The Ecoboost is always improving. From what I understand is they changed the CAM phasers.
Also where you live has a big impact on reliability. Salty roads and extreme cold take their toll on the vehicle.
When I lived in MD every car I owned had issues from seized brake calipers, to locks to engine issues from extreme cold starts, o-ring items like shocks from the cold, etc. Living in AZ for 25 years I have had practically no issues. Just pretty much wear items. Of course results will vary depending on who you talk to but this just my opinion.
