Seems to be anything built in the last 15-20 years is pretty reliable.
Not in the 1st 5-10 years, no...they don't care after that...its more like they can't build 'em too well, won't sell enough replacements in the future...there's no way they couldn't "tighten up" a few weak points and make things last easily twice as long as they do now...without spending much money to do it...just a few design tweaks.
I agree with checking with real live "boots on the ground" mechanics though...as I said earlier, when I did that regarding buying a used Edge, the feedback was a lot different than my online research...but you can't just rely on the opinion of one guy, because sometimes a certain shop will see some anomalies, or have built in bias...like the guy that our family uses...he doesn't like Honda transmissions, and therefore the brand...he was very critical when he found out I bought a Honda product instead of the Edge I was considering. Truth is that Honda does have some weak points with some of their trans, but I knew that, and had done the model/year research already, as far as which ones were more desirable than others, and also, how to limit recognize and limit the risk of failure.
Just as in this case, taking the opinion of one person can lead you astray, when I talked with another Ford mechanic, he had seen plenty of the Edge failures that I had read about online.
Just like when I was still bending wrench's at a dealership, we had a certain model that had proven extremely reliable as far as engine/trans failure, for many years...and didn't hear of anything otherwise from anyone else either. But then we had 3 come in one summer, all the exact same failure, to the point of being able to order the parts ahead of time before even taking the last one apart. Now, apparently they actually had issues with this particular problem, as the OEM had updated parts for this repair.
Even talking to different techs in the area (for the same brand) may result in skewed results as often times dealerships in the same area all attend the same schools and/or update classes put on by the same area service rep...so they might get some of the same info as far as what's been going on in other shops/industry wide.
