Lexus GX 2004-09 :: Whining Sound When Stopped On Gas
May 15, 2016
Couple of days ago when my wife turned the car on and started driving, the battery light came on and when she stepped on the gas it made a whining sound. Also when she moved the gear into reverse, the door locks did not lock automatically. Once the car was driven about 30 minutes and she got on the highway, the battery light turned off and the sound went away. I was not able to replicate that issue when she arrived that night or the next day.
Should I just replace the alternator even if the problem does not recur?

2007 GX470 - Just noticed a distinct whining/humming sound similar to tire hum you would have with aggressive off-road tread tires. Seems to come alive around 20mph (or at least that's when I can hear it) and gets louder with the increase in speed. As I slow the sound goes away. Only does it while moving and not in neutral with engine rev.
We bought the car at 59k and it just hit 70k . Only oil changes, tire rotation have been done since we bought it. The tires were new when purchased so they have about 10k on them. No noise when we first got the car so I tend to think it's not related to the tread.
I was planning to do the front/read diff and transfer case drain/fill. Wondering if that may be the cause.
Something else - at low speed in tight turn (i.e. backing out of garage, pulling into parking spots) I do feel some roughness - almost like the differential is locked. Not sure if that is an indication. Was thinking it may be a wheel bearing but there is no clunking when turning.

So I'm driving home late at night, few cars on the highway, I turn off the radio and I hear a faint, very high pitched whine coming from the engine bay when going 40-50 mph. It sounds like an electric motor spinning at high speed and frankly it's a bit irritating. The sound is there whether the engine is running and charging the battery, the car is using the traction battery or it's coasting and regenerating power. The sound stops for a moment if I gently accelerate and then lift off, but it comes back on coasting.
It's different from the louder, low pitched subway-train sound that comes from regen braking at low speed. Could this be the dreaded CVT whine reviewers complain about? Or is it the normal sound of the MG1 unit? This car is really quiet so weird noises pop up more.

I have a 2004 Explorer 4.0L with 190,000 miles. My wife was driving it and the vehicle stopped moving. Sounds like the torque converter whining and will not drive in any gear or 4wd.

I own a 2013 ES 350 with 5000 miles.
On cold weather conditions, doing a cold start, I allow the engine to run and warm up for a minimum of 5 minutes before driving. In this time frame the engine goes thru the whining sound and then the engine noise is quiet (normal).
What do other owners allow for engine warm up time before driving.

Back story, I've been borrowing my father's 2008 Prius off of him since I took a new job and my Tacoma doesn't get the best mpg, and finally purchased it off of him. Its making a new sounds though and he wants to get it fixed if its something major.
Its a quiet peeping that can be heard inside the car when coming to a stop (just when its quiet.) I've tracked the sound down to the engine bay but cant pinpoint where it is exactly, somewhere on the drivers side and its more of a pulsating whining sounds. The water pump was replaced about 10k miles ago at 65k miles under warranty.

My Honda Accord 2004 is making a whining sound when I start it up. It fades while driving buy it comes back every time the car accelerates from 1st to 2nd. It is an automatic but it is about that time frame that the sound occurs.
I've checked most things but am no expert. Transmission fluid, power steering, antifreeze, battery are all topped off and I just had an oil change (where I did use regular vs. synthetic which might be a factor but I don't know).
I also recently had the serpentine belt fixed but it sounds like the noise is coming from that area when the hood is up.

My left headlight has been going off periodically, so to confirm that it's the bulb, tonight I switched the bulbs from left to right/right to left.
The job went very smoothly. It took me about 20 minutes, but I took my time. I buttoned everything back up and turned on the lights. Both sides came on, but I immediately noticed a very loud buzzing/whining sound coming from both headlamps. It is very loud and I know I would have noticed it before at some point over the course of the last three years that I've owned the car. Obviously, this is not normal, but I can't for the life of me figure out what I could have done wrong, if anything.

About 2 weeks ago, my 2004 Honda CR-V (176K miles, manual transmission) started making sort of a dry, whistling, whining sound. It's not a grinding sound but more like wind whistling through something metal...? I think it's coming from the right back wheel or wheel area. It doesn't start until I've been driving maybe 6 or 7 minutes, and usually kicks in above 40 MPH although I've heard it when going slower, too. If I jiggle the steering wheel the sound stops and starts. It also stops when I go around curves or make turns. At first it was happening all the time, but over the weekend it seemed to be diminishing.
I did record the sound on my phone and uploaded the video to the following link: [URL] .... You can hear it stop at about 16 seconds and then start again at 20. Also, starting at 35 seconds I stop for a light and then restart at about 1:10. So you can see how it kicks in as I start going faster. No jokes about my shifting or driving or the dog panting in the background. I'm sure the vid will go viral.
I took it to a mechanic Monday but he only heard it for about 3-4 seconds. He put the car on the lift and inspected the wheels but didn't see anything obvious so is chalking it up to old car syndrome. So, do I seek a second opinion? Is this something obvious for CRVs? I just want to make sure the bearings (or something like that) aren't going on it.

My "05" Prius has 164K, I'm the original owner and I have had great success with this car. I know some owners talk about the loud whining humming sound from the A/C unit which I am aware of but this newest sound is different and after 4 hours with a Toyota tech all they can come up with is an A/C compressor going bad. I only hear this sound after I reach 40MPH+ and then decelerate. It then winds down with the speed of the car sometime intermittently. If I accelerate it goes quiet.
I've also tried speeding up to 40MPH and then move into neutral. It will stop the noise. I'm adding a video and I realize there is standard road noise but if you watch my energy monitor you will hear the noise whirring winding when the green arrows point back to the electric motor. Pay close attention to the viseo frames at 13 seconds, 22 seconds and again at 29 seconds. Turn up the volume. Of course inside the cab it is much more pronounced. I'm finding it hard to believe this is an A/C compressor. Sounds more like an electric motor whining/whirring. I'm concerned about driving my car for safety reasons.

