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.

My daughter was driving our 2018 Ford Escape at highway speed when it suddenly began shaking and shuddering violently, with no advance warning. The check engine light came on for the first time as the shaking began. The vehicle lost propulsion, and the shaking impaired her ability to control it, creating an immediate safety emergency in moving highway traffic. She had to maneuver quickly out of traffic onto a narrow shoulder. It was dark, and the limited shoulder space made exiting safely difficult. She feared for her life due to the sudden failure and exposure to passing traffic. She reached the shoulder without a collision. The vehicle required an emergency tow through her insurance company, and she received transportation home. The vehicle had undergone a safety inspection in August before this incident. A Ford dealership confirmed an internal engine leak allowing coolant into a cylinder's combustion chamber. A borescope inspection found liquid on top of the piston, and a cooling-system pressure test confirmed coolant entering the combustion chamber. The spark plugs were severely carbon-fouled, causing a misfire. Replacing them temporarily improved the symptoms, but the misfire quickly returned. The dealership determined that the engine requires a rebuild or replacement. The diagnosis appears to correspond to Ford Customer Satisfaction Program 21N12, dated June 9, 2022. We were not notified of this issue before the incident and found no corresponding safety recall for this vehicle in the federal safety agency's records. This sudden failure caused loss of propulsion and impaired control at highway speed, forcing an emergency maneuver onto a narrow shoulder after dark. The check engine light provided no advance warning. We request that the federal safety agency investigate this defect and determine whether a safety recall is warranted to prevent similar incidents and injuries.

On approximately September 28, 2026, the vehicle began sputtering when first turned on. It then progressed to running extremely rough. On September 30, 2026 the Engine Icon lit up first. A few days later, I received an Engine Fault Service Now message. I went to the Auto Zone on October 4, 2026 and they ran a diagnostic check. These are the codes that were found: Check Engine Fail Replace Ignition Coil and Spark Plug #3 P0303 Cylinder 3 misfire detected P0339 Crankshaft Position Sensor A Circuit Intermittent P0300 Random misfire detected Cylinder 3 On October 5, 2026, I took it to my mechanic and he began checking everything. He found oil on and inside the computer. He also found that there was antifreeze residue on the Cylinder and Spark Plugs. He did some research to find out what could cause this to happen. He found the following: 1,134–1,711 engine complaints depending on dataset. Failures typically occur between 50,000 and 100,000 miles. Main Engine Problems 1. Coolant Intrusion (1.5L EcoBoost – Most Common & Severe) Coolant leaks past the block/head sealing surface into cylinders. Not a head gasket failure—requires short-block or long-block replacement. Symptoms: Misfire codes (P0300–P0304) White exhaust smoke Unexplained coolant loss Rough idle, stalling, overheating. 2. Cracked Engine Block Often the end result of prolonged coolant intrusion. Leads to catastrophic engine failure requiring full replacement. On Friday, October 9, 2026, I drove my car to work, approximately 2.5 miles, after the Escape sitting for 3.5 hours, I started it. I immediately received the HIGH ENGINE TEMPERATURE STOP SAFELY, and the engine shut off. On the 3rd try, the Escape stayed running. I could only drive 11 mph. On my final turn onto a busy street, the Escape began sputtering and would not accelerate at all. I was stuck in the middle of the street, putting myself at risk of being hit. I finally made it to a parking lot but had to be pushed home by my son.

Engine light came on so took vehicle to auto repair shop. They diagnosed coolant intrusion into the engine, and told me this is a known problem. Ford has issued technical service bulletin 22-2134, as well as other documentation on the problem. It is both a functional and safety hazard. There is a class action suit (Miller vs. Ford) on this matter currently. I took the vehicle to a Ford dealer and they said there is no program from Ford to cover this known problem. I have 73,000 miles on my car! Yes, it is 8 years old, but that should not degate action from Ford on this. They have never notified Ford customers, and yet this is a safety hazard (can cause enginer to seize and start a fire). I was quoted $15,000 cost to replace the enginer from the dealer. I cannot afford this, but am afraid to drive my car!

