Ford F-150 (2009-2014) :: 2011 XLT Shudder At 5 Kph And Felt As The Truck Accelerates
May 10, 2011
I purchased a 2011 F150 XLT 4X4 Super Crew in early January, since then I have had it into the dealership many times to correct an annoying shudder that can be seen (looking at the steering wheel) and felt as the truck accelerates. The shudder happens around 5 kph or 3 mph and then quickly disappears as you accelerate.
This is extremely annoying in stop and go traffic and is more readily felt if driving up hill. The dealer tried shims in the differential, Installed a new rear drive shaft, U joints and the last attempt was a complete rear end all to no avail.

I bought a 2011 F-150 a year ago. Today was I driving my truck like usual and for some odd reason, it revved up to 3500 and then my truck shooked like I hit a big pump. I'm debating whether I have a faulty transmission or something. I barely touched the foot pedal. I wasn't evening barely putting any pressure on the accelerator and for some odd reason, it revved up that high and something shook my truck. I know a little bit about vehicles, my transmissions are not my thing. I'm gonna' take it in Monday morning to work.

I have had my ecoboost for a couple months now. Overall I am very happy with it but I have noticed a shudder recently when accelerating and when coming to a complete stop at times. I only feel it when accelerating from a stop or when stopping completely. Kind of feels like something slips. I think I recall reading about this before on the 2011 and 2012s somewhere. What is causing this and is there a fix or is it just the way these trucks are?? I can deal with it but it is kind of annoying when driving in traffic.

2010 Corolla 1.8 automatic. Accelerating at highway speed (2800-3200) rpm a low frequency shudder/vibration is felt in the floorboards. Goes away of you let up off of gas pedal. No vibration at idle, runs fine all other times. Most noticeable when accelerating under load (ie going uphill) and at highway speed. Trans mount visually intact. Ditto engine mounts. Cv axles less than 1 year old no rattle upon shaking.

I have a 2011 5.0 screw with 3.73 gears. Today my wife has the truck to haul stuff for her craft show. She calls and says the truck keeps stalling, like she had to keep restarting the truck 3-4 times to back up 10 feet. The dealership we bought it from is going to pick it up and give us another truck to use while they figure it out.

It's a 2011 xlt ecoboost with 14000 miles. Just started getting bad where it literally jars the whole truck. It only does it once. After I'm in 2nd then go back to 1st at a stop, it shifts fine back into 2nd. If I let it warm up for around 10 minutes or so it doesn't happen.

The doors on my truck were leaking water into the cab due to poorly adhered splash shields on the interior of the doors. The splash shield sits between the door shell and the trim panel.
Signs of the leak are water pooling in the groove in the weather strip at the bottom of the opening. Mine were pooling water at the front of the opening and when the door was opened you could see the water running down from behind the door panel.
If you have a water leak along the door opening on a newer vehicle, make sure your dealer checks for this new TSB. It was supposedly only put out in the last week.

Today I was out getting lunch in my Ecoboost When it started making an extremely loud grinding noise from the front end of the truck. My first thought was I blew a turbo. After holding the break and building boost I discovered it was not the source of the noise. Also the truck runs perfect and there is no smoke. I then took it to my friends auto shop and pulled both front tires off to check and see if anything break related came loose. We found nothing. The noise only happens upon acceleration or cruising throttle, as soon as you let off the sound goes away. So after I found nothing I took it to ford and what would cause that, but they assured me that they would have my truck for a long time while they figure out the issue.

Issues:
1. Backup camera sporadically does not come on in rear view mirror. Has already been replaced by Ford dealership.
2. Backup camera settings Visual Park Aid and Guidelines sporadically are set to 'off'
3. While truck is running, start seeing warnings/hearing chimes. Emergency Brake (which isn't set), Engine Overheating, Check 4X4, etc.
4. Truck will NOT start. Won't even attempt to turn over. When this happens, I have a radio but the LED screen is usually blank.
These sporadic issues are starting to seem to be related to the use of the emergency brake. Use of the emergency brake does not always immediately cause issues. Now that I feel like there is some kind of connection, I have been setting the e-brake when I park it (even if not needed) trying to force things to happen because Ford says if they can't make it happen they don't know where to look/what to fix. I can't always make things happen by using the e brake...but am noticing things happen more often when I DO use it and when things happen (like backup camera won't work) setting the brake will make it come on and then I can release it and back up. If it won't crank while the brake is set, releasing it will cause it to crank. The other morning when I had all the warnings/chimes going off setting the e-brake made everything go back to 'normal'.
Yesterday when I came back from lunch I parked and set the e brake (on level ground). Got in it to leave work, left e-brake set, stepped on regular brake and tried to crank....nothing but radio. Called dealership. They had me try putting the key in, pressing the regular brake, and try to move the shifter from Park to N. Shifter wouldn't move. Then asked to turn key to just get it 'active' and try again. Shifter wouldn't move. Asked me to turn the key to crank and try again. Same thing - shifter wouldn't move. Truck finally cranked after I released e brake. Came home, parked and set e brake and turned it off. It re-started right up with e brake still set.

