This vehicle has 42,188 miles to date, and has been down for over 8 weeks due to sensor problems involving the egr and def system. 4 temperature sensors were initially replaced, and then the particulate sensor showed a fault. That sensor was $146.55! as of today, that sensor is bad again and Ford states there is a updated one for $200.99! the emissions warranty runs out as soon as you drive it off the lot! I have spent nearly $800, and this vehicle sits, as the check engine light keeps it in limp mode. This vehicle is maintained in perfect condition. If the epa is going to require these emission standards, then vehicle manufactures should be liable for these costly repairs! I recently found out that there are delete kits to eliminate this issue. However they void the warranty and it is unlawful to do so. I can see why they are doing this. Frankly, I dont see the point in a "handful" of us trying to keep ours running to code, while others are ripping this pollution stuff off. I don;T see the point. However I am totallyl frustrated at a $70,000 pickup that remains broke down. You can't even trade them off if they are having def issues. I read quite often about state, county and city vehicles that are having the same issues, and that keeps them off the road for snow plowing and a host of other duties. This issue needs addressed and resolved. Talk about a safety issue: Driving home in the dark and this thing decides to limp off the road. Always a weekend or after hours. And service shops are so far behind it takes weeks to get in. This is outlandish that the us is trying to reduce emissions while the rest of the planet could care less. What is the point? I am a reasonable person, but I do not see the point. Clue me in please.

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.

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. Consumer stated he had the truck repaired and he sold it.

I have a F350 2015 vehicle, having an engine knock noise and hesitation problems right after the engine knocks. I have experienced these concerns five times. The dealership is saying is a characteristic of the vehicle due to California regulations. There is a tsb to the concern that I am having, but I don't think my vehicle should have the heads rebuilt since I just purchased it back in Dec 2015. What is the state doing to have this concern resolve" I brought it in two days ago to the dealership and since after the 4th time of the engine knocked the check engine light came on they ended up replacing a sensor. I picked up the vehicle from the dealership yesterday and on my way home, the engine knocks to happen again. I am waiting on fmc to call me and tell me what they are going to do now. The vehicle has two other problems a windshield noise at 60 to 70 miles per hour on windy days. They resealed the windshield the problem exists. They are telling me, that unless they duplicate the issue, they can't do anything. I showed them a video that I recorded during the concern happening, but they are ignoring it. I showed them a video that someone else posted on you tube same concern. However, since they cannot duplicate they cannot do anything that is their answer. I also have a problem of the transmission, harsh shift as slow speeds same thing can't duplicate is what the work order from the dealership states. What can I do to have this vehicle looked at for the concerns I am having" it has been in the dealership four times since I bought it.

During regeneration of the diesel particulate filter the truck loses power and operates roughly. This last occurred as I was merging into traffic on the highway during slick road conditions. This could have very easily resulted in loss of traction and/or collision as I was unable to accelerate to speed.

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.
