My 2017 Lincoln MKZ with only 52100 miles started leaking coolant into the engine cylinders which will require a new engine. Ford/Lincoln is aware of this problem with their 2.0 liter Ecoboost engine and has even issued a service bulletin and the necessary engine replacement. I have contacted Lincoln Customer Service and their response was they have no liability since the vehicle is out of warranty. I have noted there are several class action lawsuits in progress and I believe a recall has been issued on some Ford/Lincoln Ecoboost engines. A recall should be issued for all affected engines and not just some models. Thank you for your attention in this matter. The engine replacement will cost at least 7000. Ford should be responsible for reimbursing my out of pocket costs as a result of their unwillingness to resolve this issue.

I purchased a 2017 Lincoln MKZ and began experiencing serious engine problems, including repeated overheating and an engine misfire. The vehicle developed a check-engine light and a P0301 misfire code. I was advised by a repair shop that the vehicle has a serious engine problem and that the engine needs to be replaced. I am concerned that the overheating and engine problems could cause the vehicle to suddenly lose power or suffer complete engine failure while I am driving. If the engine loses power unexpectedly while I am traveling in traffic, I could be unable to accelerate or safely move out of the way of other vehicles, creating a serious safety hazard for me, my passengers, and other motorists. I contacted Lincoln regarding these problems and asked the manufacturer for assistance, but Lincoln refused to provide assistance with the issue. I am now left responsible for addressing a potentially serious engine and safety problem. I am requesting that NHTSA document and investigate these engine, misfire, and overheating problems to determine whether they may be related to a safety defect affecting other 2017 Lincoln MKZ vehicles.

We are submitting this vehicle safety complaint regarding a dealer-confirmed coolant-intrusion failure in our 2017 Lincoln MKZ equipped with the 2.0L EcoBoost engine. The vehicle had approximately 60,063 miles when presented to Parks Lincoln of Longwood. The vehicle developed a check engine light, rough running, shaking, and recurring misfire symptoms. Two ignition coils had recently been replaced, but the symptoms returned. The vehicle also produced white exhaust smoke on startup after sitting for several days. Because the rough running was so severe, the vehicle was ultimately towed to the Lincoln dealership on a flatbed. Parks Lincoln's Repair Order 2684839/1 documents DTC P0301. The technician states that, pursuant to TSB 22-2229, a coolant pressure test and cylinder inspection were performed; coolant intrusion was found in cylinder 1; and a long-block engine is required to properly repair the concern. Lincoln TSB 22-2229, NHTSA Manufacturer Communication No. 10214126, describes coolant intrusion in certain 2.0L EcoBoost vehicles including 2017-2019 Lincoln MKZ models. The bulletin identifies white exhaust smoke, rough running, and misfire codes, including P0301, and directs replacement of the long-block engine assembly when the condition is confirmed. Our safety concern is that coolant intrusion can progress from rough running and misfire to loss of engine performance or engine failure while the vehicle is in operation. In our case, the symptoms became severe enough that we did not consider continued driving appropriate and had the vehicle transported to the dealer. We ask NHTSA to add this complaint to its defect database and evaluate it together with other reports involving 2.0L EcoBoost coolant intrusion, misfire, loss of power and engine failure. We can provide the complete dealer repair order, estimate and additional records upon request.

I am reporting a catastrophic engine failure and engine-compartment fire involving my 2017 Lincoln MKZ Select, equipped with a 2.0L EcoBoost engine, VIN [XXX]. The vehicle had approximately 99,864 miles when the final failure occurred. Shortly after I purchased the vehicle, the original engine developed severe overheating, loss of cabin heat, white exhaust smoke, misfiring, and coolant intrusion. On December 16, 2024, at approximately 95,354 miles, the vehicle was taken to Murgado Ford Lincoln of Chicago. The dealership documented diagnostic codes P0303 and P0316 and determined that coolant was entering cylinder No. 3. Pursuant to Ford Technical Service Bulletin 22-2229, the dealership replaced the long-block engine and related one-time-use components. The replacement service-engine assembly was identified on the repair invoice as part No. J2GZ-6006-E. The vehicle was returned to me on approximately January 30, 2025. After the engine replacement, the vehicle continued to experience serious problems. Within days, it stalled in an intersection, produced white smoke, lost cabin heat, and had to be returned to the dealership. The vehicle later continued to exhibit hesitation, harsh shifting, loss of power, and other abnormal drivability symptoms. On September 4, 2025, while I was operating the vehicle under normal driving conditions in Chicago, I heard a sudden loud metallic grinding or mechanical noise coming from the engine area. Gray smoke then began coming from the vehicle and quickly progressed into heavy dark smoke. A fire developed in the engine compartment, forcing me to stop and exit the vehicle. The fire rapidly intensified and was followed by an explosion or explosive sound. There was no collision that initiated this incident. The vehicle sustained catastrophic fire damage and was rendered a total loss. The failure occurred only approximately seven months after the replacement long-block engine was installed and after I had repeatedly experien INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Coolant intrusion with eco boost engine.

