3 Engine And Engine Cooling problem

Failure Date: 04/04/2024

We have a 2012 Ford f30 diesel and we are having issues with one of the exhaust gas temperature sensors (bank 1 sensor 3) which would have been covered under Ford's recall campaign# 15m02. However, since our vehicle is 11 years and 9 mo old, they are declining coverage as the campaign is limited to 11 years.

4 Engine And Engine Cooling problem

Failure Date: 07/16/2023

Exhaust manifold stud broke causing leak in exhaust manifold. See NHTSA notice ssm 50330 for a full description of the problem. This notice covered all super duty pickups from the f250 through the f550 from 2011 through 2014. Ford also noted the problem in a customer satisfaction program letter, #17m05, dated 5 December 2017 but it was limited to the f450 and f550 models. My vehicle is an f350 . . . Nevertheless, these models all use the same 6. 7l diesel engine and would have the potential for the same issue. I have contacted Ford hq about this. Theystate I must go through NHTSA at this point. My Ford case file number is cas44584909. It may be just me, but I consider an exhaust leak under the hood to be a life-safety issue due to the potential for exhaust gases, especially CO, to leak into the cab of the vehicle. I didn't know what the issue was in July, but I had it inspected and repaired at my Ford dealer when I got home in August. That is when I discovered the extent of the situation. $40. 12 of the attached invoice is for routine maintenance . . . The balance is for the repairs necessary for the exhaust manifold leak. ($3,750. 53).

Failure Date: 02/21/2021

We have been maintaining our vehicle and had no warning lights at the time our truck died . At the time of the incident it had oil and water. We were driving on the florida turnpike at full speed when suddenly, the truck started shuddering, and then it completely lost power. A cloud of blue-white smoke came out of the back of our truck. We were lucky to be able to get off of the turnpike to a safe place. We could have been killed. The mechanic has determined that the engine is locked up and can't be fixed. Our truck only has 134,000 miles - it should not have blown up like this.

12 Engine And Engine Cooling problem

Failure Date: 07/08/2017

Summary: we purchased a brand new 60000 dollar truck in 2012 or 2013 and was assured by the dealer that it had a warranty to cover any issues until either 100,000 miles or 5-6 years, whichever came first. After 4 years of ownership and around 67,000 miles, the truck started experiencing problems with a high idle and then abruptly shutting off. When taken to the dealer, they couldn't replicate the issues during a brief evaluation. However, a week later, while on the way to the bank, to get cash out for are stay at the hospital to give birth to are 6th child the truck shut off and wouldn't start again. The dealer diagnosed the problem as a faulty high-pressure fuel pump due to water in the fuel and tried to charge the author $15,000 for repairs. The author questioned why the diesel fuel water separator and the second fuel filter system on the truck didn't catch the issue earlier and criticized the dealer for their negligence in ensuring safe and reliable transportation.

13 Engine And Engine Cooling problem

Failure Date: 06/23/2017

June 23 2017, I was traveling down the road when a message the read stop when safe popped onto the truck instrument display. I attempted to get to a safe area to pull the truck over but was unable due to a loss in momentum that I later found out was a manufacturer safety precaution due to a faulty egt sensor. I was now currently in the middle of the road and unable to restart the truck. After 20 minutes waving down vehicles so that a serious accident did not happen the truck restarted. I sent back down the road to attempt to get into a safer location instead of blocking 1 lane of the road. I was able to proceed . 9 miles before the truck shut off again on a blind hill. The tow truck was arrived and we were then able to remove it from the roadway. Ford has come out with a recall for there 6. 7l power stroke ambulances to not have this issue but as civilians we are stuck with a very dangerous and possibly life threatening shut down of the truck over a 57 dollar part. This is not a small instance on this happening just a quick online search will show countless others with the same problem. Fortunately no one was hurt because of the measures taken of the people or the road. This is not right and Ford needs to make a change. If you look into the background of this truck you will see this is not the first time of such things happening.

