Ford 6.7L Power Stroke Diesel :: 2011 F350 - Losing Power - Rough Noise - Vibrating?
2011 F350 diesel with 10,000 miles. I have been experiencing problems with the truck loosing power, making rough running noise (pinging like an older diesel), and vibrating. As though the motor is bogging down. It usually occurs on small inclines or hills with the truck in higher gears and low rpms. It will also occur running on flat ground 65-70 mph. Had it occur once while turning the truck around in 1st gear and low rpms. Depressing the accelerator will bring the truck out of it.
This problem occurs randomly sometimes a couple of times a week to not at all. Took to dealer and they found no codes and of couse it didn't do it on the hour long test drive I took the mechanic on. However they did say they had two other owners come in with the same complaints, but could not get trucks to repeat the issue. Problem usually occurs in the hotter part of the day, maybe just coincidence. I had seen similar posts with this problem but no conclusions.
Ford 6.0L Power Stroke Diesel :: Whistling / Whooshing Noise On WOT?
The last few weeks, I have been hearing a whistling/whooshing noise on WOT when going to pass someone.
It is coming from the right side of the engine compartment between the turbo and firewall.
At least that is where it sounds like. I have no clue how to verify that driving it. What to check?

My uncle was pulling his fiver to the beach yesterday with his 2011 f-350 6.7. He lost power, the truck got very loud, and there is a very strong stale kerosene smell in the cab. Strong enough to require the windows be down for ventilation. He was able to limp on into the campground and has an appointment with the dealership Monday. The truck has 19,000 miles and is still covered under the extended warranty.

Currently truck is in the shop after having multiple episodes where it lost power. It has 47,000 miles on it. When pushing down gas pedal, just does not want to go. Very slow to shift through the gears and get to highway speed. Turbo was not there, and there was also a hard shift/jerking from 2nd - 3rd. Did notice the traction control sensor kick on a couple of times....which was just replaced since a hole rubbed through the wiring. (took it to Ford twice before they found the problem)
They told me today that the code generator said to look at wiring but they did not find anything (heard that before) and that the fuel is possibly contaminated with DEF. If that is the case, someone is messing with my truck! What I don't understand that if the DEF does turn out to be in the fuel tank, wouldn't we have the problem continuously and not intermittently over a month after driving thousands of miles and going through numerous tanks of fuel? We drive and average of 60 miles per day just for work, half interstate/city.
Ford 6.7L Power Stroke Diesel :: 2011 F350 - Reduced Engine Power Code On Dashboard
I have a 2011 6.7 F-350 Diesel. I bought the truck new and I've never had any problems with it until now. I have a SCT Chip & Tuner. It needed an update so I returned the truck to stock and a code came up on my dashboard that said "reduced engine power" which obviously I thought was Normal because of the modifications done to my truck.
I updated my tuner and returned the truck to a performance tune but this dashboard code will not go away. My truck isn't reading any codes and there's no other indication lights on. The truck has Normal RPM readings but 0 throttle response. No power at all...

The past month or two, my garage-kept 2011 F350 6.7 with 38K miles will shudder on startup for a second or two or three then runs normal. What would be causing that? She is my every day driver, but I don't drive her every day. Seems that the longer she sits, the rougher the startup. Last time I drove her was Monday. Started her up tonight to run to the store and she shuddered for about three seconds.

Took my '11 F350 CC 6.7 Lariat with 31k miles on it into the dealer to have the tranny fluid leak looked at. I noticed this leak a few weeks ago as the bell housing was damp with fluid and the bolts heads on the underside of the poly engine oil pan were pooled with fluid. It is a very slow leak as I have parked it for 3 days and there were no drips of fluid on the ground, just collecting on the grid like pattern on the oil pan. Checked Fluid level and it is also full.
Anyway, the dealer put dye in the tranny fluid and told me to drive it for a few days. I took it back in on Monday and called this morning for an update. The mechanic informed that they ordered a new torque converter and some other parts to be "proactive" because he believes the TC is the issue. I asked if the cab would have to be pulled and they informed that all the work could be done from underneath. Glad I noticed this before the B2B warranty expired because this would have been expensive. I will be THOROUGHLY inspecting the entire vehicle from top to bottom before I hit 36k.

