Prius (2010-12) :: Vibration At Mid-Throttle When In Slight Acceleration
Oct 12, 2015
My 2010 Prius with 140000km has developed a vibration noticeable anywhere from 50-80 km/hr when in slight acceleration (just over 1/2 on the green bars) with the ICE running. Dropping the throttle or hard acceleration makes it disappear completely - which tells me it's driveline related. It feels like its coming from the passenger side, particularly rear, but it's definitely getting worse and I can now feel it in the driver's door panel so it's becoming a major concern.
My first thought (due to the location) was a bad muffler but it's not any louder. I'm starting to worry it may be a transaxle bearing. I can't see it being a cv joint as there's no noises when cornering and everything underneath looked OK at a recent oil change. I love this car (what Prius owner doesn't?) and I sure can't afford to replace it. It's been babied since day one.

I have a 2010 with about 166k miles. I am getting a slight hesitation at slight acceleration or constant speed. It does not matter if it's on highway or freeway speeds. Now I am not sure if this in junction with me changing the PCV valve, cleaning the EGR pipe, or cleaning the TB for carbon recently. It started happening a week after it though.

Bought a second hand 2010 prius a couple of months ago. Between about 58 and 68 mph I get a pulsating hum and slight vibration that seems to come from the front of the car. Each pulse lasts about a second then appears again in another second. It's there when going straight and worse if I go round a tight right hand bend and reduces round a left hand bend. If I lift off the accelerator it makes no difference.

About 6 months ago, I bought a 2010 Prius III. Has about 108,000 miles. I had my 100k mile service done a couple weeks ago, and since then, he's been running a little off. When I am around 30-35mph, right before the gas engine kicks in, he starts to stutter. It's faint, but I can feel the slight vibration, almost pull, like it needs more power to keep going. Yesterday, while I was waiting in line to leave a parking lot, the engine turned off as usual, but when it started back up to charge the battery, it sounded like the RPMS were up and down, and he was struggling to keep himself on. The cabin seems louder than normal, too. To add to that, the heat doesn't seem to be working properly. When I put my hands to the vent, even at 75 degrees, the air feels room temp and is chilly by the time it reaches me. I checked the coolant level and it was fine. He also has a lot of ticking - particularly around startup and after I shut him off. Is that normal?

My GTI is the first FWD car I've had since 1985, so the issue that I'm having may be just me adapting to a front drive platform. Here's what's happening: when I nail the throttle in 3rd or 4th gear, on or about 4K rpm or above, the car feels as if it's hesitating slightly as the revs climb.
It accelerates fiercely (I have the JB1, and I had the Neuspeed Power Module before it, and it's reacted the same way with each mod), and it's almost as if the front end of the car is lifting and struggling for traction (although the traction control light doesn't come on).
Is what I'm experiencing normal FWD behavior? Is it the beginning of torque steer? I only notice this at full throttle--not noticeable at all at partial throttle. Also, it doesn't happen consistently. My car is a performance package manual.

I have just purchased a 2005 elantra fx and noticed a vibration all the time in the steering and you can feel it in the seat on the floor and peddles, not severe but enough to be annoying. I had the same vibration in my last car a 2001 elantra. Is this normal with these cars, or could it be something like engine mounts as there is a very very slight clunk on acceleration ?

2014 Camry, 4 cyl. 65K ... Wife's car has developed a vibration that is going to be hard to get a dealership service group to troubleshoot due to randomness. I drove it for 30-45 mins today and have this description:
-Vibration, either described as a 'buzz' or a 'high frequency vibration'
-Happens in the 28-38mph range (different points)
-Under very slight acceleration. (hard acceleration efforts produce nothing)
-Can't swear to it, but feel like it is always in 'high' gear
-feel it in 'seat of pants', NOT through the steering wheel
-Is faint on sound, but you can hear something
-Is typically only a second or two
-Is very hard to 'create', but then happens unexpectedly.
-My wife first reported it to me, and I took my son on the test drive today and he could feel it as well when it hit, but couldn't pinpoint it as it comes and goes so quickly, but again, you feel it in the seat/butt more than anywhere else.
I've checked lug nuts to try to eliminate something easy and they are fine.
Since it is relatively slow speeds and under very slight acceleration, can there be a 'solenoid' that is creating a false shift effort, but just vibrates the trans instead? Without any info other than what I have stated above, I'm leaning toward transmission, but again, probably not enough info to go on....

