2017 LINCOLN MKC Complaints

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.

None of my airbags deployed in a one vehicle accident when my tire blew. I woke up sitiing in a guard rail.and injured. This happened on September 4th, 2025. Car totaled and Travelers Insurance already paid off finance company and I was left with nothing. I have trouble walking g, a brokthumb. Constant headaches and chest soreness.

Back up camera goes black or really fuzzy so everything is unrecognizable. This happens very sporadically. It could stay like this for days or sometimes just once in a few weeks. Never know when it will happen.

I purchased a 2017 Lincoln MKC approximately 90 days ago and recently encountered a check engine light notification with the diagnostic code P303, indicating a misfire in cylinder three. After replacing the fuel injector on that cylinder and completing a tune-up, which included the replacement of all spark plugs and ignition coils, I consulted a new mechanic. They informed me of a potential issue related to engine block intrusion, which reportedly affected other 2.0 L engines from Ford Motor Company within the 2015-2019 model years. As a result, I have been advised to consider replacing the entire engine. Given that I acquired the vehicle as a used model with only 43,000 miles and is now out of warranty, I am facing an out-of-pocket expense of nearly $8,000.

Engine light came on. Took it to mechanic. Was told there is a well documented mechanical issue affecting my 2017 , MKC. My vehicle is experiencing a misfire and cylinder three accompanied by signs of colon intrusion into the engine, as well as transmission slippage. I have heard these are known and widespread issues in 2015 to 2019 Lincoln MKC models equipped with the 2.0L Eco boost engine. I am aware of several technical service bulletins, including TSB 19-2346 and TBS 22-2229, that detail this defect. Numerous Lincon customers have reported identical issues at similar mileage, often requiring full engine or transmission replacement. My trusted mechanic has verified that my vehicle exhibit symptoms consistent with this engine defect.

Coolant Intrusion into the cylinder causing overheating. New engine block required. Car has been regularly maintained. Failure occured with no warning.

I own a 2017 Lincoln MKC 2.0L EcoBoost that suffered a complete engine failure caused by coolant intrusion into the combustion chambers. The vehicle began to misfire, emit thick white smoke, lose power, and quickly became almost undriveable. Technical Service Bulletin (TSB) 19-2346 (June 2019), which describes coolant entering cylinders due to a flaw in the cylinder head/block design. This failure is not the result of neglect or normal wear and tear — my vehicle has been maintained according to manufacturer recommendations. Despite this, the engine requires complete replacement at a cost of approximately $9,500. The failure occurred well before what should be the normal service life of an engine, and it matches the same defect pattern reported by many other Lincoln and Ford owners with the 2.0L EcoBoost engine in multiple model years. The coolant intrusion defect creates a serious safety hazard because it can cause sudden, unpredictable loss of engine power while driving. If the defect manifests at highway speeds, the driver may experience immediate power loss, inability to accelerate, or complete engine shutdown — increasing the risk of a collision. Ford/Lincoln have issued internal bulletins to dealers acknowledging this problem but have not initiated a public recall. Many owners have been denied coverage due to warranty expiration, despite this being a manufacturing defect. The result is that numerous vehicles with a dangerous and well-documented engine flaw remain in circulation without corrective action. I believe this defect warrants investigation as it poses both a safety risk to drivers and passengers, and a broader consumer protection concern. Premature catastrophic engine failures on relatively low-mileage vehicles undermine public trust and place owners in severe financial hardship. An NHTSA investigation could compel Ford/Lincoln to issue a recall to address this hazard before more vehicles experience unsafe sudden failure

The Engine light periodically came on. The coolant was low, but no evidence of a leak. We took the car into be evaluated and to was identified as error code P0304 for cylinder #4. The only way to repair is a new engine. The car has 71000 miles on it. During our research it was identified that this is a known issue to Ford, but this has not been acknowledged as a defect/recall. It was recommended to immediately repair as the engine can stop or the car can lose power /control while driving. The car is no longer under warranty. There are tons of reports of this issue, and 130 reported on this site. This is a danger to those driving or if something would happen on a highway, this could cause an accident at high speeds to the other cars trying to avoid a stopped car. Dealers recommend calling to complain to Ford to attempt to get resolution. And there is a class action lawsuit.

My 2017 Lincoln MKC has engine coolant leaking in to the #4 cylinder. On start-up the engine runs rough, and the check engine light is on. LINCOLN/FORD has a Technical Service Bulletin #22-2229 covering this issue. I believe this is a common problem involving a large number of these engines. LICOLN/FORD will not pay for any replacement costs. I have spent $1414.08 in an attempt to repair this problem. I believe this also causes my car not to be able to pass the Ohio E-Check.
