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

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.

The vehicle lost power on the highway due to an overheating issue. Very dangerous when this happens while your going 70 mph. The vehicle was later determined to be a victim of Ford's known 2.0L Ecoboost engine that due to Ford's defective design, which Ford admits but refuses to issue a recall for. The ONLY fix for this problem is to have the long block replaced at a cost of over $9,000.00. Not exactly Ford looking out for the safety of their customers.

Coolent intrusion, coolent leaking into cylinder number 2 causing a misfire and excessive white smoke every time I start the vehicle, seems this is a manufacturing flaw from the research I've done with so many other people having the same complaints because the engine block is the cause of the problem the way they designed it ford acknowledged the problem saying it's the engine block because of a poor design only way to fix this is with a new redesigned engine block and that cost a lot of money I think Ford should be held accountable and should do a recalls on these and get these fixed this is not right.

Fire reported
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.

The car has been experiencing a persistent cylinder #2 misfire. We replaced the coils and spark plugs, only to learn that this is a common issue with the 2.0 MKZ engines. The problem has worsened to the point where the car sometimes can barely move in traffic, creating a serious safety risk if other drivers don’t notice the vehicle slowing to a crawl. It also puts my family at risk if we ever have to exit the car in busy traffic. Ford has diagnosed the issue, but they stated there is no recall associated with this VIN. The check engine light remains on.

My 2017 Lincoln MKZ experienced a sudden and severe engine failure consistent with the known Ford/Lincoln coolant intrusion defect affecting 1.5L, 1.6L, and 2.0L EcoBoost engines. While driving, the vehicle began losing coolant with no visible external leak, followed by rough running, misfires, and complete engine shutdown. The vehicle became inoperable and had to be towed to a Ford dealership. At the dealership, technicians were unable to start the vehicle at all, and could not even pull it into the service bay to perform diagnostics. The service department told us the symptoms match the known coolant‑intrusion issue documented in Ford’s Technical Service Bulletin 19‑2346, which applies to 2017–2019 2.0L EcoBoost engines. They advised us not to pay for diagnostic testing, because the failure pattern is already known and documented by Ford, but not covered under any recall. They referred us to Lincoln corporate. Lincoln corporate then informed us that they have no programs available to assist with this defect, even though it is a known issue. They stated that even if a program existed, they “wouldn’t be able to assist with even half the cost.” They also suggested that we consider installing a junkyard engine as a more cost‑effective option. This was their only recommendation for a catastrophic engine failure caused by a known defect. This is extremely concerning for a safety‑related failure. The symptoms match Ford’s documented defect exactly: • Coolant loss with no external leak • White smoke prior to failure • Engine misfires and rough running • Overheating • Engine unable to start • Potential for engine seizure or fire This is the same failure pattern described in recall 25V685 and the January 2026 recall, which involve coolant intrusion, overheating, and fire risk in similar Ford/Lincoln engines. My VIN is not included, but the failure mode is identical. My vehicle is now completely disabled due to this defect, and Lincoln has refused any assistance.

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.

Crash reported
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.