I posted a while back about my 04 5.4 having an issue at idle. I did all the normal things like replace coil, spark plug, etc etc. No change to the issue. It still acts as though it's misfiring on a cylinder and I get codes P0306 and P0316. Finally took it to ford and had a diagnostic check ran. Everything on the top end was in working order. The tech even put a known working coil on 6 and nothing changed. I was told that it's either an intake or valve issue on that cylinder. But no definite answer to problem.
Fast forward to yesterday. I got a wild hair at lunch and went out and started truck. Pulled injector plug off of 6. No change to the way it was running. I did the same for 5, 7, 8, 1, and 2. All of which made a big difference in the way it ran. It was obviously misfiring with no fuel to cylinder. This gave me the idea to swap 5 and 6 when I got home to see if the issue followed the injector from 6. I did NOT. I pulled the plug on 5 and got the obvious change in the way it ran. So there is definitely something going on at cylinder 6 that I cannot figure out.
PCM, bad intake, bad valve? I'm not rich so a trip to ford for repair is gonna have to wait. Truck seems to run fine when driving except for slight hesitation during acceleration.

I purchased a 2010 2.5 Altima with 9K miles in 2011. After @ four months I noticed a slight miss at 30-45 mph upon acceleration. I told the dealership and they said it wasn't throwing a code. After two more visits I again complained about the miss. At this time the service person handed me a "Customer Satisfaction Bulletin" that explained that cars (Altimas, 2009- 2011 with my trans. and engine experience this "SURGE" as they called it AND that it is NORMAL.There is no way in hell that a auto maker would produce a car that does what my car does and consider it NORMAL. Buy the way, there is a "FIX" that was done but didn't work, that involved changing motor mounts and computer programming.

2005 Escape 3.0 with 160k miles. Slight miss under cruise, goes away under slight throttle. No service history known about vehicle. Best to replace spark plugs and coils with Motorcraft parts? And the intake gaskets too? Suggestions for correct plugs?

I have a 2011 RX350 and like car for the most part. Something strange I have noticed is that the gas pedal seams to have some little vibration when I am pressing it smoothly. My foot is constant on the gas pedal maybe 1/4 of the way down and it doesn't feel smooth like other vehicles. I have a 2014 lex IS250 and it doesn't have that vibration. Also had a 2004 RX330 and it did not have that vibration. It is a slight vibration that ruins the luxury driving experience.

I have just over 11K miles on my 2011 and now notice steering wheel vibration & slight shake at 70 mph. The passenger can also feel it.

The last couple thousand of miles I have spent fighting vibrations (especially in steering wheel. Symptoms: When you hit the 65mph mark I am getting slight vibration in the steering wheel. Also passenger chair start shaking substantially more. I assume the shaking is of the whole car, but I feel it the most through the wheel and probably where my brain focuses on.
So far to correct the problem:
- Dealer replaced couple tires which showed excessive weight (the truck came with Michelin HP)
- Wheels were scratched through not careful person, so they have replaced them with a set from a demo
- Dealer balanced wheels 3+ times and done alignment
- Problem was not going away, so I have decided to try different tires and have bough new Michelin MS2
- Discount Tire has done several wheel balances, but seemed that it worked for a day or so
- Meantime also bolts holding lug nuts broke three times while tightening them (don't know if the same one but at three different occasions). Supposedly they have used spec pressure of 80lbs (83 Lexus recommended)
Dealer concentrates on wheel balancing, and is not taking action outside of this. I told the dealer that the problem cannot be wheel related. I think the cause could be one of the three (previous GX470 issues found on internet):
- Wheel bearing in the hub issue
- Drive shaft
- Transmission excluded as vibs are in all gears
- something with steering.
I am awaiting a call from the dealer when the FTS person will at the dealer again so he can trouble shoot the car.

I've had my 2013 Hyundai for about a week now and I feel a slight vibration/shaking when the car is stopped and I have my foot on the brake. When I was in the finance office signing all the papers, etc. The finance manager was trying to sell me the free oil changes for 3 years/tire rotations/filter change for $600. He was adamant that if I do not get all my service done by Hyundai dealer all the warranties are voided. I asked him specifically this question at least 3 times as I was appalled at the notion, and time and time again he would say the second you bring it somewhere else for an oil change the warranty is voided. 5 days later I brought the vehicle back to get my sticker, and I asked the guy at service, he said absolutely not. He said it doesn't matter as long as you have the proof/receipts.

To all 2014 and 2015 GX 460 owners, does brake pedal have a slight modulation or vibration while press it. Feels like ABS but not as strong pumping action.
When I step on the brakes the first time feels normal and then I let go of the brakes, then I press it the second time that is when I feel a slight modulation or vibration of the brake pedal.

