2012 Ford F-250: sudden loss of power

Filed May 17, 2022 · Electrical, Fuel system · LA

Okk Main issue is what everyone calls the “Death Wobble”. It has done it countless of times since I’ve had the truck. Even after I bought a New Fox Single steering stabilizer. I have replaced quite a few things under the front end that I was told “Could” be why it kept doing it. The most recent I’ve bought for the front is brand new Fox Shocks just like the ones I have on the back and it still does it. I’ve had the front end aligned a couple times since I’ve had the truck and rotated my tires once too. And to this day it Still does that death wobble. It scares me every time too still. Im afraid ima end up in a wreck or cause a wreck bc of it. Another issue is I keep having this warning pop up saying “ Engine Temp too high reduced engine power “ bc it thinks the engine coolant is too low which it’s Not. And when I scan the code through the OBD port it just says “Engine oil temp sensor too low/too high”. I had the Ford dealership in my town put a new Oil Temp sensor in it but it still throws a code just about everyday I drive it. Another issue I had was the High Pressure fuel pump on the front of the motor go out Literally while I was sittn in my driveway at night after just driving it not even 3 miles down the road to the store to grab a few things. And it ran fine like normal but soon as pulled in the driveway an was rolling my windows up about to go in it just died on me an had to get it towed to the Ford dealership in my town. They looked at my fuel an said my fuel was fine with No contaminants in it. I was just Unlucky they said so that was basically 10k out my pocket to pay for a Whole New fuel system. The Death Wobble is my most concerning issue but other than that the truck has been awesome.

Tl* the contact owns a 2012 ford f-250. The contact stated that while driving at 50 MPH, the vehicle loss power steering assist without warning after driving over a pothole. The vehicle resumed normal drivability after a few seconds. The vehicle was taken to courtesy buick gmc abbeville (1201 u s 167, abbeville, la 70510) where it was diagnosed and determined that the steering column needed to be replaced. The vehicle was repaired however, the failure recurred. The manufacturer was not notified of the failure. The failure mileage was approximately 75,000.

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.

Egt sensor fault resulted in a "stop safely now" alert, shutdown of power while approaching the neches river bridge in beaumont, tx, a bridge on a 3-lane interstate (I-10). Engine subsequently shutdown while in heavy afternoon work traffic causing high potential for a major accident. Traffic behind and next to me swerved and braked on the 75 MPH interstate while the truck lost power as it just made the crest. Vehicle was towed. Egt was replaced. Bank 1, sensor 4. Second such failure. First was in august, 2015. Replaced with ac3z-5j213-b in aug, 2015 (the current failed egt). This time replace with ac3z-5j213-c, see photo for differences in sensor design. I have read rq 14-005, vehicle commanded engine shutdown, and cannot believe this topic was revisited with no action resulting to require the 15v‑175 remedy reprogramming for non-emergency vehicles. I ask the the federal safety agency revisit this topic to consider allowing owners to have the same PCM change to stop a single egt sensor fault to result in an immediate loss of vehicle power and causing high potential for injury to the public. As a mechanical engineer in the petrochemical industry, and having participated in many hazards analyses over 20 years, I struggle to see that the consequence of continued use with a bad sensor for a longer period, but at some reduced power, could ever be greater the chaos, confusion, and high injury potential from prompt removal of 70% vehicle power from the driver in 45 seconds. Towing a 5th wheel trailer and experiencing the "stop safely now" power cutout is a recipe for disaster. Thank you for your consideration, and I hope to hear of the reopening of investigation on this topic and allowance to reprogram the PCM.

I got on the highway and was doing a turnaround when I accelerated to enter the highway lanes a warning light that said reduced engine power appeared on my dash. Approximately 200' later my truck died on the highway. My high pressure fuel pump went out and apparently disintegrated sending aluminum shavings throughout my entire fuel system. The fix is to replace the entire fuel system at a cost of $11,200. The ford company is claiming the fuel was contaminated and caused the pump to rust and go out. I have never got a water in fuel warning light on my truck and have had all the required maintenance done on the truck. The insurance company had a lab do a sample of the fuel in my truck and the fuel met all the astm requirements.

Egt failure causes truck to lose power and shut down on side of road. This has happened on two different trucks of the same model & year.

On 28 september 2012 I purchased a new 2012 ford f250 diesel pickup from a ford dealer. On/about 1 november 2012 while accelerating (from approximately 10 miles per hour speed) into an interstate traffic lane this vehicle suddenly went into an engine near stall/loss of power condition which lasted approximately three to five seconds and then regained normal engine power. This was a very alarming condition as I was entering into high speed traffic and needed capable acceleration while entering into traffic. The truck had approximately 450 miles on it when this first occurred. I took this truck back to the dealer when the truck had 551 miles on it and they could not find anything wrong. While driving the truck on 27 november 2013, this same engine near-stall event occurred under a similar highway ingress condition when the truck had approximately 5,100 miles on it. I called the ford customer service hotline and was advised to take the truck to a ford dealer for a second checkup. I then took the truck to a different ford dealer on 6 january 2014 when the truck had 5,510 miles on it and they could not find the problem. Neither of the two ford dealers that I've taken the truck to for diagnosis will provide me with a further course of action to fix this recurring engine malfunction. I want this malfunction fixed or a new pickup to replace it, it creates a personal safety hazard for me and my family and the problem has been in the truck from when it was only a month old and had 450 miles on it.
