Ford Super Duty (1999-2016) :: 2015 F250 - Hissing Or Whistling Noise While Accelerating
May 16, 2015
I have a 2015 ford f250 xlt crew cab, 6.2, fx4 with about 1200 miles on it. My questions are, I have noticed a hissing or whistling noise while accelerating. I took to dealer and was told it was the throttle plates not closing all the way.I was told they all do this. Normal? Very annoying noise with windows down. Another noise I have been having is the brake pedal makes a popping noise while applying pressure to brakes. Dealer said brake pedal assembly was out of alignment. They said was out of alignment 1/8". After adjustment within a few days popping started again.

Have a Whistling or hissing sound while accelerating? My 2015 6.2 seems to make this sound while under load. I took to dealer and they claim its the throttle plates not closing all the way. Claims this is normal, but to me it is annoying. Just would like to know what others think.

I have a 2010 F250 extend cab 4x4. While traveling about 70 down the freeway I get a whistling noise. It is usually worse when the wind is blowing hard or behind a semi. Wind makes the noise louder so I assume the noise is coming from the air hitting something. Slow down to 50 and noise goes away. Do not think it is mechanical because when a gust hits the truck it is worse. Checked all the windows, windshield and rubber parts. Where I should look.

I have a 2002 F250 with 189,000 miles. Im having some very bad issues that im trying to fix. The truck idles rough, with fluctuating RPM's. In certain speed reanges it also shakes and runs rough. If I turn the overdrive off the shaking pretty much stops, but it still accelerates pretty slowly. There is also a whistling noise from the front of the truck until the engine warms up, someone told me it sounds like a bad intake manifold? Does that sound right? What could be going on with my truck? All spark plugs and coil packs have been replaced, as well as the fuel injector rails.

2 weeks ago, I purchased a 2015 F250 6.2 with 16K miles. Upon bringing her home, I noticed that there is a buzzing noise coming from the engine compartment after I shut down the motor which lasts approximately one minute (give or take). Since the truck is still under factory warranty, I figure I'll take it to the local dealership, but I'm wondering with the 6.2 has had the same issue and what the issue could possibly be.

Just the other day noticed a whistle noise or a whining noise while I'm accelerating. Sounds like its coming from from the front passenger side,not sure.

2012 F-250 6.2 gas 4X4 SC/SB: when I run WOT, or near that, from a slow speed, I hear a short "hiss" between the 1-2, 2-3, and i think 3-4 shifts. I can also feel that the engine eases up quite a bit during the shift, and it is kind of a slow, soft shift. It has about 2,000 miles on it. I bought it in March 2013 as a leftover (great price!). The door sticker says it was manufactured in 4/2012, so it sat on the lot for quite a while before i bought it. But i don't remember it doing this when it was newer (~500 miles).
With the lite weight of this configuration (it is an XL so it isn't even carrying around 4 speakers ha ha), and me rarely carrying a very heavy load (yet) or towing anything, I rarely have to step on it very much in normal driving... it hardly ever gets above 2,500 rpm unless I am just running it faster for fun.
The hiss and slow shift happen at any transmission temperature. Of course, it never has been above the left side of the "gear" pic on the temp gauge, where it always is after full warm-up. Well, I'm hoping it is just shifting soft like this because it has "learned" my lite-foot driving style (even when I'm in a hurry of course the engine rarely has to work very hard).

Just bought my first Ford. Its a 2015 F250 Platinum. Im at 1400 miles and Im becoming concerned because when I start the truck for the first time in the day, no matter how long I let it sit and warm up I am noticing that on the first couple of miles of driving I hear a high revving sound as I accelerate and it seems to quick shift during those first few miles.
As I continue to drive the high rev sound just fades away and all engine sounds and shifting are as normal as can be and will remain that way until the truck has been sitting for an extended period of time and is cold. I thought it had something to do with tranny temp but this morning I let the tranny warm up to about 115 deg in neutral before taking off but still had the high rev for the first few miles. I have never owned a ford nor have I ever owned a heavy duty truck, hoping this is normal.

Minor noise, and it might be normal. When I have my air on, I get a sudden hissing noise for about 2 seconds, and it happens once every 5 min or so, almost to the second. Not that loud. like a blow-off valve noise, almost. Sounds like it's coming from the passenger dash area. No other ill affects that I've noticed. Not to be confused with the popular wind/intake whistle that some have. Any theories? Almost sounds like a drop of water landing on a belt, and spinning dry. But it happens on dry days too, I think.

Bought a 2014 SD 4x4 in December of 2013 and this is the second time the big girl has been to the shop with A/C problems. First time it was the evaporator about three or four months ago. During the last few weeks of the summer I began to smell something strange (like band-aids) when the A/C was on and it lingered until the next re-entry. ALso, began to hear a slight hissing noise when the compressor was kicking in and out. They replaced the evaporator, smell remained as they said it was the refrigerant I was smelling. About two or three weeks ago the smell got slightly "larger", and last weekend she would not cool. This is the fourth time shes been to the shop with other problems such as the My Touch system..............

