Lexus GX 2004-09 :: Whining / Humming Sound While Moving And Not In Neutral With Engine Rev
Oct 6, 2013
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.

I have a 2006 lexus es 330 that just turned over 90,000 miles. My dad and I have done the regular maintenance on it so far but this weekend after a 3 hour drive, I turned the car back on and a loud whirring/humming/whining noise was coming from the engine. It gets slightly louder with acceleration, but I can barely hear it once I've picked up speed (but it's still there.) It still happens when I am in neutral. It sounds like it is coming from the passenger side of the engine. Close to the power steering pump area, but the power steering fluid is full (although it is a very dark/black color and has a slight smell...not sure if this is normal.) I'm not having any trouble or hesitation while steering. The rack is operating smoothly and it is not leaking. I plan on taking it into the shop but wanted to go in educated.

I have an 03 Exp 4x4 Limited with 4.6L V8 with 167K on the clock. I'm getting a kind of humming rotating sound out of the front end when moving. The frequency definitely goes with the wheel rotation speed and the noise is the same with the trans engaged and when coasting in neutral. The noise is present at all speeds but becomes more of a humming sound as the speed increases at highway speed.
I've had both front wheel bearing hubs replaced (they were completely shot), brake pads and rotors replaced, and just had new tires. The rotating sound is still there though. What else is there that could be the cause? Is there another set of bearings somewhere in the front end?

I hear this humming sound when hit 70mph and I am on the gas. However it lasts till 73mph or so and go away!. Below is the pattern I observed;
1. On gas (accelerating), when hit 70mph (not even 69 mph) I start hearing humming sound. It will last till 73mph and goes away. Not able to pin point the source. I feel it is originating somewhere closer to transmission shift.
2. Decelerate from above 73mph and no gas given, when hit 70 I don't hear the sound. Press the gas pedal, I hear.
3. Set the cruise at 70, I hear.
4. The hmmmm sound appears only between 70-73 mph speed and while on gas.
What is this sound?. What is the source?

Since recently buying my 2008 GX470 with 100K miles I have been trying to find what is making a low rumble sound when moving. I have checked everything underneath, tightening up a few things etc. to no avail. However recent experimenting with the shock settings from comfort to sport. It seems that the rumble is less when it is on comfort. So I am thinking the shocks themselves are making some noise.

Finally got the Tech to acknowledge the Humming/Groaning from the Engine as I sat behind the wheel at my 5000 mile service visit. His response was that the sound we were hearing ( at start-up) was "NORMAL"
The RX drives and sounds fine after that mileage, but many times my destination is less, and I feel like I am driving a reject.This has persisted since new, @ frigid and high temps; as we approach 7500 miles.
Engine sound varies in pitch when acceleration increases the RPM's ?

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?

So there is a loud humming sound as I would describe, coming from the passenger side glove box when I turn my fan to run at high...

My 2008 Prius had a front quarter panel replaced after my wife back in to a fire hydrant.The body work looks fine , no issue there, but now when the car is coasting with the gas engine off you can hear a humming sound that was not there before the repair.Also it does,nt seem to be recharging the hybrid battery at the same rate.My thought is maybe the body shop caused some damage to MG1 by spinning the front tires on a emision testing machine or rollers.Does special precautions would have to be used when testing wheel clearances after a quarter panel replacement on a hybrid? Would a body shop need to do this ?

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.

I purchased this 2001 Passat with 138,000 miles on it approximately 4 months ago. Since the purchase I have had the timing belt, water pump and tensioner belt replaced, also replaced the valve cover gasket, plugs, plug wires, back brakes, back rotors, bushings and linkage in sway bar. Now it is making a whining noise when accelerating and when the engine is revved while in neutral. The power steering fluid is between min and max. What this could possibly be? I am about at my end with this car!!!

My wife's 2006 Prius is having some problems. The car has 187,000 miles on it. When the engine starts it makes a continuous whirling or humming sound. WHen I try to drive it has minimal power and can not be driven above 15-20 mph on my street. I bought an inexpensive Actron code reader and got the following codes. P0A92 P0300 P0303 P0304 P3191. Does it sound like a definite transmission problem and those other codes are caused by the transmission problem.

I just bought a truck, it has a whining noise while accelerating, stops while letting on the gas, does not do it in neutral even if i rev up the engine. Only whines while there is some force on it, ie.. accelerating, or going up a hill at any angle, and does it from about 10-15mph- atleast 60mph.

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.

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.

What could cause this? I have 100k and I only notice this if in park or neutral at 1500rpms. It goes away before and after and it seems to drive very smoothly. I had a bad alternator and I just replaced it but the "new" one is making a high pitching ringing so I'm having the shop change that out for a new oem. Any chance it's the alternator or could this be something else. I have sea foamed the throttle body recently and cleaned the maf recently and changed the air filter. I didn't do plugs but they are do at 120k

2013 ES350 silver for my wife - bought 3 months ago and drove 600 miles.
About one month ago, I could hear a humming sound at the back of the car (somewhere around backseat or in the trunk). At that time, car was parked in the garage. This sound is similar to having several honey bee in that area and humming at the same time. The sound disappeared by itself after several hours.
Yesterday, it happened again. We parked the car in the garage around 4pm and did not hear this sound at that time. At around 10pm, when I went to garage to get some tools, I heard this humming sound again. This morning, as soon as I woke up, I checked the car and the sound is gone.
I am not sure if there are any other reports of similar issue for 2013 ES350, or maybe this issue is just for my particular car? And this humming sound is not always there, so I am not sure how to repeat it in the repair department. Maybe I need to bring it to delaership and just let service technician take a look.

My ES350 is always parked in my garage. One afternoon, I went into the garage to get something and I heard a humming sound coming from the car. It was very hard to identify where it was coming from. It sounded like a low horsepower compressor of some sort. I put my ear next to the rear wheel on the drivers side as this was the area the noise appeared to be coming from.
This is the second time I've experienced this happening. A couple things to note:
1. The car had not been operational for at least 8 hours.
2. There was no indicator lights on the dashboard flashing.
3. All doors were closed.
4. It seems to happen intermittently and I can't replicate on my own.

My 2011 ES350 has 49k miles on it (just got it last week).
I just noticed that when moving slowly (with and without accelerating) I can hear a slight whistle sound that resembles a bird chirp coming from what I think is a wheel.
My dad can't hear the sound (I'm thinking the frequency is too high for his ears) but it is definitely there and I can hear it clearly.
The sound comes and goes but something is not right. Wonder what it is?

I have a 2005 Suburban Z71 and when in 2wd it will run for several miles then just stop moving like it is in neutral. In auto 4wd it runs just fine. What could this problem be and will it be okay to drive in auto 4wd until I get it to the shop?
