[QUOTE=blownup5.0;7130939]dsHappens to every brand though. No worries. Ive saw it from them all. Gm actually gave us a truck because ours was so bad once. Absolute trash. Trans. Motor. Everything. We had paid cash for it. They gave us an identical truck one year newer. With the same engine and trans. Ran perfect for nearly 300k until rust took it. They also had to replace a duramax last year for us because of their burning to the ground problem. Our other duramax has been back to GM many times going into limp mode. Several thousand in repairs on it. Most under warranty. Amazing how the good one of the three burned to the ground while that one won't. Lol. I also know of two cars that blew up the day they were bought. A wrx sti and a crown vic. Lol. Saw a Toyota lock up once going down the road in the first few days. No gear oil in the rear end from the factory. Toyota said two people would lose their jobs over that one. One near the Port and one at the regional place had signed off on it. I also personally had a dodge rt blow up petty new. Went to pass a car, floored it and was set back in my seat for 2 seconds then she blew. Lol. Dodge put another in it but it was hit by dummy and totaled so I don't know if it would have lasted.

I own a shop. I'm more surprised when my newer vehicles perform than I am when they break. When you see it every day you just come to expect it. And they break in such comical ways that didn't happen in the past. Ive seen a ton of motors blown. Never seen one look like it got put in a blender though. Direct injection and cylinder deactivation does give a blown motor more potential to break more stuff though.

Im not on any GM or Mopar forums but I do a lot of work on them all. I just finished putting a vortec 454 in an 85 c10

I predict this failure is going to be an engine defect. 2700 miles isn't enough to start seeing significant carbon buildup in deactivated cylinders, and from what I've read, appears you have to really be working hard for economy to get it to kick in.

Also read that Ford took a note from the other brand's failures and strengthened the rings and landings.

Every failure I've personally seen in cylinder deactivating engines in my shop have been lifter/ adjuster failures. Either wiping the cam or dropping a valve. But I agree that surely to God Ford learned something from the 15 years of failure in the gm and dodge engines.

And I also agree that an engine that fails at such low mileage had a defect to start with. A Crack in something. A poorly cast part. Machining defect or something. Loose

As far as getting it to kick in, I can make mine kick in any time I want on anything flat or down hill. It's actually easier to get to kick in than the stupid start stop. I spent an entire two week vacation trying to get it to die at a stop sign or light or even in the parking decks with my brother in law in it. Never did either. With my exhaust my 10 and 12 year old girls can tell you when it's in 4 cylinder mode from the back seat.

Just got another call from the dealer this afternoon, they stated that they think my engine dropped a rod. Really don’t know how a brand new 2700 mile engine at idle can do that other than faulty parts from the factory but the dealer states they are investigating my engine and will keep me updated.

The engine "blew up" and it "dropped a rod" are not terms a competent mechanic working on a modern engine should be using.

Caveman Charlie

True,, but most mechanics are used to dealing with people that have no idea of how anything works. Using easy terms that they may have heard around before is the easiest way to explain things.

It would be great to know what exactly happened though.

I would love to know more specifics about what "dropped a rod" means. There aren't any small or weak part failures which can cause that event.

Do you lug the motor a lot? Trying to save gas?

I don't now how truthful it was back in the day but it used to be rumored that lugging the motor is bad for the bottom end. I know we typically see lower RPM based on shift strategy, however I bet a person can feather the throttle enough to prevent a shift and give it just enough gas to keep on trucking down that super flat highway.

Still at such low mileage, how could a person hurt the bottom end even by today's standard.

So I live in rural Illinois and 99.99% of my driving is on 2 lane county roads that are 55 MPH and interstates that are 70 MPH. My truck is usually
in 10th gear at 65-80 MPH I have never taken it out of normal mode except for last Sunday morning when I tried eco mode at 75 MPH. Nothing I’ve done with this truck has been extreme. I am hoping the dealer gives me a more detailed explanation in the near future of the engine failure.

Sorry it happened you guy. Good thing is it’s new and the warranty will fix it.. I would lobby for an extended warranty from Ford for free after the repair is done. Hopefully after it’s fix you can change your user name. I know it must feel awful. Are they treating you right? Rental or loaner?

Keep us posted until you get it back.
