It sucks that the 2.7 blew up, but if I built 1,000,000 engines in one year, a couple of them are bound to let go. It's the first 2.7 I've heard of that came apart, so they can't be a bad design. Someone had commented about techs not being able to troubleshoot. Vehicles today are way more complex than they were even just 10 years ago. So many things are monitored for emissions reasons, that a check engine light can be a real pain to figure out. Especially on a new model, nobody knows what the common problems are yet. Most techs are flat rate, and don't get paid to fiddle with something all day, they order the most obvious part and send it out the door. A lot of the time, there is nothing the tech can do until the manufacture figures out the problem,and can come up with a fix. That's where TSBs come from.
Have looked into battery cut off switches. We have them on all our vehicles. It's just an added protection if the vehicle doesn't get used for a couple days or a week. There mounted inside the cab for easy access. If Ford can't figure it out, this is your next best thing.
Yeah that sucks that you have had such bad problems with your truck. I would definitely not say that the 2.7l is a ****ty motor though. First years on new trucks with new motors are almost always pretty rough. My fathers old 09 Ram 1500 has a ton of problems with the hemi but his 14 Ram with the same motor is running like a champ. Though it is too soon to really say, the few guys I have heard of with the 2.7 with over 100,000+ miles on them have had no issues. One guy worked at shipping business where they drove hundreds of miles on the trucks damn near every day.
I had a 2013 F-150 for over 2 years never had any dead battery issues.
My 2014 had a dead battery at around 11,000 miles. It was an all stock truck too. The only reason I found out the battery was bad, I lost steering two times while turning corners. I took it to Ford , they said could find nothing wrong.
When they were pulling it into the garage , the courtesy guy lost steering. They took it back and looked again , magically it was a bad battery that caused lost power steering. The battery only had 274 CCA out of 750 CCA.
Good luck OP, hope it all works out.

Super Knock,
An unfortunate characteristic of modern boosted gasoline engines. It is an extreme pre-ignition event that can destroy any boosted gasoline engine, it usually happens at lower engine speeds and higher loads. Many thoughts are out there for the exact reason for this.
I'm sure the 5.0 and 3.5 have had some issues but look at how many Ecoboosts under similar conditions have had catastrophic failures. Kicking out a rod through the side of the block is a pretty serious failure and these engines have pretty stout connecting rods and bottom ends.
i think his engine blew up...
at least it's not a "will a CAI void my warranty?" or "what tires can I fit" or "what tuner is best" or "show me your wheels, go!" f**in stupid thread like has been popping up every day lately.

I thought at first this could have been a LSPI event also, but the OP stated he was doing 60mph when the engine let go. Usually also LSPI events happen in the smaller 4 cylinder boosted engines vs their V6 or V8 big brothers. It's mind boggling to think what could have happened since at those speeds the engine is virtually at no load (I think it takes something like 35-40hp once a vehicle is up & moving to maintain that speed). But I've always said it, anything built by man is subject to fail at anytime.
What else could it be but LSPI/Super Knock (rods through the block)? I fully agree that the power level seems too low but the RPM is in the right spot for it to occur. There are more than a few posts very similar to this. Some of the first LSPI testing was done on the 3.5EB, LSPI/Super Knock doesn't seem to care about the number of cylinders although I feel the smaller (GDI Boosted) displacement engines may be more prone to it.

It is pretty strange ... Usually you would have to be into the boost pretty hard to experience a LSPI/Super Knock situation and in most cases when cruising @ 60mph on the highway you wouldn't be into the boost at all.
I typically assume best intentions but for some reason the information in this thread didn't feel right the first time I read it after it was first posted and still doesn't after I just went through and reread it again.
It looks like the OP posted a question in the general f150 forum 2 weeks prior asking if there were any major issues with the 2.7 and then a few weeks later created this post. Doesn't look like he's been online since either.
The last thing I want to do is attack the integrity of any post but this one makes me suspicious.
OP if you're following this thread, could you provide us an update on the outcome of the repair on the 2.7? If possible, could you share the warranty paper work? Thanks.
