The contact owns a 2012 Ford F-250. The contact stated that while driving at various speeds over 50 MPH, the vehicle shifted into LIMP Mode. No warning lights were illuminated. The vehicle was taken to a local dealer, where the failures could not be duplicated. The vehicle was not repaired. The contact stated that the failure persisted and that the transmission was slipping while shifting. The contact also stated that prior to entering the vehicle, he noticed a fluid leak underneath. The vehicle was taken back to the dealer, where unknown transmission repairs were completed; however, the failure recurred. The vehicle was then taken to an independent mechanic, where the fuel pressure regulator and heater malfunction failure codes were retrieved, and it was diagnosed that the Diesel Exhaust Fluid (DEF) tank needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure. The approximate failure mileage was 160,100.

Many early model vehicles with the 6.7 Powerstroke experience broken exhaust manifold bolts. Ford corrected this problem after the first few years of known defects but never issued a recall for the faulty design on 2011-2012 models. The exhaust leak can lead to a lack of power, “limp mode”, and/or a fire as the exhaust is located on top of the engine (not a common design). While Ford is aware of the problem, they’ve done nothing to rectify the situation.

When attempting to accelerate for passing slower traffic, vehicle lost power and went into the limp mode. Problem seems most present at around 2000 RPM while attempting to increase speed. It appears that this problem is occurring when the turbo boost is increased. Research of this problem has shown that many owners are experiencing this same problem with the eco boost engine in this and other year models. The federal safety agency began an investigation in 2012 but dropped the probe when ford said they had resolved this issue. No recall has been issued for this problem but it is definitely a "safety issue" for drivers of this equipment. Headed for the ford dealership tomorrow to see how this can be resolved.

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 egt 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.

I started the truck one morning to head to church put the truck in (d) drive headed out down the hwy pulled up to a stop sign on the way when traffic cleared I pressed the accelerator and the engine revived up real high but the truck didn't move and about the time I started to let off, the transmission clunked and took off and shifted weird between 1st and 2nd. The truck has responded two other times in the very same way once going about 40mph it reacted like the truck shifted in neutral. Ford dealer replaced the front pump in transmission, it still shifts weird and makes a terrible whining noise. Two or three times under acceleration to pass another vehicle the trans down shifted from 6th gear to 4th and would not shift back up, and then the opposite occurred pressed accelerator to floor running about 45mph to pass another vehicle and the trans never down shifted and I had to brake and fall back in behind that car before a head on occurred. There is definitely a safety issue with this truck, I have filed lemon law action and ford engineer came and drove the truck and he said there was no unusual concerns with the truck. Someone please investigate this before someone dies.
