Been hanging around the forums since 2013. And turbo and engine failures are not unheard of, but they are uncommon. The 3.5l eco is a solid engine, more so than the 5.0l imo.

Here’s a poll that was done at a Ford dealer with their garage staff of which engine they would buy……..


It's interesting....the younger techs prefer the EB, the older, more experienced take my opinion

Two picked it for the towing ability...while the 3.5l has more torque and is rated to tow more but they are completely unaware. And loved the one about the ECHO??? - echoboost??? He doesn't even know what it's called. "You got to be on the power, all the time just to keep the power, in the throttle to get the power but you just get to speed and cruise with the 5.0." Yeah.....that's not really how a turbo works.

Truth is, a lot of people are just plain stuck on 8 cylinders.

I put no stock in that video at all. Even my service writer thinks the 5.0L is the better choice but he can't tell anyone why except t hat it's his opinion. And he drives a 2012 Focus and claims that it has no transmission issues whatsoever. SMDH.

Threads like this prove most come to boards to cry about their failures, not praise their success. I get sick of those who have a problem and ride that one horse to their grave. Then the others who know nothing about what they drive, but are experts when there is a problem.
I remember when the 3.5L came out and the newness had people griping the engine was junk. It'd never last. The fuel economy sucked. It wasn't the replacement for displacement. Blah, blah, blah. Years later, after working out the minor bugs, like ALL new platforms do, it's the main engine type across Fords line, for good reason.
Im in the same boat as the OP, looking for a used truck for my son. I know the 2011 EcoBoost had issues, but it's the exception. Yes, the early 5.4L engines blew plugs, but it wasn't the rule.
Ive logged more miles in Powerstrokes than most, and at close to 3 million miles, I NEVER had issues with the dreaded 6.0L's I owned (5) or the 6.4L's (2), but both motors were supposedly junk. Again, exceptions, not rules.
Ive only owned one EcoBoost, snd it was a 2016 that amazed me. No, it's not like my 6.7L, but it was a miracle. From what I hear, there are timing belt/chain issues that can arise, and it is suggested to do some preventive maintenance there after 100k, but despite the early reads of impending 2011 EcoBoost doom, I'm finding more and more satisfied drivers well over 100k on their pregnant sewing machines, and happy without real issues.

My buddy had a '11 with the eco boost and had no issues with it, although it only had 30k on it when he traded for a new one9he gets a new truck every three years). My wife's '12 has just under 80k and it has been 100% reliable, we are probably going to trade it off this spring and will more than likely get another one with the 3.5eb. My buddy went from two EBs to a 5.0 in his '17 and he regrets not sticking with the EB.

I would not be afraid to buy a used EB engine, just make sure to change the plugs if you can't verify when/if they have been changed. On the 3.5 it's a pretty easy job to tackle for people with even little mechanical ability. On the test drive just make sure to listen on the cold start for the rattle they can get and if it has it walk away.

these internet forums are a great source for information but they can make less common problems seem bigger than they are. When I bought my '01 I was sure the 5.4 was going to start spitting plugs out from what I read on here but that ended up being a very reliable engine. I'd be more hesitant to buy an older 5.0 than the 3.5.

Technology has come long ways, i remember also those people saying it was junk and that the turbo's were a 100k maintance item lol..... When my 87 nissan 300zx was stock i raised my boost level to 16 PSI (stock was 7lbs) i beat the poor **** out of that turbo and took the beating for 2 years and that was with a stock 150k turbo. The Ecoboost proved itself and would be a good contender if they ever decide to even put it on a Super Duty.
