While driving the car in commuter traffic on Route 22 Highway the car transmission stopped working and car bucked and then stopped. Upon getting out of the lane of traffic there was a large amount of transmission fluid on the ground. Car had to be towed as it would not move. Danger was the car stopping on the highway in busy traffic. Upon inspection by car dealer they found it had a broken transmission cooler line . The Lincoln dealer put in a Tube Assembly repair kit and replaced all trans cooler lines at a cost of $ 1,029.72 to me. No Warning lamps or messages came on before the lines broke.

Approximately 2 weeks ago, my 2017 Lincoln MKZ Reserve began sputtering/hesitating during acceleration. On 03/31/2025, I took it to the Heiser Ford-Lincoln in Glendale, WI for service and the diagnosis was I needed to replace my “engine long block” because of engine coolant leaking into the engine cylinders. I was given at an estimated cost of $8,000. I researched and found Technical Service Bulletin 22-2229 listing this issue as a not-so-uncommon problem with Ford’s 2.0 Liter engines. I am highly concerned that this could cause the engine to seize while driving with coolant compromising the viscosity of the engine oil. I firmly believe this should be elevated to a Recall status as this engine is used in several 2017 through 2019 Ford and Lincoln car models - and the occurrence has been frequent enough to have a TSB created.

I have purchased a used 2017 Lincoln MKZ Reserve 2.0l in August of 2023 that started losing coolant and smoking from exhaust. Upon further investigation the coolant was noticed in the cylinder 2 through the spark plug opening. I had changed the head gasket and noticed the slotted coolant journals between the cylinders which was clear this was where the coolant was leaking from. After replacing the cylinder head gasket it run fine for about another month before starting to have same issues of losing coolant and smoking from exhaust, coolant was observed in cylinders 2 and 3. Ford recommended replacing the engine to the new design engine that eliminated the slots, this would be at Customer cost. Engine cost was $2,618.67 in March of 2024 just to purchase the engine, i replaced the engine myself. Vehicle was at 58,735 miles but warranty was out of date.

I have a 2017 Lincoln MKZ; coolant is leaking into the engine block; have to replace the entire engine. Car has 82K miles on it. Bad thing is that my daughter's Ford Fusion (2017) had the same problem just two months. I had to replace the engine in her car. It is clear that Ford/Lincoln has this problem, Stories on the internet. Ford did issue a recall but just for the 1.5 Liter car; both of mine were 2.0 liter. These engines should be recalled - should not be happening. Daughters car just has 45K miles on it.

2017 Lincoln MKZ with 53k miles check engine light comes on and dealership diagnostic shows leaking coolant in cyl #2/needs motor. Car out of warranty so cost of repair is out of my pocket. Lincoln has known about this since 2016...they leased the car out in 2017 and then sold it to me in 2019 KNOWING there was a defective engine in the vehicle but didn't do or say anything about it...NEVER any recall. How is it that there are 100k 2021-2022 trucks and suv's being recalled due to engine issue that could "lead to catastrophic engine damage resulting in a loss of power". I could of suffered a loss of power as well with the defective engine that was in my car. How is this sudden recall on these trucks and suv's any more important or severe than all of the Ford/Lincoln vehicles that had engine issues? This could have been easily rectified early on seeing they knew about this issue from the beginning. I want my money back I paid to get my engine repaired.

I took my 2017 Lincoln MKZ vehicle into my local Lincoln dealership on the morning of 8/13 due to check engine light which came on the previous week. The results of the diagnostic test that was performed which showed P0303 coolant leaking in cylinder #2 needs motor per tsb 22-2229 at a cost $7103.60 plus tax. My 2017 MKZ with 53k miles needs a new motor…how is this??? This issue is a result of a “known” defect in the motors of certain Lincoln and Ford vehicles where coolant seeping into the engine. I call the Lincoln Care/Customer Relations Center department to advise of my situation and the representative I spoke took my information Vin #, address, phone number and said she would call me back once she has looked in what resources or programs available that could possibly assist me with this very expensive repair. She calls me back and advises that because my vehicle is out of the warranty period there is no assistance or resources available to assist me. Now, if my vehicle was still under warranty I would be covered and I wouldn’t need assistance because it would be a covered repair. So, if this is the Lincoln Care /Customer Relations Center that “supposedly” have resources to assist customers in situations such as this, who are you assisting??? not the customer under warranty because they don’t need the assistance and obviously not the customer (myself) that need the assistance but can't get any.

Vehicle just started running rough and then the check engine light came on and almost immediately temperature indicated excessive heat. I looked in the rear view mirror and noticed excessive white smoke coming out of the tail pipes. I stopped the vehicle and opened the hood and notice there was no coolant in the reservoir. I had the vehicle towed to the Ford Dealer in Spring Hill, Florida ($125.00). While the vehicle was at the dealership I rented a vehicle for 1 and a half months ($ 2476.72). New engine long block installed and completed on July 26, 2024 and I picked up my vehicle after I paid. ($7786.12).

Scared me because at first I had no idea what the heck happened. Even the guy who towed my car to dealership told me he had never seen that before. The guy in the service department said the same thing. Something caused my sunroof to shatter and it wasn’t because it was hit by something.

In February of 2024, my check engine light came on. I took it to a dealership who informed that it was a spark plug issue and that they had replaced it. The check engine light came on again fairly soon after, and before I could get it back to the dealership the car died. I had it towed there and was told that the battery needed to be replaced. The day after I got my car back, the light came back on again. After taking it back to the dealership, it was determined to be an engine issue, with coolant leaking everywhere (which is what ruined the spark plug and battery.) The estimate to fix this issue is $6,550.00. My Lincoln MKZ has approximately 60,000 miles and one owner who took care of the maintenance religiously - this should not be happening.

The 2017 MKZ has an oil leak. I was informed during a recent state inspection and oil changed. When I left to take the car in, I noticed about a fist size spot of oil on the garage floor. When I received the call from the dealership, my MKZ was serviced. The oil leak was from the oil pan. I was also, informed it required TSB. Explained by the Ford Team Leader, it did not only need a new gasket. The service for the oil leak required the following; New oil pan, new valve covers, new gaskets, etc. Lincoln has designed a NEW pan, valve cover, gaskets which should eliminate the oil pan leak. The total repair cost went into approximately 4 TIMES the cost for a normal oil pan gasket replacement. In researching, it appears Lincoln has known of the potential problem since 2015 and I purchase this as a new used. When I purchased the car, it was a bought back and I was told all issues were repaired, but it appears if this was an issue in 2015 and Lincoln has designed new parts, why was the oil pan and covers not replaced, if this engine has a known history of oil leaking. There not a recall or some type of resolution for the repair after any warranty issues. This is a design and manufacturing fault and negligence on Lincoln. Now this extreme high-cost repair is placed on the consumer to fix Lincoln's known engine design issue to eliminate the oil leak. Either a recall should have been called or the repair should not be fully on the owner. Now I am beginning to smell oil after just short

Coolant leaked into cylinders causing my engine to regularly overheat, forcing me to replace the engine at about 78,000 miles. Although I didn't realize it at the time, the first indication of a problem was at 72,737 miles (just 2,737 miles out of warranty), which is when I had the first overheating incident. According to my research, Ford has known about this problem for many years, and it affects many models over many model years, but they have yet to address the problem with the public.

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 th

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.

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.

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.

NHTSA publishes every complaint as the owner wrote it and investigates only a fraction. Spelling, capitalisation and judgement are the filer’s own.
