Four problems related to diesel engine have been reported for the 2011 Ford F-250. The most recently reported issues are listed below.
7/7/17 - 2011 Ford f250, 6. 7l diesel engine, mileage 79530. (purchased December 2010). I was pulling a small trailer up an incline (8%) on I-64 in wv. On this portion of the interstate there was no emergency pull off shoulder. The truck operated normally for the first 3 miles ascending the hill. During the 4th mile, the truck began to gradually, but progressively lose power, going from 70 mph down to 0. At approximately 30 mph, the truck began to shutter slightly, and continued to do so until it stopped in the lane of traffic and stalled. There were no warning lamps or chimes that went off before the engine stalled. This vehicle is equipped with a �stop safely now� warning, along with many other warning indicators � but it didn't illuminate. The truck would not restart. I immediately call 911 to report that my vehicle was disabled in the roadway. After being stuck in the lane of traffic for about 10 minutes, I was able to drift the truck and the trailer backwards safely, off of the roadway, into the drainage ditch, after a break in traffic. Upon having it towed to a Ford dealership, I was informed that it was going to need a motor, and it sounded like it had spun the bearings on one of the engine rods. The engine would restart at the Ford dealership, but idled very rough. I confirmed that there were in fact metal shavings in the oil. The fuel was not checked for contamination. This vehicle has been maintained according to Ford's recommended service guidelines. Because of the cost to me to repair ($16,000 or more), I've elected not to continue with diagnosis (at $120 per hour) to determine reason for failure. Again, there was no warning systems active at the time the engine stalled. This was an original owner, personal vehicle, and only towed a trailer on occasion. I have video from dash cam w/audio of this event.
Catastrophic engine failure at 3 years old and 124,000 miles. This $60,000 2011 Ford F-250 super duty with 6. 7 diesel engine is totaled. Driving down the road at normal cruise the engine started making a terrible banging noise and shuddering so violently that I was forced to immediately leave the road. I stopped and turned the engine off. Got out and the ground was covered in oil. Stranded. . Dealership quoted me $24,233. 67 to replace the engine. Although this engine is falsely advertised to be rigidly tested for 250,000 miles, Ford has sent email stating that they will not stand behind the product. This truck is still financed and quite frankly I cannot afford and should not have to afford this repair. I have had exhaust issues with overheating and burning sensors which were replaced by warranty a couple times and out of pocket a couple times. I have read many reviews that the heat that is built up during a regen exhaust cleaning cycle damages the valves within the engine. I also read that Ford fixed this problem in 2012 but that leaves people like myself, who paid Ford $60,000+ stranded without a vehicle in just 3 short years. I have service the truck as required and have never abused it nor put it in mud, etc. Please look into this and see if there is anything I can do. It appears I may be without a vehicle and have to default on my lender with the cost of this.
The 6. 7 cid diesel engine driven vacuum pump suddenly begins leaking motor oil. Failure of this pump will affect 4 wheel drive systems including auto locking hubs and all interior climate controls. Loss of motor oil could cause engine failure. Failure of 4 wheel drive system during adverse weather could result in a vehicle crash or loss of control. Research indicates multiple failures of this part, indicating a systemic failure.
