Ford F-150 (2009-2014) :: 2010 - Clunk / Lag On Takeoff From A Dead Stop Only

2010 F150 XLT FX4 5.4L Crew Cab Medium box, nice blue truck, lacking on chrome though.

My friend has a clunk/lag on take off from a dead stop only. Drives fine down the road, but when taking off from a complete stop, you step on the gas, and nothing happens for a second, feels like it lags, then clunks, gives a jerk, and takes off.

From talking to other newer Ford owners, seems like a common problem.

Ford F-150 (2009-2014) :: Erratic Throttle / Surging When Moving From A Dead Stop Through Low Speeds

I have a 2009 F150 4x4, XLT crew 6.5' bed, 5.4 engine. The truck has a very strange erratic throttle behavior from a dead stop through low speeds, shifting seems very strange at low speeds too.

Dealer tried re-flashing the computer, but that didn't fix it. They talk about some valve that sounds to me like it's similar to an EGR function, but I cant remember what he called this valve. He explained the issue as exhaust gasses that are to be recirculated and burned, but the valve is opening at the wrong time, or stuck open or something so it feeds the fire so to speak.

Does any of this sound typical or common? Is this something that's hopefully easier to do than a spark plug change on a 5.4?

Ford F-150 (2009-2014) :: 2010 - Shuttering When Accelerating From A Stop

I have a 2010 F150 Xlt super crew with a 4.6L. I've noticed lately when I start from a full stop the the truck has a small shutter or hesitation before it starts accelerating. Its barely noticable but it is there. What it could be? I had the tourque converter replaced just before my warranty was up, I've only put 30000 Km on it since. Was wondering if it could be the cause.

Ford F-150 (2009-2014) :: 2012 - Engine Started Making A Chirping Noise When Accelerate

I have a 2012 3.5 eco boost. It has 82,000 miles. I just purchased a large travel trailer. That is the first thing I have ever towed. When I was accelerating onto the interstate the engine started making a chirping noise.( not the normal turbo whistle). It went away when the rpms came down, and now every time I accelerate, it makes the same noise around 2000-2500 under load.

Prius (Gen 2) :: Unusual Grinding Noise When Accelerating From Dead Stop

I'm experiencing an unusual grinding noise when accelerating from a dead stop but only in this specific situation.

1. When battery is at a low state of charge and the AC is on, therefore, whenever I slightly step on the gas the engine will immediately start.
2. Only under this condition, when I slightly press on the gas and the engine will start to charge the battery and propel the car at the same, there is a slight grinding noise coming from the front of the car. I don't know what this noise is, it sounds like gears grinding, it's very light though.

I know it's not the brake accumulator noise, because that's a whole different sound, and also this only happens under the condition I described above. When battery is low and ac is on, and the engine will need to start right away even when gas peddle is slightly depressed.

The best way to describe the sound is if you were to take a soda can and cut it in half and rub the two halves together (the edges) it sounds like that.

Also, there are no lights on the dash. It's a 2009 with about 73,400 miles.

The transaxle oil has already been changed maybe 10,000 miles ago.

The noise started recently, at least I only noticed it recently since it's summer and I have the ac on much more. There are no drivability issues, but the thing is, this noise was not there before, I know I'm not hearing things. You know when you drove a car for quite some time you will naturally know what sounds are normal and what sounds are new.

Volvo - XC90 :: Thump Noise When Accelerating From Dead Stop

Sometimes, when I take off from a red light or stop sign, my car makes a thump. This feels as if it is under the car, not a transmission shift noise. It would seem to me that it has to do with exhaust or fuel???? I am guessing.

Audi - A6 :: 1998 - Banging Noise When Accelerating From A Dead Stop

I have a 98 Audi A6. Immediately when I hit the accelerator from a dead stop I hear a slight bang that seems to come from under the car in the area under the front drivers seat. It only happens when I hit the gas and the car starts forward. I'm not putting the pedal to the floor either, just a nice gradually start from a dead stop. This is the only time that I hear this noise, nothing while driving or making turns. The noise sounds like when you might squeeze and empty tin box! that distinct bang you hear. What might this be?

Elantra MD (2010-15) :: 2013 - Click Noise Mainly Happens When Accelerating From A Dead Stop

My wife and I are new Elantra owners, car is just about to hit 9000 miles on it. I don't know when the noise started happening, but wasn't too long ago. My wife is okay with it, but as for me I find it rather annoying that the car is so new and already making noises. I call it a click but she describes it as a thunk.

Here's the details. The car is an automatic for starters. The noise mainly happens when accelerating from a dead stop. I'll be at a red light and when it turns green, I let the brake go and gently step on the gas and click...there is the noise. Its just a single click, loud enough to annoy me and loud enough that I could hear it when the radio volume is set to 12 or so.

It has also happened mid driving when I release the gas pedal to slow down without using the brakes. Right when I release it, I hear the click...once again a single click.

Now I have taken it to the dealer as a concern because that click wasn't there when I bought the car. They told me it was normal and after waiting 2 hours for a simple oil change to be completed I wasn't ready to argue with them. But I am getting to that point that I'm ready to argue with them, considering the car is so new and still under the warranty.