Failed Component/System: The engine assembly/engine cooling system. The internal structural failure of the cylinder block (open-deck design defect) allowing engine coolant intrusion into combustion chambers, cylinders 2/3. Safety: The vehicle is experiencing severe engine stalling, immediate loss of motive power on active roadways, dense white smoke from exhaust which blinds trailing traffic. This causes immediate risk for rear-end collision, leaves others with the possibility to be stranded on dangerous traffic situations. The vehicle leaks hot fluids into the combustions system putting everyone at risk for under hood fires. Has the Problem been confirmed: Yes, my vehicle is currently at the Pennyrile Ford Dealership, they performed a cooling system pressure test and borescope inspection, and confirmed internal coolant intrusion requiring a total engine replacement. They have even confirmed and acknowledged that this is an on going issue! Dealer inspection: Yes Warning Lamps/Messages: Check engine soon light, raised engine levels, rapidly depleting coolant within days of refill, rough idling, cold start rumblings, sweet chemical smell and thick white smoke coming from tailpipe. Ford has already admitted this is an ongoing issue with these systems, I currently have a 2.0 engine but the recall is for the 1.0/1.5.

Ford Motor Company knew of this design flaw as early as 2010 but continued manufacturing and selling the cars with this flaw. Engine light came on but only after the engine was already compromised. Car was towed to Clay Cooley Ford Dealer in Arlington Texas on 09/23/26 who confirmed this diagnosis. My safety and safety of others was at risk because the car stopped running while I was in traffic with no warning, and it could have caused a fire.

The engine began misfiring and causing the car to shake and causing an engine light on ignition, pulling an error code of P0304, pointing to an issue with the cylinders. Even after replacing all spark plugs and coils, the engine continued to misfire and cause the car to shake. When we brought it back to our independent mechanic, he diagnosed it as a coolant intrusion, which I've come to read is incredibly common on this type of engine from Ford. The engine has failed and will need a full replacement due to the coolant intrusion into the cylinders. With this issue occurring during a long drive, it put our safety at risk. The problem was confirmed by the independent service center. The vehicle has not been inspected by the manufacturer or police, just the mechanic. The warning signs that appeared were the shaking and engine light, though they did not point directly to the coolant intrusion, as those issues are often caused by things like spark plugs as well. The issue started occuring a week before it was finally diagnosed with the coolant intrusion.

At approximately 64,500 miles, my Ford Escape was diagnosed by a Ford dealership with coolant intrusion into 3 of 4 cylinders. At the time of diagnosis, the vehicle was still driveable, but the diagnosis indicated a serious internal engine problem with the potential to cause sudden engine damage or failure. Prior to diagnosis, I noticed the coolant level repeatedly dropping for over one year without an obvious external leak, no other symptoms, and no check engine light. I first noticed the issue during an oil change, when a mechanic pointed out that my coolant reservoir was nearly empty and refilled and flushed the system. The coolant continued to drop afterward, and I monitored and refilled it as needed. Had I been informed of coolant intrusion and its risks, I would have been much more concerned. About a year later, my car began to shake a little. The very day the check engine light came on, I brought it to a mechanic where I spent over $2,000 on repairs related to engine symptoms, including replacement of the air oil separator/PCV-related components and spark plugs. One week after this repair, the engine light returned, and I brought the vehicle to Ford, where the underlying coolant intrusion issue was identified. I am concerned that coolant intrusion in the 1.5L EcoBoost engine may represent a safety defect because it can result in misfires, loss of power, engine malfunction, and potential engine failure while driving. This issue appears to affect multiple vehicles with this engine, and owners may not receive adequate warning before experiencing significant engine damage. In my case, the vehicle had relatively low mileage, was properly maintained, performed normally, and did not provide adequate warning that such a significant engine defect was developing. Although the vehicle was still operational when diagnosed, the recommended repair was financially impractical, and I ultimately had to sell the vehicle for scrap, resulting in a significant financial loss.
