Ford F-150 (2009-2014) :: 2011 - Shudder At Acceleration And When Coming To A Complete Stop
Sep 27, 2012
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.

I'm trying to fix a transmission problem with my work truck. It's a company owned, 2011 f150 super cab, 2wd, 5.0 and 6 speed auto. It currently has 225K miles. The problem is very random occurring 2-3 times per week, usually happens on start up, and goes away after a hand full of engine restarts. It has happened twice on the freeway, the transmission releases and a complete loss of power and coasts to a stop. At the same time, the speedometer goes to zero regardless of vehicle speed. Normally, when it happens, the speedometer does not read, all the mpg, miles to E, and related meters show bars "-----". The vehicle starts and takes off ok, but when it tries to shift, it just releases and the truck coasts to a stop. It will repeat this for a while.
After several restarts, the truck goes back to normal. This has happened a couple dozen times now. The wrench and check engine light came on during the very first instance, but the auto shop said there were no trouble codes stored. They kept it for a week, and said it never reoccurred. I have a lousy video that shows, when this happens, the trans starts in 2nd, jumps to 5th, then 2nd, then 5th. I am past due for a new work truck and this one is on its way out, but has to last another couple of months! This truck has otherwise been very problem free and well maintained. I'm actually thinking of trying to pick it up cheap, if the repair is not too bad.

I am the owner of a 1996 Toyota 4runner. Recently, when I bring the vehicle to a complete stop, the entire SUV shudders, almost lunges, forward. At times it feels like the brakes are trying to re-engage. Could really use some pointers on this issue.

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.

Was driving to Airport yesterday and out of nowhere got the flashing check engine and shudder/limp mode while trying to merge/accelerate onto the onramp (had to gun it to go around someone who decided to stop on the onramp for no reason). Let off the gas and the blinking went away. Upon leaving the airport I was accelerating again at highway speed to pass and got the blinking light and then a solid CEL. Found my way to a Autozone and got the code read. P0301 Cylinder#1 Misfire. Was suggested to change COP and plug.
Changed COP on the spot and had to drive it home to my tools to install plug. Thought maybe that since the CEL was still on solid after changing that the code needed to be cleared for the PCM to function normally again. Still have shudder when accelerating hard, so thought it might have been injectors so got cleaning service done at Goodyear. Still have the issue. Disconnected battery and performed IDLE relearn just now and it still is shuddering upon hard acceleration. Stumbled across TSB 12-6-4 which speaks to my symptoms.......I do not have the plate which in turn would imply I do not have the PCM update it references.
I have not noticed a misfire nor had an acceleration issue before so this was a surprise to come out of nowhere. I'm going to be calling my dealership in the morning.

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 a 2012 sonata that has issues from day one. ?
New issue is: For a couple days now I've noticed a crackle noise when I break. It is only when I am coming to a complete stop that the noise happens, not the full time i actually have foot on break.
Not thinking it is the bearings. Thinking it may be something within my suspension.

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 have a 2016 is350. I just took off my is250 exhaust and installed it onto the 350. It is an invidia axle back paired with a tsudo midpipe. Since I have made the switch I have noticed several times after braking and coming to a complete stop within a couple seconds the exhaust "pops" usually 1 time and it is fairly loud. This did not happen on the 250. What is concerning to me is that it doesn't sound like normal exhaust popping/gurgling when slowing down or downshifting it is more of a sudden loud single pop after coming to a stop.

I was just curious what the best way to increase initial acceleration from a dead stop is for a 2009 F- 150 XLT with a 5.4 V-8.

Start from the beginning 2011 screw 4X4 ecoboost 46,000 miles, under wide open throttle and over 3,500 rpm I'm getting a misfire, diagnosis "I usually chicken out when I hit 80+ in 3rd". Misfire occurs in 1st, 2nd, and 3rd don't have enough road to try a higher speed or gear.

My last problem was a leaky rear window. In my 11 F150 XLT, whenever I turn the Recirculate on with the main vents, my main vents seem to stop blowing. 2-4 work, but no 1.

I have a 2011 XLT 5.0 V8 with 133,260 miles. I have extended warranty for the next 12,000 miles...which is great because I drive about 400 miles a month... Anyhow it runs great but for one small issue (hopefully) that has been intermittent.
She likes to idle slightly rough in drive at a stop or very low speed, and in reverse at slow speed. If I don't maintain the RPM it will stall and the low oil pressure light will come on, which I imagine comes on because of the sudden stall.
I first noticed this while backing into my garage in the driveway, It would fluctuate in RPMs and if I didn't maintain the gas it would shut off. I took it to the dealer and all they were able to tell me was the Tranny fluid was low and it would cause it to shut off at incline because a sensor isn't detecting fluid in the tranny. I thought this was weird but being as I have never owned an F150, I didn't know better.
It was fine for a little over a month and it started doing it again at stop lights and backing into my driveway. It has become frequent but there is no issue driving at speed and on the freeway. There is no stuttering or shaking and if it weren't for the fluctuating RPM at a stop and the stalling, it would be hard to tell if there was an issue.
All I can note is that there is a clicking sound under the hood, if I remember correctly the last time this happened I was at a 1/4 tank of fuel like I am now, I also feel like it may be a throttle body issue, or some sort of air sensor, I plan on taking it to the dealer but I figure I would get a more informed answer on the forums.
I also hear this is a common issue with the 5.0s... I purchased the truck in December and since then I have only put 250 miles on it.

