The check engine light came on. Took the car for service. The mechanic did many diagnostic tests and discovered coolant leaking into the cylinder. Advised this caused engine failure and is unsafe. The engine must be replaced. The manufacturer is aware of this problem and the unsafe driving conditions it causes. They have issued a technical service bulletin but not a recall.

Check engine light displayed despite the fact that the car seemed to be running fine. I took the car to a repair shop and then to Ford Service who documented the diagnostic code P0302 Misfire4 on Cylinder #2. They did a pressure test. and found coolantintrusion on cylinder #2. The recommended repair was to replace the engine at a cost of $8700. My Ford EDGE has only 61,000 miles on it.

My vehicle has 47K miles on it as the vehicle sat in the garage for 2 years ( 2019/2020) during COVID, it was never used. Recently as of Jan, Feb 2025, Slowly the car started to vibrate when starting the engine and the check engine came on. Every start in the morning or between trips, the engine would vibrate significantly , having the passengers inside (including kids) get worried about what is going on!. Also, an odd smell of burning in the exhaust , as though something other than fuel was being burnt. Took it to the dealership and they confirmed, an coolant intrusion. I checked online , to my surprise, I found everywhere that a lot of customers are having this coolant intrusion into the engine on the Ecoboost Engine and there has also been several class action lawsuit against this coolant intrusion into the engine. The Ford dealership mentioned , it would cost 10K to replace an engine and that is the only solution. With the powertrain warranty being within 60K miles, I am not qualified for the warranty as it is more than 5 years old as per Ford dealership. I am worried, that it could be very dangerous, as the engine could catch fire, if left untreated and I hope Ford acknowledge this known issue and not have their customers drive this faulty engine to end up into any disastrous issue with engine fires!!.
