Ford Super Duty (1999-2016) :: 2015 F350 - Hesitates Momentarily On Acceleration?


Jun 9, 2016

2015 F-350 diesel purchased in Sept 2014. When moving slowly such as turning a corner and I have to let up on the accelerator momentarily, when I press down again there is nothing for an unsettling period of time, maybe 2 seconds, as though the engine died, but it didn't and it always comes back. Is there a firmware programming update for this?

Ford Super Duty (1999-2016) :: 2015 - Vibration On Soft Acceleration?

I just purchased a new 2015 F250 SC 8ft bed 4X4 2 weeks ago. I am experiencing a vibration on soft acceleration (I feel it through the floor), by that I mean when there is power going through the driveway, not coasting. I plan on making an appointment with the dealer. New F250 SC LB 4x4 truck.

Ford Super Duty (1999-2016) :: 2015 F350 - Windows Down With Key Remote?

Just got a new 15' 350 XL and going thru the 'setup' button on steering wheel, there is a toggle option for power windows. got out the old owners manual and heres what it does. when toggled to 'on position' and you unlock doors with the ignition key, you can immediately press and hold the unlock button again and both front windows go down automatically. this of course is for models equipped with power windows and door locks. dont know why we need this option but it'll roll your windows down for you from afar.

Ford Super Duty (1999-2016) :: 2015 F350 - Cannot Open Lid On Center Arm Rest

I have a new 2015 F350 XLT. For the life of me I cannot open the lid on the center arm rest. I have read the manual, and I can't open the lid. This is my 5th Super Duty with the last being a 2010. So you would think this would be a no brainer. I can pull on the handle and its not opening. Pry the damn thing open? Is there a hidden lock? Hidden treasure?

Ford Super Duty (1999-2016) :: 2015 F350 Steering Seems Loose And Squirrely

I recently graduated from a 2010 f150 XLT with F250 tow pkg to a 2015 F350 and am not liking the steering. I have owned the F350 for about 2 months and I have about 2500 miles on it. The more I drive it the more I hate the steering. The steering just seems loose and "squirrely" to me. I even took it to the dealership at a 1000 miles saying something is wrong and they said everything checks out. They, of course told me, it's because I'm used to the steering in my F150. I even told them to check the alignment because it didn't seem right.

I don't know if it's in my mind, but I keep feeling/hearing like something is loose on the front end, especially when I brake on road bumps. I thought maybe it was the ABS kicking in, but I don't think that it. I cannot pinpoint the noise and it's hard to replicate it, so it'll be difficult to get that across to the dealer. Any problems with the steering?

Ford Super Duty (1999-2016) :: 2015 F350 - CEL On - Glow Plug Relay?

I have a new f350 with 1500 miles and the check engine light came on. Took it to dealer he said it was the DEF heater. He replaced that part and then it came back on and now its the GLOW PLUG RELAY MODULE. Now for the good part. Ford told dealer that I could drive the truck with the CEL on. Ford stated that they were remanufacturing the glow plug relay and that is was not available at this time and not sure when it will be ready. I filed a complaint with ford, but with little success. Not sure what else to do about this issue.

Ford Super Duty (1999-2016) :: 2015 F350 Diesel - Hard 6 To 5 Downshift

2015 F-350 diesel purchased Sept 2104. When towing my 16,000 lb 5th wheel the 6 to 5 downshift seems to have gotten much harsher in the last few months. About 10,000 miles on the truck, much of it towing. Is this an indication of a developing problem?

Ford Super Duty (1999-2016) :: 2015 F350 - Flush Mount LED Driving Lights

I have a 2015 F350 and with the long dark hours of driving, I want to put some auxillary lights on the front of my truck. I have a ranch style bumper on the front and I am thinking about installing a pair of flush mount LED driving lights. I was wondering, how well they work? I am personally thinking about the rigid flushmount hybrid driving/flood lights with the focused beam.

Ford Super Duty (1999-2016) :: 2015 F350 - Takeoff Vibration Or Shudder Under Load

My 2015 F-350 Super Duty has a noticeable vibration between 5 and 15 mph when accelerating with my 5th wheel. The 5th wheel is heavy--around 14000 pounds. The pin weight is heavy--around 3000 pounds. The Owner's Manual says on page 191 "When driving with a trailer or payload, a slight vibration or shudder may be present due to the increased payload weight..." (This was brought to my attention by my dealer.)

Seeing the thousands of F-250 and F-350 Fords pulling 5th wheels out there on the road, I wonder how many have this "slight vibration or shudder" and what they have done about it.

Ford Super Duty (1999-2016) :: 2007 F350 - Whistle On Acceleration

2007 F-350 4X4 King Ranch... I have the 6.0 diesel. I am on the road to Houston, Tilden and San Antonio TX, and I am noticing a whistle on acceleration. I can change the tone by how hard I push down on the accelerator. I thought it was a radio issue and turned the radio off and got no change. Turned the a/c off, no change. Down hill or coasting, nothing.

