2017 Lincoln Mkc

Check engine light on. Codes P0316, P0300, P0301, P0302. Technician confirmed via scope coolant intrusion on cylinder 1 and 2. Technician stated it is known issue with this engine and recommends a new engine for $16,169.92. This has been an ongoing issue for the past two years.

My husband and I own a 2017 Lincoln MKZ that was purchase new in 2018. It is equipped with the 2.0L EcoBoost engine, with approximately 69,000 miles. It has been meticulously cared for! Before the diagnosis, I noticed that when starting the vehicle and backing up, the engine would jerk slightly until I stepped on the accelerator to proceed. The check engine light then came on, which prompted me to take the vehicle to the Lincoln dealer for diagnosis. The servicing Ford/Lincoln dealer, Sugar Loaf Ford in [XXX], examined the vehicle and found coolant in a cylinder. We have been advised that the engine requires replacement. I am concerned because this appears consistent with reported coolant-intrusion problems involving the 2.0L EcoBoost engine used in certain Ford/Lincoln vehicles. A vehicle with only approximately 69,000 miles should not require complete engine replacement because coolant is entering a cylinder. We contacted Lincoln Customer Service and opened case #XXX requesting assistance. Lincoln declined our request and closed the case. Sugar Loaf Ford also contacted Lincoln on our behalf, but Lincoln again declined assistance. I am filing this complaint because I am concerned that this may be a recurring engine defect rather than normal wear. I request that NHTSA document this failure and consider it together with similar complaints involving 2017 Lincoln MKZ vehicles, particularly failures involving coolant intrusion into the cylinders and resulting engine replacement.

Coolant intrusion into number 2 cylinder requiring full engine replacement of my 2017 my 2.0l eco boost engine

Head gasket failure where engine coolant leaked internally into the engine cylinders.

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.

Check Engine Light present. Took car to Ford dealership. Formal diagnosis from Ford dealership: Coolant intrusion present causing misfires, specifically in cylinder 4. P0304 and P0316 codes present. This is a known manufacturing issue; however, Lincoln customer service refuses to acknowledge the problem even exists. Upon talking to the Ford dealership service members, they stated that this is a common issue. One of the service members stated he has already dealt with multiple vehicles with this exact problem this week alone. Having an engine (misfire, steam, etc) go out due to a manufacturing/design flaw, especially while driving on the highway, is a major safety issue. Service team instructed me to no longer drive vehicle which would cause catastrophic damage.

I am filing a formal safety complaint regarding my 2017 Lincoln MKC equipped with the 2.0L EcoBoost engine (VIN: [XXX]). The vehicle has experienced a severe, progressive engine failure caused by internal coolant intrusion into Cylinder 1, directly matching the structural design defect detailed by the manufacturer in Technical Service Bulletin TSB 22-2229. This defect allows pressurized engine coolant to continuously leak directly into the combustion cylinders while driving and during engine rest. This creates an immediate safety risk of vehicle hydro-locking during ignition, sudden mid-drive engine stalls at highway speeds due to severe misfires (Fault Code P0301), and unexpected engine overheating. The manufacturer has knowingly built these open-deck engine blocks with narrow coolant grooves prone to fracturing, creating an ongoing risk of sudden thermal failure and power loss in active traffic.

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.

Dear NHTSA Safety Defects Investigation Team, I am filing a safety complaint regarding my 2017 Lincoln MKC involving a child entrapment incident. On 05/17/2026, my vehicle locked itself while the engine was running, the key fob was inside the vehicle, and my [XXX] child was still inside the car. I was unable to gain entry to the vehicle and had to call 911/emergency responders for assistance. It took around 30 minutes from the time the vehicle got locked and for me door to be opened by the towing company sent by the 911 operator. Thankfully, the AC was turned on and my child was unharmed. The vehicle should not have allowed itself to lock under these conditions with the key present inside the cabin. This created a serious safety hazard involving a trapped child. Compounding the issue, the LincolnWay remote access system no longer functions because the vehicle’s original 3G modem became obsolete after U.S. 3G cellular shutdowns. As a result, I no longer had access to remote unlock functionality that had previously been available with this vehicle. Vehicle Information: • Year/Make/Model: 2017 Lincoln MKC • VIN: [XXX] • Approximate Mileage: [INSERT MILEAGE] • Incident Date/Time: 05/17/2026 at 4.15pm • Location: [XXX] Additional Details: • Vehicle was running at the time • Key fob was left inside the vehicle • Doors became locked unexpectedly • Child was trapped inside • 911/emergency assistance was required • LincolnWay remote services were unavailable due to obsolete 3G modem support ending I believe this issue represents a significant vehicle safety concern and request that NHTSA investigate whether similar incidents have occurred in other Ford/Lincoln vehicles equipped with these systems. The 911 call was placed around 4.15pm and I have the receipt from the Towing Service company Please let me know if any additional information or documentation is needed.

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.

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.

My vehicle started stuttering & shaking when starting. Then the check engine light came on. It was diagnosed with cylinder 2 & 3 misfire. All spark plugs & coil packs replaced. It got better for about 3 months then the problem came right back. Have replaced coil packs multiple times. Took to dealer who said cylinder misfires were caused from coolant leaking & the only fix was to have engine replaced & quoted $11000. This started at about 95000 miles. Vehicle has had perfect maintenance, all oil changes done on Schedule. Dealer said motor can lock up at any moment & this was a manufacturer error.

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.
