2012 EcoBoost - Long term update
In June of 2012 I ordered my truck outfitted the way I wanted and took delivery in August. Per signature it is a 2012 F150 Max Payload. Have really enjoyed the truck. Pros: Electronic steer...

Have had dealer replace (under warranty) front hub 4x4 mechanism twice. Apparently 2011-2014 rely on vacuum to stay disengaged and have had issues with insufficient vacuum
Didn't end with 2014. My 2017 had that problem, and the F-150 forum has people with 2018 trucks still reporting it. The back check valve in the vacuum line between the vacuum pump and the IWE assemblies fails, intermittently, quite often. Ford has, finally, redesigned that check valve. They did that just this year. The solution, prior to Ford's re-design, was to go to the big box auto parts store and buy a YG360 check valve to replace the one that is stock on Fords. The YG360 is still cheaper than the Ford re-design. I bought two of the YG360 backcheck valves a year ago. I installed one in place of the defective part, and put the other in the glove box under the theory that if you are prepared to fix a problem, the problem will not occur. *G* They cost less than $10 each when I bought them. The problem has not recurred since I replaced the backcheck valve.