Ford Super Duty (1999-2016) :: 2015 F350 - Rear Axle Pinion Seal Leak

I was looking underneath the truck yesterday and saw that the rear end pinion seal was leaking. Looked like it had been for a while. Truck has 35,850 miles on it. Unscrewed the fill plug and a lot of pressure is released. So I'm assuming the breather is clogged somewhere along the line. I have an appointment at the dealer on Friday to see whats wrong. What is supposed to be at the end of the breather tube? Mine has a barbed 45ish degree fitting on the end of it. Its a SRW by the way.

Ford Super Duty (1999-2016) :: 1999 F350 V10 - Loss Of Power / No Acceleration Over 2500 RPMs

Truck sat for 1 1/2 years. Changed filter and put in 15 gallons of fuel. Had maybe 1/2 gallon old fuel in tank. MAYBE. Fixed fuel line because it wasnt getting fuel and it fired right up and idles great.

Truck has no acceleration over 2500 (or so) RPMs but idles fine. This is depending on how hard you push the pedal of course.

If you drive the truck normally like a grandmother it seems to be ok. As long as you dont need a passing gear or need to accelerate more than 1/4 pedal

If you try to push the pedal to get the next higher gear it will sometimes hit the gear fine. IF you floor the truck it will totally lose acceleration. Then the truck will run like crap even slow for a good while. But then it will clear up for the low end. Then you can drive it normally. Then when I think I can test the upper end I get the same thing again.

Ford Super Duty (1999-2016) :: 2006 F350 - Serious Grinding Noise During Acceleration

My 2006 F350 is giving me grey hairs. I'm trying to figure out what's going on with it. I have been getting an occasional (more often than not) grinding noise from what seems to be the front of my truck. It will do it from a stop, under light, moderate, or heavy acceleration. Doesn't matter. If I let off the throttle momentarily it will stop until it shifts and will grind again through all shift points it seems.

Logic says it's got to be the wheel bearings or locking hubs. I recently did both on both sides to no relief. Because this is an 06 it had a different hub set up then the previous years which I've read a lot of info about (needle bearings). It doesn't make a lick of difference if hubs are locked or on auto. If in 4x4 (ESOF) or 2wd.

As mentioned I replaced both wheel bearings with FORD parts and both locking hubs From FORD as well. (Small fortune). Axle u joints seemed tight. Greased me up but no play.

Ford Super Duty (1999-2016) :: 2000 F350 7.3 2wd Dually - A/C On Hard Acceleration Only

I have a 2000 F350 7.3 2wd Dually - that only only produces cold air conditioing on hard acceleration only stays on for a few minutes then falls away.

The temperature is cold when its going. I've checked the levels and its gased OK. There is no voltage to the clutch on the compressor when it is not working. So I take it, that it isn't the clutch shim/spacing.

If I accelerate hard it comes back immediately. Whether I am going slow at 1500rpm or doing 70mph at 2500rpm - Uphill or downhill. Its seems to need a substantial amount of Turbo boost for just a few seconds to turn on.

I actually bled the system a little and its made it worse. Stays on for a shorter time and isn't as cold. However the low pressure side is still on the high side at 50psi when running.

Its done this for approx 2 years and its getting worse.. And now its really hot outside.

Ford Super Duty (1999-2016) :: 2003 F350 - Revs Fine But No Acceleration

2003 F350 5.4, 4R100 trans.... I've had this truck parked for a few years but want to get it into service for farm use.

In park or neutral, it revs great, idles a bit rough but not terrible. But in drive under load it I can't get it above 1500rpm most times unless going downhill, and then it shifts very late, and I have to get it up to 3500rpm and then let the throttle off to get it to shift. It does better in 4Lo with shifting, but it's still very sluggish.

Now it says to check fluid level in Park at idle. When I do this, I just get fluid on one side of the dipstick, not a full dip as you'd see on an oil dipstick. And the wet on the fluid goes up past the hash marks quite a bit. I'm use to seeing the dipstick get oil all the way across, and then a bit higher just up the edges, but have always read it at the full cover point.

I suspect low fluid, but I'm not really sure with the way the stick reads. I was thinking of draining it all and then filling to spec as per: [URL] .... but have a long drive to go get MerconV.

Ford Super Duty (1999-2016) :: 2006 F350 Shuts Down While Driving After Hard Acceleration

I have an 06' f350 6Ltr. Over 300 k. Good shape, i have owned it for about a year. My first diesel. Last week it wouldnt start, had a 1/4 tank. Read about problems with other trucks with a broken pick up on fuel pump. So i filled the tank and it started. Next morning used command start and it ran for 1 minute then shutdown. took about 5 minutes of manually turning it over and it fires up ran all day. Does this almost everyday since and now shuts down while driving after hard acceleration and surges under acceleration when on incline or underload. Changed fuel relay, fuel filters. Researched and asked around but getting mixed opinions. I am mechanically inclined but this is a little beyond my scope of trouble shooting and id rather not start throwing parts at it.
