI, USA

Purchased cpo with 38K miles on it. A week after owning smoke emitted from exhaust, check engine light came on and car was rough to start, idling hard. Car melted strongly of antifreeze but no visible leaks. Lincoln did inspection and says needs a new engine due to coolant leaking into cylinders and pistons failing. Engine is on backorder for two months. This seems to be a known problem. We are extremely unhappy. Haven't even had the car two weeks before this started happening. We want out of this car!

- Longwood, FL, USA

Started have problems with the heat on the car, took it to the Ford dealership and was told the engine needed to be replaced. According to tsb 19-2346 it is a known defect with this model of vehicle and they refuse to pay for repair due it being out of warranty.

Vehicle stalls/loses power once fuel reaches below half tank of gas. Ford has issued tsb's on this very issue on many of their other engines, but I've been unable to find a tsb for this issue for my vehicle specifically. Here is the tsb for Ford Focus's with this issue: Ford Motor Company (Ford) is recalling certain 2012-2018 Ford Focus vehicles with a 2.0L gdi or 2.0L gtdi engine. The canister purge valve (cpv) may malfunction, possibly causing excessive vacuum in fuel vapor management system. Tsb # 18S32. When pressure is being released from the gas tank via the fuel door opening, gas sprays out of the opening and goers stuck/hardened to exterior of car.

While driving in heavy traffic on the interstate attempted to change lanes and accelerate, car suddenly lost power and the "see manual" light illuminated with tool - fortunately was able to coast car off exit ramp safely and pull over, at which point the engine chugged and stalled. First restart "see manual" light still on, sputtered and stalled. Turned off vehicle. 2nd attempt same as 1st. 3rd came on and ran without engine light and seemed to rev up higher than normal, then came back down. No other indications appeared other than "no use of auto brake available"