I have an 09 F150 4x4 with 116,000 miles on the clock. I am having an issue with moderate acceleration and felt mostly in 3rd gear. I changed the spark plugs at 106,000 miles with OEM replacements. I have had this issue since about 80,000 miles but intermittently. It seems its starting to get worse as time goes by. The problem is both cold or warm and doesn't happen all the time but now about 80%. Light acceleration is good and full acceleration is great with no issues.
Feels more like running out of fuel but not to the point of stumbling. Possible misfire that is not being detected. No check engine light lit. Tranny shifts perfect. Idles extremely smooth. I was thinking a coil problem but with no engine light, I don't want to try to guess which one. So far, this truck has been awesome and has needed nothing but tires and routine maintenance. I pull trailers consistently and this beast is not abused nor babied.

2010 f150 supercrew fx4
While driving down the highway yesterday at about 65mph I went to change lanes. As I was changing lanes I gave it a little gas. About half way through the lane change truck jerked like I had just been rear ended. I immediately checked my mirrors to see if I changed lanes in front of some body. No one was around. Truck still ran the same. Everything I'be read seems like similar thing happen to others at slower speed.

5.0L ... I'm having one of those moments, you know after you do a mod to your truck and all of a sudden you notice something about your truck that could have been there all along but now you notice it as something new? Ok earlier in the week I had my exhaust resonator removed and replaced with a straight-pipe by a reputable exhaust shop. IMO the work looks to be pretty good for what it is.
That said I have always been nervous about getting exhaust work on any vehicle because it always seems like tampering with or removing the OEM plumbing for aftermarket or custom work tends to develop a vibration at some point.
So here is what I've noticed over the last couple days, when driving my truck it is extremely smooth, almost like glass. When I come to a complete stop say at a traffic light about 1-2 seconds after making the complete stop I feel this slight harmonic vibration in the steering wheel. For those of you that have an iphone it would be like having your phone bolted to the steering shaft somewhere and it on constant vibration if that makes sense.
Just to prove it only happens when I'm sitting still and idling in (D)rive I sat in my driveway with the truck idling, set the park brake and released the brake pedal holding the truck in place in (D)rive with the parking brake. No vibration, smooth as glass engine idle, as soon as I put my foot back on the brake pedal the vibration comes back. It's as if the extra draw of applying the brakes puts an extra load on some sort of accesory drive or componant under the hood and the result is this harmonic vibration.
Just so everyone knows, the vibration is very noticeable to me because I drive the truck daily, most people wouldn't pick it out if I didn't tell them first. Case in point if my wife drives the truck she can't feel it unless I tell her what to look for. There are going to be some of you that just say my truck doesn't do this and has had a smooth idle for XX,XXX miles I believe you but let me know now that I have explained exactly what to look for. Like I said for all I know it's done this since day one.
I have a feeling that the straight pipe might have been welded in slightly longer than the oem section that was removed thus putting more tention on the exhaust and engine if that makes sense, the end result being a slight vibration?? I know that manufactures put these little rubber bushings along the exhaust system on cars/ truck to absorb harmonic vibrations and for all I know my resonator might have been designed to balance out harmonic vibes in the exhaust system as well as quiet down the exhaust.

I have an issue with my new 2011 F150 FX4 super crew with 5.0. I put a Rough Country level kit on the front struts which raised it 2.5 inches and looks great. The issue is that there is a low speed knock heard on the left side and felt through to the steering wheel. The truck has been aligned to factory specs. all bolts have been tightened, the strut has been taken off to check the top mounting bolts. Nothing appears to loose. Can't find anything. Am I forgetting something. Rough Country said it can't be the kit. It has bee used for sometime with no issues.

Been suffering some take off shudder as well as the 55mph shudder and finally took the truck into the dealer who informed me it is throwing a couple of misfire codes (no CEL). Quoted for spark plugs. Looking around the boards, seems a lot of people are seeing premature wear on the ecoboost plugs and have had success regapping or replacing. Any words from 5.0L owners? What are the odds they just need regapped? I'll probably just replace them anyway, but its a good discussion. Also are they are simple to replace as it looks- just pop the coil packs off and they are there in the valve covers?

Just pick up a 2010 FX4 with the 5.4. Noticed at idle with the A/C on 75% of the time my truck is shuddering at idle. If i turn the A/C off it goes away. Common sense is that i know the the A/C draws a lot from the engine but have a shudder like that? The P/O's ESP transferred to me so i can take it in if need be.

