  • 9,675 miles


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.

2015 F350 6.7 diesel with 46,000 miles that is down because hpop is defective and spreading medal through system. Ford has inspected and said it is because of water in fuel, even though no warning lights or codes are available. Ford pulled sensors out of engine and rejected repair because of tarnish on sensors. The only codes were for (low fuel pressure & reduced power). No other codes. Initial inspection revealed about 3/4 inch of water in water separator but no light or code. The warnings occurred when truck was started and it ran about 100 ft before being shutdown and towed to dealership. This appears to be a common problem since Ford offers a repair kit for this issue. Total cost of repair is between $9500,00 & $12,500 dollars and this on a truck which is still under warranty that Ford will not honor. The truck wasn't a year old until May 2016 and has been down for over four months because Ford will not repair. This is the Bosch C4 series pump.

During regeneration of the diesel particulate filter the truck loses power and operates roughly. This last occurred as I was merging into traffic on the highway during slick road conditions. This could have very easily resulted in loss of traction and/or collision as I was unable to accelerate to speed.
