Prius Plug-in 2012-15 :: High Frequency Pitch Sound
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).
Prius (2010-12) :: Check Engine Light Just Lit Up / High Frequency Noise When Motor Stopped
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 ?
Prius (2010-12) :: High-pitched Electrical Humming Sound From Hood In Ready Mode
My Prius IV with about 10K miles started to emit a high-pitched electrical humming sound under the hood when it was in Ready mode. It did not have this sound before. I opened the hood and found the sound was coming from somewhere around/under the engine area. I want to know if this is normal on Gen 3 Prius? I have seen post on the same noise in Gen 2 Prius but the posts (thread) stopped without a resolution.

247,000 miles on '98 Toyota Camry as of last summer, car owed us nothing. Suddenly lost oil a month after regular oil change, ruined engine. Mechanic found used engine from totaled car (w/ approx 65,000 miles). Current problems:
1. speedometer/odometer not working,
2. heater/blower stopped working this week, blower makes a LOUD, HIGH FREQUENCY sound, sort of like a siren.
Was hoping to get another 2 years from her considering recent cash outlay. The mechanic couldn't figure out issue #1, and he hasn't looked at it since #2 started this week. I guess we can live w/ issue #1, but #2 has to be fixed ...
Renault - Clio :: High Frequency Noise After Few Seconds When Start The Car
When I start the car, after a few seconds starts a high frequency noise. The noise is located in middle right low part of the car. Here is the recording of the sound: [URL] ....
The noise gets stronger after 14 sec of the video- when i get closer with recorder,.. And the image of the possible location: [URL] .... The image is near fuel tank, but doubt it has to do with the sound.
Prius V :: High Frequency Vibration At Highway Speed?
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.
View 7 RepliesAccord :: Throttle Body Vibration - High Frequency Rattle Noise Inside Engine Compartment
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).
Prius (Gen 2) :: Low Frequency Noise / Squeal When Turning AC On Or Off
Have a 2008 with 23,000 miles on it. Recently, I noticed that there is a low-frequency noise (squeal?) that lasts for several seconds when turning the air conditioner on or off.
View 11 RepliesGen 2 Prius :: Too Much Radio Frequency Noise Generated
I have a very long commute, 60 miles each way and 1 hour minimum. I installed a low end Cobra 40 channel CB radio to pass the time and to get traffic information. The antenna was purchased and trimmed to my car from a communication store which carries CB radios. My problem is, there is so much Radio Frequency noise generated when the Prius is put into drive (not even driven and without the gasoline motor starting) that it is picked up by the antenna and makes tons of static on the radio. The radio is virtually useless.
View 7 RepliesGolf/GTI VI :: 2011 Car Vibrates Mildly At High Frequency
I have a 2011 GTI with about 30k miles on it.... A couple thousand miles/couple months ago I hit a pothole on the highway.... it was a very sharp impact... the sidewall of the tire blistered and the rim was bent as well.... I got new tires and the rim fixed but it still feels like there is something wrong
During the 30k mile service at the dealer I brought it up and they balanced the wheels but didn't see anything wrong... I've had it balanced/aligned a few times since but it doesn't correct the issue... neither the tire shop nor the dealer was able to see anything blatantly wrong
It feels like something is "loose" and the car vibrates mildly at a high frequency... not just in the steering wheel... the vibration is mostly noticeably at higher speeds but the "looseness" can be felt at just about any speed...
At this point I've pretty much ruled out balance and alignment so what else could it be? Wheel bearing? Control arm bushing? Tie rod? Bent Axle? Steering collar?
Lexus RX 2010-15 :: High Frequency Vibration Mostly In Seats Above 60 Mph
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.
View 6 RepliesTouareg :: High Frequency Buzz Through Steering Wheel Just For Second?
Every so often, and only when turning left at a very slow speed, just for a spilt second there is a high frequency buzz that I can feel through the steering wheel. It makes no sense but I can only assume that it has something to do with the power steering. I have driven a lot of vehicles in my life and this is a new one for me.
View 3 RepliesSonoma :: High Frequency Vibration After Driving For 30 Minutes On Freeway
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.
View 2 RepliesElantra HD (2006-10) :: 2009 - Audio Or Other Source Of High Frequency Hum
I drove this Elantra on a substantive test ride myself and initially as passenger. In twiddling with the interior with radio off and engine off, I have noticed an audible hum from the electronics. The hum disappears when the key is turned off.
This is not a loud hum but it is noticeable to me. I think it is normally masked by the air circulation/heat or use of the radio. Is such a thing covered by warrantys? Everything works in the car so I don't know how to describe the complaint to service especially since they might not hear it.
Ford F-150 (2009-2014) :: High Frequency Vibration Very Noticeable At 45 - 55 MPH
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?

Tiguan :: 2011 - Loose Clunk In Front Going Over High Frequency Bumps?
Have just picked up a 2011 Tiguan Highline, and there is a loose clunk in the front going over high frequency bumps in the road. I own a MKIV Jetta TDi and it feels similar to bad sway bar bushings on my MKIV, however it's not the bushings on the Tiguan.
I crawled underneath and tried to find looseness in the suspension with no luck. The sway bar end links seem tight (compared to the MKV Jetta I also have), and the strut mounts do not seem to be loose.
What I did find were some suspect control arm bushings. I'm new to suspension noises in this platform, our MKV has been flawless for the past 7 years. Could these worn bushings cause a loose clunk?
I also checked the subframe bolts and fuel lines that come up in common searches.
Camry 2012+ :: Intermittent Buzz Or High Frequency Vibration Under Slight 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....
Subaru - Outback :: 2004 - Slight High Frequency Vibration At Highway Speeds
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 ?
Ford 7.3L Power Stroke (1999-2003) :: High Frequency Squeal When RPM Passed 2300 - 2500
Anytime I run the RPM passed 2300-2500 I get this high frequency squeal. I don't seam to lose any performance, but very annoying. Is this the turbo having troubles. It's directly related to the RPM'S. Other that that, the truck runs great....
View 14 RepliesPassat (B7) :: 2012 - Regular Frequency Sound While Driving On Highway
This is on an 2012 SEL, 34K on it. Since the last couple of months, I have noticed that there some wub-wub-wub sound coming the wheels, well, at least from the road surface while drivng on highway speeds.
The sound is just like something is touching the tires, but can't be sure. I may have sensed some very minute shaking as well which may seem correlating with the wub-wub frequency. But as you can see, I am not quite sure how describe it. It is not a distinct sound, not something very obvious. But it is there. I asked my SO too, and both of use can notice the sound independently, so it is perfectly reproducible. The sound appears to be coming from the front, but it is hard to pin point. I also tried opening the window at 65 mph, but the wind and road noise just drowns out all other sounds.
I have thought of getting its wheels balanced as the first step. Went to Costco but apparently they balance only the wheel with tires sold by them on them. I am thinking of taking it to the dealership but want to be prepared by some basic info myself. Hence this question. Hopefully, they wont come and tell me that the wheel drive shaft or some such needs to be changed.