Extended cab ecoboost 2x4. Shudders as I come to a stop while in 1st gear. Feels like it's something to do with the transmission. Haven't taken it in yet. Not towing/hauling.

New start for an old problem. 2010, F-150, 5.4, 5.5' bed. Truck is new to me, used 105K miles. Love the truck, got it to tow TT I was having trouble towing with a shorter wheel base vehicle. Has HD towing package, tows great, good power, stable. First trip out with the TT the ole Shudder in 2nd gear low speed reared it's ugly head. I did do the slip joint re-lube with Ford wonder grease.

I was sitting in my car waiting for someone, and noticed that whenever I pull the window button(s) to pull a window up (esp if the window is already up), the RPMs dip and a shudder is felt through the car. What's up with that!? I tried it about a zillion times: pull, dip, shudder.

2010 F150 5.4, 6 speed... I am fast approaching the end for the factory 60,000 mile drive line warranty. I have had the slow speed 0-2 miles per hour shudder since 3,000 miles. The shudder downshifting from 2nd to 1st when stopping. As well as the highway shudder when gradually accelerating above 55 mph (empty and loaded)
The dealer that I purchased the truck from has driven with me several times and experienced the problems. They reflashed the computer at 5,000 miles. it made the shudder frequency double. i.e., twice as rapid. Reflashed again with no change.
I finally called Ford Motor Company, and they were surprised that I had not filed a complaint earlier. They followed up with the dealer.....who's service dept opted not to work on the vehicle again. I am now working with another dealer, and will be starting from scratch.
Long story short. I see that some have replaced torque converters, transmissions, clutch plates, valve bodies, and on and on....

In june of 2014 I purchased a 2012 F150 Harley Edition with the 6.2 for my wife to use as a daily driver. I told her that she could have any vehicle she wanted and she chose the White Harley Truck.
It is a Ford Certified Pre Owned and we took delivery with about 30,000 miles on the odometer.
From the test drive in June 2014 until today the truck has had two distinct issues with the rear end and suspension:
1. After coming to a normal stop (at a light) when you start to accelerate (on green) there is a distinct thunk that is heard and felt. Having owned other vehicles with a slip yoke drive shaft I knew right away that the slip yoke needed to be cleaned and lubricated and that is how the dealer repaired this issue. The repair lasted about 10,000 miles and the thunk started again recently.
2. Also after coming to a normal stop and then accelerating there is a vibration felt until the mass of the truck is moving along at about 20 MPH. It's not a vibration like a wheel/tire is out of balance it's more like the whole vehicle is shaking similar to the Space Shuttle Experience ride at the Kennedy Space Center. The shudder is severe enough that my elderly neighbors asked if the truck "was going to make it without falling apart" when my wife and I took them to dinner one evening. The Shudder is exponentially worse when towing any kind of trailer. I have a tandem axle car hauler to haul a 1992 Jeep YJ to various events and the whole setup might weigh 5000 LBS max which is well under the tow capacity of the truck. To say the shaking is violent is putting it lightly.
When I took it in for service, the dealer told me that it was my fault for riding around with the locking differential locked. I told them nice try and that I know what a locking diff is and how to use it because I have two of them in my Jeep. I then took the service advisor for a ride, made him verify the diff is off and demonstrated the problem without even leaving the parking lot. At that point he acknowledged the condition I left the vehicle with him again. The repair the dealer made was to change the rear differential fluid and called me to say the truck was ready.
I drove back to the dealer again (35 minutes in light traffic) where I was presented with the vehicle. I didn't have to leave the lot before I knew it still was not fixed and pulled back into the service lane. I was greeted by the advisor who then proceeded to tell me it was "characteristic of the vehicle." I was completely frustrated and took my truck with it's "characteristic" shudder home.

Been doing a lot of reading about shudder/vibration on the 2011+ F150's and it seems to all center around the two piece driveshaft found on the longer wheelbases and more during take-off than other times. I have an '11 5.0L 4x4/auto with the 145 wheelbase and the 1-piece aluminum driveshaft and am experiencing a shudder in 3rd gear primarily, most noticeable during light acceleration with medium load (like gently accelerating up a slight incline).
When this is occurring I can see the tach needle fluctuating just slightly (maybe 50-150rpms, just barely bouncing) but I have no check engine light and the only time I have take-off shudder is under hard acceleration which feels like axle hop (which isn't too rare on soft leaf springs with 360hp engines!).
Anyways, this 3rd gear shudder is very soft and nobody has noticed it that has rode in the truck with me, but it sure feels like the old AODE/4R70W trans would when the fluid was getting old and the TC started to shudder during "soft" lock. 5.0L? Certainly could be a miss, though power is good, mileage is great and no CEL is lit...
