Prius V :: High Frequency Vibration At Highway Speed?
May 26, 2012
My Prius v has 1300 miles. I didn't notice at first but now I notice a constant high frequency vibration in the car, especially at highway speeds. Took car to a tire shop and had tires dynamically balanced, same problem. I think it must be the toyo low profile tires or its in the drive train and just inherent to the hybrid system. Seems to be the same whether in eco mode or ev. Vibration is the same on smooth or rough roads. Dealer service manager says he is not aware of any problems. Suggests bring car in for a test drive and compare with another new one.

This has been happening for the past 6 months or so. I recently had new ball joints, 4 wheel alignment, and 4 wheel balance. Even with this I'm noticing a very slight high frequency vibration at highway speeds. I noticed on one of the front wheels that a weight fell off, so this might explain the high speed vibration.
However - When I'm starting at 0mph, and accelerate to say 50mph for example, the car vibrates rather substantially as the speedometer moves from around 25mph to just past 30mph. After those speeds it goes away.
I've also noticed that it tends to be worse if I'm going up hill, which, according to the laws of physics, would tell me that going uphill would put more pressure on the front end, given it's heavier with the engine there. If I'm going downhill it vibrates much less.
When I drive I tend to not accelerate quickly, meaning, I don't 'punch' it, and accelerate gradually instead. If I'm driving on a level, well-paved road, and accelerate quicker than regular, the vibration seems to not be as heavy.
Any other tests for this? Struts, control arm, steering knuckle, drive shaft ?

Had a long trip with the X this week and noticed a weird vibration up at speed. Anything before 65 mph and the truck was smooth, higher than that a medium vibration developed. Its frequency increased with speed. Never got the truck over 70, but the vibration was there enough to rattle change in the cup holder and the rear view mirror. What it might be? I was thinking a hub bearing... 2000 Limited 4x4 PSD ....

I have a 2015 RX350 with 25k. New tires, two road force balance by two different dealers and I'm still getting a high frequency vibration mostly in the seats above 60mph. Dealer cannot find any issues.

After driving for 30 minutes on the freeway, my Sonoma develops a high freq vibration that seems to increase after it starts. lessens a little as I slow, but does not go away until after the car has been parked for a while, but not as noticeable under about 30.. I have experienced this the last three days on my commute to and from work. Did have the breaks checked. I did have a clunk sound when i released the brakes at a stop, but that went away after the first brake check where they did not find anything, but just cleaned out the dust and readjusted. The vibe is pretty strong and makes me nervous to drive.

Just got my 2014 SCREW 6.5bed with eco boost. Truck has a high frequency vibration very noticeable at 45-55 MPH. So bad the rear view mirror is blurry. Took it to the dealer and they said the e-brake was dragging and fixed that and said the vibration was gone. Not gone. Did some searches and found a number people reporting vibration issues possibly related to drive shaft issues.
Took this video of the slip yoke at the T-case idling in first gear, sent it to the dealer and they said that's normal. I don't think that looks normal. Does that looks normal?

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....

So I'm at my wits end trying to locate (and fix) a loud, high frequency rattle noise inside the engine compartment.
It can be heard when applying the gas pedal a certain amount. In other words, I can "find" the noise and maintain it at a certain rpm.
The noise is coming from the back of the engine near the firewall. It feels and sounds like it's coming from the throttle body plate and vibrating the gas pedal. I cleaned the plate and it isn't loose.
The issue doesn't seem to be affecting engine performance.
The sound is noticeable while driving (under load). When in park, I can find an rpm where the throttle body seems to take a heavy wave of vibration from the engine and hum (but not nearly as loud as while driving). Issue existed before I put on new motor mounts, and still persists after replacing all 4 (although the vibration and noise are reduced).

When I test drive the PIP, I kept hearing a high frequency pitch noise whenever the car was accelerating. It almost sounds like when you lightly touch the trigger on a cordless drill. Sales guy and my wife couldn't hear it, but I do have extremely sensitive hearing.
A quick search didn't reveal anything, so I am wondering if this is a problem, or maybe part of the pedestrian warning system (although it happens at higher speeds as well).

Ever since the day I bought the car, it has had a highway speed pulsing vibration. This vibration manifests once you cross about 90kph, and pulses like a sine wave.
Think of it like this - OOOOOOooooooOOOOOOooooooOOOOOOooooooOOOOOO - where big O's are vibration and little o's are absence of vibration.
I have had the wheels and tires rebalanced several times on various machines over the years in attempts to rid myself of it. The original owner had theorized that the car was so heavy and had sat on its aftermarket rims in one spot for so long that the wheels had bent, which does not appear to be the case. The dealer has experienced the symptoms but cannot find a cause...though I fear they are less knowledgeable about the car than I am. I note that several people on the forum have had vibration issues due to drive shaft bushing failures...but in skimming the relevant threads, none of those people characterized it as a pulsation OR a constant issue that I saw.
I wouldn't say the pulsing was fast...think 4-5 seconds of vibration and then 4-5 seconds of peace.

