Engine Exhaust System problems of the 2012 Ford F-250

Driving truck it told me to pull over and shut engine off. I was stranded on the side of the road and it would not restart, had to get a tow home. I did some research and found this is exactly what my truck did as follows. When the egt sensor goes on the blink, the powertrain control module thinks there is an exhaust system overheating situation. The vehicle then goes into a �controlled power reduction mode� while five warning chimes are ringing away. This ends with the engine shutting down completely as soon as the truck slows to four mph, with no engine restart immediately available.

The contact owns a 2012 Ford F-250 sd. The contact stated that while driving at approximately 70 mph, the stop safely now warning light illuminated as the vehicle independently decelerated. The failure recurred and the vehicle stalled, and failed to restart. The vehicle was towed to a dealer for diagnosis and the mechanic stated that the exhaust sensor needed to be replaced. The vehicle was repaired. The manufacturer was noticed of the failure. The approximate failure mileage was 58,000.

The contact owns a 2012 Ford F-250. While driving approximately 5 mph, the vehicle stalled without warning. After several attempts, the vehicle failed to restart. The vehicle was towed to a dealer who stated that the exhaust sensor needed to be replaced. The vehicle was repaired. The manufacturer was notified of the failure. The approximate failure mileage was 30,000.

I was driving on I 26 and a warning came on saying to slow down and pull over safely. I dad no chance to do this as the computer put the vehicle in "limp mode". An 18 wheeler narrowly missed hitting my truck as we moved to the shoulder and the engine died. The truck would not start for about 45 minutes. We then drove to the dealer who said he could find nothing other than a warning to change the oil. In the past 2 weeks, the truck has shut down twice again. A tow truck had to be called both times. The first time I was on I 77 and the truck went into limp mode and the shut down as I pulled to the shoulder. The next time I was on us 521 going uphill with no shoulder. The truck again went into limp mode and then stopped on the highway. Cars and trucks were swerving to avoid us. My wife was crying because she was certain that an 18 wheeler would not be able to miss us. I called the sheriff and Ford and later had the truck towed. These two times, the cause was an exhaust gas temperature sensor failure. I believe #2 failed and then #3 (there are 4 of these sensors). Dependability is of course an issue here. But the real issue is safety. Ford has designed a computer system that stops the vehicle no matter where you are to save the engine and/or the emissions system. In doing so, the lives of the driver and passengers are put at risk and could be killed as a result.

While driving my truck on a busy side road, the message center flashed a warning, "stop safe soon". A audible chime was heard and the truck shut off. Complete lose of power brakes, power steering. I was not able to get the truck off the road completely since it happened so fast. Traffic was stopped in both directions while we did our best to push the 7,500 pound truck to the narrow shoulder. Since the shoulder would not fit the entire truck, it was basically half in the road. Traffic has backed up and we had to wait close to an hour for a tow truck. After speaking with the dealer, he told me the truck has a bulletin out about a faulty exhaust gas temperature sensor. This small sensor fault shuts the truck down and will not allow the engine to run.

The contact owns a 2012 Ford F-250 sd. The contact stated that while driving at an unknown speed, the "stop safely now" message illuminated and minutes later the engine would seize. The failure recurred numerous times. The vehicle was taken to the dealer, where it was diagnosed that the heat sensor on the exhaust needed to be replaced. The vehicle was repaired. The manufacturer was not made aware of the failure. The failure mileage was 38,000.

I have had to replace exhaust heat sensors 4 times in my 2012 F-250. The same sensor twice,first at 26k around June 2013 and and again at 46k, oct 2014. I've been stranded 3 times and had to be towed to a dealer. I occasionally pull a 42ft 5th wheel camper and am very worried it will happen while pulling it with no place to pull over. Ford needs to step up to the plate and get a fix for this problem.

The contact owns a 2012 Ford F-250 sd. The contact stated that while driving 70 mph, the vehicle stalled and an alert advising to stop the vehicle immediately illuminated on the instrument panel. The vehicle was towed to a dealer for diagnosis and the contact was informed that the egt sensor would need to be replaced. The vehicle was repaired. The failure recurred within 8,000 miles. The vehicle was towed and repaired a second time. The manufacturer was notified of the failure. The failure mileage was 48,000 and the current mileage was 56,600.
