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.
Must be not all 2014 6.7's are being recalled just yet. I checked on my 2014 F350 (Ford recall site ) bought in April of 14 and it states ...No Recall or Service alert. 15,000 miles and no problems to date. Think I will call them.
