Find a later build date like 2013ish and newer. The 2011's gave ford a very bad name with the failure rates:
poor material used in bearings for turbo, glow plugs braking and eating a cylinder, sensors and dpf/eef system failures, lifter/valve mechanical failures eating the engine, coolant system leaks esp with radiators, The newer series of 6.7L are making big waves in reliability. but, the 2011's were not a good year plain and simple. Late 2012's and up had some changes and it seemed by 2013/2014 they had it all figured out.
Let me help with the details-
-turbo bearing failures largely attributed to early tuning, and being horrifically overspend. Yes, they fail in stock form but seldom.
-glow plugs never were an issue. The problem was a limited number of trucks in a specific vin range that had subpar heat treating on the valves which led to them cracking and destroying the motor. First step of troubleshooting was to pull the glow if and see if the tip was gone "ding ding" guess what, the bits of valve took the tip off.
-emission related sensors causing the truck to shut down was corrected by an updated flash that simply put the truck in limp mode instead of disabling the engine.
-the lifters are the same now as they were then. Higher miles and engine hours show the failures first, hence why the oldest trucks may start having problems.
-same story with the rads, higher miles equals more failures. 11-16 rads are a the same. Check body mounts for excessive movement before replacing the rad.
Don't broad brush 2011 as a bad year. Not the case at all.
Sorry but that’s not true at all. The early 2011 had ceramic material for the turbo bearings and failed stock or tuned. Then they went with steel bearings and the issue was basically gone...
The glow plugs were an issue plain and simple. They were melting the tips off and flat out breaking. All though it wasn’t widespread as my initial post failed to mention so my bad. It was enough of an issue to warrant being aware of. Because, we’ll, you know it’s so easy to just pull a glow plug when a buyer is looking at a used truck...
The DEF/NOX/DPF sensor issues were not just a programming error. They were simply failing even after multiple replacements hence why so many wanted to delete regardless of any warranty.
Well I don't like the sound of that, seeing as I how I bought a 2011 with 165k on it! LOL
Honestly, I had the same worries as you. If you can get it well below Blue Book, buy GAP insurance, and everything feels tight, then go for it. That being said, these trucks are nice but not really "rare" so there is no harm in just being patient and waiting for a low mile 2012-14 to come up.
It really just depends on your budget. But I agree, if it looks to have been modded and then put back to "stock" to sell, I would run in the other direction screaming.....
Don't mind him, he's just super negative towards the '11s. Any truck can have a failure regardless of the year.
Don’t mind Jman either. He can’t stand the fact that anyone would ever mention any shortcomings of a 2011 powerstroke. I openly bash ANY truck from ANY brand. I’ve owned Cummins and powerstroke (never owned a Duramax soon clue) and both are great platforms and each generation had their qwerks that are good to be knowledgeable about. My current 7.3L has plenty of items that needed attention when I bought it. The fleet of 2014 Cummins and Powerstrokes have been basically flawless besides normal maintenance and one small coolant hose on a powerstroke. I simply informed the thread starter of issues (hoping they would research more themselves). The 6.7L is a great engine.
So to the original thread starter I simply told you about the bad things that came up in the 2011s and from researching and personal experience with a fleet of Cummins and powerstrokes feel the 2014 and newer were just a must less risky build. There weren’t a whole lot of changes but enough to see a drastic reduction in shop time with 2014 and newer.