14 Engine And Engine Cooling problem

Failure Date: 02/24/2015

Driving along cold windy winter day, I got a message on the dash "stop safely now". Motor immediately went into limp mode, complete loss of engine power to the point where I had all I could do to get out of traffic. As soon as truck came to a slow creep, motor shut off. Truck had power however engine would not turn over, basically the truck left me stranded roadside. Called Ford roadside assistance, they said it would take up to an hour to get a tow (unacceptable). I was left inside the truck with no heat. Ended up calling a friend to tow me to a better location. This is a horrible design flaw shutting the motor down like that. Driver should be able to keep motor running to keep heater on. Driver should be able to proceed a few miles per hour to get out of a dangerous situation (stuck in an intersection, stuck on railroad crossing, stuck on bridge, etc). Many of these vehicles are designed and used to pull large trailers, RV trailers etc. I cannot imagine pulling a large trailer and having that situation occur while driving 65mph on a four lane highway. Very dangerous situation. My investigation is that Ford recalled all the f series that came equipped with the ambulance package however they decided not to recall all the other f series trucks that did not have the ambulance package. Evidently Ford believes that ambulance drivers and passengers are more important than all the other f series drivers with the same engine and components. Someone is going to get killed over this flaw and for what, a $ 60. 00 sensor?. These trucks are 50-60k new and to be left stranded over a simple low cost part is unacceptable and dangerous. Look at all the crashes that occurred with gm with the ignition situation. This situation is as dangerous by allowing the engine to completely shutdown. Owner is left helpless and more than likely in a dangerous situation.

15 Engine And Engine Cooling problem

Failure Date: 12/11/2014

Turbo charger tube failed at the plastic connection joint on the turbo. Plastic connection broke causing a sudden loss of power at highway speed. 4-failures in fleet trucks with the same issue. One turbo hose had a crimp band joint failure. This could result in a rear end crash on a truck pulling a trailer. Ford said its not a problem. 6. 7 engine equipped.

16 Engine And Engine Cooling problem

Failure Date: 08/26/2014

I was driving down the road at 45 mph in 5 o'clock traffic and a stop safely now message came on my message board and immediately shut my truck down on the road blocking traffic and I was pulling a dump trailer. There was no way to push it out of the road and no where to push it to if I was able . Waited on a tow truck for to hours while all the passing motorists got angry and made that section of the road very dangerous!.

17 Engine And Engine Cooling problem

Failure Date: 08/12/2014

Was going into an intersection and my F-350 died and displays a stop safely now message, which caused me to die right before I went through the intersection. Ended up being an egt sensor. Their are 4 on this truck and now another one has gone out leaving me stranded again. This ha sbecome such an issue that Ford has a national backorder on these sensors, and they wont warranty the part, and the extended warranty will only cover them as they go out. This truck only has 60,800 miles on it. This is unacceptable.

18 Engine And Engine Cooling problem

Failure Date: 06/19/2014

I was traveling with my three young children to a town approximately 40 miles from our home. I was going about 70 mph on the freeway, and just as I started to exit at an off ramp a warning tone sounded and my dash flashed "stop safely now". I was exiting anyway and there was no where to pull over, so I continued up the ramp. I quickly turned into the nearby parking lot, and just as I quickly pulled into a parking spot the pickup completely died. It was only about 30 seconds from when I was first alerted to a problem to the vehicle completely shutting off. It was pure luck that I was able to find a safe place to pull over that quickly. I just kept thinking about how dangerous that could have been had I not been able to immediately get off the freeway. If I had lost power on the freeway there could have been a terrible accident. We were then completely stranded and had to wait for a tow. Luckily the weather was fair as we would have been unable to use any heat or air conditioning while we waited for what could have been hours for a tow. Not to mention that we live in a very rural area and often times do not have cell service. Also, we frequently are towing our stock trailer loaded with horses or cattle going up and down steep grades. I can only imagine what would happen if the pickup decided to shut off at those times. I was truly shaken up by this incident and the thought of what could have happened if the circumstances had been different. I am pleading with you to prevent certain future tragedy by forcing Ford to fix this problem. It's a simple fix (in my case it took the dealer less than an hour) and there is no excuse.

19 Engine And Engine Cooling problem

Failure Date: 04/05/2014

On two different occasions now, my 2012 f350 6. 7 powerstroke engine is shutdown due to a egt sensor failure. When this happens, you loose power within seconds. If you are not in a position to pull over at once, you are stranded in the road or highway. This is a fatality waiting to happen, if it has not already. Ford with replace the sensor free if under 36,000 miles but they have no long term corrective action to resolve this. They just keep on replacing them again and again. This is a major issue with thousands of owners at risk everyday. Just read the reviews under "Ford 6. 7 egt sensor problems" from what I am told by many folks, Ford has not intention of resolving this long term. I have a $65k truck that I can not depend on and even worse could get my family injured or killed. Please help!.
