Gen 2 Prius :: Too Much Radio Frequency Noise Generated
Aug 21, 2012
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.

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.

It's been a while. Am loving my 08 Prius that I bought in October but now that things are warming up, I can see a problem with heat generated by the dark dash under that expanse of glass. Do the lighter color dash mats work much.

I have an RX400h with about 100k miles.
The car's ML Stereo System recently started to go mad a bit: Let's say I am listening to an FM radio station on 103.3 frequency. From time to time I notice that sound quality goes bad and I can notice on radio screen that frequency changed from 103.3 to 103.25. After hitting memory button again 103.3 comes back, but after a while the problem appears once again.

So my check engine light had been on intermittently for the past few weeks. I thought it was for the oil change as it was about that time and ignored it.

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 ?

I recently leased a new 13RX350. Something I find really annoying is switching the radio between FM/AM/XM. When I press "mode" on the steering wheel to change from one frequency to the next, the pre-set stations do not follow. What is I mean is if i am listening to XM Radio, and then I press "mode" to switch to FM and want to press the up/down to change the channel, I still get the XM Radio channel. The pre-set list does not change to FM and its such a hassle having to use the control console and scroll up 6 lists of pre-sets to get to FM. I'm wondering why Lexus did not make this more intuitive?

I need some speaker upgrade recommendations that'll fit into the door cards - specifically the subwoofers - I've replaced an OEM speaker in the driver side once already and it's doing the same thing as before it has a weird vibration/rattle noise with certain freqs. It may very well be the way it's sitting in there but I doubt it.

I have been recently working on a 2003 1.8T fwd Passat that I have owned since new. I recently changed the front rotors, pads and CV axles. At low speed everything is great. No vibrations or unusual harshness. Starting at about 35 mph a low frequency driveline noise starts from the driver side and starts to get drummed out by engine noise above 60 mph. The noise is not very noticeable from the passengers seat. Initially I suspected a tire, but I swapped tires front to back and the noise didn't change. I have tried loading and unloading the front tires in 45-50 mph s-turns and the noise doesn't change.( I was thinking wheel bearings). I put the car back up on stands and tried hand spinning the wheels. No unusual noise was present. I have not found any clearance issues where there might be something rubbing. I got the axles from Raxles and am at a loss. Could this be a wheel bearing or a bad CV joint? How can I tell?

I am looking at a 2006 toyota prius with 88,on it, and it looks like the transmission oil has not been changed on it yet. Recommendation is that transmission oil be changed every 60,000 miles. Would it be "safe" to buy this car considering everything else checks out with a local mechanic? The car is very very clean, almost new tires. Engine oil was changed regularly.

I bought these lights on ebay. It was direct replacement for stock and it has Fan and ballast built in. Light is good and all good but im hearing some low frequency humming noise when im inside car and waiting in any traffic light.
I also opened the hood and tested it is there but less. Im hearing more in cabin. When i turn off the lights its gone. Is it the fan ? How to control it.

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.

My '04 Silverado makes a weird noise when switching it on or off. It also makes the noise when switching between floor and dash vents. Best way to describe it is a low frequency grinding sound. I'm not talking about the clicking sound that seems so popular with this model truck. It has that too, but this is something different. It does it every time I change a setting on the AC. It does not occur when changing from cold to hot.
My truck also has the issue where it will blow cold at first then blow hot air just on Driver side. Turning the truck off then on seems to fix that.
I've googled around but don't know enough about HVAC systems to know exactly what to search forand how to fix it?

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.

I have a very strange electrical issue and CarMax is unable to find the source.
Detail of issue: It started 2 months ago before i left the country i took my car in to get the dreaded valve gasket cover and alternator and after taking the car back i left for Europe for 2 months. I was informed after 2 weeks that my car battery died and had to be jumped.
When I returned home I notice the following issues
1) Alternator Whine in my Sound System
2) Low frequency noise synchronized with engine rev that was triggering the sub low end making a very distinct wooom.
3) Sudden Power Loss for my secondary AMP. The base would cut on /off.
4) Light flicker in my Dashboard (only the GEAR LED) and the entire climate LCD. flicker also synchronized with engine rev.
5) POWER drop on the air con fans while breaking (the RPM would drop)
6) I saw the headlights where also flickering at the same frequency with the LCD and dash led a very noticeable flicker.
7) my headlights would dim when breaking.
8) My Car would start a bit slower (not as instant as before).
Initially i thought it was the my secondary amp that was causing the issue. I took the car to a great Audio shop and they said the On board Hyundai amp was sending weird signals. They said it was broken and i should have it replaced. I told them to disconnect the AMP from the car and leave it disconnected until i take the car back to Carmax.
I was hoping that was the cause ... it wasn't the lights keep flickering (at a far lower intensity probably due to the lower power consumption overall).
What could cause all of this. Alternator I had the alternator replaced two weeks ago (apparently it was broken). I changed 3 alternators in this car. Valve Gasket, Valve Gasket(they were retarded and didn't listen to what i told them) and broken.

I let my friend drive my 1999.5 2.0L Jetta (Automatic). He attempted a drift around a cultist, when he started the drift the car made it's usual noise. But after the sharp turn and acceleration, the car made a higher pitch noise. It was definitely noticeable. When driving back home the car performed all the same, accelerated and turned as per usual. But the noise still remains. I don't know what is causing it to make the noise, maybe the Transmission? I'm not too knowledgeable when it comes to cars so that's why I came here.

My 2003 Honda Element sometimes generates a vibration that feels just like driving down a washboard dirt road. You know one that the ridges are very close together. This only happens around 40 MPH with a load on the engine. At first I thought it was a wheel, tire or suspension issue. But I can make it stop instantly by pushing or releasing the gas pedal. So this leads me to think it is transmission related. This is a automatic. I would like to see the car sometime but would not feel right about passing on this problem without knowing the cost to fix it. Stumped in Seattle.

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).

2003 Jeep Wrangler LOUD squeal when coming off the accelerator. I've had changed the Tension Pulley, The Belt, Checked the Power Steering, Removed the belt from the AC unit..smaller belt now....Tested the Alternator, it's working like a champ. I have a 4.0L 6 Cylinder. My mechanic wants to check the intake gasket and another intake which he spoke of and I can't remember at the moment however with no guarantees these or one of the two could be the problem. He expects it to be a 5 hour job. The sound seems to be generated from the lower backside of the engine...

I have a 2007 Gen II with 133,000 miles and am using Amsoil synthetic oil and an extended life filter, changing oil every 10,000 miles. What is the frequency for changing belts, hoses, and timing belt? Other than a faulty latch on the rear lid, I have experienced ZERO problems with the car and would like to keep it so.
