2019 Ford Fusion Engine Problems

This vehicle is another of many that is suffering from coolant intrusion due to Fords faulty design. This 2.0 has 68 thousand miles and needs a new engine. This has been a known problem for this engine between 2013 and 2019. We were sold a new car that would be reliable for years, it’s not. Now we may be out upwards of $10,000.00 for a car we just paid off a year ago.

Dealer diagnosed coolant intrusion into cylinder 2, confirmed through a pressure test and borescope inspection. The dealer referenced TSB 19-2346.

Coolant intrusion, motor destroyed by coolant due to faulty ford design

See attached document for complaint.

Coolant leaking into cylinders on my 2019 Ford Fusion 1.5L EcoBoost—white smoke, rough idle, and wont start now. Ford's 21N12 program expired before I could get it fixed. Tons of owners report the same; it's a safety hazard.

Coolant intrusion into cylinder #2 in my 2.0L Ecoboost engine. This gives a rough engine start and a misfire code for cylinder #2 on cold starts. After warmup, the engine code is not active and misfire goes away when the coolant is burnt and sent through the exhaust. This also caused the car to overheat as the coolant was dropping to a low level. There was no indication of the low coolant level until the overheating.

Coolant intrusion in engine per a diagnostic visit my local ford dealership on 1-30-26 , on my 2019 ford fusion apparently a known issue problem on the ford fusion

Vehicle has a known Ford 2.0L EcoBoost coolant intrusion / head gasket defect per multiple complaints on different forums on recently googled searches. At approximately 126,000 miles, vehicle began losing coolant with no visible external leaks, producing white smoke on startup, rough idle/misfires, and check engine light. Vehicle also began overheating intermittently. Heating system stopped working, indicating coolant flow failure. Symptoms are consistent with internal coolant intrusion into cylinders due to head gasket failure, a widely reported defect in Ford EcoBoost engines. Issue presents a safety risk due to potential engine failure while driving, loss of power, and overheating. Vehicle requires major engine repair or replacement. This failure occurred despite regular maintenance and appears to be a premature engine defect, not wear and tear. I was recently at the dealership on December 8th with no other issues detected after they replaced a part on my car that failed that I had to pay for ( a P175B-00 ). This had nothing to do with what is going on currently, they ran tests at this dealership and did not detect anything as of December 8th. This was at a ford dealership. Tests were ran and inspected by manufacturer. Fast forward to a week ago I started having the above symptoms and this was diagnosed by family-friend auto mechanic. I have had multiple issues with this car. The transmission blew at 50 thousand miles, the sun roof leaked ( the seal for the sunroof was defective) into my prnd control shifter causing thousands of dollars in damage, a P175B-00, causing my car to not be able to park, causing chaos for weeks. I have only owned this car since December 2020. I still owe 7 thousand on this vehicle and I am at a complete loss. I really just want ford to take accountability for this make and model as it never fits the guidelines for recalls on anything. I want justice for myself and others with these multiple issues coming from ford cars.

Engine coolant intrusion in cylinders 2 and 3. This is a known issue with my particular build of car (4 cylinder 1.5L eco boost engine)

Internal coolant leak into cylinder heads causing overheating and engine failure. dealer confirmed diagnosis in writing. this matches ford TSB 19-2346, but ford refuses coverage since over 100k miles. This creates a safety hazard; vehicle overheats suddenly and can stall while driving.

Yesterday, [XXX], I was driving my vehicle on [XXX] in rural Kansas, to drop my mother off at the airport, and my [XXX] daughter was in the vehicle. My vehicle's temperature went directly to warning status, and I was no longer able to accelerate. I immediately put my hazards on and tried to make my way to the nearest exit to ensure we were in a safe position. Ford knows that coolant intrusion is possible in the engine block. While discussing with Ford today on the phone from 11:07 AM until 11:34 AM, and being escalated to a supervisor, they said that nothing could be done on their end, and advised to contact NHTSA. The safety of myself and others was at risk because of the faulty manufacturing of the engine and coolant system, which they report is part of a customer satisfaction program, but this is a major safety concern because, in the event it was not midday and there were more vehicles on the road, there could have been an accident. Ford Customer Satisfaction Program 21N12 One-time repair for vehicles included in 19B37 This is a known issue Ford recognizes through their customer satisfaction program. They are unwilling to assist, although in 2022, I was under the mileage specifications included in the customer satisfaction program.

10/2024 We noticed coolant was low. filled and kept watch. around 95,000 miles 6/2025 Just hit over 100,000 miles. engine misfire cylinder 3. brought it in, coolant was low, filled and replaced spark plug. 8/2025 engine misfire cylinder 3. brought it back in completed cleaning kit 8/2025 engine misfire cylinder 3. brought back in (2 weeks later). checked further and recommended a valve replace, and we needed to take it to a Ford dealership to replace 10/2025 brought into Ford dealership, coolant leaking into engine, need new engine. Ford will not cover. This is a safety issues as engine could cause fire, if coolant runs to low.

A check engine light came on and our mechanic ran diagnostics to find that there was antifreeze leaking. He said it could be the head gasket but we needed to take it to Ford dealership. We took it in and were told that it is indeed leaking coolant into cylinder due to a crack in the cylinder wall. I am the original owner and have kept up with all maintenance in the 6years I have owned the car. I was told that Fors is “aware” of these issues.
