NHTSA Complaint #11609531 — 2016 FORD EDGE

I'm filing a complaint regarding my 2016 Ford Edge Titanium with the 2.0L EcoBoost engine, which required two engine replacements due to a defect causing coolant intrusion into the cylinders.The engine failed due to coolant leaking into the cylinders, a problem diagnosed and confirmed by Ford technicians. Both engines are no longer in the vehicle, but documentation is available upon request. My safety and the safety of others were put at significant risk on two separate occasions. The first engine failed at 67,000 miles, leading to the engine blowing while I was driving on the highway. This nearly caused an accident as the vehicle suddenly lost power. The second engine, which was a replacement from a 2018 Ford Edge with the same 2.0L EcoBoost engine, also failed in a similar manner at 87,000 miles, again while I was driving on the highway. On this occasion, I was left stranded on the side of the highway in the desert for 7 hours in over 100-degree weather, further endangering my safety. The problem was diagnosed and confirmed by a Ford dealership on both occasions. The first failure was diagnosed as coolant leaking into cylinder 3, causing the vehicle to misfire and eventually leading to the engine blowing. The second engine was inspected by a Ford repair technician during a recall service, where the same coolant leak issue was diagnosed. Less than two months after this diagnosis, the second engine also blew while I was driving. Ford service technicians inspected and confirmed the problem both times. Repair and diagnostic reports are available. The first indication of the problem with the original engine was a check engine light so I took the vehicle to Ford. The dealership diagnosed the issue as coolant leaking into cylinder 3, causing misfires. Despite this diagnosis, the engine failed before I could arrange for the recommended long block replacement. The second engine began exhibiting the same symptoms—misfiring and coolant loss—shortly before it also failed.
