Id been getting misfires on cylinder 3 and eventually 2 even after replacing coilpacks, spark plugs, and fuel injectors into my 2018 ford escape sel 1.5L ecoboost engine. We believe it to be a coolant intrusion and have not been able to operate my vehicle. White smoke appears and it stutters a lot on start up.

The contact owns a 2017 Ford Escape. The contact stated that while starting the vehicle, the vehicle was shaking with the messages, " Cylinder #1 Misfire" and "Coolant Level Low" displayed. The coolant level was low. The vehicle was taken to an independent mechanic, who diagnosed a misfire in cylinder #1, replaced the spark plugs, and added coolant; however, the coolant level was low within the week and coolant was added. The vehicle was taken to the dealer, who determined that the engine needed to be replaced. The manufacturer was notified of the failure by phone and informed the contact that the vehicle was out of warranty. The failure mileage was 93,692.

We've been having check engine light on "Cylinder 2 misfire". We had the spark plugs replaced and the ignition coil replaced, which fixed it for about a month, but it returned. We had further diagnostics done with video into cylinder 2 and found that we have engine coolant leaking into the cylinder. Apparently, this is a known, unrecalled issue from Ford on this engine with the coolant intrusion. Only fix is to replace the motor. Car has about 120,000 miles on it, but well taken care of. Works great otherwise, but with this issue, the engine could lock up or catch on fire on the road.

Was sold a 2016 ford escape that apparently has a known coolant leak issue that is caused by a bad engine block. When I bought the car in 2021 I had to wait two weeks to get the car so they could fix a cylinder misfire issue. Had several issues with it overheating and was told that it just needed coolant added. In 2026 was told that the head gaskets was blown and to repair would cost $9000 at the same ford dealership where I bought it. I had another Authorized NAPA Garage replace the head gaskets for $5000 and with in a week had misfire on cylinder #4 again while on the freeway doing 55 MPH which caused the car to stall on the freeway in traffic! Started investigating the issues to find out that it is a well documented issue with 2016 fords having a bad engine and the only fix is replacement of the engine!

I suffered catastrophic engine misfires with a sudden loss of power and white smoke coming from the exhaust. This was due to a design flaw in the Ford ecoboost 1.5l engine which allowed coolant into the #3 cylinder.

My vehicle was traveling okay back in the beginning of June 2026. While driving down the road with my children in the car the vehicle started throwing several codes out of no where. The codes were pre-collision assist not available, Service Advance Trac, Park Break fault service now. I took it to O'reileys after calling the Ford Dealership that (at the time) was local and that was their recommendation. I had the car scanned and it recorded a first cylinder misfire. We had to disconnect the battery and jump the car to get it to start. I brought the car to the Ford Dealership I baught the car from on June 12th where they kept the car for a week returning it on the 18th and stated they reprogrammed the gateway module. A week and a day later I had the same issue arise but with MORE codes, not starting without jumping, stalling while driving. the dealership had my car from 07/06/2026 - 07/27/2026 and replaced and reporgrammed the new gateway module. I made it 45 minutes from the dealership when the car started throwing even more codes including powertrain codes, parking brake codes. Endangering the lives of me and my children. The dealership came and got the car 7/29 via private tow and checked it in 7/30. They kept my car until 10/22 due to numerous codes, safety concerns. Stated they replaced the wiring harness, all modules, tested the wires one by one, applied a pigtail from the wiring harness to the PCM. Yesterday 10/27, five day after ford had my car for 85 days and we are throwing all the codes YET AGAIN for a 4th time but now umongst the stalling and the codes and the braking concerns we are also now having power steering concerns. This has now endagered the lives of me my husband and my children under numerous occasions. Ford has had my car a total of 112 days in the last 5 months 85 of them concecutively. We have even contacted Ford Motor Company and BBB Auto Line and were told there is nothing anyone can do due to it being out of premesis or over mileage.

1. The EcoBoost engine block suffered a severe structural failure caused by a factory manufacturing defect known as internal cylinder block coolant intrusion (as documented in Ford TSB 19-2208). Antifreeze leaks directly past the cylinder wall block grooves into the combustion chambers. This vehicle is currently parked and is fully available for physical inspection upon request at the location provided. 2. The engine suffered a sudden, severe mechanical malfunction while driving, causing an immediate drop in cylinder compression, engine misfires, and a dangerous loss of control and motive power. Driving a vehicle prone to sudden stall or failure creates an extreme hazard on public roads, dramatically increasing the risk of a high-speed rear-end collision or stranding the driver in live traffic without propulsion. 3. Yes. The vehicle’s loss of coolant, engine misfire codes, and cylinder block leak characteristics were physically inspected and confirmed by a private, independent auto mechanic. 4. The vehicle has not been inspected by the police or insurance as no crash has occurred yet. Ford Motor Company's customer service and Tier 2 Automotive Consumer Operations (ACO) divisions have been formally notified of the defect, and corporate Case File #CXH-0934-5907 was opened. However, a physical dealership inspection has not been completed due to the manufacturer's refusal to waive upfront diagnostic fees for an out-of-warranty vehicle. 5. Prior to total engine failure, the vehicle displayed an aggressive engine overheat warning indicator on the dashboard. The reservoir was found entirely stripped of coolant, with no visible external fluid leaks underneath the vehicle. These active symptoms and high engine temperature alerts first appeared suddenly on the dashboard on the day of the breakdown.

Apparently my 2018 Ford Escape 1.5 liter Ecoboost engine has a known flaw of coolant intrusion into the cylinders. It can be inspected right now as it's at the Ford service center. This problem could have left me on the side of the freeway at night. Ford service has verified the problem and that it needs a new engine. I dont believe the parts have been inspected by anyone other than Ford service and my independent mechanic. There was a check engine light that came on back in April of this year. I brought it into Ford for basic minor service on April 29 and was told to check diagnostics I had to pay $298. I took it elsewhere and they told me it was a code that came up for the smog system. I didn't have any other issues at that time. In July a different light came on that was flashing so I took it to an independent mechanic and he found the misfire code of P0304 in cylinder #4. He proceeded to replace spark plugs and injector #4. Not until September did the sputtering start but no engine light came on. I took it back to my mechanic and he spent 2 weeks trying different things to figure out what was going on. He was unable to so I had to take it to the Ford service center and they verified the coolant intrusion problem. My car is only 8 years old and there was never a recall or service notice to advise me of this problem.
