Engine light came on and showed misfire in cylinder 4. Changed spark plug and engine coil. Still had engine light on and misfiring. Car drove in power safety mode. After much diagnosis and inspection, master mechanic found coolant leaking into the cylinder walls due to a faulty (poorly manufactured) head gasket. Coolant intrusion caused white exhaust smoke, damage to the engine block and risk of fire. Shop replaced head cylinder and gasket with current oem parts that appeared to be revised. Vehicle remains to drive in poor condition with 54k miles. Powertrain warranty did not cover this expense being the vehicle met the 6 year mark in March 2024.

I purchased the automobile on [XXX] with 44,175 miles. When the engine light came on recently, I took it to the Lincoln dealer here in Las Vegas, paid $205 for the computer to be assessed, and was told the problem was coolant leaking into the engine. They were not able to start any repairs at that time. I was not told what it would cost to repair or the time involved. I assumed it was an air conditioning problem. I drove it a few days and the engine light went off, only to come back on. I then took it to AAA ($177 for the diagnosis), reporting that cylinder 3 had coolant leaking. Tech found TSB 19-2172 TSB. 19-2172 is for current symptoms of misfire at start-up. It was suggested that I take it to the Lincoln dealer. While driving the car home on [XXX], the engine was missing, chugging. I was afraid it would stall. I am thankful it did not stall on the freeway and that I made it home safely. When I called the Lincoln dealer to make an appointment to take the car in for service, I was told it would take three or four weeks to get it repaired, that the engine would have to be replaced for $7,800 - $9,800, and that Lincoln Motor Company will not take any responsibility. He said there were two other vehicles in line with the same problem. Due to being afraid to drive it, I had the car towed by AAA on Monday, October 7, 2024, to the Lincoln dealer and was told the estimate to repair it would be $8,493. This is a coolant intrusion issue due to a faulty design in the engine block where the cooling channels will crack and leak coolant into the piston chambers. As gleaned from the Internet, this appears to have been an ongoing problem with this model. I've observed so far from the Internet that Lincoln Motor Company is not taking responsibility for this faulty design affecting many Lincoln owners. I am [XXX], and living on a fixed income. I had to rent a car and put up a $735 deposit. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

2018 Lincoln MXC -2.0L- 47,000 mile Need engine long block replacement Coolant leaking into cylinders

- Myrtle Beach, SC, USA

After the original 2.0L EcoBoost in my MKC Black Label failed from coolant intrusion around 37,500 miles in May 2023, the replacement engine my dealer installed also failed from coolant intrusion. This time, it failed in July 2024 after less than 5,000 miles. Like the first engine failure, the check engine light illuminated, but this time, the code I saw was P0300 random cylinder misfire. Like last time, the dealer performed a cooling system pressurization test, and the engine failed the test. They also did a borescope inspection and saw coolant leaking into cylinder three's combustion chamber. They also found rust pitting in the cylinder walls. Like last time, they replaced the $7,000+ long block. This failed replacement engine was assembled in March 2023 via the engine code information sticker, with the block part number J2GE 6006 AC, which Ford's TSB 22-2229 states technicians should use. The engine currently in my car, the second replacement, was assembled in April 2024, having the same block part number of J2GE 6006 AC as the first replacement engine assembled in March 2023. In other words, the dealer installed an engine with the same block part number as the one that failed on me in less than 5,000 miles. All three of my MKC's engines are assembled at Ford's Valencia engine plant in Spain. I'm afraid this second engine replacement will also fail, and I'll have to pay the full cost. In the less than three years I've owned this car, these engine replacements have cost $14,000+. I can't believe how many owners have experienced this coolant intrusion problem, as the 2.0L EcoBoost is used in many models. And it's not just the 2.0L; it's also other variants such as the 1.5L, 1.6L, and 2.3L. I hope Ford will do the right thing and recall these engines, or NHTSA will open an investigation and force a recall. Please help us owners, NHTSA, as there are many, many more of us out there suffering from these notorious engine problems that Ford doesn't want to deal with.

I have the 2.0L EcoBoost I-4 (assembled December 2017, engine block part number HV 206 AA) in my 2018 Lincoln MKC Black Label. The head gasket failed at 37,000 miles in May 2023, according to my Ford/Lincoln dealer. It started as intermittent misfiring/running rough with the check engine light illuminated. My scanner detected the code P0301 cylinder one misfire. My coolant reservoir tank level also gradually decreased, with no visible leakage. After waiting weeks to have my engine looked at, they confirmed that cylinder 1 was burning coolant as it failed Ford's cooling system pressurization test. A borescope test also proved that the coolant was leaking into cylinder one's combustion chamber. At this point, I've learned from many complaints online that these engines are notorious for suffering coolant intrusion even at low mileage, and Ford refuses to issue a recall despite this well-known issue that also plagues other EcoBoost I-4 variants. This well-known coolant intrusion problem affecting many Ford and Lincoln models is a costly safety issue for owners. Ford needs to do the right thing and recall these engines. I bought the car in December 2021 with 30,000 miles from a Lincoln dealer in Las Vegas, Nevada, and it was CPO, so the extended warranty covered the engine replacement (long block). Had this not been under warranty, I would have paid more than $7,000. Most owners are not fortunate like me to have a warranty cover this repair. The replacement engine in my MKC now was assembled in March 2023 via the engine code information sticker, with the block part number J2GE 6006 AC.

2.0 Ecoboost engine has coolant intrusion issues due to manufacturing defect and is causing the vehicle to be unsafe to drive

- Norristown, PA, USA

Misfire cylinder2 coolant found in combustion chamber requiring longblock engine replacement. Through investigation found that this is a widespread factory defect that Ford is well aware of. A diagnostic check was not performed on this issue during any routine service visit even though a technical service bulletin had been distributed to dealerships in 2019. The dealership and Ford customer service personnel all confirm there was nothing an owner could have done to prevent this result. An engine light came on at 37,000 miles, just 1 year outside of the warranty.

My car was recalled by Lincoln in May 2023 because a battery sensor causes the car to catch on fire anytime, on or off. I have had my car in to Lincoln 2 times since then and there are no parts to fix the recall. Lincoln says the sensors are on back order and they don't know when they will be available, no end date. My car can combust at anytime and Lincoln has no idea when they will have the part to fix it! There are 143, 000 cars in this recall and since May when Lincoln finally announced the recall, there have been no parts available to fix the recall since they made the announcement.

My check engine light went on one week ago and we received a message that my vehicle was unsafe to drive due to an engine misfire. We did not drive the vehicle, but could not take it into the dealership until today as they were backlogged and could not fit it in until today (9/13/22). I just received notice that my 2018 Lincoln MKC needs the engine block replaced due to a known issue with the 2.0 ecoboost engine leaking coolant into the engine, which can cause overheating and possible combustion. I discovered that there is a technical service bulletin noting this known issue, but there has not been a recall on the vehicle and it will now cost $7800 to replace.

Engine light came on and my LinolnWAy app told me to not drive over 45 mph because my car may start having smoke come out. I took the car to the dealership and was told that I needed a new engine because the coolant has leaked over. I was told that my car was the 5th Lincoln that came in and needed a new engine. A new engine was installed and I was told that i had just made the warranty otherwise it would have been a $9000 fix. I was without a car for a week and a half.
