NHTSA Complaint #11676759 — 2017 FORD ESCAPE

I own a 2017 Ford Escape with approximately 102,000 miles. I am the original and only owner and have had regular maintenance done on my vehicle the entire time I've owned it. After a recent 9-hour road trip, I experienced sudden engine failure with no prior warning signs. My local dealership has diagnosed the issue as coolant intrusion into the engine, which caused catastrophic engine damage and now requires a full engine replacement at a cost of $8,800. After researching the issue, I discovered this is a known and widespread problem with EcoBoost engines in 2013-2019 Ford Escapes and other Ford vehicles. Ford has issued Technical Service Bulletins regarding this, and there is at least one ongoing class action lawsuit related to engine failure caused by coolant intrusion. This problem poses serious safety concerns, especially when it causes vehicles to fail unexpectedly at highway speeds or in unsafe conditions. I am filing this report to document the issue and urge NHTSA to investigate this known defect.