ENGINE — Filed 02/10/2026

I own a 2017 Lincoln MKZ equipped with the 2.0L EcoBoost engine. At approximately [MILEAGE] miles, the vehicle began experiencing loss of coolant, rough running/misfire, shaking/rough start, and reduced engine performance. The vehicle was diagnosed by a Ford/Lincoln dealership as having coolant intrusion into the engine/cylinders and/or engine block failure, requiring engine/long-block replacement. The estimated repair cost was approximately $8000. This creates a safety concern because coolant intrusion can cause misfires, overheating, engine damage, and possible loss of power while driving. Ford/Lincoln has issued Technical Service Bulletin 19-2346 and superseding bulletin 22-2229 for 2017–2019 Lincoln MKZ vehicles equipped with the 2.0L EcoBoost engine. These bulletins describe low coolant, white exhaust smoke, rough running, misfire codes, overheating codes, and coolant intrusion into the cylinder, with the prescribed repair being long-block engine replacement. Despite this known documented condition, Lincoln/Ford denied assistance because the vehicle is outside warranty. I am reporting this as a potential safety defect because the failure can occur without adequate warning and may cause engine overheating, misfire, or loss of power while the vehicle is being operated.

Took car into Ford dealership service because the check engine light came on. The car was sounding a little rough also. When they called me, I was expecting a tune up or just a sensor issue, but I was told that I needed a new engine! The tech found dtc P0302 for misfire on cylinder number 2, found coolant on spark plug. Cylinder #2 was cracked and leaking coolant into it. Was told it would lead to catastrophic failure. Was told I needed a long block replacement at the tune of $9,000. The service tech called Ford to help with the costs, but since I didn't have an extended warranty, they wouldn't do anything. The car has been barely driven and taken well care of. I bought it in 2019 with 12k miles and now in 2026 it only has 69k miles. I have researched and found out that this is a systemic issue. Had I not replaced the engine it could of been catastrophic! I have been with Ford since I started driving in the early 80's. This is unacceptable. According to several reports, this has been reported many times (maybe thousands?). I wonder how many are NOT reported. Ford needs to reimburse for the defective engine.

ELECTRICAL SYSTEM,VEHICLE SPEED CONTROL — Filed 05/01/2026

2017 Lincoln MKZ was taken to Community Ford Lincoln of Bloomington (Auto Vest II LLC), Bloomington, IN for service on 05/01/2026. No ABS, Traction Control, or AdvanceTrac warning lights were present at drop-off. After the vehicle was returned, all three warning lights were illuminated. The ABS/stability control system had been damaged during the service visit. Diagnostic codes C0031:07 and C0031:15 (left front wheel speed sensor circuit fault) were confirmed in writing by the dealership service manager on 06/09/2026. The dealership denied responsibility. An independent Ford/Lincoln dealer (Tom Roush Lincoln) estimated repair at $310. The servicing dealer offered only partial reimbursement of $169.45. The ABS and stability control systems are safety-critical. Their failure compromises emergency braking performance and vehicle stability, putting driver and other road users at risk. The vehicle has been unavailable for normal use since [XXX]. The problem was confirmed by an independent Lincoln dealership. The vehicle is available for inspection.

I am submitting this complaint to report a serious vehicle safety incident involving my 2017 Lincoln MKZ Select that resulted in a catastrophic engine fire while the vehicle was in operation. Prior to the incident, the vehicle underwent a long block engine replacement performed by Murgado Ford Lincoln of Chicago pursuant to Ford Technical Service Bulletin (TSB) 22-2229. The repair involved removal and replacement of the engine assembly and related components. After the vehicle was returned to me following this repair, the engine later experienced a sudden catastrophic mechanical failure while I was driving. The vehicle rapidly began emitting smoke from the engine compartment and subsequently caught fire. The fire escalated quickly and rendered the vehicle a total loss. At the time of the incident, the vehicle was being operated under normal driving conditions. There was no collision or external cause that would have triggered the fire. The event appears to have originated within the engine compartment following the recent engine replacement. The vehicle was subsequently towed and is currently stored at City of Chicago Auto Pound No. 6 following the fire incident. The vehicle has not been repaired or altered since the event and remains available for inspection. Given that this vehicle had recently undergone a major engine replacement under a manufacturer technical service bulletin, I believe the circumstances warrant review to determine whether the incident may be related to: a defect in the replacement engine assembly improper installation of the engine or related components fuel, oil, or electrical system issues associated with the repair. This incident presented a serious safety risk to the driver and could have resulted in severe injury or loss of life. I was fortunate to escape the vehicle safely before the fire fully developed. I am submitting this complaint so that NHTSA may evaluate whether this type of failure represents a broader safety concern.

