Lexus RX 2010-15 :: Loud Humming Coming From Under The Car When Turned Off
Jan 29, 2014
Not sure if my 13' rx350 is haunted. Went in the garage (car had been sitting for hrs) and heard this pound humming. Checked everything in the garage and kneel down near driver side /passenger door and could hear the humming coming from under the car. Checked to see if the radiator fan was running ..nope. This has occurred on 2 occasions that I know as it seems to be random so I am concerned if I take it to dealer I'll get the "can't duplicate"...

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...

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 keep my 2015 RX 350 in the garage, and last night I noticed a humming or buzzing noise coming from it. I switched the ignition to accessory position and turned it off and the noise stopped. A search here turned up many discussions noting is is the gas evaporation leakage check valve and it is a normal function of the vehicle. My question, is this some sort of pump that is running and causing battery drain?

Odd, relatively loud "whoosh" noise when they turn off the engine? It sounds pneumatic in nature, like a pump or servo of some sort sealing or depressurizing? I should note that I park in a garage, which may amplify it. Definitely more noticeable if you open the driver door or window then kill the ignition.
Second, I don't know if it's the cold, a bad batch of gas, or just normal but the motor seems to make a clack clack clack noise when stopped/at idle. It's not consistent and doesn't seem to affect drivability. I just hope it's not knock or slap, i.e., indicative of serious issues. Am I just being paranoid and overly sensitive?

Checking my garage before going to bed last night and hear motorized humming coming from rear of the GX. I slide underneath and it seems to be coming from the spare tire area. I started the engine, then shut it off and the noise went away. The noise reminded me of the air suspension pump on my old Denali, but my Gx has the standard suspension.

This is a first for me. Came in last night after my 140 mile commute and pulled into my garage and turned off my car ('16 IS350F). This morning(approx. 10 hrs.later) I went into the garage and heard a humming noise. I thought it was the refrigerator, but as I walked around the back of the car,it was obvious the noise was originating from the right rear. It sounded(to me) just like the fuel pump running,but that made no sense as it isn't on the "hot" battery bus...ie: it doesn't run until the accessory power is provided. I got in the car and cranked it....let it run for a couple of minutes and shut it down and the humming stopped.

Today I went in may garage and heard a humming from the rear of my 2014 prius. I assume it is the hybrid battery. This was several hours after the car had been driven. I turned the car on and then off and the humming stopped. Is this normal? I know it is common for it to hum immediately after you turn the car off for a bit, but several hrs later?

First of my truck is an 03, xlt 4.6 5-speed with 82,000 miles. Almost always when i come to a stop i can hear a faint humming that is coming from the engine compartment. There is no pattern or set way that this humming happens, it just comes and goes when at idle. As soon as you put load on the motor it will go away. I got under the hood today and fired it up, nothing, gave it just a little throttle and sure enough here is this odd humming. It is coming from in the air intake. Also while i was under there i noticed that the cable that is right next to the throttle cable is very loose, i am not sure what this cable goes to or if this could be part of my problem

I am trying to diagnose a sound that is coming from my 2001 Camry 2.2L. When I accelerate there is a load humming noise coming from the engine. It happens at all speeds and only when I accelerate.

1999 ford expedition 5.4L ....I have been hearing a loudish (I can hear it in the cab) humming noise coming from the engine bay. I don't hear it when the truck is cold (1 to 5 minutes after starting), seems to get louder at it its peak (the more I drive). When i open the hood, the humming is coming from the intake. I am a pretty handy guy, just at my witts end right now....not sure, but I was thinking brake booster?

As I accelerate, there is a humming noise that comes from the transmission area of the car. It does not make the noise when I am in idle, nor if i put the transmission in neutral and rev the engine.
When driving slow the noise is very subtle. As I accelerate faster the noise gets louder. The noise becomes the loudest at 60 mph. Above 60 it seems to calm down some. The noise is like a constant, deep humming sound. The noise gets softer as I slow down and then is gone when at idle again. To me it seems related to the speed of the tire or the CV half shafts turning or something rubbing in the transmission as the car goes faster. However the sound doesn't change when the transmission shifts. It stays constant and only gets louder as I go faster and then softer as I slow down.
While driving and turning hard to the left the sounds almost disappears until the car straightens out again. I have replaced the struts on all four wheels and this seems to only have caused the sound to get louder. I have also inspected the CV joints. There doesn't seem to be any cracks or signs of wear to all 4 joints. And I repacked the bearings.
The only other things I can think of is the cv half shafts are actually bad and need to be replaced. Or the motor mounts are not aligned/worn out and need to be replaced. Or the kickdown band and low reverse band on the transmission need to be readjusted. Or the transmission is has a problem (however it doesn't slip when driving).

As I begin to accelerate a humming sound from the front of the car begins. The noise becomes more pronounced the faster I go. No additional noise is made when I brake or turn, nor does it appear to be any noise when I went in reverse. I made a 180 mile trip on Sunday with no problems, although I did travel at closer to 55mph than 65. The car has 170,000 miles on it and has had most of its scheduled maintenance performed.

2007 GS 350. In the past 6 months i have changed my FRONT brake pads with two different pair. First was a generic pad(REMOVED), and did some research then went for Akebono(CURRENTLY) brake pads 2-months noise-free and now back to braking noise dilemma.
Issues:
-In the morning, first 3-5 pressed brakes makes loud(REALLY LOUD!) humming noise then goes away. Feels like the brakes are rusty but it continually does it everyday. I just got the car serviced so assuming all my fluids are filled.
-Randomly, on a fully stopped brake i hear a whistle noise from the front brake. NOT as loud described above.
-I noticed the noise happened the most on HOT weather, and occasionally on COLD weather.
Longo Lexus advice me to buy an OEM brake pads and should resolve this problem. I'm also thinking of just getting it done at the dealership and pay that extra cash plus warranty.

I turned off the engine and I get a whirring sound, quite loud, that seems to be coming from the top of the engine around where the injectors are.

My car is usually garage-kept. Last week, I left it in an outdoor parking lot at the airport for 5 days, with temps ranging from 5 to 20 degrees. When I returned and turned it on, it responded with a very loud and visible shudder that lasted about 20 seconds. It gradually diminished, and then was fine. I've been driving it normally for two days, with no more symptoms. But this morning, turning the car on in the garage, it gave me the shudder again, this time for only about 5 seconds.

I have a 2015 IS250 Base with TRANNY PROBLEMS
After 185 miles on the vehicle, I reported the problem to Lexus and the Tech that test drove with me said I was hearing things. Apparently there was a humming noise coming from the transmission.
The noise became evident and consistent, took it back in again, the Tech says its normal and DI engines make a lot of noise.
After six months and 2700 miles the noise became annoying, Tech said they will look into it and confirmed it is unusual. Test drove about 5 other new 2015, used 2014's and no humming noise present.
Engineers made two trips over a five week period from Cali. They changed the alternator, which at first they thought was the problem, then they started looking at the fuel pump on the engine, then they swapped out a tranny from a loaner and the noise disappeared. They took out the loaner tranny and ordered a new tranny and installed it.

Recently purchased a 2002 sc430 . After an hour of driving I began to hear a buzzing or humming coming from the backseat on the passenger side . Sounds almost like a fan. Car drives just fine but the buzzing is driving me nuts.

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 ?

I own a 2006 GS300 for 4 years and I have about 90k miles on it. Just suddenly today when I went to go turn the car on, I hear a rapid loud clicking noise and the engine will not start. I've done some googling and one possible solution is to disconnect the battery to let the car reset and then connect it back. What the cause is? I've replaced the spark plugs a few months ago, but I didn't replace the battery.
