I own a 2015 ford f-350sd with approximately 42,000 miles that I bought from the ford dealer in september of 2018. So, I haven't even owned the truck a year yet. On july 12, 2019 I was driving down i15 headed to a camping trip. All of a sudden, my check engine light came on and then a message saying reduced engine power and my truck went from 70mph to 5mph and just barely got me off the interstate. I had the truck towed to the ford dealer where I purchased it. They diagnosed it and said there's metal throughout the fuel system, the hpfp is going bad and wearing out, there is also rust and water in the fuel rail. In order to fix the problem, the bill will be a little over $11,000. In december right after I bought the truck, I took it into the ford dealer and had them fully service the truck, check the oil, change both fuel filters, etc. I have all receipts to show ford that I have maintained the truck. I have fully maintained the truck and have drained the water separator monthly since I purchased the truck. I have done everything on my part to make sure the truck is well cared for and maintained. I have now been fighting with ford corporate for 5 weeks now and they are saying this issue isn't covered by warranty. It's a shame that you buy a truck from the ford dealer with a 100,000 mile warranty and now ford is claiming that this issue isn't covered by warranty. This is a known faulty fuel pump that wears out prematurely and is costing consumers tens of thousands of dollars to repair and ford will not stand behind their warranty! This is a shame and ridiculous on fords end!

At times and very frequently truck is losing power to accelerate, very slow to accelerate, will not go over 50mph. This happens everywhere doesn't matter the speed or location. When this happens the turbo psi reads 0, and you can't hear the turbo. A warning will come up that says the exhaust needs to self clean and drive to clean. Sometimes it will have thick smoke come out the exhaust that stinks. Sometimes the truck will shake violently when trying to accelerate or brake. Very dangerous when driving on the highway and the truck will not accelerate so that I can merge without being rear-ended. Sometimes it will loose all power so I have to let up on the gas and try again softly and it will slowly accelerate this has also happened at a traffic light that turned green for me, as I was entering the intersection I lost all power and was almost rear-ended. The first happened when I was trying to get into the right slow lane on the highway from being pulled over on the shoulder and as I stepped on the gas and the truck did not accelerate at normal speeds and I was unable to accelerate to speed in order enter traffic in time to not get rear-ended by the car coming up in the lane I was trying to enter thankfully the other driver switched out of that lane.

At 40 to 50 MPH the truck can experience loss of power and severe "shuddering" we have 2 2015's that we purchased last september and both are experience the same issue it's very sporadic seems to happen a few times a week. I'm concerned for the safety of my company as we can be pulling trailers and can not have this type of behavior when on busy roads. Ford knows there is an issue as stated in tsb 16-0041, but they will not attempt to correct it unless their techs see it happen..I have already had it into the shop and they couldn't see the problem. If you look on the internet it appears to be a problem on quite a few 2015's..here is one forum of many http://www.ford-trucks.com/forums/1381159-ford-releases-tsb-15-0088-for-2015-active-regeneration-jackhammer-valves-issue-33.html

2015 f350 6.7 diesel with 46,000 miles that is down because hpop is defective and spreading medal through system. Ford has inspected and said it is because of water in fuel, even though no warning lights or codes are available. Ford pulled sensors out of engine and rejected repair because of tarnish on sensors. The only codes were for (low fuel pressure & reduced power). No other codes. Initial inspection revealed about 3/4 inch of water in water separator but no light or code. The warnings occurred when truck was started and it ran about 100 ft before being shutdown and towed to dealership. This appears to be a common problem since ford offers a repair kit for this issue. Total cost of repair is between $9500,00 & $12,500 dollars and this on a truck which is still under warranty that ford will not honor. The truck wasn't a year old until may 2016 and has been down for over four months because ford will not repair. This is the bosch c4 series pump. *bf *tr *dt consumer stated he had the truck repaired and he sold it.

Engine stopped once in the road pulling a 40 ft.r.v. .intermintley severe loss of power and trying to overheat. Comeing down a 7200 ft. Mountain I lost the r.v. Brakes,engine brakes & the tow haul mode (to help slow down) all I had was the truck brakes going around 80 m.p.h. By the time I got stopped all 4 wheels were smokeing cooking the related parts, rotors, brake pads, calipers,wheel bearings in my opinion.later in a town going slow and stopping the brakes pulled violently to the right, a few more traffic lights then violently to the left. Failing to clean the diesel exhaust filter as needed. Sometimes the wipers come on one time when starting the engine. 3 attemps to fix the engine problems and in my mind it is not fixed yet, most of these problems happened at higher altitudes. All this information should be in the trucks black box, since I could have gotten killed twice I have not let the dealer have the truck again as it is running o.k. Now and I have ordered a new truck because I am afraid of this truck. The dates are approximate, the dealers and I have a copy of the repair attemps . I was on the same roads two years ago with a 2011 f-250 same engine and a heaver load and did not have any problems.

The vehicle is a 6.7 ford power stroke. During a process called regen, where is cleans the diesel particulate filter, the engine would shake violently. It got worse overtime, to the point it started doing it wile I was merging onto interstate, pulling a piece of equipment (9000lb) on a trailer. It was dangerous with the loss of power. I have since traded it back to dealer as ford has said it is normal operation.

Bought truck brand new in december 2014. At approx. 5,000 (still during the diesel engine break in period) while driving thru an intersection in traffic the truck and motor started violently shaking/bucking with the motor making a loud knocking noise- the truck then had a total loss of power in which I was unable to safely accelerate. The truck then went to the dealer in which I was told they could find nothing wrong. The truck now been in an out of the shop numerous times because the problem keeps occurring. Ford released a tsb stating that its normal for their trucks to experience "rough running" during the exhaust regen cycle. The experiences that have occurred with my truck have no correlation to the regen cycle and seem to happen at random times. The truck has become dangerous to drive and pull my horses with as the shaking/bucking is so violent and with a loss of power and unable to accelerate its scary to even attempt to drive in traffic.
