NHTSA Complaint #11679971 — 2017 FORD EDGE

The first symptom on my 2017 2.0 L EcoBoost engine with 79,000 miles was a rough start and check engine indicator. The warning light cleared and engine ran better while at operating temp. The symptoms became worse over the next few weeks, when I noticed that there was no heat coming from the heater as the coolant was very low and the engine was overheating. I had difficulty removing the coolant reservoir cap as there was significant vacuum and no coolant showing. When I got the cap off, the coolant boiled up, leaving a small amount in the bottom. I added coolant to make it home and called the local Ford dealer who informed me that there is a service bulletin about coolant leaking into the cylinders and the repair might likely mean an engine replacement. The engine replacement would cost $12000 at the dealer so I brought the car to my mechanic who scoped the cylinders and found damage in the third cylinder. Since he had replaced nine of these engines for the same problem and knowing that the faulty engine design had been corrected in 2020, he recommended long block engine replacement, which has been completed. Had I not noticed the engine overheating, I could have been stranded or worse -- had an engine fire. My mechanic informed me he has now replaced ten 2016-2019 2.0 liter EcoBoost engines for the same issue.
