2019 Lincoln Mkc

Engine warning light went on. Replaced spark plugs and coil to cylinder # 2. Then, Traction control light indicated system off. Technician advised the need for dealership software upgrade to ABS. Dealership advised that engine block allowing coolant intrusion into #2 cylinder. Needs a new engine. And need for a new ABS module, also defective.

Vehicle overheated, due to collant entering #1 cylinder. This coolant intrusion is apparently a well documented issue, from an acknowledged engine defect. (TSB 19-2346, TSB 22-2133) Ford dealership recommended an $11,000 + tax engine replacement, with no relief, as car is past its warranty. The vehicle has 58540 miles. Lincoln customer service also declined any goodwill repair. Independent Service Dealer (Craig’s Auto Repair Service 281-469-5949) first diagnosed the issue, recommended taking the vehicle to Ford Dealership (Tomball Ford).

The contact owns a 2019 Lincoln MKC. The contact stated that the messages "Service Advancetrac", "Hill Start Assist Not Available", "System Off - To Save Battery Please Turn Off Ignition or Start Engine" were displayed. The vehicle was taken to the dealer, where it was diagnosed, and determined that the battery and the battery monitor sensor had failed and needed to be replaced. The parts were ordered to repair the vehicle. The vehicle was not yet repaired. The contact related the failure to NHTSA Campaign Number: 23V378000 (Engine); however, the VIN was not included. The manufacturer was not notified of the failure. The failure mileage was approximately 98,000.

My 2019 Lincoln MKC with only 52,200 miles experienced unrepairable engine damage due to an internal coolant intrusion condition that directly matches Ford TSB 22-2229. On or around Jan 1st or 2nd, a check engine warning light came on as I was driving home at night. I did not drive my car any further except to the dealership for service on 1/5/2026. The engine failure was diagnosed by the dealership on 1/6/2026. This engine failure occurred well below a reasonable engine life expectancy, and is caused by a documented design defect. The manufacturer’s refusal/delay in recalling these engines with a known design defect places drivers at risk of being stranded at any time of day or night, and drivers risk becoming a road hazard to themselves and others when experiencing complete engine failure.

2019 Lincoln MKC with 96K mileage suddenly started running rough around 30mph and I was losing power as I was entering a highway on a ramp. RPM needle was fluctuating between 2K and 3K. Immediately drove back home and towed it to Lincoln shop. They said its an issue with Coolant Intrusion into the engine compartment and would have to replace the engine block. Estimated at $11K. Extended warranty company said claim is likely to be denied as these Ecoboost 2.0L engines are notorious for these issues. It is a faulty manufacturing and there is no recall. Costing consumers thousands of dollars and also putting lives of passengers at risk.

My car misfired, then the heat wouldn't work then started to overheat. The car is 2019 MKC 2.0L engine. Only 64k miles on it. I am the original owner. Took it to the dealership and they said the coolant has back up into the engine. I read that this has been a known issue with these engines and was never notified. It is going to cost 10k to replace this engine.

My initial reason I took the car to the dealership, was because the vehicle would not want to start or stay running after fuel was put in. I aIso had a check engine light on. After the dealership performed diagnostics on it, they said the purge valve was bad which was the cause of it not starting. The check engine light was on because it was low on coolant. So I scheduled another appointment with Wyatt Ford in Manistee MI 49660 on Dec 1, 2025. They performed a coolant pressure test and determined that it is losing pressure after shutdown. They cannot find a leak. They removed the spark plugs, but #3 spark plug is "stuck" and they are attempting to remove it. If the spark plug breaks, they will take more of the engine apart to access it and attempt to "tap" out the threads of it. The technician (Sherman) told me that the cause of it being stuck could be due to the fact of the coolant leaking into that cylinder. Sherman was able to remove the #3 spark plug and found coolant in that #3 cylinder. They are now saying that the engine does need replaced and it is not safe to drive. The service department (Ava) gave me Ford Customer Service number to call to start a case. I called 800-392-3673 and spoke with Alex. She told me she will do some further research and call me back in about two hours. It is now 12:30 pm east coast time. After returning a call from her, she said that there are no programs at this time with Ford to assist with replacing the engine. Only if there is a recall on this is when they would be able to replace it for us.

The 2019 Lincoln MKC model made prior to April 2019 is part of a variety of Ford/Lincoln manufactured models that are known to have a coolant intrusion issue. This causes various issues within the engine system such as head gasket failure, cracked cylinders, and cracked engine block causing the coolant to leak and potential for fire risk. Although check engine light warning will be present, the code is presented as a misfire and the suggested fix is to replace spark plugs and coils. This will be completed, and seem to resolve this issue however, it is temporary and problems continue to persist. The car will loose power while driving and be unable to accelerate or continue to keep consistent speed such as when driving on freeway. Despite having a TSB 22-2133, customers are not made publicly aware of this issue and if they do not fit within warranty timeframe the dealer will not complete recommended service of the issue. Therefore, the customer is not at fault for the unsafe, known manufacturing issue and therefore Ford/Lincoln should make the effort in correcting this prior to serious customer injury/death.
