NHTSA Complaint #11417691 — 2017 FORD EDGE

2017 Ford Edge w/2.0 EcoBoost engine. Vehicle had about 64000 miles, started vehicle in morning and it idled rough. Check engine light came on. I used a code reader and it showed "random misfire, cylinder 4" P0304. Reset the check engine light and drove for about 10 more days. Started again in the morning and it idled rough causing the check engine light to come on again. I took vehicle to Ford and they diagnosed "fluid intrusion into cylinder walls". Service adviser knew exactly what it was when I described problem, saying "this is a common occurrence". Replaced engine at a cost of $5302 since it was approx. 6ooo miles out of warranty. Found numerous online complaints about this same engine and same problem. Ford seems to know about it because in Dec. 2019 they issued TSB #19-2346 describing the problem and the steps to fix it (new engine and the required parts to order). many online complaints describe low coolant and overheating. My engine would of gotten there if I hadn't taken it in to the dealer.