From everything I have read I can't seem to figure out exactly what the fix is for what feels like brakes sticking after coming to a full stop, then accelerating? I will describe as a clunking and kicking feel, as if power to the rear end is being delayed then kicking in.
From all the posts and replies it seems like a differential issue. Exactly what the issue is and the correct fix? 2012 purchased used with less than 5K miles in 2013, problem has slowly been getting worse over time.

A week ago, I bought my wife a 2010 Platnium White Lariat. (I will post pics later, when it's clean). We noticed that the smell of fuel, was bad after driving it, and coming to a stop, say at a stop sign.
We returned it to our dealer, yesterday, and this what they found. Just though I'd pass it on to you, for problem shooting, and infor to ask a dealership.
This is the quote on the paper we have. "Customer states when filling up or at idle the can smell fuel in the passenger compartment. Smells like coming from the engine area. Leaking at fuel rail. Tightened valve and road test no leaks now".
We were told that it was a "schrader valve". There was NO CHARGE for this repair. So far it seems to be o.k.
The advise we were given was as follows:
1) NO HEET is needed in the fuel tank
2) No Sea Foam, or injector cleaner of any kind
REASON: Was told it would mess up gaskets, and seals etc. I'm not a mechanic, just passing the word that I was told.

My 2012 Prius Two did something odd today that it's never done before. Today, after leaving a meeting, I had two instances where accelerating from a complete stop was met with a delay followed by a jerky and sudden acceleration. This only happened twice out of the dozen-or-so complete stops I made. This only happened on my first couple of complete stops, then never did it again.
Here is some pertinent information:
- Silver Prius, no tint
- Car sat uncovered for about 2.5 hours
- Was 96 degrees outside, not a cloud for miles
- Turned the car on, opened the front two windows for hot air escape
- Turned the AC on to full
- Sat parked but car running for maybe 30 seconds before reversing out of parking spot
- Rolled up windows
- Battery fan was going strong
- No indicator lights came on to suggest an issue
- Happened on my first two complete stops at stop signs
- Never happened again
- Battery fan eventually simmered down
- Have 55,000 miles on the car

My 2011 F-150 Super crew eb has started to have a knock that comes from under the dash in the radio area. It doesn't occur every time it's started. It is 3 or 4 knocks that sound like a plastic gear slipping, then it stops. I am thinking something in the vent/defrost door. Is it vacuum operated or electronic? Any thoughts?

I have had this for a year now. When I first heard it, I thought someone threw something at my vehicle. I would stop then be at the light then about a few seconds to a minute it sounds like a solenoid kicks out or kicks in... its pretty loud, my passengers even question it. I have taken it to the dealership 7 times now and I am getting frustrated as they do not hear anything each time. As I drive with them it doesnt do it... it seems it does it sporatically... Sometimes it does it after I have exited the vehicle and walking off, it goes through its normal electrical noises then clunk clunk... Strange. I have recorded a sound clip but they said they still have to hear it themselves and they believe it has something to do with the elecrical breaking system but they dont want to swap it out as its an expensive part as they want to make sure of it first... I think I am going to take it to another dealer..

My 2006 lexus gs 300 has this annoying issue where if i would accelerate with light throttle from a complete stop, the car would kick and sort of shake.. This happens the most and basically every time when i would slow down at a stop sign with using the brakes, then let go of the brakes and accelerate again, the car would feel like it has some sort of throttle delay and then you feel a heavy push/kick like the wheels are confused..

So the other morning I drive the 140 miles out of town to work for the week. when I pull up to the job site the cooling fans were revving really really high! never heard this before. then it went back to normal after I opened the gate and parked my truck and shut it off. I'm driving maybe 5 miles tops to the job and back to the motel every day. however that is far enough that my heater should be warming up and it's not even coming close to warm. it blows cold air. and to compound that I'm not sure the cooling fans are even working. they don't appear to be. Is there a connection here?

Have a 2011 F150 with the 5.0. 91K miles. On startup-cold or warm-there is a ticking/tapping noise coming from the engine for about 3-5 seconds then it goes away. Happens on every single start. Sound like it's coming from driver side on top of engine, but hard to pin point.