When my truck sits all day and its cold out, my truck in 2WD will make a whining sound going down the road, sometimes its a grinding sound almost. Appears to be coming from the passenger side of the truck towards the front. Engaging 4x4 gets rid of the noise, and the noise will usually disappear after the truck has been running and warmed up. I've changed my ball joints recently and everything looked good and yes it had done it a time or two before hand. What causes this, and how do I fix it?

2008 F150 HD Payload package with 5.4L and 4spd auto, 61,000 miles.
Recently developed a whining sound coming from the transmission or somewhere else in the drivetrain. Does not sound like rear axle because it changes pitch with the change of gears. I proved this by disengaging OD while driving and the whine was higher pitched once the transmission down shifted. I did some other research and found a reference to the #9 bearing going bad in a 4R75 trasnmission in a Crown Victoria. I am going to fight for any repair to be covered by the powertrain warranty even though it just clicked 61,000. The dealer has done ALL maintenance on this truck since it was new (following severe duty recommendations).

I have a 2005 STX with the 4.6L, 4WD, AT.
The engine has started to make a loud whining sound recently. I replaced the belt and tensioner since it was original and had 93,000 miles on it. The sound is still there.
The sound increases with rpm but doesn't change when you turn the steering wheel.
The engine starts and runs smoothly with plenty of power.

We have 3 company work trucks. They are F150's 2WD V6 - one is a 2008 and two are 2007s. They have all had thrust bearing problems. We just had the #9 thrust bearing replaced in the 2008 for the third time. The trans hasn't failed but starts making a whining sound at all speeds which varies in pitch relative to speed. The 2008 has had it replaced at: 40K, 60K, and now 70K. One 2007 had it replaced at 60K and 90K. The other 2007 had it replaced at 50K.
Our dealership says they've never seen anything like it & that our trucks are the only ones they've seen this on. They are suggesting it's happening due to driving behaviors. All 3 trucks have a single driver and aren't switched or shared. The 2008 doesn't carry or tow. The 2007s both carry hundreds of pounds of tools daily. This just seems like too much of a coincidence to be driver induced and that we're the only ones with these issues.

So about 3 or so weeks ago I brought my 2006 GX470 into the Lexus stealership and had the pulley's, water pump, and timing belt replaced. Fast forward to this morning, about 300 miles driven and it suddenly when started today has a terrible whining sound and the battery light is on the dash.
I need to go over the invoice from what they did but I believe it was 4 different pulley's they wanted to replace. Not sure if it was anything on the accessory belt path, but I imagine if I call they will blame the alternator and tell me to shell out hundreds more?
I didn't run it long like that, only a minute or so. Popped the hood and I could smell the burning rubber smell so I quickly shut it off. Nothing *appeared* seized to me however.

I had the cam gears on my 2009 RX350 replaced and after the replacement I noticed that the engine noise is louder. It's louder after a cold start and idle. And it's louder when driving. Even the transmission sounds like it's struggling - it's taking much longer to shift into higher gear and occasionally it makes a whining sound when it shifts. Also, I'm hearing whining sounds when I steer the wheel (which was diagnosed as potentially caused by a faulty power steering pump, which by the way did not cause any noise prior to the work done). The replacement was done by a reputable Lexus dealer.
The Lexus dealership claims that the engine noise level is within acceptable limits even though it is much louder than before the cam gears were replaced. They deny that the replacement cam gears could be defective or that the replacement itself could have gone wrong. They have acknowledged the noise coming from the transmission and have offered to replace it (still under warranty so no cost to me). Now what is strange to me about all this is that prior to having the cam gears replaced, the engine noise was very quiet. The only occasional noise came from the cam gears on cold starts but lasted a second or two.
Now I don't know for sure that replacing the transmission will fix the noise issue. And it is so strange that the transmission seemed fine prior to the work done. What's happening here given the facts? Could replacing the cam gears somehow damage the transmission? Is there any interaction between cam gears and transmission. Aside from the transmission, what could explain the much higher engine noise (when not shifting so transmission not a factor) after the cam gears were replaced?

The sound system in my 2008 LS 460 suddenly stopped and a loud thumping noise comes up in all speakers even if the radio is turned off. There is no music at all only that loud noise. Bluetooth does not work as well as command voice and the GPS guiding system. I had to remove the fuse to stop the thumping sound. To answer my telephone I must pull on the side of the road and turn off the motor. Car dealership said that it is the first time they see that. The car is scheduled to be looked at in a couple of days.

Driving down the road today listening to radio in my 2007 LS460. The sound suddenly stopped and just a repeating loud clicking sound is heard. No radio, CD, or Handsfree sound, just annoying clicking even when audio is off. Turned off car and restarted. Same clicking. Disconnecting amp in trunk only way to stop clicking noise.

Ok, so about 3 months ago I noticed the fan was blowing kinda loudly, but stopped. Then 2 weeks ago, my AC just stopped the next morning it started blowing again, then 2 days later it stopped again and hasn't come back on. When I try to turn it on I can feel a light trickle of cool air but I don't hear the fan. .. what does this sound like?