I bought a 2004 Hyundai Santa Fe 2.7L AWD about 5-6 months ago. It has close to 120,000 miles and has a terrible vibration at highway speeds. It starts around 55-60mph and gets increasingly worse as speed increases. The steering wheel originally vibrated quite violently, but after changing the "front axles" it resolved only the vibration in the steering wheel
I took it to a local shop we trust, they changed the "front axles", all spark plugs, ignition coils, timing belt, transmission fluid change, and a o2 sensor.
I changed out a serpentine belt, tensioner, and idler pulley (due to a squeak), another o2 sensor, and tried to change the transfer case + rear differentials fluid. I couldn't change them because the fill plug was very stuck... we used a propane torch and a large socket wrench.
Anyways, after the front axles were replaced, the steering wheel got significantly better, there is however some vibration through it. After they were replaced it did not fix the vibration shaking the whole car. I've noticed that when you let your foot off the accelerator all the way, the vibration stops. When you step on the accelerator again it starts shaking very bad, and then begins to get slightly better. The vibration has a rhythmic timing to it. It seems like it pulsates stronger, then softer every 1/2 second or so
Also I have had the wheels balanced 3 times. I doubt it's the tires, unless a tire is out of round. My rotors also do not seem to be warped. When I brake, there is no shaking/shimmying. I was wondering if it could be the engine mounts? This vibration is very annoying, since I have to drive long trips sometimes. Other than this problem I like this car and would love to see it fixed.

This is on an 04 Excursion, 4x4, 6.0 SPD. I have started experiencing a vibration at highway speed, 60-70 mph. After 70 it smooths out a little but still noticeable. I've replaced both rear tires and still have the issue. When I put my foot on the accelerator I can feel it more but as soon as I let off it drops off dramatically. I am thinking u-joints, which will be replaced this evening...

My Prius just reached 200000 km this week. I bought it at 180000 km 2 years ago, I don't drive it that much simply because I work from home.
Today, a sunny day, 0 degrees, the check engine just lit-up. I opened the hood and checked fluid levels, all OK. I started it and listened to the engine, running as usual. However, when the motor stopped (hybrid ON), I can hear a high frequency noise. I don't remember hearing this noise, but I don't think I ever opened the hood with the engine Off but powered On.
How can I get the check engine code ? I assume I need a connector, right ?

Last week I posted about dropping my car off for service and the dealer finding that all four of my wheels were bent, causing vibration at highway speeds. So I spent a couple hundred dollars and had them fixed.
Car still vibrates at highway speeds...
I feel the vibration in my seat and throughout the car at about 60+mph. The faster I go, the more noticeable it is. I can even hear it.
Dropped off at the shop. Shop called me back stating that the vibrations are being caused by the two tires that need to be replaced.

Our FWD Santa Fe Limited had a very noticeable vibration that started around 60mph. Oddly, the vibration will sometimes come and go while cruising at a constant speed on the highway. We went about 30k miles before we had time to get it into the shop.
I asked them to rotate and balance the tires and the vibration was noticeably reduced...initially. Now it's back!
The car has ~65k miles. All 4 Kumho tires match and I believe are original from the factory. I have kept all tires inflated properly.
Our car has the optional 18" wheels. Is it common for these to bend? What else could be the cause here?

I have a 2004 2.7L V6 GLS Hyundai Santa Fe AWD that I purchased about a year ago. The car has about 114,000 miles on it I believe. My problem is that I have an annoying vibration at idle and at highway speeds of 60-65 mph. The vibration decreases somewhat towards 70 mph. The vibration at idle is usually present, but sometimes vanishes for no apparent reason. The car is very smooth below 55 mph, but when around 60-65 mph becomes quite violent at times. The side view mirrors shake very badly and the vibration can become tiresome.
Originally the shop believed that the front axles were the culprit and replaced them – this mitigated some vibration felt through the steering wheel, but not much of the vibration throughout the cabin. The wheels have been balanced 3 times, alignment checked, and wheels do not seem to be bent/dented. (The tires were road force balanced)
In addition I have also had the following work done:
-2 oxygen sensors replaced (both post-catalytic converter)
- 2 Catalytic converters (replaced to pass emissions)
-Timing Belt Replaced
-Serpentine Belt Replaced
-Idler Pulley and Auto-Tensioner Replaced
-Ignition Coils Replaced
-Spark Plugs Replaced
-Transmission Fluid Change
-Oil Changes
-1 Tire Replaced (Sidewall Blew Out) (Michelin LTX M/S2 Tire)
-Air Filter Changed
-Crankshaft Position Sensor Replaced (It was Corroded Away)
Why the car is vibrating so that the mechanics can check it out. One idea I have could be the engine mounts – this would explain the vibration at idle (in park). I drive about 10 hours a week on the highway at the speeds that cause this vibration.

I wanted to believe I had rid the car of the steering wheel vibration when I lowered the Psi in the tires from 46-50Psi to the 35Psi it should have. However, the car still has a vibration in the steering wheel when going highway speeds accelerating up gradual hills or when accelerating out of a sweeping turn at highway speeds. It is very noticeable, you can see the hands on the wheel shake. Passengers don't notice it. I had my brother in law drive it without mentioning to him and he noticed it as well.

Today I caught a deal on a 06 F-150 with the 5.4l. I noticed a slight vibration that comes and goes at highway speed (65-75), when I got home I jacked the front end up and checked everything out. The right front CV axle is still engaged with the tire when it is out of 4 wheel drive, I can engage the 4wd and everything locks in and works as it should. My understanding is that the axle should spin free and independent of the wheels when in 2wd? How would I go about troubleshooting this?

Getting some vibration at high speeds on the highway, and when I changed my wheels, I noted that there seems to be some free play in the ball joint on the end. Is this normal? Can I replace just the end of the tie rod?
