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.
BB_TX - Do you know if the recall will allow more time for you to get to a safe place before engine shut down? I'd hate to be pulling my FW and all of a sudden the thing shuts down.
