2017 Lincoln Mkc

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. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

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.