So I bought this car in February of last year. Since I've had it june I had to do a head gasket. Another time the high speed fuel pump had bolt come loose and oil went everywhere causing a fire. Had transmission intercooler line do the same thing. Additional fire. And just recently I problem that was supposedly fixed already wasn't and flywheel broke leaving me stranding in a parking lot for 4 days dropping transmission. The dealer didn't put back all the parts correctly either.

Incident Summary – Vehicle Fire Date of Incident: Thursday, September 4, 2025 Context: I was driving to a scheduled service appointment for my car at Murgado Lincoln Dealership of Chicago Events Leading Up to the Fire While driving, I heard loud metal noises coming from under the hood. The sound was either metal pieces falling off or grinding/chomping metal against metal. Concerned by the noises, I pulled over to the side of the road. Smoke and Fire Once stopped, the car began emitting gray smoke, which quickly turned into black smoke. The black smoke entered through the dashboard, filling the interior cabin. I realized the vehicle had caught on fire. Immediate Actions Taken I quickly gathered personal belongings from inside the car. I was lucky to have evacuated the vehicle immediately to ensure my safety, despite inhalation of potentially hazardous chemicals due to the fire/ plastic of the car. I then called 911 to report the fire and request emergency assistance. The car continued to catch fire and then there was a minor explosion, as the Chicago fire department battled the fire.

I purchased a 2017 Lincoln MKZ Select which has been a continuous source of mechanical problems. After recently having a new engine installed, the vehicle has now developed significant transmission issues, making it unsafe and difficult to drive. Despite being sold this car under the assumption it was reliable, I am struggling with costly repairs and reduced functionality, effectively driving a “lemon.” I believe the vehicle’s condition and recurring failures qualify it for protection under consumer lemon laws or warranties, and I am seeking resolution or compensation due to these defects that have severely impacted the vehicle’s usability and my safety.

I purchased my 2017 Lincoln MKZ Select on November 11, 2024. The vehicle was determined to need a new engine, per Murgado Lincoln of Chicago. They had my car for over 48 days while putting in a new engine. After this was completed the car had to be sent back due to a mistake the mechanics made by not attaching a gasket properly. After this, I began experiencing odd noises underneath the hood and throughout the vehicle; delayed timing belt in both acceleration and deceleration, and so forth. I was then involved in a hit-and-run car accident (not my fault). All side airbags deployed and my passenger side rear wheel is destroyed. I had this car assessed just a few days ago by a certified Auto Care Company who said I needed a completely new transmission and that this car is not street legal at the moment... insurance is not helping me at all.

I purchased this vehicle on November 11, 2024. About one month later, I began experiencing severe problems. The engine started overheating, which marked the beginning of a downward spiral of issues. To address the overheating, a new engine was installed by Murgado Lincoln dealership, which took approximately 48 days to complete. While the new engine resolved the overheating, a serious transmission problem has persisted and worsened. Since I purchased the car, the transmission has been slipping constantly, shifting gears on its own unpredictably, making loud noises under the hood and throughout the entire vehicle. These issues create a major safety hazard, putting me and others at significant risk. On June 25, 2025, I was involved in a hit-and-run incident that likely worsened the vehicle’s condition. During this incident, the side airbags on both sides of my vehicle deployed, but the front airbag did not deploy at all, which is highly concerning and increased the danger during the impact. Additionally, the car has a cracked shock absorber head, likely from the accident, which has led to instability and potential fishtailing. I am now afraid to drive the vehicle due to unpredictable handling and further mechanical failure. The vehicle is available for inspection upon request. These problems have been confirmed and partially addressed by the dealer when the engine was replaced, but the transmission issues have never been fully resolved. There were no specific warning lamps for the transmission before the failure, but the slipping and erratic gear changes started about one month after purchase and have become progressively worse.

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.

2017 Lincoln MKZ had the "Auto Hold" on and the car came to a complete stop at an intersection with a red traffic light. One other vehicle was in front of me and we had been stopped for at least 30 seconds. Without notice the Lincoln MKZ quickly lunged forward and struck the vehicle in front of me. I kept applying the brake but the car would not stop, it kept hitting the car in front 3 times before it stopped. Auto Hold button was still illuminated. The car was then turned off. The person in the car in front of me stated that they thought I was hit from behind and pushed into their car. I also thought that I was hit from behind and pushed into the car in front. There were no injuries. If I would have been the first car at the light, chances are my car would have been T-boned. I have not driven the car since the incident. No warning signals were given prior to the incident. I would like to have the EDR , black box, evaluated to determine why the Auto Hold malfunctioned. Air bags did NOT deploy. The car is scheduled for service on January 10, 2022.
