2018 Ford Escape engine problems

“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.”

“This is in relation to the coolant intrusion problem with all the Ford Ecoboost engines. The vehicle has 98,958 miles - all recommended services were done. Mechanic is recommending a full engine replacement to the tune of $19000. That is nearly 2/3 the value of the car when purchased. Ford not standing behind their products has gotten to a point of hilarity.”

“The vehicle is experiencing ongoing coolant loss with no visible external leak. The coolant level drops consistently and requires frequent refilling. The issue began around mid‑mileage and has continued to worsen. The engine sometimes emits a coolant smell, and the temperature gauge rises more quickly than normal. Warning messages about high engine temperature have appeared during driving. The dealer inspected the vehicle but could not find an external leak and stated the condition was normal, even though the coolant continues to disappear. No repairs have resolved the issue. Based on known problems with EcoBoost engines, an internal coolant leak or cylinder head defect is suspected, but the exact cause is UNKNOWN. This creates a safety risk because sudden overheating can occur while driving, which may lead to engine failure, loss of power, or stalling in traffic. The issue is ongoing and the vehicle is available for inspection upon request.”

“21N12 Coolant Intrusion \ At dealership coolant in oil, coolant in firing cylinders possible explosion fire. Engine light popped on 2 weeks ago and they have my vehicle now and still do not know if they will fix it.”

“There have been several issues that cause safety concerns with my 2018 Ford Escape 1.5L Ecoboost. The two most concerning are the headlights and engine failure. Since I drove this vehicle off the lot in 2023 I have had to replace the headlights every 4 to 6 months. I recently learned it is do to an electrical issue and the most recent occurrence caused a small fire under the hood of my vehicle. Sometimes both lights would go out at once without warning. This issue has been reported by numerous consumers and Ford has done nothing. Regarding the engine failure, a coolant leak was reported by two mechanics but the source of the leak couldn't be identified. It was only discovered it was internal when my vehicle just stopped while pulling forward in a drive through. Luckily it wasn't on the highway but if it had been it could've caused an accident, at 70 mph, that likely would've resulted in minor injuries for not only me but other drivers. Ford has been made aware of this issue by owners of 2013-2019 Ford Escape Ecoboost vehicles but still hasn't issued a recall. Ford refuses to do anything about this and has instructed its customer support team to tell consumers…”

“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…”
