I just had an '07 GM 5.3L blow a rear main seal at 70,000 miles. Would have been almost $3,000 to fix from the dealership, but thankfully it was covered under warranty. GM's 5.3L has been around since what...1999? GM small block's in general have been around since 1955. Most would consider it to be a well proven engine.

Still, just because an engine is proven or isn't proven doesn't mean anything. Stuff just happens sometimes, and with modern vehicles.....when it does happen, it's usually expensive. It's just the nature of the beast.

If I was truly worried about it, I would look into an extended warranty plan. Otherwise, I buy what I like and drive it until I don't like it anymore.Que Sera Sera.

At what point is an engine proven? Is a manufacturer supposed to not come out with new engines?? Are they supposed to keep them the same for decades, to satisfy some peoples definition of "proven?"

With EPA requirements advancing to rapidly, engine technology will change and upgrade rapidly. At some point, you have to buy something based on faith.

Or, do you "assume" that because 2009 EB's are going great at 3-5 years (they are 1.0's), that they will all be reliable. After all, they will all be twin turbo V6's??

I'm sorry, I just don't get this type of statement. EB V6's have been out since the 2009MY. We are now coming up on the 2013MY. 4 years is not enough?? What is??
great post 08SDGal, i think you have it mostly right, Ford has a lot riding on these engines! Ford has a lot of experiance with turbos and the electronics that make these engines run as well as they do. I wonder how long ford tested the ecoboost before it went into production, I have to guess it was years!

The first ones came out in 2008 in Lincolns only. Then they expanded from there.
