Engine Shut Off Without Warning problems of the 2012 Ford F-350

I was 300 miles from home for work for a week. On day 1, while driving on a residential street, I suddenly got a message on the dash that stated "stop safely now". Seconds later, as I was pulling over by the curb, the truck shut itself down and would not start back up. I had to rent a vehicle (being away from home). On day 3, I tried again and it started. I drove it a block away to the place I was staying. Entering the parking lot, I got the message and it shut down again just as fast. At this point I had to arrange transport of my truck back home. $650 and 3 days later, I finally got it home. Started it, ran for a few minutes parked so tried to drive it. Made it about 1000 feet when it shut down again and left me stranded on the highway. Each time it shut itself down, I had to wait a minimum of 1 hour before it would restart. After researching, it seems that my egt13 sensor has gone bad and has to be replaced. Had it shut down while I was on the interstate, the results of this could have been a whole lot worse than the expense of a rental and transport. My research brought to light that this seems to be an ongoing problem with Fords that needs to be addressed and.

Exhaust gas temperature sensors fail repeatedly. They have been replaced multiple times. Reductant heater a control performance has now failed as well (all part of the diesel emissions disaster). Aside from constant breakdowns due to emission related items the truck has shutoff abruptly when it encounters any of these problems while driving. Vehicle has shut itself down at highway speeds due to these issues. Vehicle said pull over and within 10 seconds it shut down on the freeway endangering the lives of my family and others on the road. As far as when this has happened it has been multiple times. It has been in the shop on 3 different occasions to replace the same sensors and now other components of the diesel emissions package are failing as well.

Due to egt sensor reading high eg temps truck shut off with no warning. Left me stranded in the middle of a busy street until a good samaritan pulled me to the curb. Truck was fully loaded, but not over loaded.

While driving an alarm sounded and the driver display stated " stop safely now" and lost all throttle response. When the vehicle stopped, the engine shut off and it would not crank or restart. It had to be towed from a busy intersection. The fault turned out to be a failed exhaust temperature sensor. It was not even a engine component. It is programming alone that prevented moving the truck to a safe location. What if this was a railroad grade crossing? or had kids in the truck? I can't let my wife drive it now it has 4 of these sensors and only the 1 failed one was changed. Ford has a TSB 13-13-3 on this. It is in its 3rd revision. They know of the problem.

The truck dash display read stop vehicle safely. I immediately looked for a driveway and found on about 50' on the left. I barely made it into the parking lot I had chosen when the engine shut down. I did not make it to a parking spot, but I was off the road. Vehicle was towed to dealer and problem was found with the exhaust temp sensor. It was replaced. I was billed $86. 20 for the work. Aaa paid the tow, but if I hadn't had that, I'd be out that as well.

While towing loaded trailer on 2 lane highway, truck computer flashed message to "stop safely now". Engine shut down and would not restart. Dealer inspection found a faulty exhaust sensor. No other issues with cooling, oil or engine occured. The safety issue is that the new control system software is designed to shut down engine in the event of a faultly sensor in order to protect the vehicle. The system should alert to the issue and allow the human to determine if it is safer to continue driving and risk damage to the vehicle. A control system that is not aware of the road, traffic or environmental conditions should never be allowed to override human requirement to continue driving out of harms way.
