Lexus IS 2014+ :: Humming Noise Coming From Transmission After 185 Miles On Vehicle
Oct 19, 2015
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.

Faint humming/whistling noise coming from the drivings side of the motor. I can hear it when I put my head next to the drivers wheel well, and most certainly from that side of the motor when the hood is popped. It's not super loud, but it is noticeable. I know we have Direct injection motors, so I know that ticking is completely normal. Am I overlooking this and being paranoid? Car has 2100 miles on it. I don't know if it was there when brand new.

So I went into my garage last night to shut the door. I heard a slight buzzing/humming noise coming from the car. I narrowed the noise to under the truck of the vehicle. It sounded like a fuel pump was running. I don't know when it started, but it was about 5 hours after the car was driven last. After a little research, I found this in the manual page 8:
"Approximately five hours after the engine is turned off, you may hear sound coming from under the vehicle for several minutes. This is the sound of a fuel evaporation leakage check and it does not indicate a malfunction."
I started my car and it stopped after that. Could this be The case of why some people have dead batteries on the 2014? Maybe this runs to frequently or stays on too long?

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).

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.

2015 IS350 AWD ... Lately I have noticed on a cold start that when my idle is between 1000-1500 rpms, there is a slight buzzing/humming noise. It goes away if I rev the rpms past 2000 rpms and also when it drops under 1000 rpms. It's almost like a droning noise. I can hear it inside and outside the vehicle when the rpms are in that range. I feel like the noise is made at a certain frequency and it causes a vibration to occur.

This morning I heard a "strange" buzzing noise coming from the rear of the vehicle and I don't know what it is.
As background I drove my IS250 for about 1hr yesterday and parked it for the night around 10pm inside a garage. This morning at around 7am (9 hours later), I came down to the garage to hear the buzzing "fan" noise. I am not sure what it is. The vehicle was OFF. I managed to record the noise.
IS250 Buzzing noise - Car OFF for 9hrs - YouTube ...
That said, the buzzing noise couldn't be something left on overnight... since the battery was fine. The car proceeded to start just fine. What do you think it is? Can it be some sort of fuel vent pump or something?

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?

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.

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.

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.

I have done some reading of past threads regarding both Gen 7 Camry with people having an issue with a strong smell coming from their vents after perhaps 1K miles or less on their vehicle. Looks like some people had it fixed (some fixing it by themselves) while others continued to experience the problem. Similar thread regarding Toyota Camry Hybrid but only brief thread. Then another thread regarding perhaps another smell like from plastics /battery (?) in Prius while I was on the Prius threads.
Has this problem been addressed/resolved either by Toyota or by owners who simply fixed it themselves? I also do not know if the Prius offensive odor (someone who was testing them noticed it while test driving) is a totally different thing (like I say someone said it was from plastics or battery itself, not sure.... )
These are things I never even thought of /considered when looking for a new vehicle, and never experienced in my older Camry.

The front end on the ex started humming really bad today after driving 350 miles to Memphis Tennessee. When I noticed the humming I pulled over and unlocked the hubs thinking the front axle is low on gear oil. No change when back on the interstate. If I turn right at highway speeds the noise completely goes away. While driving straight its pretty loud. The more I turn left the louder it gets. Just had the front end apart to do all ball joints tie rod ends etc. the hubs looked great and didnt have any play at all. The noise happens between 40-65 mph. After 70 mph the noise goes away. Doesn't go away when I let of the pedal, hit the brakes, put in neutral while driving, or accelerate. Could it be the hubs?

Enjoying some nice below zero weather in Chicagoland. Getting a bit of a squeel for the first couple of miles from my 2012. I think it may be a belt.

2007 Camry LE 2.4
I just replaced the rear pads and rotors with no issues other than having to bang the cr@p out of the left rotor with a hammer to get it to come off. Now at pretty much all speeds I am hearing a rythmic humming-type sound that increases and decreases with vehicle speed. It's not a constant hum but more like one-hum-per-tire-revolution type of sound. It is coming from the left side as far as I can tell.
Thinking I had damaged the wheel bearing (and after searching the forums extensively) I replaced it with a brand new bearing from Advance Auto Parts. I re-checked the pads, rotors, all bolts, everything is lubricated properly, etc. Just took it out for a test drive and the noise is still there. Sometimes it gets louder when breaking but not always. I rotated tires and the sound did not follow the tire. The pads aren't stuck or rubbing excessively as far as I can tell.
This sort of thing has happened in the past on the left rear. It would sometimes happen when I swapped the summer tires for my winter tires on steelies, the left rear would make the humming sound, I'd take the wheel off and put it back on 180 degrees rotated and the sound would go away. I've done that a few times too and it has not worked.

I purchased a 2014 Passat 1.8tsi - had 4 miles when I test drove it.
Now a week later and 100 miles later I noticed a trail of red fluid when I had parked in car port. Leaking transmission fluid. I can see fluid drops on all the bolts underneath the car. I feel like dealer should give me a different car - 100 miles and a problem like this - feel like I have a lemon. Not sure if I should even drive it to them or they should tow it? Why its leaking? -

Heard a noise coming from the wheels? Sometimes it's a squeak, sometimes it sounds like sandpaper going over wood. Makes the car sound really old when cruising. I set an appointment to have it checked, but if they don't hear it, are they not going to do anything? I used to own VW/Audi cars, and they would just say perform as specifications, no issue found. I'm worried that Lexus will do the same. I drove off from the dealer, and there it was again. My car is only several months old with 2500 miles on it...

My truck just hit 110k on the clock, and i've never had the transmission fluid changed. Is this something that I am past due on changing or early? I don't know when it is supposed to be changed. If so is it something that you can do yourself?

Just picked up '14 350 f-sport and I notice a lot of road noise after 100 miles, have about 150 miles on it now and it sounds like the front wheel bearings or maybe the tires? sounds like a rumbling coming from the front. I don't recall hearing it on the test ride, not sure if its normal or not.

I am feeling disappointed just came out of a lemon law suit with a kia optima I bought two years ago. I figured we'll I should buy a better brand this time which my brother recommended cause I was going to buy another Infiniti I always had good things with those cars. But the last 2 nights I have been hearing a squeaking noise in my rear end of my brand new IS 350 F Sport. Only in sport plus mode. I was driving home from work at 2 am and driving through a canyon road cause I want to see how this car does as soon as the road got a little bumpy I was hearing a squeaking noise come out of the rear of the car. Then I get home and I hear it going over my speed bumps in my complex of my condos. So I think we'll that's odd. I take it out of sport plus mode and back to eco and drive around the complex again and it goes away. Remind you I have 484 miles on the car.

Noticed any excessive wind noise coming from driver's side window/door on their 3IS? Maybe because its pretty quiet but I'm noticing a slightly louder than normal "whizzing" noise (wind noise) coming from driver's side window/door..
Something the dealer can adjust / tighten up to eliminate this annoying noise?