Honda - CR-V :: Odd Noise That Sounds Like Wheel Bearing When Accelerating From A Dead Stop

I am going to buy a cheap 2004 CRV from work. They think it needs a wheel bearing, and it might.. However I think the sounds we are hearing is a bad motor mount. When accelerating from a dead stop it makes an odd noise that sounds like a wheel bearing, but it is quiet at speed and while jerking the wheel.. There is no weerrweerwerrr... In Drive if you have your foot on the brake, and hit the gas the motor rocks back further than I think it should. After looking at the mounts themselves though, the only one that looks bad is the driver’s side trans mount (near the air box). It looks like the rubber is broken.. So If that is my bad mount would the motor still rock, or could I have another bad one somewhere??

Hyundai - Sonata :: 2005 V6 - Creaking Noise From Left Front When Accelerating From A Dead Stop

This auto has 143,000 miles on it. I recenty noticed a creaking noise from the left front when accelerating from a dead stop. The shop I have used for 15 years said that the motor mounts are deteriorating and should be replaced. I trust the guy but would like to avoid the $1,400 repair. There are no symptoms other than the ocassional noise.

What is the downside of ignoring his recommendation? What other symptoms can I expect if I delay the repair? Can this be a serious safety issue? I plan to keep the car for another two years unless I bite the dust first or the engine falls out.

Ford F-150 (2009-2014) :: Strange Noise During Accelerating

This has happened about half a dozen times while accelerating. It sounds sort of like it's between a scratching noise and a rattling noise. It's only happened at highway speeds 50-60 mph while accelerating and will stop when I let off the gas. There have been a few times that i can get it to come back if i step on the throttle again, but will not duplicate every time.

Ford F-150 (2009-2014) :: 2011 - Swoosh Noise After Accelerating?

I have a 4x4 2011 5.0 f150 with 65k miles. Bought it 4 months ago. I have noticed it makes a swoosh or air sucking noise for a couple of seconds after acceleration and will do it while driving. It is not constant but comes and goes. I have not checked codes. Other than that, really like the truck.

Ford F-150 (2004-2008) :: 2005 - Clunking Sound When Accelerating From A Dead Stop

Bought an 05 FX4 SuperCab in May - been in shop twice for a "clunking" sound when accelerating from a dead stop. Dealer says it's "operating as intended" and that no damage was being if I continue to drive. I thought it was a rear problem with the limited slip. Dealer says it's the tranny and that Ford is looking into the problem (apparently quite a few are coming back). She runs smooth and shifts fine once she gets going. Just starting from a complete stop feels painfully wrong.

Ford F-150 (2009-2014) :: Severe Vibration And Chirping Sound

Bought my 2009 super cab with 6.5 bed little over a month ago. It has the 4.6 3v. A couple weeks after I got all the symptoms of a dry slip yoke. Thumping at stop and start. Shortly after I also started getting a very bad vibration the got progressively worse during acceleration. Felt like the truck was going to bounce off the road. With the vibration there was also a loud chirping noise from underneath. Thinking this was related to the skip yoke problem I pulled the driveshaft and lubricated the yoke with CV joint grease my dealer gave me since they didn't have the Teflon grease.

Truck was fine for a couple weeks. No thumping no vibration no chirping. Last week the vibration and chirping came back just as bad. I got the ford Teflon grease and pulled the driveshaft again. The very next day the vibration and chirping came back. No thumping or other noise like before my initial grease job. When it starts shaking I stop and shut the truck off. Usually once I do that and wait a couple minutes I'm ok. Only happens intermittently. U joints?

Touareg :: Engine Lag On V8 When Accelerating From A Dead Stop

I recall some folks (with certain VIN#s) getting a TSP for correcting the lag when accelerating from a dead stop. I asked my dealer about it during routine service several months ago, but no fix at that time.

Ford F-150 (2009-2014) :: 2013 XLT - Brake Grinding Noise Before Stop

I have a 2013 XLT Scab that has been in twice now for a low speed to stop brake rubbing or grinding noise. The first visit they turned the front rotors and scuffed the pads, which seemed t fix the problem for about a month. The second visit they repeated the same process on the rear and the problem was good for about two months. Today while driving I noticed the noise, probably worse than I have ever heard. It seems like after about 20 stops the noise gets quieter. I am taking it back for the third time and I am hoping they will fix the problem for real this time. I am tired of burning my gas to get to the dealer and then having to ask my salesman for a loaner car. Other than this issue I love the truck.

Ford Super Duty (1999-2016) :: 2006 F250 - Intermittent Loud Chirping Noise

I have a 2006 f250 lariat 192k no mods except k&n filter everything is stock. I have 2" pro comp level kit and a scan gauge 2 nothing fancy! Well the other day I noticed my truck was chirping like a Chirp chirp chirp...... Chirp chirp...... Chirp chirp chirp! It goes up and down with the rpm's but it's comes on and off only when the engine is up to running temps the belt does squeak during warm up but I don't think that's it, it's coming from the back of the engine I'm sure of it because I used a paper towel tube and listed right in the turbo hpop area on top of the engine but it's too hard to tell I can't find exactly where it's coming from, some people I've had listen think it's a belt or pulley or tensioner! But I'm not sure if it is because I've sprayed water, and wd40 on the belt and pulleys with no change!!! I'm afraid it's a lifter or something inside the engine yet it's too loud and pronounced to sound like it's coming from the inside! I'm just lost!

Lexus ES 2013+ :: Hesitation When Accelerating From Dead Stop

Our 2015 es350 with 2,500 miles hesitates when accelerating from a dead stop, such as from a stop light. We are told this is to be expected with this vehicle. The dealership test-drove the car and say there's no problem. But this hesitation is unlike any other car we've experienced.
