Their is a recall notice going out for 2011-2014 F250-F550 6.7's. You can look up your vin on the Ford site now and see it. Recall #14E03. I think it has to do with emission's.
I received an urgent/recall notice today, and my truck is a gas 6.2 model. The notice came from my dealer, not Ford. Recall is is "13 B 16". When I looked it up inputting my VIN, it says "REPROGRAM PCM TO CORRECT ABS/OBS FAULTS THAT DISABLE OBD MONITORS WITHOUT ILLUMINATING THE MIL"
It goes on to explain that is is an emissions related concern. Sounds like the same thing?