Just went out this morning to start my 2011 F350 diesel and the starter is doing a "chugging" sound. Not spinning the starter at all. Just turned 60,000 miles last week and this is the very first issue that I have had with the truck.
I have put a trickle charger on the battery on the drivers side, and plan to leave it on for an hour or so.

Ford 6.7L Power Stroke Diesel :: 2011 F350 - Air Water Intercooler Leak?
2011 6.7 F350 .... 120,000 miles ....I have been smelling anti-freeze for the last couple of months but have been unable to find a leak. Going through a minor amount of fluid but no indication on the ground ...
Searching deeper today I see the bottom of my intercooler is wet - remove the air hose and there is some fluid. I am assuming there is NOT supposed to be fluid in the air intake hose - correct?!?!
Any thoughts or history on these intercoolers letting-go and leaking internally?

Got the warning on the message center.. 2011 F350 38,000 miles. I am not original owner, has lifetime POWERTRAIN so thinking of letting dealer handle this,,,but..?
With the importance of these cooling systems.. and coolant being in there for approx. 60 months.. I am thinking why pay for test kit or pay dealer to test it and add additive...
I guess I could just buy the oem coolant and distilled water and drain & fill it myself... but can I use garden hose to flush? Or just better to let FORD handle it?
Ford 6.7L Power Stroke Diesel :: 2011 F350 - Black Smoke When Under Hard Acceleration
I recently purchased a 2011 F350 chassis cab with no bed installed. Have a few questions regarding the exhaust system. When I inspected and drove it noticed some black smoke when under hard acceleration, nothing major though. Other that that the truck drove great. Have not got the truck home yet, a friend is going to pick it up and deliver it in a few days. Based on the visible smoke I was suspicious of the exhaust system but I have no knowledge of what the system is suppose to look like. My experience with diesels and for that matter gas engines is mostly from the days of mechanical fuel injected diesels (70's era farm tractors mostly) and carberated gas engines.
My friend stopped by a local Ford dealer and crawled around under a new 2015 Chassis cab to look and compare to this 2011. It appears that the SCR and DPF are not installed on this truck. Where they would normally be is a section of pipe with a section about 2 feet long that is 6 or 8 inches in diameter. Looking at some threads on this site I'm guessing this is a muffler that has been added since the truck is not loud. There is no DEF tank and all the wiring for sensors that would be attached to the exhaust system appear to be tied off to the frame and not connected to anything. The dealer didn't know the history beyond he purchased it on an auto auction and he installed a new rear end in it. Car Fax shows nothing of concern.
My question is should I now be concerned since have determined much of the exhaust system has been removed? I've read some threads and it appears that the only way this can be done and have the engine run well without any codes etc is if the removal is done with some sort of tune. Is there any way to determine who has done the tune? Will it be an issue when take to a Ford dealer for service?
I know if wanted to put the system back to stock would be large dollars, as long as the system runs well and is reliable I will be happy. The anticipated use of the truck will be to pull gooseneck trailer and will probably not see more than 1000 miles a year towing and 5 to 10k total in a year. I drive with a very light foot seldom ever pressing any vehicle to its limits. If still have the truck in 10 years when retire or at least cut back on my work then it may see more miles.
Ford 6.7L Power Stroke Diesel :: 2011 F350 - Lost One Gallon Antifreeze Coolant
Had my oil changed on my 2011 F350, and the tech said that I lost one gallon of antifreeze coolant. Where could the coolant have gone? We could not find a radiator or hose leak. I am afraid that the coolant somehow got into the engine oil, and may have damaged the engine. I have 46000 miles on the truck.