Over the past month or so my wife and i have noticed a slight vibration or? I don't really know how to best describe it other than a feeling. The truck has developed this feeling thru the steering wheel and pedals. The best way i can describe it is like a bearing going bad?
It is full time awd and I am assuming it is an awd issue. The truck has about 60,000 miles on it. It can be felt at all speeds. I rotated the tires with no change. My next step would be to go thru the front end, ball joints, tie rod ends, etc. But I really don't think the issue is in the steering. the truck drives straight and no steering vibration.

My 2010 RX 350 only has 35K miles and I've been feeling that the smoothness in the ride has really deteriorated in the last several months. So much so, that even though I could have squeezed another 5K or so out of my tires, I bought a new set...OEM Michelin Latitude Tour HP. I can't say the ride has improved at all. Today, I brought it to the Lexus dealer for a brake inspection, because I was getting a slight vibration in the wheel when braking. Front brake job was needed. I was given a 2013 RX 350 as a loaner. The ride in that car is so much smoother. Should I be questioning the suspension or some other issue that would improve the ride?

I have a 2010 Explorer XLT that I bought in 8/2012 with 7,000 miles on it. I had had a problem with a groaning noise and slight vibration starting at 34 mph, under load. I don't hear the noise if I let off the gas at 34. I hear it a little past 35 or so and it doesn't seem to groan again until about 60 mph or so. I also have a feeling of the all wheel drive engaging when I back out of the driveway, put it in drive and turn the wheel slightly.
I took it to the dealer this week under warranty and he calls me today and says the tires are worn differently all around and that is causing the problem. He says the tires could be out as much as, or as little as 1/16 of an inch and that is what is causing the all wheel drive to catch and also the groaning noise. I understand what he is saying, but I can't believe that is the problem or more would have been written about it.
I asked the guys about rotating the tires and he said it would not matter, it would just take the problem from one end of the vehicle to the other. These tires are not worn like the truck is out of alignment, it is just normal wear. It now has about 21k on the odometer. What do you all think of this diagnoses? The guy says the PTU thinks it needs the all wheel drive and therefore engages it. This truck can also be manually put in 4 wheel drive by flipping the switch.

We purchased a new 2010 Santa Fe Limited in October of last year, and as it stands today, we've put about 19,000km's on the vehicle (about 12,000 miles for my American friends). About 14,000km's in, we started noticing a vibration from the rear under acceleration. When you reached cruising speed (regardless of the speed), the vibration would go away, but would appear under acceleration. What was more alarming was that at slow speeds when making sharp left-hand turns (turning into the driveway, doing a u-turn, pulling into a parking spot, etc), there would occasionally be a loud bang from the rear end. The first time it happened, we thought that we had run over something... actually not but it sure sounded like it!
We took the vehicle into the dealership, and after an inspection they found a rock in one of the rear springs. They removed the rock, applied the TSB to place covers over the springs, test-drove the vehicle, and said the issue was resolved.
The next morning, I was heading out of town to pick up a friend, and experienced a loud bang when I pulled into my buddies driveway. Problem was NOT solved. Called Hyundai again, and made another service appointment. This time with the requirement of having a tech come with me for a test drive.
I was able to reproduce the vibration, which really shocked the tech. At the same time, I was also able to duplicate the loud bang when making sharp turns (I had actually caused it to happen twice when driving around the dealership, but I was alone in the vehicle at the time!), when he concluded that there was probably some binding going on in the drive train. They took the vehicle in, and after looking at it, determined that the coupler in the drive train was defective, and needed to be replaced. They didn't have the part in stock, so they had to order it in; my concern was that the vehicle was unsafe, but they assured me it would be fine to drive until the part came in. I went on a weekend trip with the vehicle, and experienced some pretty severe binding when pulling into parking spots (no bangs, but imagine driving through a lake of molasses) - I had to really give it gas to get it moving into the parking spot - not nice, especially considering what might have happened had it 'unbound' while under throttle...it was certainly not safe, but I survived.
After THREE weeks, the part finally arrived, and was installed yesterday. I'm happy to announce that the vibration has ceased, and I can only assume that the loud bang is gone as well (although I couldn't duplicate that on demand, so I'll never know for sure that it's gone). The Tech did mention that it was a new version of the part, so they just didn't install a new part, it was an upgraded new part.

I bought a 6,000 mile RX back in december and notice the vibration at slow acceleration.
It sounds like it's coming from the rear of the vehicle. It stops when it gets up to speed. I looked for anything lose and don't notice anything underneath.
I'm not too impressed with my local dealer so far to have them look at it. It sounds as if something is loose inside the muffler. It does not vibrate upon rapid acceleration.