I have a 1999 F 250. When I accelerate my AC from the vents changes to the defrost. Other than that it works great and is ice cold. Why it's doing this.

I've got a 2015 F250 with a 6.2 Liter with no compression on 3 cylinders. The dealer just diagnosed it and has not opened it up yet but the mechanic says it is probably a broken valve spring...that it is not uncommon in this engine.
My concern is not repairing the spring my concern is what a "free spinning" piston in 3 cylinders does to the life expectancy of the main and connecting bearings in this engine. I have rebuilt engines in the past and I have bought re-built from auto parts stores and from Jasper and I have never had any last more than 60-70K miles. It seems to me that even with very little mileage on the engine with three of eight pistons jumping around under no pressure that there could be considerable scarring of the bearings or bearing surfaces. I am no expert by any stretch but this is an engine in atruck that has less than 22K miles on it and I ain't real happy about opening it up let alone trusting for the next 280K miles that the bearings have more wear on them than they should have. It was only driven about 20 miles total like this but that is a lot of pressure on a highly tuned and pretty darn precision machine.
This is the newest vehicle I have owned since 1988 and I meant for it to be the last pickup I drive (I drive 'em til the wheels fall off) but I am not overly confident that even if this is a one off problem that it hasn't caused even more damage that won't show up for another 100K miles or so???

I have a 15 F250 CC SB 6.2 4x4 that is suffering from a driveline vibration. Had the shaft checked for balance and it was off. It's a little better now but still there. Checked all the angles and they're correct. Also came up with a curious observation that all CC SB 4x4's have a slip yoke driveshaft at the transfer case while all the other trucks have the fixed yoke. This appears to be my source of the vibration.

Looking for some input on a recent "hissing" noise coming from eng compartment. It's only noticeable during initial acceleration, and sometimes at the beginning of gear changes. I am assuming its tubo and/or exhaust related, as I've noticed a strong exhaust odor in the cab as well. I wasn't under load when the problem started but i was under rapid acceleration. Not noticing any fluids or oils leaking. No warning lights have tripped, as of yet.

I have a 2015 F250 with a 6.2L and want to clean my throttle body. I have done several before on other vehicles but, just figured I would ask before I just jump in there. Cleaning throttle body on their 6.2L?

First tech post for my new truck. I just bought a hold-over but new 2015 F250 XL Supercab 2wd and love the simplicity of no unwanted options. That said, there are two features I am adding. The first is perfectly straightforward, cruise control (swap button cluster and have the function turned on by the dealer). The second is a tiny bit more involved, back-up camera, in mirror display with bluetooth hands-free (I like the simple AM/FM radio because I can work it all with gloves on).
So I basically need three things from the truck and my research has been inconclusive on a couple of things because most of the threads are for 2014 or earlier. I think I can pull switched 12V and ground (pin 1 and 4) plus reverse lights (center, or pin 7) all from the the trailer wiring harness. It appears these are not affected by the canbus load restrictions of other places to tap reverse signal (remember, XL so likely nothing in the overhead console for the auto-dimming rear view mirror). Are there any challenges with this when I do hook up my enclosed trailer or when it is not hooked up regarding the trailer brake controller/anti-sway?
I already found a good youtube video for how to route the wires so I think this is my primary challenge at this point.

Just bought a used 15 F-250 with 57,000 miles, yesterday tried to start it and nothing happened. Checked the starter fuse and it was blown, replaced it and it immediately blew when i tried to start the truck. Pulled the starter and had it tested and it was good, replaced the relay and still blowing fuses. I have got it to start a couple of times but as soon as you kill the engine and try to restart it blows the fuse. What was the fix? Truck had no problems trying to start before this problem started.....

Took delivery of my 2015 F250 in June with 2WD and the 6.2 gas engine. What I thought to be a slow throttle response seems to be more of a quick shifting transmission according to two different dealerships. My 6 speed automatic has already shifted to 4th gear at only 25-30 MPH. My Dodge Hemi I sold never had shifts as quick as this and I think it's to quick. My question is....is there a way to change these shift points so I get more speed before it shifts into the higher gears?

2015 F250 diesel. I am hooking up an air pressure gauge inside the cab to report the pressure on my rear aftermarket air bags. The pressure reading will come from a tap on the actual pressure line, but I need 12vdc to operate the backlight on the gauge. I have found a bundle of loose wires under the steering column, 4 of which are firewall pass-through wires for the upfitter switches. Do one of the remaining wires in the bundle is an accessory power wire? I need a plain key-on accessory wire connection, not a dash-light connection.
I am using one of the upfitter switches to switch my on-board air compressor and a second switch to inflate/deflate the air bags. Want to save the other 2 switches for future use.
