2017 Lincoln Mkc

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)

Symptoms consistent with TSB 19-2346 for 2.0L EcoBoost engines: coolant in cylinders, white exhaust smoke and check engine light is on. I have to keep topping off the coolant weekly, engine light comes and goes with same errors. Went to a general mechanic who got error codes PO301-00 AND PO316-00. Currently scheduled next week to see an engine mechanic. Available for inspection upon request. Has not put us in danger yet but is of major concern due to potential for failure, so we are having it seen to ASAP. We don't have a Ford dealership so nearby to go out there with a failing car just to have them verify that yes that is the issue and yes it will be a very expensive repair we could not afford if we did it with them. Despite very low mileage it is still past warranty date, so any goodwill would have to come after we go through the trouble of bringing our vehicle in and hoping for the best. We called and they couldn't even provide any kind of ballpark likelyhood of goodwill.

Within 4 months, I’ve spent $12k on transmission replacement (refurb.) (Metallics in the fluid), Fuel injectors, etc. The check engine light is still on…Now Im told that coolant is leaking into my engine, and the engine needs replaced! (Coolant intrusion) Another $9k for parts and labor! i just paid the car off! Ive kept up with repairs and service! Ive done everything the dealer has suggested…except replace the engine! I’m still recovering from the cost of the transmission! The 2017 Lincoln MKC with a 2.0L EcoBoost engine has a known defect where coolant leaks into the engine cylinders, often causing misfires, overheating, or engine failure. This issue, linked to faulty engine block and cylinder head design, typically requires engine replacement ($5,000-$9,500). Ford issued TSB 22-2229 but no recall. A class-action lawsuit is ongoing. Check warranty status; report to NHTSA.

Vacuum pump, 2.3 ecoturbo charger not available for inspection. Dealer in ND replaced vacuum pump twice and car ran worse than when I brought it in so they then decided it was the turbocharger and replaced it. My check engine light and ABS light were on. Could not drive over 55 mph and was on highway when lost power and slowed way down significantly with traffic congested. Had to pull off to side. Thick Smoking from tailpipe they said oil got lnto the catalytic convertor it would eventually wear off and ok to drive. Took to different dealer and they replaced the vacuum pump again (this was the 3rd one)it has 73000 miles on it. I Drove for 20000 without trouble. Now I'm at dealership in TN and they are replacing the entire engine. Without any help from Lincoln and the car has 91000 miles on it
