Two problems related to other fuel system tank assembly have been reported for the 2015 Ford F-350. The most recently reported issues are listed below.
Def tank filled at 7300 miles. At 9600 miles a "exhaust fluid low" 50 miles til engine idle. Picked up exhaust fluid and refilled-only 2 gals added to overflowing. Did not reset, went to stanley Ford kenai, ak. Countdown went on, then"engine idle at next restart" dealer says to bad nox sensors, replaced and codes cleared. 15 miles later, exhaust system failure" engine will idle soon" fortunately I made it home in the dark and 40 miles in the rain. Now it has gone into the "engine idle" mode and "check your manual" dealer called, tow truck called, soon to be going back to dealer.
Exhaust fluid message on dash that speed will be limited to in 50 miles. Went and bought a new jug of blue def. It took 2 gallons to fill to running over. Then before I got to the kenai, ak dealer, it says engine will idle upon restart. The kenai, ak dealer said up and down stream nox sensors had failed and reset the codes. 15 miles later, I get and "exhaust system failure" engine will idle soon. Made it home(40 miles at 10pm and raining) then it says engine idled, check operator manual. Basically it thinks my def tank is empty, but it has only 75 miles on a completely full tank.
